The early modern humans who made it to Eurasia later died out, the researchers note, and Neanderthals continued to dominate the continent for another 200,000 years or so. Hidden in the Neanderthal genome, however, were remnants from this ancient encounter.This was surprising, since most interbreeding between modern humans and Neanderthals likely happened in Eurasia. It raised questions about how Neanderthal DNA, typically associated with Eurasian ancestry, could be seemingly abundant in Africa.
To address that, they analyzed a wider range of modern genomes, representing 180 people from 12 genetically diverse populations in Botswana, Cameroon, Ethiopia, and Tanzania.
