in the pre-columbian era what were the only domesticated beasts of burden in the americas
Pre-Columbian era While not as widespread as in other areas of the world (Asia, Africa, Europe), indigenous Americans did have livestock. Domesticated turkeys were common in Mesoamerica and in some regions of North America; they were valued for their meat, feathers, and, possibly, eggs. There is documentation of Mesoamericans utilizing hairless dogs, especially the Xoloitzcuintle breed, for their meat. Andean societies had llamas and alpacas for meat and wool, as well as for beasts of burden. Guinea pigs were raised for meat in the Andes. Iguanas and a range of wild animals, such as deer and pecari, were another source of meat in Mexico, Central, and northern South America.
Horses in the United States The horse evolved in the Americas, but became extinct between 8,000 and 12,000 years ago. When the Spanish arrived on the American mainland in the 16th century, they brought horses with them and re-established the animals on the continent.
