As has been repeatedly explained by many of us ID sympathizers, and which is all over the ID literature, common descent is not the point of contention. As @EricMH just Pointed out just a few posts above (With which I specifically highlighted my agreement)…
And as I explained at length to @Shekar on the post outlining my skepticism…
And as Michael Behe spelled out in his first book…
I find the idea of common descent (that all organisms share a common ancestor) fairly convincing, and have no particular reason to doubt it. I greatly respect the work of my colleagues who study the development and behavior of organisms within an evolutionary framework, and I think that evolutionary biologists have contributed enormously to our understanding of the world. Although Darwin’s mechanism—natural selection working on variation—might explain many things, however, I do not believe it explains molecular life.
