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 paper examines the distribution and diffusion of the seven patterns of sibling classifaction given by the author. The author then studies the association between descent and sibling terminology.

This study examines previous hypotheses concerning kinship terminologies, particularly the development of bifurcate merging. The roles of moieties, exogamy, unilinear kin groupings, unilinear descent, and preferential mating are considered.

This study re-examines patterns of cross-sex kin relationships using new ethnographic data. The author looks specifically at cross-sex kin relationship in relation to marriage rules.

This study re-examines the hypothesis of Sapir (1916) regarding the relationship between levirate and sororate and kinship terminology. The author critiques Murdock’s (1947) work on this topic and performs his own analysis for four hypotheses. Results suggest that “the levirate and sororate are significantly correlated to the occurrence of bifurcate merging terminology and step-bifurcate collateral terminology” (352). Exceptions to this finding are also discussed.

Using phylogenetic comparative methods, the study explores the evolution of kinship terminologies within 176 societies in Austronesian, Bantu, and Uto-Aztecan language families. The authors consider 18 theories in the anthropological record that suggests that change in kinship terminologies is predicted by some social structures: marriage, residence, and descent. Only 19 of the 29 statistical hypotheses are supported, while none of the theories are supported in all three language families. This statistical irregularity means that the results are lineage-specific, instead of showing a universal driver of change in kinship terminology types.

After noticing that there are no cross-cultural phylogenetic studies of grandparent terminologies, the authors use the record from 134 Pama-Nyungan languages to explore the evolution of this kinship category and to evaluate the effects of social structures in this evolution. The authors suggest that there used to be four different terms for grandparents in the proto-Pama-Nyungan language family, which was supported by the data. The results show no evidence of co-evolution between these grandparent systems with neither community marriage organization nor post-marital residence. There is not a significant correlation between grandparent and cross-cousin terms; however, there is some evidence that grand-child terms are correlated to grandparent systems.

This article examines variation in kinship terminology. The authors develop a new typology of kinds of kinship terminologies, and they propose that terminologies will distinguish siblings of the same and opposite gender when there is a cultural emphasis on cross-sex relations. Empirical analysis supports that a prolonged post-partum sex taboo (rather than sibling avoidance) predicts the presence of a primary cross-parallel component in sibling terminology.

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.

The authors review and provide an alternative to Levi-Strauss's theory on unilateral cross-cousin marriage. Levi-Strauss theorized that matrilateral cross-cousin marriage (males marrying their maternal uncles' daughters) occurs more than the patrilateral form because the former promotes more "roundabout" woman-giving and overall social solidarity. He also states that the form of cross-cousin marriage does not depend on kinship linearity. In contrast, the present authors hypothesize that, among societies with unilateral cross-cousin marriage, patrilineal societies will have matrilateral cross-cousin marriage and matrilineal societies will have the patrilateral form. To justify their prediction, the authors point to the close, informal relationships fostered between males and their maternal uncles in patrilineal societies and between males and their paternal aunts in matrilineal societies.
