Using an evolutionary perspective, this study tests hypotheses relating gender and kinship roles to the amount of direct and indirect care provided during and around childbirth. The roles of paternal certainty, residence rules and descent groups are also examined.

This article focuses on parents’ investment of material resources at the time of their child’s marriage. Two patterns emerge from the data: wealth is generally transferred from the groom’s family to the bride’s and from the couple’s parents to the bride and groom. Social and ecological factors are also examined. Multiple regression analysis shows that paternal confidence level, societal polygyny rate, and level of pathogen stress can affect the aforementioned wealth transfer patterns.

This study examines several aspects of human society that are associated with underlying patterns of genetic relationships. Results suggest that paternity certainty (measured by female extramarital promiscuity) is related to kinship terminology systems and marriage systems.

This article examines the results of a study (Gaulin 1980) on male parental certainty and subsistence type. Methodological errors are assessed and the hypotheses are retested.

This study tests competing theories about whether it is men, women, or parents who benefit most from restricting female premarital sex (FPS) in a global sample of 128 non-industrial societies. The study found support for the idea that multiple parties benefit from restrictions on FPS -- specifically FPS is more restricted in societies intolerant of extramarital sex and where men transfer property to their children (male control), as well as where marriages are arranged by parents (parental control). They also found that major predictors of FPS appear to be paternity uncertainty and parent-offspring conflict. Furthermore, the study found that multiple factors such as social roles, rather than stereotyped sex roles, are a more useful approach in understanding FPS restrictions and these restrictions.

This study examines the double standard regarding extramarital norms for men and women in relation to other sociocultural factors. Results suggest that a double standard is significantly related to post-partum sex taboos, hypermasculinity, and father absence.
