Yes, of course. But they do the details differently.

And critters all optimize for their own world.

Using the active voice is misleading. Random mutations mostly make their offspring less nearly optimal in their environment, but sometimes the change is for the better. It's a very wasteful way of adaption to the environment, but it does work.

Intelligent design ought to work better, and we are now almost in a position to practice it, but intelligent designers are thin on the ground, and the woods are full of designers who think that they are intelligent.

This has been done with humans too.

That's not all that difficult, only identical twins have identical genomes.

What the human tests showed up was the smell preferences lined up with difference in the genes that generated antibodies, so the selection was specifically aimed at producing off-spring who had the widest possible range of potential antibodies. Hardly anybody produces the same antibody when challenged by a foreign protein, and some antibodies work better than others.

It's called the immune system.

Half the males immune system is added to the half the kids inherits from the female, which creates it's own diversity

But not great at getting complex ideas across to unsophisticated viewers.

I wish i could say the same about you,

I watched Dutch TV and read Dutch newspapers to exercise my Dutch. My German was never that good - I could read German scientific papers, and had been doing that since I was an undergraduate, but that was pretty much my limit. My wife - whose German was as near perfect as an English speaker can manage - never watched German TV at home.

Living in the Netherlands sorted of wrecked her German - before she had moved there and learned Dutch, Germans thought that she came from Bavaria, but after she'd learned Dutch they thought that she was a Dutch person whose German was almost perfect, much to her disgust.

Max Perutz worked that out (in England) and it was indeed a brilliant piece of work. He got the Nobel Prize for it in 1962.

I suspect that depends upon "proximity" :-)
