Fitness Terrains and Their Challenge to Darwinian Theory

David Klinghoffer

A new episode of ID the Future on fitness terrains is quite relevant to the fish-to-man question I wrote about earlier today. Evolutionists picture major innovations in the history of life as no big deal. Forget fish-to-man — consider the more modest challenge of fish-to-amphibian, as Dr. Miller notes.

As Center for Science & Culture research coordinator Brian Miller explains in a conversation with Sarah Chaffee, minor changes (microevolution) lie with the reach of unguided Darwinian processes. But major inventions are a different story.

Remember, in the Darwinian understanding, every modification, building up successively over generations, must be advantageous to survival and reproduction or, at worst, neutral. From human innovation, he gives the example of trying to transform a car into a helicopter. Imagining such a thing necessarily entails catastrophic losses of function along the way, something that evolution could never tolerate.

Brian Miller is a fine and lucid science explainer. Listen to the episode here, or download the podcast here.
