Mating strategies overlap with reproductive strategies, which encompass a broader set of behaviors involving the timing of reproduction and the trade-off between quantity and quality of offspring (see life history theory). Relative to other animals, human mating strategies are unique in their relationship with cultural variables such as the institution of marriage.〔Low, B. S. (2007). Ecological and socio-cultural impacts on mating and marriage. Oxford Handbook of Evolutionary Psychology, 449.〕 Nevertheless, commonalities can be found between humans and nonhuman animals in mating behavior (see animal sexual behavior). == Theoretical background == Research on human mating strategies is guided by the theory of sexual selection, and in particular, Robert Trivers' concept of Parental Investment. Trivers defines parental investment as “any investment by the parent in an individual offspring that increases the offspring's chance of surviving (and hence reproductive success) at the cost of the parent's ability to invest in other offspring.” Trivers posited that differential parental investment between males and females drives the process of sexual selection, which leads to the evolution of sexual dimorphism in mate choice, competitive ability, and courtship displays (see also secondary sex characteristics). In humans, females make a larger parental investment than males (i.e. nine months of gestation followed by childbirth and lactation). While human males invest heavily in their offspring as well, their minimum parental investment is still lower than that of females. Hence, evolutionary psychologists have predicted a number of sex differences in human mating strategies. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Human mating strategies」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
