First off, thanks to Elena for getting the ball rolling on class posts. I am another member of Allen’s class, and I too apologize for my ignorance of scientific theory. Nevertheless, I do have a few opinions to express on Behe’s “Black Box” and our class discussions.

Though I choose not to speculate on Behe’s possible motives (if there were any at all) for confusing the basic terminology of evolution/descent with modification/natural selection, I think it is important to note that after so much work was built on his own, which supposedly undermines evolution, he had a responsibility to define his views on the unanswered implications of his book, namely that his argument dispells “evolution”. Behe did not take the 10 year downtime between editions of Black Box to address what his book implied (that his theory overthrew evolution) whether he expressly stated it or not. Further, the fact that he wrote in the book that he believes the evidence supportes common descent is an even stronger reason for him to publically set the record straight on his views in the afterword of the new edition. Because he chose not to do so, it is difficult for me to believe he sincerely meant what he wrote on page 176.

In terms of the science behind Behe’s arguement (regarding which, as Darwin would put it, “my ignorance of the laws of biochemistry is profound”) the question to his underlying assumption is, I believe: are his examples really irreducibly complex? Well, it seems to me that depends on whether you consider any intermediate funtions of the proposed trait to be beneficial. Taking Behe’s popular example of the cilia: is it, with any aspect removed, still functional? As a whole cilia in the manner we know it now, no it is not. However, could these cilia have been functional in another way at an intermediate point in evolution? If so, then Behe’s concept of irreducible complexity doesn’t really challenge natural selection either. Though i recognize this logic is somewhat teleological, it is no more so than the concept of function/benefit in adaptations in general.

In a broader sense, I believe leaders of the ID movement (namely Behe and Dempski) are wrapped up in a similar problem to that which doomed some aspects of the modern synthesis: they focus to heavily on the micro-scale mathematical (and in Behe’s case biochemical) aspects of evolution, and in doing so tend to miss the forest for the trees. Often these minute changes do not even manifest at the level of phenotype upon which Darwin based his arguments for descent with modification and natural selection. In the same way that Fisher reduced natural selection to the level of alleles, Behe has reduced ID to the level of biochemical pathways. I believe these arguments tend to miss the significance of evolution on the level of phenotypes. Similarly, I believe Dawkin’s reductionist defense of evolution was equally as non-compelling. In my opinion, the most convincing argument for descent with modification and natural selection is still what I refer to as Darwin’s “look around you!” argument in the origin of species. Although this may not be based on hard math, I am not convinced that math and physics are the best means by which to judge biologoical processes. Though I realize this is a grossly over-generalized statement, please bare with me, as I am certainly not at the scientific level of those posting on this site. If someone with a greater degree of scientific understanding would like to explain why it is a good thing that biology be “more like physics/math” I would looking forward to reading it. Thank you.
