This article presents a reanalysis of a study by Ember (1978) examining the predictors of men's heterosexual fear. The author finds that Ember's model is not upheld and presents a new model of men's heterosexual fear using path analysis. Results suggest that mother-child sleeping arrangements and food shortage are directly related to men's heterosexual fear.

This article discusses two different explanations of male initiation ceremonies. Evidence is also presented that suggests that psychological conflict might strongly predict male initiation in the presence of the following catalysts: nonmatrilocal residence, nonstate political organization, and warfare.

This article presents theory and hypothesis tests that suggest that the decline of women's contribution to intensive agriculture is related to increases in fertility and domestic work associated with cereal crops. Additionally, men in agricultural societies are less likely to invest time in hunting and warfare, so their contribution of agricultural labor relative to women's increases.

This paper reviews the results of the author's cross-cultural studies of war and aggression and their implications for prehistory.

This article examines correlates of sexual fear among men and women. The author concludes that the more authority men have over women, the more women will dread male genitals and vice versa.

This article presents two evolutionary models that may explain relationships between war and socialization of children: the "environmentally contingent reproductive strategy" (ECRS) model put forward by Draper and Harpending (1982), and a model put forward by Carol and Melvin Ember. Results do not provide support for the hypotheses involving father-infant sleeping proximity derived from the ECRS model. The authors also find some inconsistencies with their own model.
