Thanks C-man. It is the original paper. I have now read it, but it's going to take a long time to digest it. I'm sure I'll miss some of the finer points.
But it fits very well with the 99+% coding similarity between Man and Chimps and the other 1+% difference that is in non-coding parts of the DNA. An earlier thread showed differences in promoters as does this paper. Clearly the change in expression affects cognitive abilities and there is also probably some developmental effects.
I think our Creo friends are eventually going to have to admit that Chimps are a lot closer to us than they look. This paper also shows how the rapid evolution of Man could occur from our last common ancestor. You bone guys should like it too.
If I were a young scientist just starting out, I'd head for the molecular basis of development. There's gold in them thar hills.
