  What do proponents of this theory have to say about the Bonnethead shark?

  Pat, I was going to say exactly the same thing! Bonnetheads are practically intermediate. And lets not forget winghead sharks, which are even more extreme than hammers. Are they suggesting that all three of those evolved independently as an overnight mutation? I think arguments based on sensory ecology and hydrodynamics are much more compelling.
