Oldest Human Fossil Found Outside Africa

A human fossil found in Isreal in 2002 now shows that humans may have left Africa up to 100,000 years earlier than originally thought. Researchers spent one and a half decades studying an upper jawbone and stone tools found in a cave in Isreal.

The jawbone was found with teeth that were thought to be between 170 000 and 190 000 years old.  CT scans helped to build a 3D model, which researchers then compared with other fossils from Africa, Asia and the Middle East.

The tools found nearby suggest that prehistoric people were busy making various objects that they used for hunting animals and gathering.  While some scientists say that the tools could only have been made by homo sapiens, modern people, others do not ignore the fact that Neanderthals could also have made them.

Up to now, the oldest fossils found outside Africa were also located in Israel. According to archaeologists, they were no more than 90,000 to 120,000 years old.

The new discovery also sets back the date at which homo sapiens appeared in Africa. While the current theory says that they originated in Africa 200,000 years ago, we now may believe that they actually showed up between 300,000 and 500,000 years ago. If that is true, then they probably left Africa on short trips to other continents as early as 200,000 years ago.
