As we celebrate the online release of Revolutionary: Michael Behe and the Mystery of Molecular Machines, documenting the ideas and influence of biochemist Michael Behe, we are delighted to present this classic ID the Future podcast. On the episode, Casey Luskin interviews Behe about a highly relevant peer-reviewed scientific paper he published in The Quarterly Review of Biology.

Dr. Behe explains why most examples of evolution in bacteria and viruses entail loss or modification of function rather than gain of a new function at the molecular level. Yet gain of function is precisely what people think of when they think of “evolution.” This, it seems, would pose a severe challenge to Darwinian explanations of molecular evolution. Listen to the conversation here.
