This suggests that modern brain structures emerged from Africa later than early wanderers out of the continent by at least 100,000 years.
“There must have been two ‘out-of-Africa’ dispersals of early Homo: the first is documented by the fossil evidence from the site of Dmanisi in today’s Georgia†about 2 million years ago, the researchers said in their email.“It does not really change our understanding of Homo sapiens, but it definitely changes the way we look at early human brain evolution,†said Amélie Beaudet, a paleoanthropologist at the University of Cambridge who was not affiliated with the recent study, in an email.
