Israeli archaeologists say they may have found the earliest evidence yet for the existence of modern man. A Tel Aviv University team excavating a cave in central Israel said Monday they found teeth about 400,000 years old. The earliest Homo sapiens remains found until now are half as old. Archaeologist Avi Gopher says further research is needed to solidify the claim. If it does, he says, 'this changes the whole picture of evolution.'(AP Photo/Oded Balilty)
