[QUOTE]Originally posted by Ish Gebor: [QB] [QUOTE]Originally posted by xyyman: I guess you did not read it either. Now I have. Quote: “We estimate that the [b]Eurasian R1b lineages initially diverged 7,300–9,400 ya[/b], at the time of [b]****the Neolithic expansions****[/b]. However, we found that the [b]African and Eurasian R1b lineages diverged 17,900–23,000 ya,[/b] suggesting that genetic structure was already established between the groups who expanded to Europe and Africa. R1b-V88 was previously found in Central and West Africa” explain this to me. And don’t let that VMAT1 gene get the better of you! Also this. “The Toubou, despite their Islamic faith, [b]do not show the genetic admixture detected in many Near Eastern and North African populations[/b] around 1,100 ya” “Eurasian backflow into Africa thus appears to have been a [b]recurrent event [/b]in the history of many Africans, given its[b]considerable impact on their genomes[/b]” “This suggests that R1b penetrated Africa independently of the Afro-asiatic language spread or passed to other groups through admixture” --- What do you think MansaMusa? Anything sticking? Have I struck gold …again. [/QUOTE]This info correlates with the following. [QUOTE] Nevertheless, Villabruna 1, more then the majority of his contemporaries, retains climatic adaptation typical of the ancestral African population. [/QUOTE] [QUOTE] These data suggest that while Villabruna 1 retains more ancestral condition indicative of African origin than its contemporaries, this specimen fits well in the microevolutionary process that affected European Upper Paleolithic populations leading to the progressive acquisition of body proportions typical of temperate regions. [/QUOTE] [QUOTE]However, mitocondrial DNA analyses carried out on prehistoric human remains from this region highlighted in Villabruna 1 a sequence not observed in contemporary European populations (Di Benedetto et al., 2000), raising the possibility of genetic discontinuity between the last hunter-gatherers from the Alps and subsequent populations.
