Now, I'm not a scientist, but... could evolution, say, find a way to get around the not-very-long-lived vision that is perhaps the limitation of the squid or octopus eye? That is to say, if humans happened to share an ancestor with the aforementioned cephalopods and inherited their "sensible" eye, would that have necessarily modified our evolutionary path to meet the constraints of said "sensible" eye, or could humans have evolved an even more suitable "sensible" eye to overcome the problem of not-very-long-lived vision?
I'm sure there would have to be other ways. like developing pigment in that jelly stuff inside your eye (I'm science me
) or over the cornea such that we have natural sunglasses.It's not hard to imagine other ways it would be possible.
