Evolution of the Eye

Wikipedia has a terrific, thorough and readable explanation of the evolution of the eye from earlier structures (directional photodetectors found in simple, even single-celled organisms). It has nice diagrams and pictures of the intermediate forms leading to this astonishing structure. Next time you have lunch with a Creationist or “intelligent design” proponent–who love to flog the eye as defense of their case–do your homework first.
