â€śThere is this pattern where ancient kinds of Homo that have been doing perfectly well for a very long time disappear as soon as Homo sapiens shows up. According to Tocheri, â€śif the erosion had continued for just a little longer, then the entire skeleton would more than likely have been lost forever.â€ť 
 
 View Images Archaeologists excavate in Liang Bua cave, the site where the "hobbit" humans were discovered in 2003. Discovered in 2003 in Liang Bua cave, Homo floresiensis stood about three and a half feet (1.1 meters) tall and weighed around 75 pounds (35 kilograms). Bert Roberts of the University of Wollongong and co-author of the study, which appeared in Nature, told Discovery News: "The earliest known evidence of modern humans on Flores is from about 11,000 years ago and after, but we do know that modern humans were on other islands in the region around this time and had reached Australia by 50,000 years ago.

 The latest excavation, instead, found that the Hobbits' skeletal remains date from 100,000 to 60,000 years ago, but stone tools consisting of hammered flakes and cores that were made by the Hobbits continue until about 50,000 years ago. Tolkien's famous novels, the real-life hobbits made stone tools and might have survived predatory attacks from komodo dragons.
– New research suggests it's possible ancient humans are responsible for killing off Indonesia's hobbits (an urge no doubt felt by modern humans who sat through the extended edition of The Hobbit). Starting in 2003 when their remains were first discovered on the island of Flores, scientists believed Homo floresiensis—who averaged 3.5 feet tall and 75 pounds—lived until as recently as 12,000 years ago, National Geographic reports. But a new study published this week in Nature found they actually died off sometime between 60,000 and 50,000 years ago—right around the time humans showed up in the area. "The exact cause of the demise of the hominids … is not yet understood, but in my view, may be related to the appearance in the area of the most aggressive of all hominin species, Homo sapiens, modern humans," one expert tells Discovery. Discovery calls the timing of the hobbits' disappearance "suspicious," but the study found no proof they were wiped out by humans, and further excavations on Flores are needed. Other possible causes for the extinction of Homo floresiensis include volcanoes, overhunting of pygmy elephants, and climate change. But it's not just their death that is mysterious. Scientists still don't know why these real-life hobbits were so small, how they got to Flores, or if they're even a different species. Some experts have posited they are actually humans suffering from dwarfism or Down syndrome. (Meanwhile, ancient humans having sex with Neanderthals may be why we have allergies.)
