Taking on Behe's Challenge: Evolve Me a Cilium

In Darwin's Black Box (1996) and again in The Edge of Evolution (2007), Michael Behe challenged the scientific community to explain irreducibly complex molecular machines, like the cilium and bacterial flagellum, in Darwinian terms. The eukaryotic cilium, especially, represented "irreducible complexity squared," he said, with further research showing a complex transport system, Intraflagellar Transport (IFT), acting like a system of "freight cars" at a "construction site," moving cargo up and...
