Ray's quote mining a molecular biologist, James Shapiro.
I found a (newer) paper of Shapiro in an accessible form where he actually says some intelligent things in favor of evolution. I'll read it and update this when I find the time and if nobody wants to do it for me...
update: Well, what I found was the transcript from a talk. Maybe not easy to understand without the powerpoint presentation (that should be somewhere...). It's mainly about epigenetics, that the environment can have an influence on the DNA and that this is one important force in evolution. Even if changes are more or less random. But here is a transcript of the discussion. There is also a link to his homepage where you can get the actual paper.
Seems, as if he indeed is critical to Darwinism. But honestly, every biologist is that. You just can't use "The Origin of Species" as an infallible source of information and nobody does that. Research is going on and today we know a lot more than Darwin ever dreamed of. Shapiro might be extreme in his judgment of "natural genome engineering" but he's miles away from ID and creationism. AND HE DOESN'T SAY THAT EVOLUTION COULD BE WRONG, RAY (everybody else: Sorry, somehow I felt like shouting).
That's so typical: A Scientist says something like "Well, maybe our definition of evolution isn't complete" and some creotards start misquoting him.
