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 presents a phylogenetic approach to the work of Hartung (1982) on the relationship between inheritance and marriage patterns. Results indicate that polygyny is associated with male-biased inheritance.

This article investigates the sexual division of labor between adults and children.

Thus, women tend to benefit more from children’s labor.
