This article focuses on the effect of environmental extremes and unpredictability on human behavior and reproductive strategies. Significant correlations were found between environmental extremes and unpredictability and several variables, including mobility, subsistence mode, and degree of polygyny.

This article focuses on ecological correlates of sexual division in the control of resources. The author tests several ecological theories put forth by others. Sex coalitions are examined in humans, and sexual dimorphism in resource acquisition and control is discussed.

This article seeks to examine the distribution and frequency of bride-theft. Tylor's (1889) findings between various forms of marriage by capture and certain other social instituions are confirmed.

This article examines cooking strategies and cooking containers cross-culturally. Focusing on stone boiling and direct fire cooking, the authors find that geographic location and climate (particularly temperature, rainfall, and evapotranspiration) will be associated with cooking strategy. Container fabric type was also examined, and was found to be associated with cooking strategy, climatic variables, and subsistence type.

This article offers a behavioral ecological approach to the study of child training practicies. Gender differences in child training are discussed in light of evolutionary theory, and the author suggests training is likely tailored to promote the reproductive success of each gender. Generally, boys are trained to be more aggressive, stronger, and self-reliant; girls are trained to be more hard-working, responsible, obedient, and sexually restrained. Gender differences in child training frequently vary with degree of polygyny and/or social stratification in a society.
