OUT OF AFRICA HYPOTHESIS: MORE EVIDENCE?

"There are two competing theories to explain how mankind spread across the globe. One suggests that between 100,000 and 200,000 years ago modern man (Homo sapiens) emerged from Africa to slowly populate the rest of the world, replacing any species of human that were already there. This is the Out of Africa hypothesis. The other theory suggests that modern humans arose simultaneously in Africa, Europe and Asia from one of our predecessors, Homo erectus, who left Africa about two million years ago."
