Differential Parental Investment, Jose C. Yong, Norman P. Li

Research Collection School of Social Sciences

Differences in minimum obligatory parental investment contributed by men and women lead the sexes to diverge in their sexual strategies and affective experiences, although under certain conditions, men’s mating preferences converge with women’s. This chapter first describes necessary or obligatory parental investment, examines the origins of sex differences in obligatory parental investment, describes examples of such differences across a range of species, and highlights the consequences of these differences in terms of human sexual strategies, conflicts, and affective experiences.
