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.

The researchers utilize a GIS approach in order to examine the relationship between global linguistic distribution and various cultural and environmental factors. The resulting positive association between political complexity and both latitude and language range leads the researchers to propose that large, politically complex entities exert a homogenizing pressure on language. However, the causal link may also be in the other direction, with possession of common language facilitating the creation of more complex political institutions.

This paper examines two measures of cultural complexity: Carneiro’s (1970) scale and codes assembled at the University of Pittsburg. Analysis suggests the two measures are compatible, thus providing evidence for their validity. The authors assess the usefulness of a cultural complexity scale by testing the relationship between descent rules and cultural complexity. Significant associations suggest that cultural complexity is related to social organization and is thereby a useful measure.

This article examines the relationship between social structures and sexual jealousy. Results suggest that social structures that emphasize the importance of pair-bonding, progeny, personal property, and exclusive marital sex relations are associated with sexual jealousy in males.

This paper examines the relationship between the complexity of a society's material culture and its development of cognitive technologies for numeration and timekeeping. The researcher claims that the resulting positive correlation between these variables as support for a theory of material culture as 'scaffolding' for number concepts, providing tangible, shareable, manipulable forms for abstract numerical constructions.

Researchers tackle the moral gods hypothesis which proposes that moral gods enabled large-scale societies to evolve. They use 414 societies spanning 10,000 years in Seshat: Global History Databank and code 51 measures of social complexity and four measures of moral gods. The findings of the present study challenge the moral gods hypothesis. In the societies studied, complex societies appear to precede moral gods rather than the inverse of moral gods preceding complex societies.
