Now all you have to do is tie these cute little drawings to
real creatures and prove there was a sequential evolution.
They are real creatures, currently living ones.
My point is not that one is descended from another, but that functional eyes include many levels of complexity. It is unnecessary to start with the most complex version.
Humans, by the way, have nothing close to the best or most complex eyes. there are predator eyes that are far sharper and which have better color vision.
