Francis Collins Commits “Berra’s Blunder” in Defending Macroevolution

On this ID the Future from the vault, Casey Luskin highlights a glaring logical error in the pro-evolution book The Language of Science and Faith by Francis Collins and Karl Giberson. There Collins and Giberson assert that macroevolution is merely microevolution over long ages, and to cinch their argument they point to the observed macroevolution of … birds? No. Whales? No. A new land mammal? A fundamentally new type of bacteria? No again, and understandably so since no one has observed the macroevolution of any biological form. The idea is conjectural. So what example do Collins and Giberson offer? The evolution of automobiles from the Model T to the Toyota Prius hybrid. But as Luskin notes, such an evolutionary path illustrates something quite different from mindless Darwinian evolution.
