Many prey species use camouflage to hide from predators. But other prey species, like zebras, have very prominent stripes that seem to make them stand out rather than hide. So why have stripes not.

The Descent of Man, and Selection in Relation to Sex (1871) lays out how the principle of sexual selection could produce the splendid variety of animal life forms. This was Darwin’s way of explaining how human beings descended from animals. More to my point, however, this was Darwin’s way of accounting for the variations required before his principle of natural selection could promote some.
