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.
There is no reliable evidence of modern humans elsewhere in the Old World until 60,000-40,000 years ago, Artifactual evidence indicates that modern humans were in Europe by at least 40,000 and possibly as early as 46,000 years ago.
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 supports the contention of direct genetic links between Asian Homo erectus and modern Asians.
