Climate-driven out of Africa dispersal of humans

A new study published in the journal Quaternary International suggests that out of Africa dispersal of anatomically modern humans happened much earlier than initially thought. Michael Petraglia from the Department of Archaeology at the University of Oxford, a co-author of the study, said in a statement for UPI that “the consensus view has been that modern humans left Africa around 60,000 years ago by a coastal route, skirting around some very arid places, and spread to Australia very quickly. We think that’s wrong. We think people left Africa multiple times, probably a long time before, and we think it was terrestrial rather than coastal. “We know that the climate has shifted a lot of times,” he said. “We think that has acted like a pump out of Africa, pushing waves of people into South Asia.”
