Abstract (Summary)

This study found support for hypotheses of mate preferences derived from parent-offspring conflict theory. To increase their inclusive fitness benefit, parents are expected to manipulate the choices of their children in selecting mates toward individuals who are likely to invest in grandchildren and cooperate with the in-group. By contrast, Children are expected to prefer traits that signal genetic quality and phenotypic condition when selecting mates. Additionally, due to a common reproductive interest, the preferences of parents and their children are expected to overlap. Data for this analysis were collected among a small, matrilocal, hunter-horticultural community in the Ecuadorian Amazon. Informants rated all married men in the community in terms of their qualities as sons-in-law, husbands, warriors, hunters, fathers as well as their relative social status and attractiveness. Warriorship was defined as a signal of in-group cooperation in this study because warrior quality is an important aspect of male coalitions in this population. Hunting ability was defined as a signal of parental investment potential because fathers are responsible for provisioning their families with hunted game and attractiveness was used as a signal of genetic quality. Multiple linear regression analyses demonstrated that, as expected, son-in-law quality is best predicted by husband quality, warrior quality and hunting ability, while holding all predictors constant. Also as expected, husband quality is best predicted by attractiveness, while controlling for all other predictors.
