Sexual selection is a form of natural selection where one sex prefers a specific characteristic in an individual of the other sex.Peafowls exhibit sexual selection in that peahens look for peacocks with more "eyes" on their tail feathers." His work divided sexual selection into male-male competition and female choice.

The maintenance of sexual reproduction in a highly competitive world is one of the major puzzles in biology given that asexual reproduction can reproduce much more quickly as 50% of offspring are not males, unable to produce offspring themselves.

Many non-exclusive hypotheses have been proposed, Sexual selection was first proposed by Charles Darwin in The Origin of Species (1859) and developed in The Descent of Man and Selection in Relation to Sex (1871), as he felt that natural selection alone was unable to account for certain types of non-survival adaptations.

He once wrote to a colleague that "The sight of a feather in a peacock's tail, whenever I gaze at it, makes me sick!

In his opinion, ascribing mate choice to females was attributing the ability to judge standards of beauty to animals (such as beetles) far too cognitively undeveloped to be capable of aesthetic feeling.

Ronald Fisher, the English statistician and evolutionary biologist developed a number of ideas about sexual selection in his 1930 book The Genetical Theory of Natural Selection including the sexy son hypothesis and Fisher's principle.
