At the top, we can see African populations, at the bottom non-African populations. It's nothing special since it has been demonstrated many times that almost all black African people have their origin in Northeastern Africa at a period of time postdating the OOA migrations. From where they later immigrated in the Green Sahara and eventually in the rest of Africa. For example, most Africans are from the E haplogroups or have their language family originating there in Northeastern Africa. [/qb][/QUOTE]This chart does not prove that modern Africans priginated in East Africa, . [/qb][/QUOTE]It is a strong indication, although it does not prove it by itself, but both genetic and linguistic analysis of most modern African people demonstrates they had their origin relatively recently, later than the OOA migrations, in northeastern Africa. The rest of your post comes back to ignoring any kind of morphological study of human remains to analyse population affiliation because of local adaptation. Physiological traits, like post-cranial morphology, are both (genetically) inherited and influenced by local variations. In the graph posted we see both similarities and differences between African post-cranial data. African populations are at the top and cluster with one another, non-African populations are at the bottom, while at the same time African population expresses differences between one another even within the same population (same for European and other population of course see for example France and Germany two neighboring countries). Still, basically African populations cluster with one another at the top and non-African at the bottom. In particular, East and West Africans don't just share post-cranial physiological similarities but also the same genetic origin as most of them are from the E-P2 haplogroups which originated in northeastern Africa. As for the genetic and linguistic origin of most modern African people in Northeast Africa, I made many elaborate threads and posts about it, but this is enough to make my point: [b]LINGUISTIC ORIGIN OF MOST MODERN AFRICAN PEOPLE[/b] : [IMG]http://www.ephotobay.com/image/geo-origin-of-african-languages-chap-12-reconstr.jpg[/IMG] [i]Reconstructing Ancient Kinship in Africa by Christopher Ehret (From Early Human Kinship, Chap 12)[/i] Clearly all modern African language families are said to have originated in Northeastern Africa. [b]GENETICS ORIGIN OF MOST MODERN AFRICAN PEOPLE[/b] : [QUOTE] Using the principle of the phylogeographic parsimony, the resolution of the E1b1b trifurcation in favor of a common ancestor of E-M2 and E-M329 strongly supports the hypothesis that haplogroup E1b1 originated in [b]eastern Africa[/b] , as previously suggested [10], and that chromosomes E-M2, so frequently observed in sub-Saharan Africa, [b]trace their descent to a common ancestor present in eastern Africa[/b] . [/QUOTE]-- from [i]A New Topology of the Human Y Chromosome Haplogroup E1b1 (E-P2) Revealed through the Use of Newly Characterized Binary Polymorphisms[/i] (Trombetta 2011) The same probably can be said about (downstream or midstream) A and B haplogroups carrier populations (like Khoisan, many Nilo-Saharans), even more so considering their linguistic origin. E and E-P2 is the dominating lineage across Africa. [/qb][/QUOTE]I wonder why you're trying to segregate African people. Like that old colonial divide and conquer.
