Not of my religion!! LOL Eyes are frequently used as a "too complex for Darwinism" examples, but I demur. Seems to me the basic mechanisms above could account for the transition from a single twitching light-sensitive cell, to the whole tri- or tera-color sensitive rod and cone arrangement used by mammals today. But as I say I am still chewing this whole thing over. I used to feel strongly that the random chance model was preposterous for the very reason you cite, but Dawkins has made it clear that I was misunderstanding the theory.
