In the news today, a partial femur found in the Red Deer Cave in China might show that a archaic species of human may have overlapped with modern humans until the end of the ice age.
Since 2001 I have supported the theory that the main racial divisions among humans (Caucasoids, Negroids, Mongoloids, Australoids) were caused by admixture between Homo sapiens and archaic groups of humans.
It appeared to me that Europeans, and especially Northern Europeans, had a lot of physical similarities with Neanderthals as I explained here.
I also saw similarities between Mongoloid people and the Peking man, a Homo erectus species who lived in East Asia. This discovery is probably the missing link I had been looking for.
DNA showed that things were more complex than I thought since all non-Africans have Neanderthal DNA, and back migrations to Africa brought trace frequencies of Neanderthal DNA in Africans too (more than traces in North Africans and Ethiopians). Denisovans also left genetic traces in East Asians, although the closest modern race are the Australoids. In other words, Neanderthal and Denisovan ancestry is shared among Mongoloid and Australoid people, but at different frequencies. There was obviously another archaic population that made Mongoloids look so completely different from Australoids, and they may well be related to this 14,000 year-old Homo erectus.
