[QUOTE]Originally posted by Ish Gebor: [QB] [QUOTE]Originally posted by xyyman: [qb] In short they are trying to “explain away” the presence of European and Asian “LABELLED” genes in Africans and particularly West Africans, the so-called “true Negro”. Lol! But some authors have already identified ‘European’ genes in the true Negro. In fact some authors have identified the ‘European’ genes as being OLDER in the true negro compared to the “Caucasoid Horners’. Which is baffling these researchers. But it is only baffling to them because of their hypocritical views and prejudices. DNATribes in their digest on continental populations had already identified ‘Basque” ie European genes in Central Africa, and it increase in frequency moving away from Central Africans. ie IBD or genetic surfing. Lazaridis and DNATribes also identified archaic genetic material primarily in Khoi-San and Mbuti. This is puzzling the racialist because at first they believed there was no Neanderthal admixture in SSA. Lol! They are hitting roadblocks at every turn. [/qb][/QUOTE]Brenna Henn, in this 2014 interview on population genetics and population structure, considering African populations. “African populations have the most genetic diversity in the world,” Henn said.“If you compared people from the Kalahari Desert to people from Mali, they’d be as different from each other [genetically] as Italians and Chinese people.” Why are other populations of humans so much less genetically varied than Africans? The answer, Henn explains, lies in our ancestors’ history; the groups of people that migrated out of Africa and spread throughout other continents were smaller subsets of that original, genetically diverse population.

The ancestral population in Africa was sufficiently large to build up and retain substantial genetic diversity. [/QUOTE]--Brenna M. Henna, L. L. Cavalli-Sforzaa,1, and Marcus W.
