The researchers operationalize new measures of Socially Imposed Monogamy (SIM) and Ecologically Imposed Monogamy (EIM) using scores from Murdock's (1986) Ethnographic Atlas in order to reevaluate Alexander et al.'s (1979) findings that sexual stature dimorphism is higher in SIM (monogamous and highly stratified) and polygynous societies compared to EIM (monogamous and egalitarian) ones. The expected associations between marriage system and sexual dimorphism are not robustly significant; however, an interaction effect is discovered between marriage system and stratification with regard to dimorphism.

This article explores the relationship between sexual dimorphism of stature and variables of marriage, diet, subsistence and environment. Significant associations were found between security and plentifulness of food supply, protein availability, and sexual dimorphism of stature.

This study re-examines the hypotheses offered by Kleiman (1977) linking monogamy in humans to monogamy in other animals. Of seven hypotheses, only two were weakly supported when using a cross-cultural analysis.

This article examines the relationship between sexual dimorphism of stature and latitude; data support the association. The authors also find support for an association between latitude and human marriage systems, a variable proposed by Alexander (1979) to explain variation in sexual dimorphism of stature. When societies are categorized by latitude, the relationships between marriage systems and sexual dimorphism do not reach significance. Overall the authors emphasize the influence of environmental adaptation on sexual dimorphism rather than an explanation solely focused on male-male competition.

This study tests the validity of two previous diachronic studies examining the relationship between subsistence strategy and sexual dimorphism of stature with synchronic data. The authors find that neither hypothesis is valid.

This article examines height and sexual dimorphism of stature from a sociobiological perspective. Diet, child rearing, and marriage practices are tested as possible factors contributing to height sexual dimorphism of stature. Results provide some support for a nutritional hypotheses, but sexual selection and parental investment are not statistically significant.

This article presents a phylogenetic approach to studying sexual dimorphism of stature. Results show a significant association between sexual division of labor and sexual dimorphism of stature.

This chapter examines the role of male and female ornamentation. Several hypotheses concerning mating systems and ornamentation are empirically tested; several are supported.

The present study examines the effect of social status on stature sexual dimorphism and whether food security acts as a mediator for this relationship. In societies where females have high social status and can exercise mate choice, there is lower stature sexual dimorphism. Food security enhances these results. Conversely, there is greater stature sexual dimorphism in societies where females have low social status and cannot exercise mate choice, especially if there is food insecurity.

This article suggests that Wilson's definition of sociobiology, which incorporates underlying principles of animal social behavior, can be applied to human bahvior. Specifically, Wilson's assertion that the major ecological conditions associated with monogamy in animal societies, is tested on human societies.
