This study tests the hypothesis that humans tend to transmit wealth to male heirs where polygyny is possible. The results support this hypothesis.

This book is a comprehensive analysis of many aspects of social structure including family, clan, community, kinship terminology, social organization, regulation of sex, incest taboos, and sexual choice.

This study tests the hypothesis that humans tend to transmit wealth to male heirs where polygyny is possible. The results support this hypothesis.

This article provides a new explanation of matrilineal inheritence and paternity certainty, suggesting that matrilineal inheritance is most advantageous for women and can be described as a grandmaternal strategy. Results suggest a strong relationship between matrilineal inheritance and moderate to low probability of paternity, and an even stronger relationship between patrilineal inheritance and high probability of paternity.

Using paternal investment theory, the authors examine the relationship between paternal confidence and paternal investment in humans.

This article examines the relationship between inheritance and paternity certainty. Results indicate an "association between relatively frequent female extramarital sex and a cultural norm that allows men to designate heirs whose relatedness is relatively unaffected by low probability of paternity."

"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.

The study is about matrilineal systems, where descent is traced along female lines. Matrilineal systems are relatively rare in human populations, and previous research has discussed the rarity and apparent instability of matriliny. The study aims to study the evolution of descent systems on a worldwide scale. The study tests for significant associations between matriliny and numerous cultural traits that have been theoretically associated with its stability or loss, such as subsistence strategy, animal domestication, mating system, residence pattern, wealth transfer, and property succession. Additionally, by combining genetic and linguistic information to build a global supertree that includes 16 matrilineal populations, the study also performs phylogenetically controlled analyses to assess the patterns of correlated evolution between descent and other traits.

This article examines the restriction of women in religious ritual, focusing on cultural traits that favor men's power. Results suggest that patrilineality and male inheritance correlate with the restriction of women’s participation in ritual.

This study examines cross-cousin marriage preferences from an evolutionary perspective. Results suggest significant associations between cross-cousin marriage preferences and both polygyny and residence.
