Biologist Kenneth Miller thought he had scored a point against biochemist Michael Behe’s concept of irreducible complexity. At a conference, says Miller, “I removed two parts from a mousetrap (leaving just the base, spring, and hammer), and used that 3-part device as a functional tie-clip.” Check out this bonus video from the Science Uprising series, where Behe amusedly tells what’s wrong with Miller’s demonstration:

He also explains the “edge of evolution,” which he has traced to the level of biological family, as in cats versus dogs. Down to that level in the taxonomic scheme, evolution must reflect intelligent design. Further down, Darwinian processes may reign, primarily by breaking, though, rather than building. The author most recently of Darwin Devolves, Behe is a pleasure to learn from, as always.
