Neanderthal DNA illuminates split with humans

The first comparison of human and Neanderthal DNA shows that the two
lineages diverged about 400,000 years ago and that Neanderthals may have
had more DNA in common with chimps than w modern humans.

The above statement is absurd and contradicts itself on the face of it to
anyone who has a clue when the human chimp split is supposed to have
occurred.

The statement could be read as a clumsy effort to say that Neanderthals
had more DNA in common with chimps than modern humans have in common
with chimps. I.e., that modern human DNA is more changed from the
DNA of the chimp/human LCA than is the DNA of the Neanderthals.
I have no idea if that is what was actually intended, but at least
it wouldn't be obvious nonsense.

Agreed. In fact, this seems to be the general
case. The first two migrations from Africa
(h.erectus at 1.7 mya and h.neandertal at
400 kya) both didn't evolve once they had
left Africa as fast as the groups left behind.
