Tracing human origins

Out of Africa we may have come, but what happened next? Archaeologists have provided ample evidence that our modern human ancestors, Homo sapiens, spread from Africa to the rest of the world between about 200 000 and 50 000 years ago. For many years, however, they have debated whether these explorers completely replaced the local populations of early humans, including the Neanderthals — whose ancestors had left Africa around 1.5 million years ago — or whether they interbred for a while before gradually taking over.KeywordsHuman OriginNature Publishing GroupThorny ProblemArchaeological BoneCell IotaThese keywords were added by machine and not by the authors.
