From wikipedia about sexual selection:
Sexual selection, a concept introduced by Charles Darwin in his 1859 book On the Origin of Species, is a significant element of his theory of natural selection. The sexual form of selection
“ ... depends, not on a struggle for existence, but on a struggle between the males for possession of the females; the result is not death to the unsuccessful competitor, but few or no offspring.[1] ”
“ ... when the males and females of any animal have the same general habits ... but differ in structure, colour, or ornament, such differences have been mainly caused by sexual selection.[2] ”
His sexual selection examples include ornate peacock feathers, birds of Paradise, the antlers of stag (male deer), and the manes of lions.
Darwin greatly expands his initial three-page treatment of Sexual Selection in the 1871 book The Descent of Man and Selection in Relation to ***. This 900-page, two-volume work includes 70 pages on sexual selection in human evolution, and 500 pages on sexual selection in other animals.[3] In summary, while natural selection results from the struggle to survive, sexual selection emerges from the struggle to reproduce.
“ The sexual struggle is of two kinds; in the one it is between individuals of the same ***, generally the males, in order to drive away or kill their rivals, the females remaining passive; whilst in the other, the struggle is likewise between the individuals of the same ***, in order to excite or charm those of the opposite ***, generally the females, which no longer remain passive, but select the more agreeable partners.
