This study focuses on predictors of divorce, cross-culturally. Variables measuring infidelity, infertility, personality, economy, kin, absence, health, ritual and politics are tested. An evolutionary/adaptionist approach is found to be most useful in explaining the nature of conjugal dissolution cross-culturally.

This article uses a Darwinian approach, predicting that hierarchies persist and increase in social evolution because they increase fitness for individuals at higher levels within the hierarchy who choose to further social assymetry and benefit their fitness at the expense of the greater group. Polygyny is used as the indicator of fitness. Correlations tested support the hypothesis.

This study examined the relationship between market integration and generalized prosocial behavior. The authors review theory suggesting that market integration fosters cooperation and fairness in dealing with strangers, and they investigate whether child training for generosity, honesty, and trust are associated with level of market integration among societies in the Standard Cross-Cultural Sample. Results do not indicate an association.

Aiming to better understand human demographic and dispersal history, the study uses Bayesian phylogenetic comparative methods to trace post-marital residence and cultural changes among 27 Indo-European and 135 Austronesian languages. They suggest that changes from uxorilocality to other types of residences (neolocality and virolocality) are more common than the inverse transitions. The results are generally supported with one exception: Austronesian societies have a higher rate of transition from neolocality to uxorilocality (1.5) than the other way around (0.9). Other relevant findings are that proto-Indo-European societies tend to follow virilocality, while proto-Malayo-Polynesian uxorilocality. There is a commonality for both language families to present instability of uxorilocality and unusual loss of uxorilocality.

This study develops a model of the conditions under which a societies switch from a anarchy to a hierarchy. Empirical results suggest that the presence of police, technological sophistication, population density, and food storage are positively associated with the presence of a territorial hierarchy.

The present study aims to evaluate correlations of private property from two of Murdock's datasets, one of 147 societies (1981) and the other of 312 societies (1967). Altogether the author tested 146 variables coded by Murdock against variables regarding the ownership of land and of movables drawn from Murdock (1967), Simmons (1937), and Swanson (1960). In total, there were 51 statistically significant correlations between private property ownership and other variables. Additionally, the author summarizes the results from this article and the two that preceded it stating that throughout all of the correlations he ran, the practice of agriculture, the use of cereal grains, and the presence of castes and classes were the only variables that predicted private property in all of the datasets that were utilized.
