When you send in a hundred troops in jungle wear, and a hundred in artic wear into a jungle to a fight, and at the end of the week there are more survivors among the jungle camo wearing troops than the artic snow camo troops, it does not mean that the artic troops evolved into jungle camo troops. Nobody thinks certain colors don’t have survival advantages in certain situations.
Wow, you completely missed the point.
If arctic troops were BORN in those colors and jungle troops born in theirs, and if we were talking about what the population looks like after ten generations of jungle warfare, then you would have a valid analogy.
Moths can’t pick what colors they wear. They are born in them. If white moths get eaten by birds at double the rate that black moths do, in a few generations you find very few white moths.
This is evolution by natural selection, no more, no less.
Two insects, one of which looks 5% like a piece of stick, the other looks 1% like a stick, the difference due to genes. If birds eat one more than the other, then in a few hundred generations you get insects looking 99.9% like a stick.
That’s evolution. On the human time scale you can seen it in bacteria and insects, for the longer scale there’s the fossil record.
