An ancient species of human from China, thought to be long extinct, likely survived until at least the last Ice Age 14,000 years ago, new research finds.
Since the timeframe of these so-called Red Deer Cave people, as well as Homo floresiensis (aka Hobbit humans) from Indonesia, overlapped for many years with that of Homo sapiens, it is possible -- however remote -- that a human not in our species could still exist.
"It's always possible that a pre-modern human population still exists somewhere in the world," associate professor Darren Curnoe from The University of New South Wales, who co-led the new study of the Red Deer Cave people fossils, told Discovery News.

"New species are being found all of the time by scientists, but with a large-bodied species like humans, you would think it would be difficult to miss, that someone would have reported it or a scientist found it somewhere (already)," added Curnoe. "My guess is if any did exist -- and I'm doubtful -- it would be in a remote place like Siberia, but some very grandiose claims have been made about Yetis and other creatures being Neanderthals surviving today in places like Siberia."
Curnoe, co-leader Ji Xueping from the Yunnan Institute of Cultural Relics and Archaeology, and their team focused on China, however, for the recent finds. The research is outlined in the latest issue of the journal PLOS ONE.
The remains were excavated from Yunnan Province's Maludong ("Red Deer Cave") in 1989, but had lain unstudied in a southeastern Yunnan museum until now. The bones date to 14,000 years ago, according to the new analysis, and retain features of early human species like Homo habilis and Homo erectus. The researchers therefore think the Red Deer Cave people descended from one of those populations, but could represent their own unique species.

A thighbone suggests the Red Deer Cave people had a gait that was different than ours, but the precise movement has not yet been determined. The researchers, however, could deduce that these 110-pound small individuals lived at least part of the year at the cave, which was located in a tropical evergreen forest close to water. An abundance of deer bones showing signs of butchery were also found in the cave, along with evidence for large fires being built there.
Robin Dennell of The University of Sheffield's Department of Archaeology told Discovery News, "There is no doubt the material found by Curnoe and Xueping is strange, and it does push the boundaries of what we think of as Homo sapiens. My take on it is that it may well represent an archaic population that resulted from interbreeding between Homo erectus and an early immigrant population of Homo sapiens."
