We discussed this topic in class. Here's a physicist named Machio Kaku pontificating about evolution. Kaku is an expert on string theory. I wonder how he'd feel if a typical evolutionary biologist answered a question about string theory?
A curious aspect of the theory of evolution is that everybody thinks he understands it.
UPDATE: John Hawks weighs in with Kaku cockup.
