Scientists Narrow The Time Limits For The Human And Chimpanzee Split

"A research team proposes that the time when the most recent common ancestor of humans and their closest ape relatives -- the chimpanzees -- lived was between 5 and 7 million years ago -- a sharper focus than previous estimates of anywhere from 3 to 13 million years ago. Gene studies are needed because the interpretation of the earliest fossils of humans at the ape/human boundary are controversial and almost no fossils of chimpanzees have been discovered."
