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 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.

Using a sample of 60 societies from eHRAF, this study explores the cross-cultural commonalities and differences in human-pet dynamics. The authors focus on understanding the range of functions of pets and the positive or negative treatment of pets. In addition, they test whether human investment in pets is a significant challenge of evolutionary theory. First, the results support that there are distinct functions of pets, challenging the common view of contemporary function of pets as emotional surrogates. Secondly, the data collected show an ambivalent treatment of pets across cultures, including small-scale societies. Finally, the research does not support the idea that human investment in pets sacrifices their reproductive success.

This study tests the hypotheses that games of strategy will be more prevalent in societies where political power is based on a "network strategy" and that network societies place more value on the enculturation of obedience in children. Both hypotheses are supported.

This paper investigates the presence of gambling in preindustrial societies. Analysis shows that the presence of gambling can be predicted by region, the presence of domestic commercial money, socioeconomic inequality, and mobility combined with food supply from animal husbandry. The author suggests that the ideas underlying the Friedman-Savage utility function (1984) can be helpful in making predictions about which precapitalist societies do and which do not engage in gambling.

Textor summarizes cross-cultural findings on societies where subsistence is primarily by 'food gathering' which includes hunting, fishing, and gathering.
