Dembski has a post making an absolutely silly argument about vestigial structures. Actually two silly arguments. Here’s the first one:
Vestigial structures in biology are commonly cited as evidence for evolution, and it may well be that they did evolve. But if it is evidence of evolution, it is evolution in the wrong direction — it’s not the sort of function enhancing/innovating evolution that is supposed to give evolutionary theory its bite. Vestigial structures, after all, are structures that have lost their function. If all of evolution proceeded in this fashion, we’d quickly descend to a world of nonfunctionality.
Well no kidding, Bill. If selective pressure made every single structure in an organism superfluous at the same time, every organism would be non-functional. Thank you so much for pointing that out, Captain Obvious. Of course, that’s an impossible hypothetical so what his point could possibly be is up to you to speculate. This is a pointless bit of irrelevancy that would leave even John Madden wondering why anyone would bother to say it. Here’s the second silly argument:
But vestigiality need not evolve by purely material means — it can also be designed. I was delighted to be informed (after my recent debate with Michael Shermer at Bridgewater College) of a nifty example of vestigial structures that arise not through “devolution” but rather through design, to wit, vestigial running boards on older automobiles.
What an odd argument – “I found something that humans designed that had an unnecessary aspect to it; therefore, God would have created things just like that too.” As if God learned how to design from his own creation? Just bizarre reasoning. Of course, the good thing about invoking God as an explanation for things is that He could have created absolutely anything in any way at his whim. There is no possible artifact that one could find that could not be explained as having been created by God. After all, he works in mysterious ways. And if he just happened to want to create in a manner that mimics evolution, who are you to question him?
