In cooperatively breeding mammals and birds, intra-sexual reproductive competition among females may often render variance in reproductive success higher among females than males, leading to the prediction that intra-sexual selection in such species may have yielded the differential exaggeration of competitive traits among females.

Charles Darwin proposed that all breathing species were derived from ordinary ancestors. The primary mechanism he proposed to explain this detail was natural selection: However he noted that there were various examples of elaborate, and according to the grapevine non-adaptive, sexual traits that would clearly not aid in the survival of their bearers.
He suggested that such traits effectiveness evolve if they are sexually selected, that is if they increase the individual's reproductive star, even at the expense of their survival Darwin Darwin noted that sexual selection depends on the struggle between males to access females. He highly praise two mechanisms of sexual selection: The idea of cumbersome traits evolving to aid males appear in competition during aggressive encounters was readily accepted by scientists tersely after Darwin's publication.
However, the idea of female mate cream was received with ridicule, in addition to was not seriously reconsidered await nearly 80 years later Cronin In the 40 years since, there has been greatly progress in our understanding of how sexual selection operates.

A good example of intrasexual selection, in which males fight for dominance over a harem of females, is the elephant seal — large, oceangoing mammals of the genus Mirounga. There are two species:
