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.

Focusing on 61 preindustrial societies that have information on fertility, the author asks what factors may explain variation in fertility, what devices are used to control fertility, and whether differences in fertility appear to be in line with the societies' environments.

Does a woman’s age predict her preferences for an ideal partner? Through a cross-cultural study of heterosexual women ages 18-67 from 147 countries, the authors of this article find that age has a negligible effect on a woman’s partner preferences in general. However, they do find some relationships between age and specific preferences, such as confidence-assertiveness, intention to be a parent, and the age range deemed acceptable for a partner.

This study investigates responses to childlessness in a cross-cultural sample. Solutions to childlessness appear universal, and magico-religious-ethnomedical solutions seem the most likely to be tried first. Empirical analysis also shows that women are blamed for childlessness more often than men, which the authors suggest could be due to women’s lower status.
