****************************************
Genetic evidence for complex speciation of humans and chimpanzees

Nick Patterson, Daniel J. Richter, Sante Gnerre, Eric S. Lander
and David Reich

The genetic divergence time between two species varies substantially
across the genome, conveying important information about the timing
and process of speciation. Here we develop a framework for studying
this variation and apply it to about 20 million base pairs of aligned
sequence from humans, chimpanzees, gorillas and more distantly
related primates. Human-chimpanzee genetic divergence varies from
less than 84% to more than 147% of the average, a range of more
than 4 million years. Our analysis also shows that human-chimpanzee
speciation occurred less than 6.3 million years ago and probably more
recently, conflicting with some interpretations of ancient fossils.
Most strikingly, chromosome X shows an extremely young genetic
divergence time, close to the genome minimum along nearly its
entire length. These unexpected features would be explained if
the human and chimpanzee lineages initially diverged, then later
exchanged genes before separating permanently.

It seems that somebody just couldn't leave their chimp alone.

NashtOn, what are your thoughts about this?
It's in your genes you know.


There's a chimp in his/her jeans? Sounds personal to me.

The initial draft of the above suggested nash couldn't leave his
chimp alone but I erred on the mild side in the posted reply.
(This is not to suggest that a person of such moral integrity
or even their long forgotten ancestors would do such a thing.)

The answer is simple: Jabriol has discovered, or will discover, time
travel.
