A human-like species in southeast China has found recently. These fossils estimated between 11,500 and 14,500 years ago. Chinese scientists have presented theory about an unknown Stone Age culture, researchers said Wednesday.
“We have discovered a new population of prehistoric humans whose skulls are an unusual mosaic of primitive features, like those seen in our ancestors hundreds of thousands of years ago,” evolutionary biologist Darren Curnoe of the University of New South Wales, said via email.
“In short, they’re anatomically unique among all members of the human evolutionary tree,” added Curnoe, a co-author of the new study of the “Red Deer Cave people,”
“These new fossils might be of a previously unknown species, one that survived until the very end of the Ice Age around 11,000 years ago,” said lead author Darren Curnoe, a professor at the University of New South Wales.
“Alternatively, they might represent a very early and previously unknown migration of modern humans out of Africa, a population who may not have contributed genetically to living people.”
“First, their skulls are anatomically unique,” he said. “They look very different to all modern humans, whether alive today or in Africa 150,000 years ago. And second, the very fact they persisted until almost 11,000 years ago when we know that very modern-looking people lived at the same time immediately to the east and south suggests they must have been isolated from them.”

“They clearly had a taste for venison, with evidence they hunted and cooked these large deer in the cave,” Curnoe explained.

“Second, the very fact they persisted until almost 11,000 years ago—when we know that very modern-looking people lived at the same time immediately to the east and south—suggests they must have been isolated from them,” Curnoe added.
“It’s possible these were modern humans who inter-mixed or bred with archaic humans that were around at the time,” explained Dr Isabelle De Groote, a paleoanthropologist from London’s Natural History Museum.

“The other option is that they evolved these more primitive features independently because of genetic drift or isolation, or in a response to an environmental pressure such as climate.”

Dr Curnoe agreed all this was “certainly possible”.
