It is actually explained in the OA the issues with the mammalian eye. One issue they didn't mentioned is the hacky way we (primates) got colour vision via gene duplication of the red light receptor to form the green receptor. This makes primates prone to colour blindness due to recombination between the red and green receptor genes. Any system that results in ~5% of males having colour vision problems is a pretty bad system. The cephalopod eye is better in almost every respect to the vertebrate eye. Not only isn't it wired in backwards, it can regrow if damaged. If there is a designer God, his second attempt was certainly the cephalopod eye.

How certain are we that the visual configuration of those ~5% males aren't an intermediary step towards better human sight, a benign mutation? They might even have better sight than us normies already only we haven't the technology yet to take advantage of it. Given the right glasses maybe they can see to Mars. Or maybe once we live on Mars, they are the ones with the better eye sight and we are considered the ones with a flaw.

  Very. Colour vision defects are not something you really want to have.

    I know many who have them and know they are crippling but in another type of world where our colors aren't as important, would these defects still be a handicap? Or have we manufactured a society that cripple those with a certain gene combination? Edit: spelling

      Actually modern society protects those that have colour vision defects much more than societies of the past. In the past if your vision wasn't perfect you tended to die, now days you can be completely blind and live a long life. Colour vision is not much help under low light conditions which is the reason our distant shrew-like ancestors lost their colour vision in the first place.

        >> Colour vision is not much help under low light conditions which is the reason our distant shrew-like ancestors lost their colour vision in the first place. You seem to have authority, clearly, but doesn't your statement very precisely support my claim that we are now living in a society that dis-favor the color-blind? Our ancestors lost their ability to distinguish colors but now (all of a sudden) color seems very important. So we have in fact started, very recently, to select for non-color blindness. No?
