Why would an intelligent designer (eg. God) design humans (and most other mammals actually) with really shoddely wired retinas?
In the eyeball, which most creationists seem to tote as being an example of a designer, all the light sensitive cells of the retina are partially covered with nerves and blood vessels that block light and inhibit vision. Not only that but where these nerves and blood vessels leave the eye the light sensetive cells are pushed aside which creates a blind spot.
Molluscs such as octopii and squids don't have this problem as their retinas are "wired" in a more appropriate fashion, from the back, so no light is blocked and no blind spot exists.
So going by this, what basis is there that the human (or rather generic mammal) eyeball is intelligently designed?
