This study uses logistic regression to test the relationship between homosexuality and ecological and psychosocial variables. Significant associations were found between the frequency of homosexuality and type of agriculture, the occurrence of gathering, and psychosocial stressors in women's lives.

This study attempted to replicate earlier findings regarding population structure and teen pregnancy rates. Findings support the previous predictions that sex ratio, economic development, and latitude are all inversely related to teen birth rates.

In this article, the authors seek to test the theory that the veiling of women is a form of male mate guarding strategy, especially in harsh environments (specifically those with poor health and high mortality). They test this hypothesis using survey data drawn from 25 majority Muslim countries. This theory found support in the results of their statistical tests. In addition to testing the hypotheses articulated in the paper (as noted above), they also ran correlations between income level, importance of religion, and a countries sex ratio and views on the importance of veiling.

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 article discusses the variation in sex ratios at birth among human populations and the possible explanations for this variation. One possible explanation is the timing of intercourse and its relationship to the frequency of intercourse, which can affect the timing of conception. The article presents evidence that the male/female sex ratios of 148 countries declined with total fertility rates and polygyny intensity and increased with contraception use in correlational analysis. These results were independent of mother's age and level of economic development. The predictive effect of polygyny and contraception disappeared when total fertility was added to the equation. The article also considers other possible explanations for the variation in sex ratios, such as genetics, hormones, nutrition, and social factors.

The present study attempts to replicate the Barber (2011) finding that more considerable security influences a country's disbelief in God. However, this research uses a more diverse sample and seeks to answer additional questions about religiosity and security than the previous work. The results are in line with all of the predictions and offer extra support to the uncertainty hypothesis.
