And in summary, each time a random mutation produced a variant organism with
increased ability to perceive light and process it, it survived better than
those variants who did not.....???
So when we run of energy and the world cools down, those with wolfman
syndrome (hyper -something? Producing excessive body hair) will be selected
for survival ahead of the rest of us..?

But the convergences don't end there. The extraordinary convergences don't
