DNA study: Human-chimp split was messy

DNA study: Human-chimp split was messy

The researchers hypothesize that an ancestral ape species split into two isolated populations about 10 million years ago, then got back together after a few thousand millennia. At that time the two groups, though somewhat genetically different, would have mated to form a third, hybrid population. That population could have interbred with one or both of its parent populations. Then, at some point after 6.3 million years ago, two distinct lines arose.

The "Post Modern Human" / "Primative Human" split is just beginning.

It's already messy.
