Briefly explain the parental investment theory, and describe the research findings on human gender differences in sexual activity
What will be an ideal response?
Evolutionary factors in human sexual behavior are theorized to hinge on parental investment, with females being more discriminating in choosing partners and less likely to engage in casual sex. According to parental investment theory, males are thought to compete with other males for reproductive opportunities and females are assumed to be the discriminating sex that is selective in choosing partners. This theory has been used to explain observed sex differences such as males thinking about sex more frequently, males emphasizing youthfulness and attractiveness in a potential partner, and females emphasizing status and financial prospects in a potential partner.
