This chapter examines paternal relationships with sons and daughters. Identity drives investment (and parental investment in particular), because people invest in that which aligns with their identity. And biological sex drives identity. These two ideas combined imply that a parent-offspring match in biological sex can influence parental favoritism in a systematic manner, an idea supported by recent empirical studies. This parental bias of concordant-sex favoritism can have broad implications, outside the context of the traditional family structure. In single parent or same-sex parent households, the consequences of this bias can be even stronger, because there would not be an opposite-direction bias from the other parent to even things out. This favoritism could have even broader ramifications, entirely outside the context of the family. On the one hand, whenever social norms dictate that men should control a family’s financial decisions, then sons may systematically receive more resources than daughters. This asymmetry in investment would then result in ever-increasing advantages that persist over time. On the other hand, if women are a family’s primary shoppers, this can manifest in subtle but chronic favoritism for daughters.

This chapter studies the behavior of one specific group of extended family members, namely aunts and uncles. Aunts and uncles typically belong to the same generation as the children’s parents, but obviously the relations between aunts and uncles and their nieces and nephews are very different compared to parent–child relations. This is due to the fact that aunts and uncles are seldom the main caregivers of their nieces and nephews, and in contemporary Western societies, they rarely live in the same household as them. That said, however, noncoresiding aunts and uncles can serve as important alloparents for children and are often highly committed to the lives of their nieces and nephews, providing, for instance, social support, friendship, mentoring, and role models. The chapter then outlines key evolutionary theories of intergenerational family relations explaining the behavior of aunts and uncles. It also considers the investment of aunts and uncles in contemporary affluent societies.

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.

V. Glover
This chapter describes the effects of maternal prenatal stress on fetal and child development. There is considerable evidence from both animal and human studies that if the mother is stressed during pregnancy this increases the likelihood of her offspring having a range of altered behavioral and other neurodevelopmental outcomes, together on occasion with increased stress reactions. It is possible to suggest adaptive reasons for many of these effects. The behavioral outcomes, such as increased anxiety in females, will make them more vigilant and able to detect danger. More aggression in males may make them better at dealing with this danger.An increased risk of other outcomes such as preterm delivery, earlier menarche, and reduced telomere length, reflect an accelerated life history pattern from birth to death. These too may be of evolutionary advantage in conditions of external threat.
