The second and third parts of this book classify the economic systems of foraging and agricultural societies in the SCCS based on correlations between their institutions of property an distribution. These economic types are then examined for relationships with other social, political, demographic, and environmental factors in order to draw tentative conclusions regarding the origins of the Agricultural and Industrial Revolutions. The fourth part of the book uses cross-national data to examine similar associations in industrial/service economies, and is not included here.

This study tests possible explanations for sexual dimorphism in human post-reproductive life-spans. The author focuses on explanations involving male paternal investment and finds that men in agricultural societies are more likely to invest in their offspring than men in hunter-gatherer societies.

This paper proposes that marriage transactions are mechanisms by which households meet labor needs, distribute property, and maintain or enhance status. The authors find that type of marriage transaction is related to subsistence type and social stratification. In particular, bridewealth is more common where property is limited while dowry is more common among property-owning classes.

This article tests several hypotheses related to the presence or absence of polygyny. Results suggest a negative relationship between polygyny and male provisioning, and positive relationships between polygyny and warfare, interpersonal aggression, and pathogen stress.

This article offers an exploratory study of the structural and psychological influences related co-wife conflict and cooperation.

This article uses factor analysis to identify the key variables underlying the many cross-cultural associations reported by Textor (1967). Twelve factors are identified.

This study examines the relationship between sexual division of labor and social organization variables. Results suggest relationships between both mode of marriage and polygamy and female contribution to subsistence.

This exploratory study seeks to explain cassava production and processing in Africa by considering cultural, agronomic, and environmental data. After examining the descriptive results of the agricultural and social contexts of cassava use, the authors build upon Boserup's population density model (1965) to analyze their own hypothesized model of cassava's importance among the sampled societies.

This article investigates the determinants of post marital residence, particularly female contribution to subsistence. This study suggests in contrast to previous research that female contribution to subsistence does predict residence if non-sororal polygyny, and internal warfare are controlled. Theoretical perspectives on how marriage system affects the relationship between residence and contribution to subsistence are discussed.

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.
