Ancient Hominin Skull From China Suggests Humans Didn’t Evolve Just From African Ancestors

Most scientists consider all trendy people are descended from African ancestors. But a brand new evaluation of an historical Chinese cranium discovered too many similarities to the earliest human fossils present in Africa to be a coincidence; perhaps we didn’t all originate in Africa.

Known because the Dali cranium, it was found almost 40 years in the past in China’s Shaanxi province. It belonged to a member of the early hominin species Homo erectus. Its facial construction and mind case are intact, regardless of being dated to round 260,000 years in the past. The Dali cranium is so previous that archaeologists initially didn’t consider it might share options with the fashionable Homo sapiens.

But Xinzhi Wu of the Chinese Academy of Sciences in Beijing believed that as a result of overwhelming bodily similarities, Homo erectus will need to have shared DNA with Homo sapiens. After a long time of this concept being dismissed by mainstream academia, Wu and a colleague, Sheela Athreya of Texas A&M University, lately reanalyzed the Dali cranium and located it might pressure us to rewrite our evolutionary historical past in spite of everything. It’s extremely just like two separate Homo sapiens skulls beforehand present in Morocco.

“I really wasn’t expecting that,” Athreya informed New Scientist.

If we’d discovered solely the Moroccan skulls, and never the Dali cranium, it could make sense to maintain believing all trendy people developed in Africa. But the similarities present that early trendy people could not have been genetically remoted from different elements of the world, like what we all know in the present day as China.

“I think gene flow could have been multidirectional, so some of the traits seen in Europe or Africa could have originated in Asia,” Athreya informed New Scientist.

So sure traits that we affiliate with trendy Homo sapiens could have really developed in east Asia, and have been solely later carried to Africa. We’ll nonetheless want additional comparisons between the Dali cranium and the Moroccan ones. But the implications are monumental; we’re speaking about rewriting the origins of our species as we all know it, reassessing how our ancestors migrated and interacted and subsequently developed.

“In a real sense we are talking about a multiregional population, connected recurrently by migration and genetic exchanges,” John Hawks of the University of Wisconsin-Madison informed New Scientist.
