Man-Chimp breakup pinpointed

By using genetic markers, scientists think they've found the point at which humans diverged from chimpanzees.
According to the new theory, the two groups split about 10 million years ago. then the two groups, um, reunited for a while, until a final split about 6 million years ago.
"It's a totally cool and extremely clever analysis," said Daniel Lieberman, a professor of biological anthropology at Harvard. "My problem is imagining what it would be like to have a bipedal hominid and a chimpanzee viewing each other as appropriate mates, not to put it too crudely."
You've obviously never met a shepherd. Not to put it too crudely.
