Humans Migrated Out of Africa to Escape Drying Climate

Ancient humans left Africa to escape a drying climate, about 60,000 years ago — a finding that contradicts previous suggestions that humens were able to leave because a then-wet climate allowed them to cross the generally arid Horn of Africa and Middle East. The study is published in the journal Geology.

“It has long been proposed that the out-of-Africa migration was facilitated by wet periods that created green corridors to Eurasia — in other words, the climate pulled people out. We may have to revise this model to one where people were pushed out, due to unfavorable conditions,” said study co-author Dr. Peter deMenocal, of Columbia University.
