I have spent most of my life as an evolutionist. I have abandoned my commitments to Santa Claus and the Easter Bunny and Jean Luc Picard, but I have stubbornly adhered to Darwinism. And it’s a good thing I’m as stubborn as I am1 because it’s becoming increasingly difficult.

Human beings are the problem. I’m just fine with tiny horses that evolved into Clydesdales and dinosaurs that turned into robins. I’m even okay with fish that sprouted legs and developed into golden retrievers.2
