This study uses evolutionary theory to hypothesize about the association between age, gender, and gambling. Results suggest that males are more frequent and riskier gamblers than females and that young adults are more likely to have gambling problems than people of other age classes.

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 paper investigates two theories of social stratification: Lenski’s ecological-evolutionary taxonomy which is based on subsistence technology and Service’s taxonomy which is based on social organization. Findings indicate that different components of stratification are better explained by Lenski’s taxonomy, but a global concept of stratification matched better with the Service taxonomy.
