Oh deary me, are people *still* shooting at a totally discredited target?!

Quoting from "The Science of Discworld":

"The question is often asked in the form 'What use is half an eye?', to which you are expected to conclude 'nothing', followed by a rapid conversion to some religion or other. 'Nothing' is a reasonable answer -- but to the wrong question"

The fact of the matter is that the question should be *can* an eye develop to its current form from basic principles? And the answer to that is *yes*.

A study of eye-like structures will show anyone who has an open mind that an eye can evolve from a basic light sensitive patch to a fully functioning optical structure by simple changes.

Unfortunately those who want to deny evolution work this backwards by looking at the *finished* product and saying "but if we removed *this* bit it wouldn't work!" which makes as much sense as saying "This cathedral *must* have been created by God and couldn't have 'evolved' from the design of a mud hut, because if we took out *this* pillar the whole thing would fall down!"
