[QUOTE]Originally posted by MindoverMatter718: [QB] Of course non Africans were in Africa first and then migrated out, but they were still Africans while in Africa before leaving. This is noted due to the fact that East Africans carry the ancestral lineages for all non Africans, this is why Ethiopians and Somalis appear intermediate as explained. Of course Tishkoff is not saying the non African population became non African inside of Africa and left non African genetic diversity in East Africa, that doesn't even make sense, they were still African while in Africa hence the genetic diversity was/is African.. When the East African population migrated out of Africa never to return is when the linages that derived from then on became non African, and sorry but as Tishkoff notes this intermediate position is due to local evolution and NOT admixture with Eurasians! Take note; [i]Comparative genetic studies on geographically diverse populations provide evidence of high levels of diversity in continental Africa. Sarah Tishkoff and her colleagues (1986) find an intermediate pattern of genetic variation at the CD4 locus in northeastern [b](actually Horn)[/b] African populations. [b]They explain this by local evolution and not by admixture with Eurasians.[/b] In essence they are describing a gradient of differentiation. The Horn, largely at the latitude of Nigeria, contains a subset of the diversity seen in other African regions. Tishkoff and her colleagues suggest that the Horn's inhabitant's are the local descendants of those who left Africa to populate the world.[/i] -- S.O.Y. Keita Also note; Cavalli-Sforza: Genes, Culture, and Human Evolution. Pg 187. [i]..."In other words, all non-Africans carry M168. Of course, Africans carrying the M168 mutation today are the descendants of the African subpopulation from which the migrants originated.... [b]Thus, the Australian/Eurasian Adam (the ancestor of all non-Africans) was an East African Man." [/b] [/i] [/QB][/QUOTE]
