Ancient structure in Africa unlikely to explain Neanderthal and non-African genetic similarity

MA Yang, AS Malaspinas, EY Durand… - Molecular biology and …, 2012 -
Abstract Neanderthals have been shown to share more genetic variants with present-day
non-Africans than Africans. Recent admixture between Neanderthals and modern humans
outside of Africa was proposed as the most parsimonious explanation for this observation.
However, the hypothesis of ancient population structure within Africa could not be ruled out
as an alternative explanation. We use simulations to test whether the site frequency ...
