text: Western honey bees are often described as essential to human food production, leading to claims that without their pollination humanity would starve or die out. Apples, blueberries and cherries, for example, are 90 percent dependent on honeybee pollination. Albert Einstein is sometimes misquoted as saying "If bees disappeared off the face of the earth, man would only have four years left to live""." Einstein did not say this and there is no science to support this prediction.


title: Honey bee

text: Many important crops need no insect pollination at all. The ten most important crops, comprising 60% of all human food energy, fall into this category: plantains are sterile and propagated by cuttings, as are cassava; potatoes, yams, and sweet potatoes are root vegetables propagated by tubers; soybeans are self-pollinated; and rice, wheat, sorghum, and maize are wind-pollinated, as are most other grasses.


title: Honey bee

text: No crops originating in the New World depend on the western honey bee ("Apis mellifera") at all, as the bee is an invasive species brought over with colonists in the last few centuries. Tomatoes, peppers, squash, and all other New World crops evolved with native pollinators such as squash bees, bumble bees and other native bees. The stingless bees mentioned by Jefferson are distant relatives of the honey bees, in the genus "Melipona".


title: Honey bee

text: Honey bees obtain all of their nutritional requirements from a diverse combination of pollen and nectar. Pollen is the only natural protein source for honey bees. Adult worker honey bees consume 3.4–4.3 mg of pollen per day to meet a dry matter requirement of 66–74% protein. The rearing of one larva requires 125-187.5 mg pollen or 25-37.5 mg protein for proper development. Dietary proteins are broken down into amino acids, ten of which are considered essential to honey bees: methionine, tryptophan, arginine, lysine, histidine, phenylalanine, isoleucine, threonine, leucine, and valine. Of these amino acids, honey bees require highest concentrations of leucine, isoleucine, and valine, however elevated concentrations of arginine and lysine are required for brood rearing. In addition to these amino acids, some B vitamins including biotin, folic acid, nicotinamide, riboflavin, thiamine, pantothenate, and most importantly, pyridoxine are required to rear larvae. Pyridoxine is the most prevalent B vitamin found in royal jelly and concentrations vary throughout the foraging season with lowest concentrations found in May and highest concentrations found in July and August. Honey bees lacking dietary pyridoxine were unable to rear brood.


title: Honey bee

text: Pollen is also a lipid source for honey bees ranging from 0.8% to 18.9%. Lipids are metabolized during the brood stage for precursors required for future biosynthesis. Fat-soluble vitamins A, D, E, and K are not considered essential but have shown to significantly improve the number of brood reared. Honey bees ingest phytosterols from pollen to produce 24-methylenecholesterol and other sterols as they cannot directly synthesize cholesterol from phytosterols. Nurse bees have the ability to selectively transfer sterols to larvae through brood food.


title: Honey bee

text: Nectar is collected by foraging worker bees as a source of water and carbohydrates in the form of sucrose. The dominant monosaccharides in honey bee diets are fructose and glucose but the most common circulating sugar in hemolymph is trehalose which is a disaccharide consisting of two glucose molecules. Adult worker honey bees require 4 mg of utilizable sugars per day and larvae require about 59.4 mg of carbohydrates for proper development.


title: Honey bee

text: Honey bees require water to maintain osmotic homeostasis, prepare liquid brood food, and to cool the hive through evaporation. A colony's water needs can generally be met by nectar foraging as it has high water content. Occasionally on hot days or when nectar is limited, foragers will collect water from streams or ponds to meet the needs of the hive.


title: Honey bee

text: The only domesticated species of honey bee are "A. mellifera" and "A. cerana", and they are often maintained, fed, and transported by beekeepers. In Japan, where "A. mellifera" is vulnerable to local hornets and disease, the Japanese honey bee "A. cerana japonica" is used in its place. Modern hives also enable beekeepers to transport bees, moving from field to field as the crop needs pollinating and allowing the beekeeper to charge for the pollination services they provide, revising the historical role of the self-employed beekeeper, and favoring large-scale commercial operations. Bees of various types other than honey bees are also domesticated and used for pollination or other means around the world, including "Tetragonula iridipennis" in India, the blue orchard bee for tree nut and fruit pollination in the United States, and a number of species of "Bombus" (bumblebees) for pollination in various regions globally, such as tomatoes, which are not effectively pollinated by honey bees.


title: Honey bee

text: Primarily in places where western honey bees were imported by humans, periodic collapses in western honey bee populations have occurred at least since the late 19th century. Starting in the first decade of the 21st century, abnormally high die-offs (30–70% of hives) of western honey bee colonies have occurred in North America. This has been dubbed "colony collapse disorder" (CCD) and was at first unexplained. It seems to be caused by a combination of factors rather than a single pathogen or poison, possibly including neonicotinoid pesticides or Israeli acute paralysis virus.


title: Honey bee

text: "Acarapis woodi" (or "tracheal mites") are parasitic mites which live and reproduce in adult bees' tracheae, or respiratory tubes, piercing the tube walls with their mouthparts to feed on haemolymph. To infest new hosts, the mites must find newly emerged bees; after three days, the bristles (setae) guarding the spiracles are firm enough to prevent the mites' entry into the tracheae. Mite infestations are known as acarine, and have been called "Isle of Wight disease."


title: Honey bee

text: Larval stages of the moth "G. mellonella" parasitize both wild and cultivated honey bees, in particular "Apis mellifera" and "Apis cerana". Eggs are laid within the hive, and the larvae that hatch tunnel through and destroy the honeycombs that contain bee larva and their honey stores. The tunnels they create are lined with silk, which entangles and starves emerging bees. Destruction of honeycombs also result in honey leaking and being wasted. Both "G. mellonella" adults and larvae are possible vectors for pathogens that can infect bees, including the Israeli acute paralysis virus and the black queen cell virus.


title: Honey bee

text: To manage the mite, temperature treatments are possible, but also distorts wax of the honeycombs. Chemical fumigants, particularly CO, are also used.


title: Honey bee

text: "Varroa" mites are arguably the biggest threat to honey bees in the United States. These mites invade hives and reproduce by laying eggs on pupa. The hatching mites eat away at the pupa, causing deformities as well as spreading disease. If not detected and treated early on, the mite population may increase to such an extent that the hive will succumb to the diseases and deformities caused by the mites.


title: Honey bee

text: Honey is the complex substance made when bees ingest nectar, process it, and store the substance into honey combs. All living species of "Apis" have had their honey gathered by indigenous peoples for consumption. "A. mellifera" and "A. cerana" are the only species that have had their honey harvested for commercial purposes.


title: Honey bee

text: Worker bees of a certain age secrete beeswax from a series of exocrine glands on their abdomens. They use the wax to form the walls and caps of the comb. As with honey, beeswax is gathered by humans for various purposes such as candle making, waterproofing, soap and cosmetics manufacturing, pharmaceuticals, art, furniture polish and more.


title: Honey bee

text: Worker bees combine pollen, honey and glandular secretions and allow it to ferment in the comb to make bee bread. The fermentation process releases additional nutrients from the pollen and can produce antibiotics and fatty acids which inhibit spoilage. Bee bread is eaten by nurse bees (younger workers) which produce the protein-rich royal jelly needed by the queen and developing larvae in their hypopharyngeal glands.


title: Honey bee

text: In the hive, pollen is used as a protein source necessary during brood-rearing. In certain environments, excess pollen can be collected from the hives of "A. mellifera" and "A. cerana". The product is used as a health supplement. It has been used with moderate success as a source of pollen for hand pollination.


title: Honey bee

text: Bee brood – the eggs, larvae or pupae of honey bees – is nutritious and seen as a delicacy in countries such as Indonesia, Mexico, Thailand, and many African countries; it has been consumed since ancient times by the Chinese and Egyptians.


title: Honey bee

text: Adult wild honeybees are also consumed as a food in parts of China, including Yunnan. According to a worker at a Yunnan-based specialty restaurant, the bees are best served "deep-fried with salt and pepper", and they are "naturally sweet and tasty". Kellie Schmitt of "CNN" described the dish as one of "Shanghai's weirdest foods".


title: Honey bee

text: Propolis is a resinous mixture collected by honey bees from tree buds, sap flows or other botanical sources, which is used as a sealant for unwanted open spaces in the hive. Although propolis is alleged to have health benefits (tincture of Propolis is marketed as a cold and flu remedy), it may cause severe allergic reactions in some individuals. Propolis is also used in wood finishes, and gives a Stradivarius violin its unique red color.


title: Honey bee

text: Royal jelly is a honey bee secretion used to nourish the larvae. It is marketed for its alleged but unsupported claims of health benefits. On the other hand, it may cause severe allergic reactions in some individuals.


title: Honey bee

text: Honey bees have three castes: drones, workers, and queens. Drones are male, while workers and queens are female.


title: Honey bee

text: Drones are typically haploid, having only one set of chromosomes, and primarily exist for the purpose of reproduction. They are produced by the queen if she chooses not to fertilize an egg or by an unfertilized laying worker. There are rare instances of diploid drone larvae. This phenomenon usually arises when there are more than two generations of brother-sister mating. Sex determination in honey bees is initially due to a single locus, called the complementary sex determiner ("csd") gene. In developing bees, if the conditions are that the individual is heterozygous for the "csd" gene, they will develop into females. If the conditions are so that the individual is hemizygous or homozygous for the "csd" gene, they will develop into males. The instances where the individual is homozygous at this gene are the instances of diploid males. Drones take 24 days to develop, and may be produced from summer through to autumn, numbering as many as 500 per hive. They are expelled from the hive during the winter months when the hive's primary focus is warmth and food conservation. Drones have large eyes used to locate queens during mating flights. They do not defend the hive or kill intruders, and do not have a stinger.


title: Honey bee

text: Workers have two sets of chromosomes. They are produced from an egg that the queen has selectively fertilized from stored sperm. Workers typically develop in 21 days. A typical colony may contain as many as 60,000 worker bees. Workers exhibit a wider range of behaviors than either queens or drones. Their duties change with age in the following order (beginning with cleaning out their own cell after eating through their capped brood cell): feed brood, receive nectar, clean hive, guard duty, and foraging. Some workers engage in other specialized behaviors, such as "undertaking" (removing corpses of their nestmates from inside the hive).


title: Honey bee

text: Workers have morphological specializations, including the pollen basket "(corbicula)", abdominal glands that produce beeswax, brood-feeding glands, and barbs on the sting. Under certain conditions (for example, if the colony becomes queenless), a worker may develop ovaries.


title: Honey bee

text: Worker honey bees perform different behavioural tasks that cause them to be exposed to different local environments. The gut microbial composition of workers varies according to the landscape and plant species they forage, such as differences in rapeseed crops, and with different hive tasks, such as nursing or food processing.


title: Honey bee

text: Queen honey bees are created when worker bees feed a single female larva an exclusive diet of a food called "royal jelly". Queens are produced in oversized cells and develop in only 16 days; they differ in physiology, morphology, and behavior from worker bees. In addition to the greater size of the queen, she has a functional set of ovaries, and a spermatheca, which stores and maintains sperm after she has mated. "Apis" queens practice polyandry, with one female mating with multiple males. The highest documented mating frequency for an "Apis" queen is in "Apis nigrocincta", where queens mate with an extremely high number of males with observed numbers of different matings ranging from 42 to 69 drones per queen. The sting of queens is not barbed like a worker's sting, and queens lack the glands that produce beeswax. Once mated, queens may lay up to 2,000 eggs per day. They produce a variety of pheromones that regulate behavior of workers, and helps swarms track the queen's location during the swarming.


title: Honey bee

text: When a fertile female worker produces drones, a conflict arises between her interests and those of the queen. The worker shares half her genes with the drone and one-quarter with her brothers, favouring her offspring over those of the queen. The queen shares half her genes with her sons and one-quarter with the sons of fertile female workers. This pits the worker against the queen and other workers, who try to maximize their reproductive fitness by rearing the offspring most related to them. This relationship leads to a phenomenon known as "worker policing". In these rare situations, other worker bees in the hive who are genetically more related to the queen's sons than those of the fertile workers will patrol the hive and remove worker-laid eggs. Another form of worker-based policing is aggression toward fertile females. Some studies have suggested a queen pheromone which may help workers distinguish worker- and queen-laid eggs, but others indicate egg viability as the key factor in eliciting the behavior. Worker policing is an example of forced altruism, where the benefits of worker reproduction are minimized and that of rearing the queen's offspring maximized.


title: Honey bee

text: In very rare instances workers subvert the policing mechanisms of the hive, laying eggs which are removed at a lower rate by other workers; this is known as anarchic syndrome. Anarchic workers can activate their ovaries at a higher rate and contribute a greater proportion of males to the hive. Although an increase in the number of drones would decrease the overall productivity of the hive, the reproductive fitness of the drones' mother would increase. Anarchic syndrome is an example of selection working in opposite directions at the individual and group levels for the stability of the hive.


title: Honey bee

text: Under ordinary circumstances the death (or removal) of a queen increases reproduction in workers, and a significant proportion of workers will have active ovaries in the absence of a queen. The workers of the hive produce a last batch of drones before the hive eventually collapses. Although during this period worker policing is usually absent, in certain groups of bees it continues.


title: Honey bee

text: According to the strategy of kin selection, worker policing is not favored if a queen does not mate multiple times. Workers would be related by three-quarters of their genes, and the difference in relationship between sons of the queen and those of the other workers would decrease. The benefit of policing is negated, and policing is less favored. Experiments confirming this hypothesis have shown a correlation between higher mating rates and increased rates of worker policing in many species of social hymenoptera.


title: Honey bee

text: All honey bees live in colonies where the workers sting intruders as a form of defense, and alarmed bees release a pheromone that stimulates the attack response in other bees. The different species of honey bees are distinguished from all other bee species by the possession of small barbs on the sting, but these barbs are found only in the worker bees.


title: Honey bee

text: The sting apparatus, including the barbs, may have evolved specifically in response to predation by vertebrates, as the barbs do not usually function (and the sting apparatus does not detach) unless the sting is embedded in fleshy tissue. While the sting can also penetrate the membranes between joints in the exoskeleton of other insects (and is used in fights between queens), in the case of "Apis cerana japonica", defense against larger insects such as predatory wasps (e.g. Asian giant hornet) is usually performed by surrounding the intruder with a mass of defending worker bees, which vibrate their muscles vigorously to raise the temperature of the intruder to a lethal level ("balling"). Previously, heat alone was thought to be responsible for killing intruding wasps, but recent experiments have demonstrated the increased temperature in combination with increased carbon dioxide levels within the ball produce the lethal effect. This phenomenon is also used to kill a queen perceived as intruding or defective, an action known to beekeepers as 'balling the queen', named for the ball of bees formed.


title: Honey bee

text: Defense can vary based on the habitat of the bee. In the case of those honey bee species with open combs (e.g., "A. dorsata"), would-be predators are given a warning signal that takes the form of a "wave" that spreads as a ripple across a layer of bees densely packed on the surface of the comb when a threat is perceived, and consists of bees momentarily arching their bodies and flicking their wings. In cavity dwelling species such as "Apis cerana", "Apis mellifera", and "Apis nigrocincta", entrances to these cavities are guarded and checked for intruders in incoming traffic. Another act of defense against nest invaders, particularly wasps, is "body shaking," a violent and pendulum like swaying of the abdomen, performed by worker bees.


title: Honey bee

text: A 2020 study of "Apis cerana" in Vietnam found that they use feces and even human urine to defend their hives against raids by hornets ("Vespa soror"), a strategy not replicated by their European and North American counterparts, though collection and use of feces in nest construction is well-known in stingless bees.


title: Honey bee

text: The stings of honey bees are barbed and therefore embed themselves into the sting site, and the sting apparatus has its own musculature and ganglion which keep delivering venom even after detachment. The gland which produces the alarm pheromone is also associated with the sting apparatus. The embedded stinger continues to emit additional alarm pheromone after it has torn loose; other defensive workers are thereby attracted to the sting site. The worker dies after the sting becomes lodged and is subsequently torn loose from the bee's abdomen. The honey bee's venom, known as apitoxin, carries several active components, the most abundant of which is melittin, and the most biologically active are enzymes, particularly phospholipase A2.


title: Honey bee

text: Honey bee venom is under laboratory and clinical research for its potential properties and uses in reducing risks for adverse events from bee venom therapy, rheumatoid arthritis, and use as an immunotherapy for protection against allergies from insect stings. Bee venom products are marketed in many countries, but, as of 2018, there are no approved clinical uses for these products which carry various warnings for potential allergic reactions.


title: Honey bee

text: With an increased number of honey bees in a specific area due to beekeeping, Western honey bees (as an invasive species) and native wild bees often have to compete for the limited habitat and food sources available, and Western honey bees may become defensive in response to the seasonal arrival of competition from other colonies, particularly Africanized bees which may be on the offence and defence year round due to their tropical origin.


title: Honey bee

text: Honey bees are known to communicate through many different chemicals and odors, as is common in insects. They also rely on a sophisticated dance language that conveys information about the distance and direction to a specific location (typically a nutritional source, e.g., flowers or water). The dance language is also used during the process of reproductive fission, or swarming, when scouts communicate the location and quality of nesting sites.


title: Honey bee

text: The details of the signalling being used vary from species to species; for example, the two smallest species, "Apis andreniformis" and "A. florea", dance on the upper surface of the comb, which is horizontal (not vertical, as in other species), and worker bees orient the dance in the actual compass direction of the resource to which they are recruiting.


title: Honey bee

text: Carniolan honey bees ("Apis mellifera carnica") use their antennae asymmetrically for social interactions, with a strong lateral preference to use their right antennae.


title: Honey bee

text: There has been speculation as to honey bee consciousness. While honey bees lack the parts of the brain that a human being uses for consciousness like the cerebral cortex or even the cerebrum itself, when those parts of a human brain are damaged, the midbrain seems able to provide a small amount of consciousness. Honey bees have a tiny structure that appears similar to a human midbrain, so if it functions the same way they may possibly be able to achieve a small amount of simple awareness of their bodies.


title: Honey bee

text: The bee was used as a symbol of government by Emperor Napoleon I of France. Both the Hindu "Atharva Veda" and the ancient Greeks associated lips anointed with honey with the gift of eloquence and even of prescience. The priestess at Delphi was the "Delphic Bee".


title: Honey bee

text: The "Quran" has a Sura (chapter) titled "The Bee". It is named after honey bees, and contains a comparison of the industry and adaptability of honey bees to the industry of man.


title: Honey bee

text: In ancient Egyptian mythology, honey bees were believed to be born from the tears of the Sun God, Ra.


title: Honey bee

text: A community of honey bees has often been employed by political theorists as a model of human society, from Aristotle and Plato to Virgil. Honey bees, signifying immortality and resurrection, were royal emblems of the Merovingians. The state of Utah is called the "Beehive State", the state emblem is the beehive, the state insect is the honey bee, and a beehive and the word "industry" appear on both the state flag and seal.

title: Tehran (TV series)

text: Protagonist Tamar Rabinyan, a young Jewish woman born in Iran but raised in Israel, is a Mossad agent and computer hacker on an undercover mission in the Iranian capital to disable a nuclear reactor. Her objective is neutralizing Iranian air defenses so that the Israeli Air Force can bomb a nuclear plant and prevent Iran from obtaining an atomic bomb. When she arrives in Iran she switches identities with Zhila Gorbanifar, a Muslim employee of the local electric company. In Zhila's place she enters the electric company station and connects to the computer network. Then she tries to cut electric power to the Iranian radar system, in order to facilitate an ongoing Israeli Air Force attack. Her mission fails because her boss, who thinks she is Zhila, tries to rape her and is killed in a fight that ensues. After escaping, Tamar has to go into hiding. Being born in Iran and having moved to Israel when she was six, Tamar now discovers her local roots, goes to see her aunt, and befriends Iranian pro-democracy activists. Meanwhile, she is hunted by Faraz Kamali, head of investigations of the Revolutionary Guards.


title: Tehran (TV series)

text: Prior to being smuggled out of Iran to start a new life in Canada, Tamar accepts a mission to rescue one of the Israeli pilots captured after the reactor mission. At the hospital where the pilot is being held, she encounters Marjan Montazami, a psychotherapist and local agent for Mossad, who aids in her escape. Tamar's aunt is executed for assisting her, and a devastated Tamar agrees to stay in Tehran with Milad to undertake a new mission: the assassination of Qasem Mohammadi who has been promoted to head of the Revolutionary Guard. Tamar works to gain access to Mohammadi by getting close to his son, Peyman. Faraz Kamali continues his relentless pursuit of Tamar, but finds himself compromised as Marjan begins working as a psychotherapist for his wife following her abduction and release by Mossad. In spite of Faraz's reluctant assistance, Tamar's attempt to poison Mohammadi fails, as does an attempt to kill him with a booby-trapped phone. Mossad head Yulia Magen calls off the mission, but Tamar and Milad try to take control of Mohammadi's sports car as he races against his son, which only results in Peyman's death. Marjan is poisoned by Nahid, Faraz's wife. Tamar manages to kill Mohammadi with the explosive mobile phone. Milad is killed by a car bomb planted by the Mossad in the escape car, leaving Tamar alone and trapped in Iran with no-one to trust.

title: Even-toed ungulate

text: The even-toed ungulates (Artiodactyla , ) are ungulates—hoofed animals—which bear weight equally on two (an even number) of their five toes: the third and fourth. The other three toes are either present, absent, vestigial, or pointing posteriorly. By contrast, odd-toed ungulates bear weight on an odd number of the five toes. Another difference between the two is that many other even-toed ungulates (with the exception of Suina) digest plant cellulose in one or more stomach chambers rather than in their intestine as the odd-toed ungulates do.


title: Even-toed ungulate

text: Cetaceans (whales, dolphins, and porpoises) evolved from even-toed ungulates, and are therefore often classified under the same taxonomic branch because a species cannot outgrow its evolutionary ancestry; some modern taxonomists combine the two under the name Cetartiodactyla , while others opt to include cetaceans in the already-existing Artiodactyla.


title: Even-toed ungulate

text: The roughly 270 land-based even-toed ungulate species include pigs, peccaries, hippopotamuses, antelopes, deer, giraffes, camels, llamas, alpacas, sheep, goats, and cattle. Many are herbivores, but suids are omnivorous, while cetaceans are almost exclusively carnivorous. Many of these are of great dietary, economic, and cultural importance to humans.


title: Even-toed ungulate

text: The oldest fossils of even-toed ungulates date back to the early Eocene (about 53 million years ago). Since these findings almost simultaneously appeared in Europe, Asia, and North America, it is very difficult to accurately determine the origin of artiodactyls. The fossils are classified as belonging to the family Dichobunidae; their best-known and best-preserved member is "Diacodexis". These were small animals, some as small as a hare, with a slim build, lanky legs, and a long tail. Their hind legs were much longer than their front legs. The early to middle Eocene saw the emergence of the ancestors of most of today's mammals.


title: Even-toed ungulate

text: Two formerly widespread, but now extinct, families of even-toed ungulates were Entelodontidae and Anthracotheriidae. Entelodonts existed from the middle Eocene to the early Miocene in Eurasia and North America. They had a stocky body with short legs and a massive head, which was characterized by two humps on the lower jaw bone. Anthracotheres had a large, porcine (pig-like) build, with short legs and an elongated muzzle. This group appeared in the middle Eocene up until the Pliocene, and spread throughout Eurasia, Africa, and North America. Anthracotheres are thought to be the ancestors of hippos, and, likewise, probably led a similar aquatic lifestyle. Hippopotamuses appeared in the late Miocene and occupied Africa and Asia—they never got to the Americas.


title: Even-toed ungulate

text: The camels (Tylopoda) were, during large parts of the Cenozoic, limited to North America; early forms like Cainotheriidae occupied Europe. Among the North American camels were groups like the stocky, short-legged Merycoidodontidae. They first appeared in the late Eocene and developed a great diversity of species in North America. Only in the late Miocene or early Pliocene did they migrate from North America into Eurasia. The North American varieties became extinct around 10,000 years ago.


title: Even-toed ungulate

text: Suina (including pigs) have been around since the Eocene. In the late Eocene or the Oligocene, two families stayed in Eurasia and Africa; the peccaries, which became extinct in the Old World, exist today only in the Americas.


title: Even-toed ungulate

text: South America was settled by even-toed ungulates only in the Pliocene, after the land bridge at the Isthmus of Panama formed some three million years ago. With only the peccaries, lamoids (or llamas), and various species of capreoline deer, South America has than other continents, except Australia, which has no native species.


title: Even-toed ungulate

text: The classification of artiodactyls was hotly debated because the ocean-dwelling cetaceans evolved from the land-dwelling even-toed ungulates. Some semiaquatic even-toed ungulates (hippopotamuses) are more closely related to the ocean-dwelling cetaceans than to the other even-toed ungulates.


title: Even-toed ungulate

text: This makes the Artiodactyla as traditionally defined a paraphyletic taxon, since it includes animals descended from a common ancestor, but does not include all of its descendants. Phylogenetic classification only recognizes monophyletic taxa; that is, groups that descend from a common ancestor and include all of its descendants. To address this problem, the traditional order Artiodactyla and infraorder Cetacea are sometimes subsumed into the more inclusive Cetartiodactyla taxon. An alternative approach is to include both land-dwelling even-toed ungulates and ocean-dwelling cetaceans in a revised Artiodactyla taxon.


title: Even-toed ungulate

text: In the 1990s, biological systematics used not only morphology and fossils to classify organisms, but also molecular biology. Molecular biology involves sequencing an organism's DNA and RNA and comparing the sequence with that of other living beings—the more similar they are, the more closely they are related. Comparison of even-toed ungulate and cetaceans genetic material has shown that the closest living relatives of whales and hippopotamuses is the paraphyletic group Artiodactyla.


title: Even-toed ungulate

text: Dan Graur and Desmond Higgins were among the first to come to this conclusion, and included a paper published in 1994. However, they did not recognize hippopotamuses and classified the ruminants as the sister group of cetaceans. Subsequent studies established the close relationship between hippopotamuses and cetaceans; these studies were based on casein genes, SINEs, fibrinogen sequences, cytochrome and rRNA sequences, IRBP (and vWF) gene sequences, adrenergic receptors, and apolipoproteins.


title: Even-toed ungulate

text: In 2001, the fossil limbs of a "Pakicetus" (amphibioid cetacean the size of a wolf) and "Ichthyolestes" (an early whale the size of a fox) were found in Pakistan. They were both archaeocetes ("ancient whales") from about 48 million years ago (in the Eocene). These findings showed that archaeocetes were more terrestrial than previously thought, and that the special construction of the talus (ankle bone) with a double-rolled joint surface, previously thought to be unique to even-toed ungulates, were also in early cetaceans. The mesonychids, another type of ungulate, did not show this special construction of the talus, and thus was concluded to not have the same ancestors as cetaceans.


title: Even-toed ungulate

text: The oldest cetaceans date back to the early Eocene (53 million years ago), whereas the oldest known hippopotamus dates back only to the Miocene (15 million years ago). The hippopotamids are descended from the anthracotheres, a family of semiaquatic and terrestrial artiodactyls that appeared in the late Eocene, and are thought to have resembled small- or narrow-headed hippos. Research is therefore focused on anthracotheres (family Anthracotheriidae); one dating from the Eocene to Miocene was declared to be "hippo-like" upon discovery in the 19th century. A study from 2005 showed that the anthracotheres and hippopotamuses have very similar skulls, but differed in the adaptations of their teeth. It was nevertheless believed that cetaceans and anthracothereres descended from a common ancestor, and that hippopotamuses developed from anthracotheres. A study published in 2015 was able to confirm this, but also revealed that hippopotamuses were derived from older anthracotherians. The newly introduced genus "Epirigenys" from eastern Africa is thus the sister group of hippos.


title: Even-toed ungulate

text: Linnaeus postulated a close relationship between camels and ruminants as early as the mid-1700s. Henri de Blainville recognized the similar anatomy of the limbs of pigs and hippos, and British zoologist Richard Owen coined the term "even-toed ungulates" and the scientific name "Artiodactyla" in 1848.


title: Even-toed ungulate

text: Internal morphology (mainly the stomach and the molars) were used for classification. Suines (including pigs) and hippopotamuses have molars with well-developed roots and a simple stomach that digests food. Thus, they were grouped together as non-ruminants (Porcine). All other even-toed ungulates have molars with a selenodont construction (crescent-shaped cusps) and have the ability to ruminate, which requires regurgitating food and re-chewing it. Differences in stomach construction indicated that rumination evolved independently between tylopods and ruminants; therefore, tylopods were excluded from Ruminantia.


title: Even-toed ungulate

text: Modern cetaceans are highly adapted sea creatures which, morphologically, have little in common with land mammals; they are similar to other marine mammals, such as seals and sea cows, due to convergent evolution. However, they evolved from originally terrestrial mammals. The most likely ancestors were long thought to be mesonychids—large, carnivorous animals from the early Cenozoic (Paleocene and Eocene), which had hooves instead of claws on their feet. Their molars were adapted to a carnivorous diet, resembling the teeth in modern toothed whales, and, unlike other mammals, have a uniform construction.


title: Even-toed ungulate

text: Molecular findings and morphological indications suggest that artiodactyls as traditionally defined are paraphyletic with respect to cetaceans. Cetaceans are deeply nested within the former; the two groups together form a monophyletic taxon, for which the name Cetartiodactyla is sometimes used. Modern nomenclature divides Artiodactyla (or Cetartiodactyla) in four subordinate taxa: camelids (Tylopoda), pigs and peccaries (Suina), ruminants (Ruminantia), and hippos plus whales (Whippomorpha).


title: Even-toed ungulate

text: Although deer, musk deer, and pronghorns have traditionally been summarized as cervids (Cervioidea), molecular studies provide different—and inconsistent—results, so the question of phylogenetic systematics of infraorder Pecora (the horned ruminants) for the time being, cannot be answered.


title: Even-toed ungulate

text: Artiodactyls are generally quadrupeds. Two major body types are known: Suinids and hippopotamuses are characterized by a stocky body, short legs, and a large head; camels and ruminants, though, have a more slender build and lanky legs. Size varies considerably; the smallest member, the mouse deer, often reaches a body length of only and a weight of . The largest member, the hippopotamus, can grow up to in length and weigh , and the giraffe can grow to be tall and in body length. All even-toed ungulates display some form of sexual dimorphism: the males are consistently larger and heavier than the females. In deer, only the males boast antlers, and the horns of bovines are usually small or not present in females. Male Indian antelopes have a much darker coat than females.


title: Even-toed ungulate

text: Almost all even-toed ungulates have fur, with an exception being the nearly hairless hippopotamus. Fur varies in length and coloration depending on the habitat. Species in cooler regions can shed their coat. Camouflaged coats come in colors of yellow, gray, brown, or black tones.


title: Even-toed ungulate

text: Even-toed ungulates bear their name because they have an even number of toes (two or four)—in some peccaries, the hind legs have a reduction in the number of toes to three. The central axis of the leg is between the third and fourth toe. The first toe is missing in modern artiodactyls, and can only be found in now-extinct genera. The second and fifth toes are adapted differently between species:


title: Even-toed ungulate

text: When camels have only two toes present, the claws are transformed into nails (while both are made of keratin, claws are curved and pointed while nails are flat and dull). These claws consist of three parts: the plate (top and sides), the sole (bottom), and the bale (rear). In general, the claws of the forelegs are wider and blunter than those of the hind legs, and they are farther apart. Aside from camels, all even-toed ungulates put just the tip of the foremost phalanx on the ground.


title: Even-toed ungulate

text: In even-toed ungulates, the bones of the stylopodium (upper arm or thigh bone) and zygopodiums (tibia and fibula) are usually elongated. The muscles of the limbs are predominantly localized, which ensures that artiodactyls often have very slender legs. A clavicle is never present, and the scapula is very agile and swings back and forth for added mobility when running. The special construction of the legs causes the legs to be unable to rotate, which allows for greater stability when running at high speeds. In addition, many smaller artiodactyls have a very flexible body, contributing to their speed by increasing their stride length.


title: Even-toed ungulate

text: Many even-toed ungulates have a relatively large head. The skull is elongated and rather narrow; the frontal bone is enlarged near the back and displaces the parietal bone, which forms only part of the side of the cranium (especially in ruminants).


title: Even-toed ungulate

text: Four families of even-toed ungulates have cranial appendages. These Pecora (with the exception of the musk deer), have one of four types of cranial appendages: true horns, antlers, ossicones, or pronghorns.


title: Even-toed ungulate

text: "True horns" have a bone core that is covered in a permanent sheath of keratin, and are found only in the bovids. "Antlers" are bony structures that are shed and replaced each year; they are found in deer (members of the family Cervidae). They grow from a permanent outgrowth of the frontal bone called the pedicle and can be branched, as in the white-tailed deer ("Odocoileus virginianus"), or palmate, as in the moose ("Alces alces"). "Ossicones" are permanent bone structures that fuse to the frontal or parietal bones during an animal's life and are found only in the Giraffidae. "Pronghorns", while similar to horns in that they have keratinous sheaths covering permanent bone cores, are deciduous.


title: Even-toed ungulate

text: All these cranial appendages can serve for posturing, battling for mating privilege, and for defense. In almost all cases, they are sexually dimorphic, and often found only on the males. One exception is the species "Rangifer tarandus", known as reindeer in Europe or caribou in North America, where both sexes can grow antlers yearly, though the females' antlers are typically smaller and not always present.


title: Even-toed ungulate

text: There are two trends in terms of teeth within Artiodactyla. The Suina and hippopotamuses have a relatively large number of teeth (with some pigs having 44); their dentition is more adapted to a squeezing mastication, which is characteristic of omnivores. Camels and ruminants have fewer teeth; there is often a yawning diastema, a designated gap in the teeth where the molars are aligned for crushing plant matter.


title: Even-toed ungulate

text: The incisors are often reduced in ruminants, and are completely absent in the upper jaw. The canines are enlarged and tusk-like in the Suina, and are used for digging in the ground and for defense. In ruminants, the males' upper canines are enlarged and used as a weapon in certain species (mouse deer, musk deer, water deer); species with frontal weapons are usually missing the upper canines. The lower canines of ruminants resemble the incisors, so that these animals have eight uniform teeth in the frontal part of the lower jaw.


title: Even-toed ungulate

text: The molars of porcine have only a few bumps. In contrast, the camels and ruminants have bumps that are crescent-shaped cusps (selenodont).


title: Even-toed ungulate

text: Artiodactyls have a well-developed sense of smell and sense of hearing. Unlike many other mammals, they have a poor sense of sight—moving objects are much easier to see than stationary ones. Similar to many other prey animals, their eyes are on the sides of the head, giving them an almost panoramic view.


title: Even-toed ungulate

text: The ruminants (Ruminantia and Tylopoda) ruminate their food—they regurgitate and re-chew it. Ruminants' mouths often have additional salivary glands, and the oral mucosa is often heavily calloused to avoid injury from hard plant parts and to allow easier transport of roughly chewed food. Their stomachs are divided into three to four sections: the rumen, the reticulum, the omasum, and the abomasum. After the food is ingested, it is mixed with saliva in the rumen and reticulum and separates into layers of solid versus liquid material. The solids lump together to form a bolus (also known as the cud); this is regurgitated by reticular contractions while the glottis is closed. When the bolus enters the mouth, the fluid is squeezed out with the tongue and re-swallowed. The bolus is chewed slowly to completely mix it with saliva and to break it down. Ingested food passes to the "fermentation chamber" (rumen and reticulum), where it is kept in continual motion by rhythmic contractions. Cellulytic microbes (bacteria, protozoa, and fungi) produce cellulase, which is needed to break down the cellulose found in plant material. This form of digestion has two advantages: plants that are indigestible to other species can be digested and used, and the duration of the actual food consumption shortened; the animal spends only a short time out in the open with his head to the ground—rumination can take place later, in a sheltered area.


title: Even-toed ungulate

text: Tylopoda (camels, llamas, and alpacas) and chevrotains have three-chambered stomachs, while the rest of Ruminantia have four-chambered stomachs. The handicap of a heavy digestive system has increased selective pressure towards limbs that allow the animal to quickly escape predators. Most species within Suina have a simple two-chambered stomach that allows an omnivorous diet. The babirusa, however, is an herbivore, and has extra maxillary teeth to allow for proper mastication of plant material. Most of the fermentation occurs with the help of cellulolytic microorganisms within the caecum of the large intestine. Peccaries have a complex stomach that contains four compartments. Their fore stomach has fermentation carried out by microbes and has high levels of volatile fatty acid; it has been proposed that their complex fore stomach is a means to slow digestive passage and increase digestive efficiency. Hippopotamuses have three-chambered stomachs and do not ruminate. They consume around of grass and other plant matter each night. They may cover distances up to to obtain food, which they digest with the help of microbes that produce cellulase. Their closest living relatives, the whales, are obligate carnivores.


title: Even-toed ungulate

text: Unlike other even-toed ungulates, pigs have a simple sack-shaped stomach. Some artiodactyla, such as white-tailed deer, lack a gall bladder.


title: Even-toed ungulate

text: The penises of even-toed ungulates have an S-shape at rest and lie in a pocket under the skin on the belly. The corpora cavernosa are only slightly developed; and an erection mainly causes this curvature to extend, which leads to an extension, but not a thickening, of the penis. Cetaceans have similar penises. In some even-toed ungulates, the penis contains a structure called the "urethral process."


title: Even-toed ungulate

text: The testicles are located in the scrotum and thus outside the abdominal cavity. The ovaries of many females descend—as testicles descend of many male mammals—and are close to the pelvic inlet at the level of the fourth lumbar vertebra. The uterus has two horns (uterus bicornis).


title: Even-toed ungulate

text: The number of mammary glands is variable and correlates, as in all mammals, with litter size. Pigs, which have the largest litter size of all even-toed ungulates, have two rows of teats lined from the armpit to the groin area. In most cases, however, even-toed ungulates have only one or two pairs of teats. In some species these form an udder in the groin region.


title: Even-toed ungulate

text: Secretory glands in the skin are present in virtually all species and can be located in different places, such as in the eyes, behind the horns, the neck, or back, on the feet, or in the anal region.


title: Even-toed ungulate

text: Artiodactyls are native to almost all parts of the world, with the exception of Oceania and Antarctica. Humans have introduced different artiodactyls worldwide as hunting animals. Artiodactyls inhabit almost every habitat, from tropical rainforests and steppes to deserts and high mountain regions. The greatest biodiversity prevails in open habitats such as grasslands and open forests.


title: Even-toed ungulate

text: The social behavior of even-toed ungulates varies from species to species. Generally, there is a tendency to merge into larger groups, but some live alone or in pairs. Species living in groups often have a hierarchy, both among males and females. Some species also live in harem groups, with one male, several females, and their common offspring. In other species, the females and juveniles stay together, while males are solitary or live in bachelor groups and seek out females only during mating season.


title: Even-toed ungulate

text: Many artiodactyls are territorial and mark their territory, for example, with glandular secretions or urine. In addition to year-round sedentary species, there are animals that migrate seasonally.


title: Even-toed ungulate

text: There are diurnal, crepuscular, and nocturnal artiodactyls. Some species' pattern of wakefulness varies with season or habitat.


title: Even-toed ungulate

text: Generally, even-toed ungulates tend to have long gestation periods, smaller litter sizes, and more highly developed newborns. As with many other mammals, species in temperate or polar regions have a fixed mating season, while those in tropical areas breed year-round. They carry out polygynous mating behavior, meaning a male mates with several females and suppresses all competition.


title: Even-toed ungulate

text: The length of the gestation period varies from four to five months for porcine, deer, and musk deer; six to ten months for hippos, deer, and bovines; ten to thirteen months with camels; and fourteen to fifteen months with giraffes. Most deliver one or two babies, but some pigs can deliver up to ten.


title: Even-toed ungulate

text: The newborns are precocial (born relatively mature) and come with open eyes and are hairy (with the exception of the hairless hippos). Juvenile deer and pigs have striped or spotted coats; the pattern disappears as they grow older. The juveniles of some species spend their first weeks with their mother in a safe location, where others may be running and following the herd within a few hours or days.


title: Even-toed ungulate

text: The life expectancy is typically twenty to thirty years; as in many mammals, smaller species often have a shorter lifespan than larger species. The artiodactyls with the longest lifespans are the hippos, cows, and camels, which can live 40 to 50 years.


title: Even-toed ungulate

text: Artiodactyls have different natural predators depending on their size and habitat. There are several carnivores that prey on them, including large cats (e.g., lions) and bears. Other predators are crocodiles, wolves and dogs, large raptors, and for small species and young animals, large snakes. For cetaceans, possible predators include sharks, polar bears, and other cetaceans; in the latter is the orca, the top predator of the oceans.


title: Even-toed ungulate

text: Parasites include nematodes, botflies, fleas, lice, or flukes, but they have debilitating effects only when the infestation is severe.


title: Even-toed ungulate

text: Artiodactyls have been hunted by primitive humans for various reasons: for meat or fur, as well as to use their bones and teeth as weapons or tools. Their domestication began around 8000 BCE. To date, humans have domesticated goats, sheep, cattle, camels, llamas, alpacas, and pigs. Initially, livestock was used primarily for food, but they began being used for work activities around 3000 BCE. Clear evidence exists of antelope being used for food 2 million years ago in the Olduvai Gorge, part of the Great Rift Valley. Cro-Magnons relied heavily on reindeer for food, skins, tools, and weapons; with dropping temperatures and increased reindeer numbers at the end of the Pleistocene, they became the prey of choice. Reindeer remains accounted for 94% of bones and teeth found in a cave above the river Céou that was inhabited around 12,500 years ago.


title: Even-toed ungulate

text: Today, artiodactyls are kept primarily for their meat, milk, and wool, fur, or hide for clothing. Domestic cattle, the water buffalo, the yak, and camels are used for work, as rides, or as pack animals.


title: Even-toed ungulate

text: The endangerment level of each even-toed ungulate is different. Some species are synanthropic (such as the wild boar) and have spread into areas that they are not indigenous to, either having been brought as farm animals or having run away as people's pets. Some artiodactyls also benefit from the fact that their predators (e.g. the Tasmanian tiger) were severely decimated by ranchers, who saw them as competition.


title: Even-toed ungulate

text: Conversely, many artiodactyls have declined significantly in numbers, and some have even gone extinct, largely due to over-hunting, and, more recently, habitat destruction. Extinct species include several gazelles, the aurochs, the Malagasy hippopotamus, the bluebuck, and Schomburgk's deer. Two species, the Scimitar-horned oryx and Père David's deer, are extinct in the wild. Fourteen species are considered critically endangered, including the addax, the kouprey, the Bactrian camel, Przewalski's gazelle, the saiga, and the pygmy hog. Twenty-four species are considered endangered.


title: Song dynasty

text: The Song dynasty (; ; 960–1279) was an imperial dynasty of China that began in 960 and lasted until 1279. The dynasty was founded by Emperor Taizu of Song following his usurpation of the throne of the Later Zhou. The Song conquered the rest of the Ten Kingdoms, ending the Five Dynasties and Ten Kingdoms period. The Song often came into conflict with the contemporaneous Liao, Western Xia and Jin dynasties in northern China. After retreating to southern China, the Song was eventually conquered by the Mongol-led Yuan dynasty.


title: Song dynasty

text: The dynasty is divided into two periods: Northern Song and Southern Song. During the Northern Song (; 960–1127), the capital was in the northern city of Bianjing (now Kaifeng) and the dynasty controlled most of what is now Eastern China. The Southern Song (; 1127–1279) refers to the period after the Song lost control of its northern half to the Jurchen-led Jin dynasty in the Jin–Song Wars. At that time, the Song court retreated south of the Yangtze and established its capital at Lin'an (now Hangzhou). Although the Song dynasty had lost control of the traditional Chinese heartlands around the Yellow River, the Southern Song Empire contained a large population and productive agricultural land, sustaining a robust economy. In 1234, the Jin dynasty was conquered by the Mongols, who took control of northern China, maintaining uneasy relations with the Southern Song. Möngke Khan, the fourth Great Khan of the Mongol Empire, died in 1259 while besieging the mountain castle Diaoyucheng, Chongqing. His younger brother Kublai Khan was proclaimed the new Great Khan and in 1271 founded the Yuan dynasty. After two decades of sporadic warfare, Kublai Khan's armies conquered the Song dynasty in 1279 after defeating the Southern Song in the Battle of Yamen, and reunited China under the Yuan dynasty.


title: Song dynasty

text: Technology, science, philosophy, mathematics, and engineering flourished during the Song era. The Song dynasty was the first in world history to issue banknotes or true paper money and the first Chinese government to establish a permanent standing navy. This dynasty saw the first recorded chemical formula of gunpowder, the invention of gunpowder weapons such as fire arrows, bombs, and the fire lance. It also saw the first discernment of true north using a compass, first recorded description of the pound lock, and improved designs of astronomical clocks. Economically, the Song dynasty was unparalleled with a gross domestic product three times larger than that of Europe during the 12th century. China's population doubled in size between the 10th and 11th centuries. This growth was made possible by expanded rice cultivation, use of early-ripening rice from Southeast and South Asia, and production of widespread food surpluses. The Northern Song census recorded 20 million households, double of the Han and Tang dynasties. It is estimated that the Northern Song had a population of 90 million people, and 200 million by the time of the Ming dynasty. This dramatic increase of population fomented an economic revolution in pre-modern China.


title: Song dynasty

text: The expansion of the population, growth of cities, and emergence of a national economy led to the gradual withdrawal of the central government from direct involvement in economic affairs. The lower gentry assumed a larger role in local administration and affairs. Social life during the Song was vibrant. Citizens gathered to view and trade precious artworks, the populace intermingled at public festivals and private clubs, and cities had lively entertainment quarters. The spread of literature and knowledge was enhanced by the rapid expansion of woodblock printing and the 11th-century invention of movable-type printing. Philosophers such as Cheng Yi and Zhu Xi reinvigorated Confucianism with new commentary, infused with Buddhist ideals, and emphasized a new organization of classic texts that established the doctrine of Neo-Confucianism. Although civil service examinations had existed since the Sui dynasty, they became much more prominent in the Song period. Officials gaining power through imperial examination led to a shift from a military-aristocratic elite to a scholar-bureaucratic elite.


title: Song dynasty

text: After usurping the throne of the Later Zhou dynasty, Emperor Taizu of Song ( 960–976) spent sixteen years conquering the rest of China, reuniting much of the territory that had once belonged to the Han and Tang empires and ending the upheaval of the Five Dynasties and Ten Kingdoms period. In Kaifeng, he established a strong central government over the empire. The establishment of this capital marked the start of the Northern Song period. He ensured administrative stability by promoting the civil service examination system of drafting state bureaucrats by skill and merit (instead of aristocratic or military position) and promoted projects that ensured efficiency in communication throughout the empire. In one such project, cartographers created detailed maps of each province and city that were then collected in a large atlas. Emperor Taizu also promoted groundbreaking scientific and technological innovations by supporting works like the astronomical clock tower designed and built by the engineer Zhang Sixun.


title: Song dynasty

text: The Song court maintained diplomatic relations with Chola India, the Fatimid Caliphate of Egypt, Srivijaya, the Kara-Khanid Khanate in Central Asia, the Goryeo kingdom in Korea, and other countries that were also trade partners with Japan. Chinese records even mention an embassy from the ruler of "Fu lin" (拂菻, i.e. the Byzantine Empire), Michael VII Doukas, and its arrival in 1081. However, China's closest neighbouring states had the greatest impact on its domestic and foreign policy. From its inception under Taizu, the Song dynasty alternated between warfare and diplomacy with the ethnic Khitans of the Liao dynasty in the northeast and with the Tanguts of the Western Xia in the northwest. The Song dynasty used military force in an attempt to quell the Liao dynasty and to recapture the Sixteen Prefectures, a territory under Khitan control since 938 that was traditionally considered to be part of China proper (Most parts of today's Beijing and Tianjin). Song forces were repulsed by the Liao forces, who engaged in aggressive yearly campaigns into Northern Song territory until 1005, when the signing of the Shanyuan Treaty ended these northern border clashes. The Song were forced to provide tribute to the Khitans, although this did little damage to the Song economy since the Khitans were economically dependent upon importing massive amounts of goods from the Song. More significantly, the Song state recognized the Liao state as its diplomatic equal. The Song created an extensive defensive forest along the Song-Liao border to thwart potential Khitan cavalry attacks.


title: Song dynasty

text: The Song dynasty managed to win several military victories over the Tanguts in the early 11th century, culminating in a campaign led by the polymath scientist, general, and statesman Shen Kuo (1031–1095). However, this campaign was ultimately a failure due to a rival military officer of Shen disobeying direct orders, and the territory gained from the Western Xia was eventually lost. The Song fought against the Vietnamese kingdom of Đại Việt twice, the first conflict in 981 and later a significant war from 1075 to 1077 over a border dispute and the Song's severing of commercial relations with Đại Việt. After the Vietnamese forces inflicted heavy damages in a raid on Guangxi, the Song commander Guo Kui (1022–1088) penetrated as far as Thăng Long (modern Hanoi). Heavy losses on both sides prompted the Vietnamese commander Thường Kiệt (1019–1105) to make peace overtures, allowing both sides to withdraw from the war effort; captured territories held by both Song and Vietnamese were mutually exchanged in 1082, along with prisoners of war.


title: Song dynasty

text: During the 11th century, political rivalries divided members of the court due to the ministers' differing approaches, opinions, and policies regarding the handling of the Song's complex society and thriving economy. The idealist Chancellor, Fan Zhongyan (989–1052), was the first to receive a heated political backlash when he attempted to institute the Qingli Reforms, which included measures such as improving the recruitment system of officials, increasing the salaries for minor officials, and establishing sponsorship programs to allow a wider range of people to be well educated and eligible for state service.


title: Song dynasty

text: After Fan was forced to step down from his office, Wang Anshi (1021–1086) became Chancellor of the imperial court. With the backing of Emperor Shenzong (1067–1085), Wang Anshi severely criticized the educational system and state bureaucracy. Seeking to resolve what he saw as state corruption and negligence, Wang implemented a series of reforms called the New Policies. These involved land value tax reform, the establishment of several government monopolies, the support of local militias, and the creation of higher standards for the Imperial examination to make it more practical for men skilled in statecraft to pass.


title: Song dynasty

text: The reforms created political factions in the court. Wang Anshi's "New Policies Group" ("Xin Fa"), also known as the "Reformers", were opposed by the ministers in the "Conservative" faction led by the historian and Chancellor Sima Guang (1019–1086). As one faction supplanted another in the majority position of the court ministers, it would demote rival officials and exile them to govern remote frontier regions of the empire. One of the prominent victims of the political rivalry, the famous poet and statesman Su Shi (1037–1101), was jailed and eventually exiled for criticizing Wang's reforms.


title: Song dynasty

text: The continual alternation between reform and conservatism had effectively weakened the dynasty. This decline can also be attributed to Cai Jing (1047–1126), who was appointed by Emperor Zhezong (1085–1100) and who remained in power until 1125. He revived the New Policies and pursued political opponents, tolerated corruption and encouraged Emperor Huizong (1100–1126) to neglect his duties to focus on artistic pursuits. Later, a peasant rebellion broke out in Zhejiang and Fujian, headed by Fang La in 1120. The rebellion may have been caused by an increasing tax burden, the concentration of landownership and oppressive government measures.


title: Song dynasty

text: While the central Song court remained politically divided and focused upon its internal affairs, alarming new events to the north in the Liao state finally came to its attention. The Jurchen, a subject tribe of the Liao, rebelled against them and formed their own state, the Jin dynasty (1115–1234). The Song official Tong Guan (1054–1126) advised Emperor Huizong to form an alliance with the Jurchens, and the joint military campaign under this Alliance Conducted at Sea toppled and completely conquered the Liao dynasty by 1125. During the joint attack, the Song's northern expedition army removed the defensive forest along the Song-Liao border.

text: However, the poor performance and military weakness of the Song army was observed by the Jurchens, who immediately broke the alliance, beginning the Jin–Song Wars of 1125 and 1127. Because of the removal of the previous defensive forest, the Jin army marched quickly across the North China Plain to Kaifeng. In the Jingkang Incident during the latter invasion, the Jurchens captured not only the capital, but the retired Emperor Huizong, his successor Emperor Qinzong, and most of the Imperial court.


title: Song dynasty

text: The remaining Song forces regrouped under the self-proclaimed Emperor Gaozong of Song (1127–1162) and withdrew south of the Yangtze to establish a new capital at Lin'an (modern Hangzhou). The Jurchen conquest of North China and shift of capitals from Kaifeng to Lin'an was the dividing line between the Northern and Southern Song dynasties.


title: Song dynasty

text: After their fall to the Jin, the Song lost control of North China. Now occupying what has been traditionally known as "China Proper," the Jin regarded themselves the rightful rulers of China. The Jin later chose earth as their dynastic element and yellow as their royal color. According to the theory of the Five Elements (wuxing), the earth element follows the fire, the dynastic element of the Song, in the sequence of elemental creation. Therefore, their ideological move showed that the Jin considered Song reign in China complete, with the Jin replacing the Song as the rightful rulers of China Proper.


title: Song dynasty

text: Although weakened and pushed south beyond the Huai River, the Southern Song found new ways to bolster its strong economy and defend itself against the Jin dynasty. It had able military officers such as Yue Fei and Han Shizhong. The government sponsored massive shipbuilding and harbor improvement projects, and the construction of beacons and seaport warehouses to support maritime trade abroad, including at the major international seaports, such as Quanzhou, Guangzhou, and Xiamen, that were sustaining China's commerce.


title: Song dynasty

text: To protect and support the multitude of ships sailing for maritime interests into the waters of the East China Sea and Yellow Sea (to Korea and Japan), Southeast Asia, the Indian Ocean, and the Red Sea, it was necessary to establish an official standing navy. The Song dynasty therefore established China's first permanent navy in 1132, with a headquarters at Dinghai. With a permanent navy, the Song were prepared to face the naval forces of the Jin on the Yangtze River in 1161, in the Battle of Tangdao and the Battle of Caishi. During these battles the Song navy employed swift paddle wheel driven naval vessels armed with traction trebuchet catapults aboard the decks that launched gunpowder bombs. Although the Jin forces commanded by Wanyan Liang (the Prince of Hailing) boasted 70,000 men on 600 warships, and the Song forces only 3,000 men on 120 warships, the Song dynasty forces were victorious in both battles due to the destructive power of the bombs and the rapid assaults by paddlewheel ships. The strength of the navy was heavily emphasized following these victories. A century after the navy was founded it had grown in size to 52,000 fighting marines.


title: Song dynasty

text: The Song government confiscated portions of land owned by the landed gentry in order to raise revenue for these projects, an act which caused dissension and loss of loyalty amongst leading members of Song society but did not stop the Song's defensive preparations. Financial matters were made worse by the fact that many wealthy, land-owning families—some of which had officials working for the government—used their social connections with those in office in order to obtain tax-exempt status.


title: Song dynasty

text: Although the Song dynasty was able to hold back the Jin, a new foe came to power over the steppe, deserts, and plains north of the Jin dynasty. The Mongols, led by Genghis Khan (r. 1206–1227), initially invaded the Jin dynasty in 1205 and 1209, engaging in large raids across its borders, and in 1211 an enormous Mongol army was assembled to invade the Jin. The Jin dynasty was forced to submit and pay tribute to the Mongols as vassals; when the Jin suddenly moved their capital city from Beijing to Kaifeng, the Mongols saw this as a revolt. Under the leadership of Ögedei Khan (r.1229–1241), both the Jin dynasty and Western Xia dynasty were conquered by Mongol forces in 1233/34.


title: Song dynasty

text: The Mongols were allied with the Song, but this alliance was broken when the Song recaptured the former imperial capitals of Kaifeng, Luoyang, and Chang'an at the collapse of the Jin dynasty. After the first Mongol invasion of Vietnam in 1258, Mongol general Uriyangkhadai attacked Guangxi from Hanoi as part of a coordinated Mongol attack in 1259 with armies attacking in Sichuan under Mongol leader Möngke Khan and other Mongol armies attacking in modern-day Shandong and Henan. On August 11, 1259, Möngke Khan died during the siege of Diaoyu Castle in Chongqing.


title: Song dynasty

text: Möngke's death and the ensuing succession crisis prompted Hulagu Khan to pull the bulk of the Mongol forces out of the Middle East where they were poised to fight the Egyptian Mamluks (who defeated the remaining Mongols at Ain Jalut). Although Hulagu was allied with Kublai Khan, his forces were unable to help in the assault against the Song, due to Hulagu's war with the Golden Horde.


title: Song dynasty

text: Kublai continued the assault against the Song, gaining a temporary foothold on the southern banks of the Yangtze. By the winter of 1259, Uriyangkhadai's army fought its way north to meet Kublai Khan's army, which was besieging Ezhou in Hubei. Kublai made preparations to take Ezhou, but a pending civil war with his brother Ariq Böke—a rival claimant to the Mongol Khaganate—forced Kublai to move back north with the bulk of his forces. In Kublai's absence, the Song forces were ordered by Chancellor Jia Sidao to make an immediate assault and succeeded in pushing the Mongol forces back to the northern banks of the Yangtze. There were minor border skirmishes until 1265, when Kublai won a significant battle in Sichuan.


title: Song dynasty

text: From 1268 to 1273, Kublai blockaded the Yangtze River with his navy and besieged Xiangyang, the last obstacle in his way to invading the rich Yangtze River basin. Kublai officially declared the creation of the Yuan dynasty in 1271. In 1275, a Song force of 130,000 troops under Chancellor Jia Sidao was defeated by Kublai's newly appointed commander-in-chief, general Bayan. By 1276, most of the Song territory had been captured by Yuan forces, including the capital Lin'an.


title: Song dynasty

text: In the Battle of Yamen on the Pearl River Delta in 1279, the Yuan army, led by the general Zhang Hongfan, finally crushed the Song resistance. The last remaining ruler, the 13-year-old emperor Zhao Bing, committed suicide, along with Prime Minister Lu Xiufu and 1300 members of the royal clan. On Kublai's orders, carried out by his commander Bayan, the rest of the former imperial family of Song were unharmed; the deposed Emperor Gong was demoted, being given the title 'Duke of Ying', but was eventually exiled to Tibet where he took up a monastic life. The former emperor would eventually be forced to commit suicide under the orders of Kublai's great-great grandson, Gegeen Khan, out of fear that Emperor Gong would stage a coup to restore his reign. Other members of the Song Imperial Family continued to live in the Yuan dynasty, including Zhao Mengfu and Zhao Yong.


title: Song dynasty

text: The Song dynasty was an era of administrative sophistication and complex social organization. Some of the largest cities in the world were found in China during this period (Kaifeng and Hangzhou had populations of over a million). People enjoyed various social clubs and entertainment in the cities, and there were many schools and temples to provide the people with education and religious services. The Song government supported social welfare programs including the establishment of retirement homes, public clinics, and paupers' graveyards. The Song dynasty supported a widespread postal service that was modeled on the earlier Han dynasty (202 BCE – CE 220) postal system to provide swift communication throughout the empire. The central government employed thousands of postal workers of various ranks to provide service for post offices and larger postal stations. In rural areas, farming peasants either owned their own plots of land, paid rents as tenant farmers, or were serfs on large estates.


title: Song dynasty

text: Although women were on a lower social tier than men (according to Confucian ethics), they enjoyed many social and legal privileges and wielded considerable power at home and in their own small businesses. As Song society became more and more prosperous and parents on the bride's side of the family provided larger dowries for her marriage, women naturally gained many new legal rights in ownership of property. Under certain circumstances, an unmarried daughter without brothers, or a surviving mother without sons, could inherit one-half of her father's share of undivided family property. There were many notable and well-educated women, and it was a common practice for women to educate their sons during their earliest youth. The mother of the scientist, general, diplomat, and statesman Shen Kuo taught him essentials of military strategy. There were also exceptional women writers and poets, such as Li Qingzhao (1084–1151), who became famous even in her lifetime.


title: Song dynasty

text: Religion in China during this period had a great effect on people's lives, beliefs, and daily activities, and Chinese literature on spirituality was popular. The major deities of Daoism and Buddhism, ancestral spirits, and the many deities of Chinese folk religion were worshipped with sacrificial offerings. Tansen Sen asserts that more Buddhist monks from India traveled to China during the Song than in the previous Tang dynasty (618–907). With many ethnic foreigners travelling to China to conduct trade or live permanently, there came many foreign religions; religious minorities in China included Middle Eastern Muslims, the Kaifeng Jews, and Persian Manichaeans.


title: Song dynasty

text: The populace engaged in a vibrant social and domestic life, enjoying such public festivals as the Lantern Festival and the Qingming Festival. There were entertainment quarters in the cities providing a constant array of amusements. There were puppeteers, acrobats, theatre actors, sword swallowers, snake charmers, storytellers, singers and musicians, prostitutes, and places to relax, including tea houses, restaurants, and organized banquets. People attended social clubs in large numbers; there were tea clubs, exotic food clubs, antiquarian and art collectors' clubs, horse-loving clubs, poetry clubs, and music clubs. Like regional cooking and cuisines in the Song, the era was known for its regional varieties of performing arts styles as well. Theatrical drama was very popular amongst the elite and general populace, although Classical Chinese—not the vernacular language—was spoken by actors on stage. The four largest drama theatres in Kaifeng could hold audiences of several thousand each. There were also notable domestic pastimes, as people at home enjoyed activities such as the go and xiangqi board games.


title: Song dynasty

text: During this period greater emphasis was laid upon the civil service system of recruiting officials; this was based upon degrees acquired through competitive examinations, in an effort to select the most capable individuals for governance. Selecting men for office through proven merit was an ancient idea in China. The civil service system became institutionalized on a small scale during the Sui and Tang dynasties, but by the Song period, it became virtually the only means for drafting officials into the government. The advent of widespread printing helped to widely circulate Confucian teachings and to educate more and more eligible candidates for the exams. This can be seen in the number of exam takers for the low-level prefectural exams rising from 30,000 annual candidates in the early 11th century to 400,000 candidates by the late 13th century. The civil service and examination system allowed for greater meritocracy, social mobility, and equality in competition for those wishing to attain an official seat in government. Using statistics gathered by the Song state, Edward A. Kracke, Sudō Yoshiyuki, and Ho Ping-ti supported the hypothesis that simply having a father, grandfather, or great-grandfather who had served as an official of state did not guarantee one would obtain the same level of authority. Robert Hartwell and Robert P. Hymes criticized this model, stating that it places too much emphasis on the role of the nuclear family and considers only three paternal ascendants of exam candidates while ignoring the demographic reality of Song China, the significant proportion of males in each generation that had no surviving sons, and the role of the extended family. Many felt disenfranchised by what they saw as a bureaucratic system that favored the land-holding class able to afford the best education. One of the greatest literary critics of this was the official and famous poet Su Shi. Yet Su was a product of his times, as the identity, habits, and attitudes of the scholar-official had become less aristocratic and more bureaucratic with the transition of the periods from Tang to Song. At the beginning of the dynasty, government posts were disproportionately held by two elite social groups: a founding elite who had ties with the founding emperor and a semi-hereditary professional elite who used long-held clan status, family connections, and marriage alliances to secure appointments. By the late 11th century, the founding elite became obsolete, while political partisanship and factionalism at court undermined the marriage strategies of the professional elite, which dissolved as a distinguishable social group and was replaced by a multitude of gentry families.


title: Song dynasty

text: Due to Song's enormous population growth and the body of its appointed scholar-officials being accepted in limited numbers (about 20,000 active officials during the Song period), the larger scholarly gentry class would now take over grassroots affairs on the vast local level. Excluding the scholar-officials in office, this elite social class consisted of exam candidates, examination degree-holders not yet assigned to an official post, local tutors, and retired officials. These learned men, degree-holders, and local elites supervised local affairs and sponsored necessary facilities of local communities; any local magistrate appointed to his office by the government relied upon the cooperation of the few or many local gentry in the area. For example, the Song government—excluding the educational-reformist government under Emperor Huizong—spared little amount of state revenue to maintain prefectural and county schools; instead, the bulk of the funds for schools was drawn from private financing. This limited role of government officials was a departure from the earlier Tang dynasty (618–907), when the government strictly regulated commercial markets and local affairs; now the government withdrew heavily from regulating commerce and relied upon a mass of local gentry to perform necessary duties in their communities.


title: Song dynasty

text: The gentry distinguished themselves in society through their intellectual and antiquarian pursuits, while the homes of prominent landholders attracted a variety of courtiers, including artisans, artists, educational tutors, and entertainers. Despite the disdain for trade, commerce, and the merchant class exhibited by the highly cultured and elite exam-drafted scholar-officials, commercialism played a prominent role in Song culture and society. A scholar-official would be frowned upon by his peers if he pursued means of profiteering outside of his official salary; however, this did not stop many scholar-officials from managing business relations through the use of intermediary agents.


title: Song dynasty

text: The Song judicial system retained most of the legal code of the earlier Tang dynasty, the basis of traditional Chinese law up until the modern era. Roving sheriffs maintained law and order in the municipal jurisdictions and occasionally ventured into the countryside. Official magistrates overseeing court cases were not only expected to be well-versed in written law but also to promote morality in society. Magistrates such as the famed Bao Zheng (999–1062) embodied the upright, moral judge who upheld justice and never failed to live up to his principles. Song judges specified the guilty person or party in a criminal act and meted out punishments accordingly, often in the form of caning. A guilty individual or parties brought to court for a criminal or civil offense were not viewed as wholly innocent until proven otherwise, while even accusers were viewed with a high level of suspicion by the judge. Due to costly court expenses and immediate jailing of those accused of criminal offenses, people in the Song preferred to settle disputes and quarrels privately, without the court's interference.


title: Song dynasty

text: Shen Kuo's "Dream Pool Essays" argued against traditional Chinese beliefs in anatomy (such as his argument for two throat valves instead of three); this perhaps spurred the interest in the performance of post-mortem autopsies in China during the 12th century. The physician and judge known as Song Ci (1186–1249) wrote a pioneering work of forensic science on the examination of corpses in order to determine cause of death (strangulation, poisoning, drowning, blows, etc.) and to prove whether death resulted from murder, suicide, or accidental death. Song Ci stressed the importance of proper coroner's conduct during autopsies and the accurate recording of the inquest of each autopsy by official clerks.


title: Song dynasty

text: The Song military was chiefly organized to ensure that the army could not threaten Imperial control, often at the expense of effectiveness in war. Northern Song's Military Council operated under a Chancellor, who had no control over the imperial army. The imperial army was divided among three marshals, each independently responsible to the Emperor. Since the Emperor rarely led campaigns personally, Song forces lacked unity of command. The imperial court often believed that successful generals endangered royal authority, and relieved or even executed them (notably Li Gang, Yue Fei, and Han Shizhong).


title: Song dynasty

text: Although the scholar-officials viewed military soldiers as lower members in the hierarchic social order, a person could gain status and prestige in society by becoming a high-ranking military officer with a record of victorious battles. At its height, the Song military had one million soldiers divided into platoons of 50 troops, companies made of two platoons, battalions composed of 500 soldiers. Crossbowmen were separated from the regular infantry and placed in their own units as they were prized combatants, providing effective missile fire against cavalry charges. The government was eager to sponsor new crossbow designs that could shoot at longer ranges, while crossbowmen were also valuable when employed as long-range snipers. Song cavalry employed a slew of different weapons, including halberds, swords, bows, spears, and 'fire lances' that discharged a gunpowder blast of flame and shrapnel.


title: Song dynasty

text: Military strategy and military training were treated as sciences that could be studied and perfected; soldiers were tested in their skills of using weaponry and in their athletic ability. The troops were trained to follow signal standards to advance at the waving of banners and to halt at the sound of bells and drums.


title: Song dynasty

text: The Song navy was of great importance during the consolidation of the empire in the 10th century; during the war against the Southern Tang state, the Song navy employed tactics such as defending large floating pontoon bridges across the Yangtze River in order to secure movements of troops and supplies. There were large ships in the Song navy that could carry 1,000 soldiers aboard their decks, while the swift-moving paddle-wheel craft were viewed as essential fighting ships in any successful naval battle.


title: Song dynasty

text: In a battle on January 23, 971, massive arrow fire from Song dynasty crossbowmen decimated the war elephant corps of the Southern Han army. This defeat not only marked the eventual submission of the Southern Han to the Song dynasty, but also the last instance where a war elephant corps was employed as a regular division within a Chinese army.


title: Song dynasty

text: There was a total of 347 military treatises written during the Song period, as listed by the history text of the "Song Shi" (compiled in 1345). However, only a handful of these military treatises have survived, which includes the "Wujing Zongyao" written in 1044. It was the first known book to have listed formulas for gunpowder; it gave appropriate formulas for use in several different kinds of gunpowder bombs. It also provided detailed descriptions and illustrations of double-piston pump flamethrowers, as well as instructions for the maintenance and repair of the components and equipment used in the device.


title: Song dynasty

text: The visual arts during the Song dynasty were heightened by new developments such as advances in landscape and portrait painting. The gentry elite engaged in the arts as accepted pastimes of the cultured scholar-official, including painting, composing poetry, and writing calligraphy. The poet and statesman Su Shi and his associate Mi Fu (1051–1107) enjoyed antiquarian affairs, often borrowing or buying art pieces to study and copy. Poetry and literature profited from the rising popularity and development of the ci poetry form. Enormous encyclopedic volumes were compiled, such as works of historiography and dozens of treatises on technical subjects. This included the universal history text of the "Zizhi Tongjian", compiled into 1000 volumes of 9.4 million written Chinese characters. The genre of Chinese travel literature also became popular with the writings of the geographer Fan Chengda (1126–1193) and Su Shi, the latter of whom wrote the 'daytrip essay' known as "Record of Stone Bell Mountain" that used persuasive writing to argue for a philosophical point. Although an early form of the local geographic gazetteer existed in China since the 1st century, the matured form known as "treatise on a place", or "fangzhi", replaced the old "map guide", or , during the Song dynasty.


title: Song dynasty

text: The imperial courts of the emperor's palace were filled with his entourage of court painters, calligraphers, poets, and storytellers. Emperor Huizong was the eighth emperor of the Song dynasty and he was a renowned artist as well as a patron of the art and the catalogue of his collection listed over 6,000 known paintings. A prime example of a highly venerated court painter was Zhang Zeduan (1085–1145) who painted an enormous panoramic painting, "Along the River During the Qingming Festival". Emperor Gaozong of Song initiated a massive art project during his reign, known as the "Eighteen Songs of a Nomad Flute" from the life story of Cai Wenji (b. 177). This art project was a diplomatic gesture to the Jin dynasty while he negotiated for the release of his mother from Jurchen captivity in the north.


title: Song dynasty

text: In philosophy, Chinese Buddhism had waned in influence but it retained its hold on the arts and on the charities of monasteries. Buddhism had a profound influence upon the budding movement of Neo-Confucianism, led by Cheng Yi (1033–1107) and Zhu Xi (1130–1200). Mahayana Buddhism influenced Fan Zhongyan and Wang Anshi through its concept of ethical universalism, while Buddhist metaphysics deeply affected the pre–Neo-Confucian doctrine of Cheng Yi. The philosophical work of Cheng Yi in turn influenced Zhu Xi. Although his writings were not accepted by his contemporary peers, Zhu's commentary and emphasis upon the Confucian classics of the Four Books as an introductory corpus to Confucian learning formed the basis of the Neo-Confucian doctrine. By the year 1241, under the sponsorship of Emperor Lizong, Zhu Xi's Four Books and his commentary on them became standard requirements of study for students attempting to pass the civil service examinations. The neighbouring East Asian countries of Japan and Korea also adopted Zhu Xi's teaching, known as the Shushigaku (朱子學, School of Zhu Xi) of Japan, and in Korea the Jujahak (주자학). Buddhism's continuing influence can be seen in painted artwork such as Lin Tinggui's "Luohan Laundering". However, the ideology was highly criticized and even scorned by some. The statesman and historian Ouyang Xiu (1007–1072) called the religion a "curse" that could only be remedied by uprooting it from Chinese culture and replacing it with Confucian discourse. The Chan sect experienced a literary flourishing in the Song period, which saw the publication of several major classical koan collections which remain influential in Zen philosophy and practice to the present day. A true revival of Buddhism in Chinese society would not occur until the Mongol rule of the Yuan dynasty, with Kublai Khan's sponsorship of Tibetan Buddhism and Drogön Chögyal Phagpa as the leading lama. The Christian sect of Nestorianism, which had entered China in the Tang era, would also be revived in China under Mongol rule.


title: Song dynasty

text: Sumptuary laws regulated the food that one consumed and the clothes that one wore according to status and social class. Clothing was made of hemp or cotton cloths, restricted to a color standard of black and white. Trousers were the acceptable attire for peasants, soldiers, artisans, and merchants, although wealthy merchants might choose to wear more ornate clothing and male blouses that came down below the waist. Acceptable apparel for scholar-officials was rigidly defined by the social ranking system. However, as time went on this rule of rank-graded apparel for officials was not as strictly enforced. Each official was able to display his awarded status by wearing different-colored traditional silken robes that hung to the ground around his feet, specific types of headgear, and even specific styles of girdles that displayed his graded-rank of officialdom.


title: Song dynasty

text: Women wore long dresses, blouses that came down to the knee, skirts, and jackets with long or short sleeves, while women from wealthy families could wear purple scarves around their shoulders. The main difference in women's apparel from that of men was that it was fastened on the left, not on the right.


title: Song dynasty

text: The main food staples in the diet of the lower classes remained rice, pork, and salted fish. In 1011, Emperor Zhenzong of Song introduced Champa rice to China from Vietnam's Kingdom of Champa, which sent 30,000 bushels as a tribute to Song. Champa rice was drought-resistant and able to grow fast enough to offer two harvests a year instead of one.


title: Song dynasty

text: Song restaurant and tavern menus are recorded. They list entrees for feasts, banquets, festivals, and carnivals. They reveal a diverse and lavish diet for those of the upper class. They could choose from a wide variety of meats and seafood, including shrimp, geese, duck, mussel, shellfish, fallow deer, hare, partridge, pheasant, francolin, quail, fox, badger, clam, crab, and many others. Dairy products were rare in Chinese cuisine at this time. Beef was rarely consumed since the bull was a valuable draft animal, and dog meat was absent from the diet of the wealthy, although the poor could choose to eat dog meat if necessary (yet it was not part of their regular diet). People also consumed dates, raisins, jujubes, pears, plums, apricots, pear juice, lychee-fruit juice, honey and ginger drinks, spices and seasonings of Sichuan pepper, ginger, soy sauce, oil, sesame oil, salt, and vinegar.


title: Song dynasty

text: The Song dynasty had one of the most prosperous and advanced economies in the medieval world. Song Chinese invested their funds in joint stock companies and in multiple sailing vessels at a time when monetary gain was assured from the vigorous overseas trade and domestic trade along the Grand Canal and Yangtze River. Prominent merchant families and private businesses were allowed to occupy industries that were not already government-operated monopolies. Both private and government-controlled industries met the needs of a growing Chinese population in the Song. Artisans and merchants formed guilds that the state had to deal with when assessing taxes, requisitioning goods, and setting standard workers' wages and prices on goods.
