One of the things that I do not understand about evolution is how animals have evolved so that they can blend into their surroundings with camouflage. It doesn't make sense that certain bugs would have random mutations that would make them look like a leaf or other bugs that resemble twigs. These insects resemble leaves or twigs with such great detail. How could mutations create this detail? There would have to be many many mutations and they would have to happen A LOT...but mutations are very rare- so I find this hard to believe.
Furthermore, if some bug just randomly mutated to the color green, then how come we still don't observe bugs randomly mutating and having different colored bodies?
