Behe's Irreducible Complexity Is Refuted

Indeed we have not. And we don't need to in order to refute Behe. IC is a claim that something cannot evolve; all that is necessary to refute that is to show that it could evolve, not that it did evolve.If Behe had claimed that the ear did not evolve, that would be a different story; but that's not what he claimed (perhaps because then his argument-from-ignorance would be painfully obvious instead of slightly concealed).

True, but irrelevant to radioisotope dating (and making that statement is evidence of a lack of knowledge of dating), and off-topic for this thread. Care to discuss it at Distinguishing Pb from Pb????

Of course, the classic and oft-repeated (in many different systems and manners) experiment that shows that mutations are random with respect to need is the Luria & Delbruck Fluctuation Test. It's been pretty solidly proven that mutations are random, not the result of some pre-programmed ability.
