[QUOTE]Originally posted by xyyman: [QB] In case you have NOT connected the dots. The authors either don't understand what they are seeing relative to West Africans with "Eurasian" haplotypes or are deliberately misleading the readers. Keep in mind Islands off Africa and Coastal West Africans carry a high frequency of R1b* which is assumed to be Eurasians. Cape Verde, Soa Tome Principe etc carry a higher frequency of blacks with blue eyes along with R1b*. Do you understand what I am getting at? This "Eurasian" admixture they are seeing in coastal West Africans are are remnant genes from Paleolithic Europeans like La Brana who had blue eyes and black skin. More blacks of paleolithic Europe was recently released in the new paper yesterday. Coastal and island West Africans carry a much higher frequency of La Brana genes than inland African. It is called isolation. They got the dating screwed up ...that is all. ----- Quote: Many West African groups show evidence of admixture within the [b]last 4 ky involving African and Eurasian [/b]sources. The [b]Mossi from Burkina Faso have the oldest inferred date of admixture, at roughly 5000BCE[/b]. Across East Africa Niger-Congo speakers (orange) we infer admixture within the last 4 ky (and often within the last 1 ky) involving[b] Eurasian sources on the one hand, and African sour- ces containing ancestry from other Niger-Congo speaking African groups from the west[/b], on the other. Despite events between African and Eurasian sources appearing older in the Nilo-Saharan and Afroasiatic speakers from East Africa, we see a similar signal of very recent Central West African ancestry in a number of Khoesan groups from Southern Africa, such as the Khwe and /Gui //Gana, together with Malawi-like (brown) sources of ancestry in recent admixture events in East African Niger-Congo speakers. Most events involved sources where Eurasian (dark yellow in Figure 3A) groups gave the largest amplitudes. In considering this observation, it is important to note that the amplitude of LD curves will partly be determined by the extent to which a reference population has differentiated from the targe [/QB][/QUOTE]
