[QUOTE]Originally posted by Djehuti: [QB] [QUOTE]Originally posted by Ish Gebor: [QUOTE][i]Khoisan hunter-gatherers have been the largest population throughout most of modern-human demographic history The Khoisan people from Southern Africa maintained ancient lifestyles as hunter-gatherers or pastoralists up to modern times, though little else is known about their early history. Here we infer early demographic histories of modern humans using whole-genome sequences of five Khoisan individuals and one Bantu speaker. [i]Comparison with a 420 K SNP data set from worldwide individuals demonstrates that two of the Khoisan genomes from the Ju/’hoansi population contain exclusive Khoisan ancestry. Coalescent analysis shows that the Khoisan and their ancestors have been the largest populations since their split with the non-Khoisan population ~100–150 kyr ago.[b] In contrast, the ancestors of the non-Khoisan groups, including Bantu-speakers and non-Africans, experienced population declines after the split and lost more than half of their genetic diversity. [/b]Paleoclimate records indicate that the precipitation in southern Africa increased ~80–100 kyr ago while west-central Africa became drier. We hypothesize that these climate differences might be related to the divergent-ancient histories among human populations. [...] Yet Khoisan populations have maintained the greatest nuclear-genetic diversity among all human populations3, 4, 5 and the most ancient Y-chromosome and mitochondrial DNA lineages6, 7, implying relatively larger effective population sizes for ancestral Khoisan populations.[/i] [/QUOTE][qb] http://www.nature.com/ncomms/2014/141204/ncomms6692/full/ncomms6692.html [/qb][/QUOTE]This study only reaffirms my point even more about loss of genetic diversity through time as well as not stereotyping Africans much less 'Sub-Saharans'. Here you have the Khoisan who [i]are[/i] a Sub-Saharan group yet their DNA profile is distinct from other more typical Sub-Saharan groups. By the way, this study seems to support Ehret and other linguists who hypothesize an overall linguo-genetic split of click-speakers from non click-speaking peoples that took place in Africa well before initial OOA.
