This article investigates residence, descent rules, and family structure. Empirical analysis suggests that they are associated with settlement patterns, particularly economic and demographic variables.

Research sampled 143 societies from the Standard Cross Cultural Sample to test the relationship between honor culture, social rewards for warriors, and intergroup conflicts. Using mediation analysis based on multiple regression, and structural equation modeling, the research supported the theory that honor culture was positively associated with intergroup conflict, and that this relationship was mediated by social rewards for warriors.

Using a self selected sample of 33 ex British colonies and the Ethnic Power Relations database, the author sampled 170 ethnic groups from Africa, Asia, and the Middle East to test for association between precolonial state formation, colonial state building tactics, and modern ethnic conflicts. The author theorized that ethnic groups that were centrally governed before the colonial period were less likely to be recruited to colonial security forces, leaving them out of the picture during the formation of the independence movement and the formation of a post-colonial regime. This in turn is theorized to lead to greater contemporary armed conflict against the regime from which they were excluded.

Researchers examine the body of literature on the practice of geophagy(the consumption of earth), shining a light on the harms, benefits, and proposed reasoning behind the practice cross-sectionally. In addition to this review of the literature, gaps in the literature and suggestions for future research are discussed.

The authors of this article evaluate how the legacies of early statehood (i.e., precolonial centralized ethnic groups) in Africa continue to impact democratic governance. They find a positive relationship between early states and support for autocratic rule, especially in former British colonies that were highly centralized prior to colonization. They suggest that the transmission of political and cultural norms play an important role in the support for autocracies.

The biological success derived from cumulative culture and cooperation and their association with ancestral group structure is examined. It is suggested that inclusive fitness cannot explain extensive cooperation in hunter-gatherers because in most of the foraging societies examined, most individuals in residential groups are unrelated. These large social networks may explain why humans are capable of social learning.

Researchers examine the ethnographic record, sampling 82 hunter gatherer societies from the HRAF World Cultures database, for cross-cultural patterns of archaeological evidence of knowledge of astronomy and constellations. Surveying the data, researchers identified many patterns in the upper paleolithic, noting the importance of further examination of this topic.

Do tropical hunter-gatherers follow the diet known today as the Paleo diet? Using nutritional data on 11 tropical hunter-gatherer groups, this study asses dietary composition. The results show that there are high levels of variation in the distribution of protein, fat, and carbohydrates among the sample of 11 hunter-gatherer groups.

A materialist approach is used to study the status of women in hunter-gatherer groups. Techno-ecological factors are tested as predictors of women's status.

This study re-examines the hypotheses offered by Kleiman (1977) linking monogamy in humans to monogamy in other animals. Of seven hypotheses, only two were weakly supported when using a cross-cultural analysis.
