Sexual selection is a mode of natural selection where members of one biological sex choose mates of the other sex to mate with intersexual selection , and compete with members of the same sex for access to members of the opposite sex intrasexual selection. These two forms of selection mean that some individuals have better reproductive success than others within a population , either from being more attractive or preferring more attractive partners to produce offspring. The females then arrive and choose the males with the deepest croaks and best territories. Generalizing, males benefit from frequent mating and monopolizing access to a group of fertile females. Females have a limited number of offspring they can have and they maximize the return on the energy they invest in reproduction. The concept was first articulated by Charles Darwin and Alfred Russel Wallace who described it as driving species adaptations and that many organisms had evolved features whose function was deleterious to their individual survival,  and then developed by Ronald Fisher in the early 20th century. Intrasexual selection (mate competition) is one type of sexual selection, where members of the same sex compete with one other for members of the opposite.
