The author expands on the findings of Barry, Bacon, and Child (1959), hypothesizing that type of environment is an intervening variable in the relationship between subsistence type and child training. A multiple classification analysis is used.

The purpose of this book is to introduce a conceptual and methodological perspective called the "universalist approach," and to use this approach in exploring the pancultural antecedents and affects of parental acceptance-rejection of children,

This paper reviews the results of the author's cross-cultural studies of war and aggression and their implications for prehistory.

This article discusses the relationship between child training and certain variables, such as economy.

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 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 study tests the weaning food availability hypothesis, that both the introduction of foods other than breastmilk and the cessation of breastfeeding will vary by society's subsistence type. This hypothesis has implications for demography, as accelerated weaning can lead to increases in both mothers' fertility (due to decreased birth intervals) and infant mortality (due to the presence of pathogens in new foods).

This article examines differences in parental preference of potential in-laws across cultures. Results suggest that parents look for traits that will benefit themselves and their kin and that gender and subsistence type affects the traits that parents deem most important.

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 article investigates how status of the elderly is affected by economic type, family organization, inheritance of real property, and unilocal residence patterns. Multivariate analysis ultimately suggests that agricultural economy, patrilocal residence, and fully extended family systems are significant predictors of higher status of the elderly. No major gender differences were discovered.
