In biology, mating is the pairing of opposite sex or hermaphroditic organisms for copulation and, in social animals, also to raise their offspring. For animals, mating methods include random mating, disassociate mating, assortative mating, or a mating pool.
In some birds, for example, it includes nest building and feeding offspring. The human practice of making domesticated animals mate and of artificially inseminating them is part of animal husbandry.
Copulation is the union of the sex organs of two sexually reproducing animals for insemination and subsequent internal fertilization. The two individuals may be of opposite sexes or hermaphroditic, as is the case with, for example, snails.
Game theoretic model of conditional human mating strategies that integrates currently disconnected bodies of data into a single mathematically explicit theory of human mating transactions. The model focuses on the problem of how much resource a male must provide to a female to secure and retain her as a mate.
Early pre evolutionary formulations proposed that men and women were identical in their mating motivations. Most were simplistic, typically postulating a single motive for matin the search for similarity, equity, or complementarity.
Given the large sex differences in human reproductive biology, notably women bearing the burdens of internal fertilization and a greater obligatory parental investment, it would be extraordinarily unlikely that evolution by selection would fail to forge sex differentiated mating strategies.
Empirical research over the past 15 years has robustly confirmed evolutionary predictions in the domains of desire for sexual variety, the importance of fertility cues, and the importance of resource provisioning. Recent work has revealed a hidden side of women sexuality a desire for extra pair partners and the conditions under which this desire is expressed. The theoretical and empirical outlines of an evolutionary formulation of human mating strategies.
