First, let me quote part of Michael Behe's argument, from his book, The Edge of Evolution, that humans and chimpanzees share a common ancestor:
"More compelling evidence for the shared ancestry of humans and other primates comes from their hemoglobin — not just their working hemoglobin, but a broken hemoglobin gene, too.  In one region of our genomes humans have five genes for proteins that act at various stages of development (from embryo through adult) as the second (betalike) chain of hemoglobin. This includes the gene for the beta chain itself, two almost identical copies of a gamma chain (which occurs in fetal hemoglobin), and several others. Chimpanzees have the very same genes in the very same order. In the region between the two gamma genes and a gene that works after birth, human DNA contains a broken gene (called a "pseudogene") that closely resembles a working gene for a beta chain, but has features in its sequence that preclude it from coding successfully for a protein.
"Chimp DNA has a very similar pseudogene at the same position. The beginning of the human pseudogene has two particular changes in two nucleotide letters that seems to deactivate the gene. The chimp pseudogene has the exact same changes. A bit further down in the human pseudogene is a deletion mutation, where one particular letter is missing. For technical reasons, the deletion irrevocably messes up the gene's coding. The very same letter is missing in the chimp gene. Toward the end of the human pseudogene another letter is missing. The chimp pseudogene is missing it, too.
"The same mistakes in the same gene in the same positions of both human and chimp DNA. If a common ancestor first sustained the mutational mistakes and subsequently gave rise to those two modern species, that would very readily account for why both species have them now. It's hard to imagine how there could be stronger evidence for common ancestry of chimps and humans.
"That strong evidence from the pseudogene points well beyond the ancestry of humans. Despite some remaining puzzles,  there's no reason to doubt that Darwin had this point right, that all creatures on earth are biological relatives." (p. 71-72)

There should be nothing surprising about the fact that Behe believes in common descent. He admitted as much in his first book, Darwin's Black Box, plus in frequent presentations and debates. But it surprised some people, such as Jerry Coyne, when he read Behe's argument for common descent in EOE. Okay, I don't expect critics to pay attention to all the details.
But I do expect fellow proponents of ID to pay attention. That brings me to the blog, Uncommon Descent. There are many critics of common descent at UD. No surprise there. They very often refer to people who believe in common descent as "98 percenters." And the tone they use toward these people seems to be a bit, well, snooty, and occasionally downright hostile. Again, no big surprise there.
What surprises me is that UD has become the second home of Behe's blog. Have people such as Denyse O'Leary and Cornelius Hunter ever read EOE? If not, they may be in for a surprise of their own, someday.
So that no one will think that Behe is saying that neo-Darwinism can account for common descent, I'll add the next paragraph from his book:
"The bottom line is this. Common descent is true; yet the explanation of common descent — even the common descent of humans and chimps — although fascinating, is in a profound sense trivial. It says merely that commonalities were there from the start, present in a common ancestor. It does not even begin to explain where those commonalities came from, or how humans subsequently acquired remarkable differences. Something that is nonrandom must account for the common descent of life."
