So, just what are we talking about?

So as I understand it, they have proven we descended from apes, however we also did not evolve, as they would have us believe. We mutated from them (an extremely rare event I understand).

Nope. Evolution is based upon mutation. If you read The Origin of Species (which I have not done in a while, so my memory is foggy), you will find that it contains several examples of just this sort of thing- features present in humans that are not really useful, although they are present and useful in other species.

While this study adds to the evidence that supports the hypothesis that humans are related to other species, any one factor on its own could hardly be considered "proof". I don't doubt that there is a "jaw size" gene that mutated in early humans. But, I wouldn't jump to all of the conlcusions that seem to be drawn from this finding. It's important to look at every hypothesis (aliens, jaw size, whatever) with skepticism, or just about everything will start to be believable. At that point, what do you do when one guy's "aliens from Betelgeuse" theory contradicts another's "aliens from Sirius" theory?
