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 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.

Using a sample of 145 African societies, the authors seek to examine the relationship between segmentary lineage organization and conflict. Presented is evidence supporting the claim that segmentary lineage societies are more prone to conflict and to conflicts larger in scale and duration. The authors aim to contribute to a better understanding of the determinants of conflict, and additionally address the applicability of the present study beyond Africa.

This study examines predictors of the type of conflict management used at the community level. Results suggest that level of political integration is associated with mode of conflict management.

This article examines how an increase in overall societal complexity affects local political offices. Findings suggest that a more complex society has a slight tendency to develop more political offices within the community, but there is greater support for an increased number of jurisdictional levels within the community.

This study investigates the presence of feuding, arguing that a solely evolutionary or functional approach misses important inter-societal factors. Results indicate that while fraternal interest groups are associated with feuding, the presence of war and level of political integration also increase the likelihood of feuding.
