I read this thread very carefully, and most of the articles linked to.

The last image (table of skulls) makes it looks like modern humans evolved from modern chimpanzees, as opposed to a common ancestor that looks dissimilar to either.
Where's the corresponding image of the progression of chimp skulls (or any primate skulls) through the ages? That, IMHO, would help a little if you are assuming (and you are assuming) that we share a common ancestor with primates.
I see two very distinct groupings of creatures in that image. A-E, to me, looks like primates, and F-L looks like humans... and the more I look at them all and compare them, the more the groups distinguish themselves.

Couldn't the fact that great apes and chimps both have 48 chromosomes, and we have 46, point to (in any realm of possibility) the fact that primates and humans DO NOT share a common ancestor? Isn't that AT LEAST a possibility? Isn't it a possibility that there were, at one time, a much larger variety of human-like beings, and ape-like beings, and most of them simply died out? Or even that humans changed, but to the degree being claimed?
Someone made a point about horse and mule interbreeding, and lions and tigers... you do realize that all asses (as far as I know,) and most ligers/tigons, are infertile? From what I've read, liger females are usually fertile, but the males are never(?).
When an interbred animal is consistently infertile, I consider that to be nature trying to tell us something. What, exactly, I won't go into.
Summary:
The more I look at evolution, the more I see the possibility of a common ancestor, and what the reasoning is behind that belief... but I'm always blindsided by how you evolutionists are just as stubborn as the creationists. Jumping from "it looks like we share an ancestor" to "yes, we absolutely share an ancestor" when there are gaps in the evidence is just as wrong as ignoring all the scientific evidence that's been gathered, IMHO.
