Ancient jaw bone found in Israel shows modern humans left Africa 180,000 years ago

Modern humans were wandering out of Africa at least 180,000 years ago — some 60,000 years earlier than previously thought.  The new migration date comes after ancient stone tools and part of a fossilised Homo sapiens jaw bone with teeth were discovered in a cave in northern Israel.  Until now, the oldest evidence for modern humans outside Africa were only 90,000 to 120,000 years old.
