I have to agree with what Chris said about the eye.
It is an absurdity to suggest that the eye simply arose spontaniously, which is why it's no suprise that the people saying "the eye developed spontaniously" are creationists, not evolutionists.
I've never heard an evolutionist say that the eye simply arose spntaniously, it's always been discussed in the form of how it was likely to have developed, from light responsive cells (you have some of these at the back of your knees if memory of jet lag treatments serves) through to more developed organs.
