A team of European and Moroccan scientists has found the fossil remains of five individuals who they believe are the most ancient modern humans (Homo sapiens) ever found.In a remote area of Morocco called Jebel Irhoud, in what was once a cave, the team found a skull, bones and teeth of five individuals who lived about 315,000 years ago. The scientists also found fairly sophisticated stone tools and charcoal, indicating the use of fire by this group.The researchers' claim is controversial, however, because anthropologists are still debating exactly what physical features distinguish modern humans from our more primitive ancestors.
