"The kin selection hypothesis posits that male androphilia evolved because androphilic males invest more in kin, thereby enhancing inclusive fitness." However, increased kin-directed altruism has only been seen in societies that exhibit transgendered male androphilia. To test the validity of the kin selection hypothesis for male androphilia, the authors examine the relationship between ancestral sociocultural conditions, access to kin, and societal reactions to homosexuality and the expression of male androphilia as transgendered or non-transgendered. They find that ancestral sociocultural conditions and bilateral and double descent systems were more common in transgendered than non-transgendered societies.

Previous studies have proposed a model of sexual selection that dictates that along with female and male choice, parental choice constitutes a significant sexual selection force in our species. This article aims at examining whether this model can also account for the mating patterns typical of agricultural and pastoral societies. The hypotheses are supported by the results presented.

This article offers an analysis of the rape of women cross-culturally, positing that rape is present under certain cultural circumstances. The author tests for correlations between rape and aspects of sexual repression, group violence, childrearing, and ideologies of male dominance. There are significant associations between male sexual violence and other types of violence, as well as between rape and ideologies of male dominance.

This article re-examines Abernethy's (1974) hypothesis that female power within a marriage negatively affects male sexual functioning. Results do not support this hypothesis.

This study focuses on preferences for thinness or fatness in women cross-culturally. Results contradict previous studies and the hypothesis that preference for fatness in women is predicted by resource scarcity. Alternative explanations for valuation of fatness are explored, including climate and male dominance.

The authors of this study investigate both intimate partner violence (IPV) in Africa and tolerance towards it. Merging Demographic and Health Survey data with information from the Ethnographic Atlas, they take into account a wide range of ancestral characteristics that could influence domestic violence today, including precolonial economic roles and marriage traditions. Their findings indicate that societies in which men were dominant in subsistence and/or had androcentric marital practices have more IPV today, and more acceptance of it. They also find an interesting gender gap in acceptance of IPV, in which women are more likely than men to justify domestic violence.

This book explores the factors that affect sexual inequality. The author first focuses on the symbolic representations of a culture's "sex-role plan," or how male and female power is scripted in different societies. The author then tests the relationships bewteen sexual inequality and variables like subsistence strategy, division of labor, and menstrual and sex taboos. The bases of female power and the rise of male dominance are also discussed.
