Parental Influence and Sexual Selection

This chapter addresses how the genetic relatedness between parents and their children results in the two parties having converging as well as diverging interests. In the domain of mating, these interests, along with other factors such as the trade-offs inherent in mating, give rise to an opportunity cost of free mate choice: Parents have much to lose if they allow their children to exercise choice freely. This opportunity cost provides a strong incentive to parents to influence their children’s mate choices. In preindustrial societies, parents manage to exercise direct control, which is predominantly manifested in the institution of arranged marriage. In postindustrial societies, parents exercise influence indirectly through manipulation. Ultimately, parental influence over mating gives rise to a sexual selection force, namely parental choice, which may be unique to the human species.
