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 investigates the relationship between Crow kinship terminology and avunculocality. Results indicate that if matrilateral cross-cousin marriage is associated with Crow kinship systems, then societies that are avunculocal are more likely have Crow systems.

This study tests a common theory that predicts a positive relationship between exogamy and cross-allegiances between social units. Results did not support this prediction. Cross-allegiances were only weakly related to cross-cousin marriage.

Researchers examined kinships terminology systems for explanations regarding specifically observed typology of kin terms for cousins cross-culturally. They explore two theories, the first relating to population size via bottleneck evolution, and the second relating to social practices that shape kinship systems. Using the Ethnographic Atlas within D-PLACE, 936 societies with kinship system information were studied. The findings did not suggest a relationship between increased community size and a decrease in kinship complexity, however the research does suggest a relationship between practices of marriage and descent and kinship complexity.

This article uses alliance theory and kin selection theory to examine the relationship between consanguineous marriage and descent system. The author argues that there is no relationship between the severity of incest taboos and the rules of exogamy or endogamy. A series of testable hypotheses regarding incest, marital, and descent rules are presented.

The authors investigate environmental reasons for cross-cultural variation in the permissibility of cousin marriages. In particular, they test whether higher levels of pathogen prevalence and geographic isolation increase the likelihood that cousin marriage will be allowed. The authors' underlying theory is that cousin marriages provide protective homozygosity against some pathogens and provide more options when mate choices are limited.

How have ethnopolitical landscapes transformed across Africa? The authors of this article analyze how ethnic identities have been influenced by two major socioeconomic revolutions of 19th and 20th century sub-Saharan Africa: cash crops and print technologies. They found that ethnic identities, through the means of politicization and boundary-making, had become more salient and politically relevant in communities where cash crops and print technologies were present. Furthermore, areas with cash crops and subsequent agricultural zones were found to have stricter ethnic boundaries and less interethnic marriage than areas with more print publications.

This article tests the conflicting loyalties theory that predicts feuding will be absent when multiple allegiances are present. The author tests this theory using variables that are believed to establish cross-cutting loyalties, such as exogamy and cousin marriage. Several hypotheses are tested, none are supported.

Author proposes and presents evidence in support of the theory that most societies practice virilocal or patrilocal residence (this is the "normal" pattern" and that matrilocal residence is adopted when societies migrate to an already populated area.

This paper tests some of Levi-Strauss's pronouncements on Crow-Omaha kinship systems cross-culturally. The author tests the relationships between Crow-Omaha and Hawaiian kinship systems and cross-cousin marriage. Results suggest that both kinship systems will prohibit cross-cousin marriage.
