Red Deer Cave People

The Red Deer Cave People appear to have been some of the most unusual humans in the past 20,000 years. They have been dated to have existed about 14,000 years ago, which is exceptionally recent in terms of human evolution. Yet, their fossils display many ‘archaic’ human features that are associated with more distant relatives in the family tree.

They might have been an ancient relic of humanity that held on until the end of the last Ice Age. Or they may have been a hybrid population, possibly related to Neanderthals and Denisovans. Or perhaps they show that Homo sapiens were extremely diverse throughout their history.

In 1989, human remains were unearthed at a cave in Yunnan, southern Chine. It became known at the Red Deer Cave because of the discovery of giant red deer fossils at the site. It is believed the human inhabitants cooked and ate the animals.

In 2012, scientists speculated whether the people in the cave represented a new human species. By studying their jaws and teeth, it was noted they had thick skulls with flat faces, broad noses, small chines, large molar teeth and prominent brow ridges, all features associated with older, long-extinct members of the human family tree.

The scientists had discovered a population of prehistoric humans whose skulls display an unusual mosaic of primitive features, like those seen in our ancestors thousands of years ago.

A 2015 study of a thigh bone discovered at Red Deer Cave suggested that individual weighed about 110 pounds (50 kilograms) and shared anatomical features with early Homo erectus or Homo habilis, both of which went extinct about 1.5 million years ago.

Since the femur was dated at just 14,000 years old, this did not fit the widely accepted chronology of human evolution. This femur was part of a living person a few thousand years before Homo sapiens developed agriculture, which sparked an evolution of culture that ultimately gave rise to complex civilizations.

It suggests that primitive-looking humans might have survived until very late in our evolution. But it is just one bone. A pre-modern species may have overlapped in with modern humans on mainland East Asia, but that case needs to be built with more bone discoveries.

By 2022, advancements in ancient DNA allowed a study of Red Deer Cave hominins’ genetics. It confirmed that they were modern Homo sapiens. In fact, they had a significant genetic connection to modern East Asians and Native Americans, who descended from the same groups of people.

So the Red Deer Cave People were not as unusual as first thought, even though the small population did have features not seen in any modern population of humans. With no clear explanation why they appeared this way, it hints that humans living towards the end of the last Ice Age were more diverse than those living across the world today.
