The History of African Gene Flow into Southern Europeans, Levantines, and Jews

摘要: Previous genetic studies have suggested a history of sub-Saharan African gene flow into some West Eurasian populations after the initial dispersal out Africa that occurred at least 45,000 years ago. However, there has been no accurate characterization proportion mixture, or its date. We analyze genome-wide polymorphism data from about 40 groups to show almost all Southern Europeans inherited 1%–3% ancestry with an average mixture date around 55 generations ago, consistent North end Roman Empire and subsequent Arab migrations. Levantine harbor 4%–15% 32 close political, economic, cultural links Egypt in late middle ages. also detect 3%–5% eight diverse Jewish we analyzed. For admixture, obtain estimated 72 generations. This may reflect descent these common ancestral population already had prior Diasporas.
