D(AltaiNea, CAnc; Mota, X), where AltaiNea is the Altai Neanderthal, MezNea is the Mezmaiskaya Neanderthal, CAnc is the reconstructed human-chimpanzee common ancestor, Mota is the reference and X is the tested genome. The absence of a West Eurasian component in Mota supports the dating of the backflow into Africa, which, at ~3.5kya, is younger than our ancient genome (dated to 4.5 cya). Given that Mota predates the backflow, it potentially provides a better unadmixed African reference than contemporary Yoruba. Thus, we recomputed the extent of the West Eurasian component in contemporary African populations using Mota, λMota,Druze, instead of Yoruba in our f4 ratio. By using this better reference, we estimated West Eurasian admixture to be significantly larger than previously estimated, with an additional 6-9% of the genome of contemporary African populations being of Eurasian origin (Fig. S6, and Table S5). Importantly, this analysis shows that the West Eurasian component can be found also in West Africa (Fig. S6), albeit at lower levels 13 than in Eastern Africa. Importantly, a sizeable West Eurasian component is also found in the Yoruba and Mbuti, which are often used a representative of an unadmixed African population. [/QUOTE]--M. Gallego Llorente Ancient Ethiopian genome reveals extensive Eurasian admixture throughout the African continent Remarkable, isn't it? And to know that he Neanderthals originated in Africa is even more diluting or is it mind-blowing?
