This article uses signaling theory and tests for a relationship between costly male rites and frequency of warfare.

This study explores the extent to which heterosexual sex, love, and intimacy are interrelated and the degree to which the sexual revolution has had a positive or negative impact on male-female relationships. The author employs a correlation matrix to examine the interrelationships of several variables related to aloofness and intimacy in the sexual and non-sexual aspects of heterosexual relationships. Results suggest that the sexual revolution has had some positive effects on male-female relationships, but also that sexual behavior does not predict the degree to which marriages are intimate or aloof. Results also show little support for the hypothesis that marital aloofness is related to hypermasculinity.

The researcher predicts a positive association between prevalence of homosexuality and agricultural and pastoral subsistence types, reasoning that higher frequency of arranged marriages among agropastoral societies will lessen negative selection pressure on genes which encode for non-exclusive heterosexual orientation. Findings appear to support the prediction.
