Document Summary
A form of natural selection that occurs when individuals differ in their ability to compete with others for mates or to attract members of the opposite sex. Favors the evolution of traits that give individuals advantage in mating. Favors the evolution of traits that allow the limited sex (males in most species) to compete more effectively for access of limited sex (females) Darwin: differences in reproductive success caused by competition over mates sexual selection. In social systems where multiple males have access and male-male competition is high, sexual selection favors sperm competition. More sperm you have, the more likely you are to have offspring. Human fossil record is part of the broader field of paleontology. Where individuals exert choice among individuals of the opposite sex for mating. Favors traits that make males (usually) more attractive to females partners. Competition among same-sex individuals for access to members of the opposite.
