The January 2009 issue of Trends in Microbiology contains an article entitled “Bacterial flagellar diversity and evolution: seek simplicity and distrust it?”  Unfortunately, like many people, the authors have a mistaken view of irreducible complexity, as well as a very shallow idea of what a Darwinian “precursor” to an irreducibly complex system might be. I wrote a letter to the editor of the journal to point out these difficulties. Alas, they said they had no room to publish it. Below is the letter that I sent. To the editor: In their recent article “Bacterial flagellar diversity and evolution: seek simplicity and distrust it?” Snyder et al. (2009) [1] attribute to me a view of irreducible complexity concerning the flagellum that I do Read More ›

Dear Readers, This is the third in a series of responses I’m posting this week. In “Evolution of the Bacterial Flagellum” (Microbe Magazine, July 2007), Wong et al seek to counter arguments of intelligent design proponents such as myself that the flagellum did not evolve by random mutation and natural selection. Unfortunately, their otherwise-fine review misunderstands design reasoning and so fails to engage that issue. The critical passage from Wong et al is the first paragraph: Proponents of the intelligent design (ID) explanation for how organisms developed claim that the bacterial flagellum (BF) is irreducibly complex. They argue that this structure is so complicated that it could not have emerged through random selection but had to be designed by an Read More ›
