A large-scale movement of people from west Eurasia into Ethiopia around 3,000 y ago resulted in the dispersal of west Eurasian ancestry throughout eastern Africa. This was then followed by a migration of an admixed population from eastern Africa to southern Africa, with admixture occurring ∼1,500 y ago. Continue reading
