DNA
from a man who lived about 4,500 years ago in what’s now Ethiopia has
illuminated a surprisingly influential migration of Eurasians into
Africa 1,500 years after his death.
That back-to-Africa trek occurred around 3,000 years ago and left a substantial genetic imprint on populations now living throughout sub-Saharan Africa, say University of Cambridge evolutionary biologist Marcos Gallego Llorente and his colleagues. The East African man’s genome, the first map of ancient human DNA from Africa, helped to determine that a population closely related to Europe’s first farmers made major inroads in Africa, the researchers report online October 8 in Science.
