Team of Researchers Says Humans May Have Left Africa Earlier than Thought

Team of Researchers Says Humans May Have Left Africa Earlier than Thought: "WASHINGTON (AP).- Modern humans may have left Africa thousands of years earlier than previously thought, turning right and heading across the Red Sea into Arabia rather than following the Nile to a northern exit, an international team of researchers says. Stone tools discovered in the United Arab Emirates indicate the presence of modern humans between 100,000 and 125,000 years ago, the researchers report in Friday's edition of the journal Science. While science has generally accepted an African origin for humans, anthropologists have long sought to understand the route taken as these populations spread into Asia, the Far East and Europe. Previously, most evidence has suggested humans spread along the Nile River valley and into the Middle East about 60,000 years ago. 'There are not many exits from Africa.
