As far as I can tell, the entire "Out of Africa" model taken for granted within the MSM is being treated with increasing skepticism/nuance by scientists actually studying the facts on the ground, leading to these odd & increasingly ancient "first modern out of Africa" stories which may be confusing the public more than they're illuminating the history of human populations.<p>Razib Khan had a good short primer on this topic a little while back [1], excerpt:<p><i>The data for non-Africans is rather unequivocal. The vast majority of (>90%) of the ancestry of non-Africans seems to go back to a small number of common ancestors ~60,000 years ago. Perhaps in the range of ~1,000 individuals. These individuals seem to be a node within a phylogenetic tree where all the other branches are occupied by African populations. Between this period and ~15,000 years ago these non-Africans underwent a massive range expansion, until modern humans were present on all continents except Antarctica. Additionally, after the Holocene some of these non-African groups also experienced huge population growth due to intensive agricultural practice.<p>To give a sense of what I’m getting at, the bottleneck and common ancestry of non-Africans goes back ~60,000 years, but the shared ancestry of Khoisan peoples and non-Khoisan peoples goes back ~150,000-200,000 years. A major lacunae of the current discussion is that often the dynamics which characterize non-Africans are assumed to be applicable to Africans. But they are not.</i><p>[1] <a href="https://www.gnxp.com/WordPress/2017/04/28/beyond-out-of-africa-and-multiregionalism-a-new-synthesis/" rel="nofollow">https://www.gnxp.com/WordPress/2017/04/28/beyond-out-of-afri...</a>
