Actually, the beauty of Behe's argument is that NO irreducibly complex system could have evolved.
Well, this is true, but what if the system you are describing simply isn't irreducibly complex.
Am I missing something in the definition of an IC system that forces those middle ear bones to be irreducibly complex? If it were me, I'd just say that one system isn't IC, since it clearly evolved, and I'd move on to the next thing that others can't explain.
The poster of message 4 (can't remember who now) said that creationists (although Behe's not a standard creationist) would try to suggest this evolution didn't happen. Ok. Seems easier to write this one off and move to the next one.
I'm not an ICer, and I haven't studied it that much. I was sort of playing with that post. What's the definition of an IC system to Behe. If it had been me, I would have left the definition to "those systems that couldn't have evolved," and it would have been self-perpetuating.
