If this interpretation of the fossil record is correct, all people today share a relatively modern African ancestry.
All other lines of humans that had descended from Homo erectus presumably became extinct.
By 115,000 years ago, early modern humans had expanded their range to South Africa and into Southwest Asia (Israel) shortly after 100,000 years ago.
Rather, they interbred to a limited degree with late archaic .
During this long time period, it is argued that interbreeding occurred and that the partially hybridized predominantly Cro-Magnon population ultimately became modern Europeans.
This supports the contention of direct genetic links between Asian Homo erectus and modern Asians.
Alan Thorne of the Australian National University believes that Australian aborigines share key skeletal and dental traits withuer, of the University of Hamburg in Germany, proposes that the first modern humans did evolve in Africa, but when they migrated into other regions they did not simply replace existing human populations.
As a consequence there was a major ecosystem disruption resulting in the rapid decline of both non-human carnivores and their prey.
Humans were very likely the trigger that set off this "trophic cascade".
The video below presents evidence of pockets of archaic humans surviving in West Africa until at least 13,000 years ago. Along the way, some of them interbred with archaic humans, including both Neandertals and Denisovans.
Genetic markers from these archaic human populations are found in the gene pool of some Southern Chinese, New Guinean, and other Micronesian Island populations today.
This is supported by the fact that most skeletons of Neandertals and Cro-Magnon people do not show hybrid characteristics.
