Document Summary
Males often suffer little cost by reproducing so don"t need to be as picky about their mate. Engage in act, but don"t go through pregnancy challenges. For many species, females are known to be more selective in mating than males. Exceptions that confirm he rule: male sea-horses are choosier as are pale phalaropes (males responsible for feed chicks) Greater burden in keeping off spring safe and raising them therefore choosier. Males and females of many species soon part after mating. However if it provides a reproductive advantage, we can expect males and females of a species to remain in contact (ex: male guarding) Polygamy: several members of one sex mating with one individual of the other. Monogamy: long-term mating relationship between one male and one female. 90% of mammals are polygamous (usually many females, one male) Birds need both parents for offspring to flourish (someone to stay and someone to find food) Win against other members of your sex.
