On this episode of ID the Future, CSC’s Casey Luskin interviews Senior Fellow Michael Behe, the well known author of Darwin’s Black Box, and more recently, The Edge of Evolution. Behe shares his work on the bacterial flagellar motor and explains why, in his view, the flagellum is irreducibly complex. Behe also examines the two currently proposed evolutionary explanations for the assembly of the flagellum, co-option and homology, showing why both proposals fall short in uncovering the origins of this molecular machine.
