The authors develop and empirically test a model in which exogamy is negatively predicted by community size, due to decreasing heterogeneity from endogenous marriages in small settlements, and positively predicted by disparity in productivity between communities which is 'smoothed out' by transfer of community members through exogamous marriages. Support for both predictions is found, which is used to argue that cultural traits like marriage customs are heavily influenced by population-environment relationships.

This article presents a theory of evolutionary development of incest regulation, namely that as societal complexity increases the incest taboo will become less extensive. The author presents empirical support for this theory, though the association is not supported among simply structured societies. The role of descent type is also discussed.

This article takes a materialist approach to the evolution of ideology in human culture.This article examines the possible coevolution of sociocultural subsystems. The author emphasizes ideological variables and their relationship to technological and social-structural subsystems. Analysis supports a process of coevolution, which the author suggests refutes broad claims of cultural particularism.

Thi study tests a hypothesis on the relationship between frequency of warfare and sociocultural development.

This paper is an investigation into the relationship between social differentiation as a proxy for societal 'development' and various categories of crime. A positive relationship is interpreted by the author as empirical cross-cultural support for Durkheim's theory that these two factors will increase together as parallel processes of 'sociocultural evolution'.

This study is a reexamination of Bacon's (1965) previous cross-cultural study regarding drinking. The current study supports the dependency-conflict hypothesis that frequency of drunkenness is related to dependency needs in childhood and adulthood.

Female aggression, reasons and targets of that aggression are described using a cross-cultural sample. It is suggested that female aggression is often a means of competing for men or subsistence products, but it also may be a means of defense.

Causal factors to the development of crime are examined. Frequency of theft and personal crime are tested against these causal factors in a search for correlations.

Textor's (1967) A Cross-Cultural Summary is used to test a variety of Sauer's (1952) hypotheses concerning the sequence of agricultural developments. Tests are primarily focused on subsistence variables.

A study of the relationship between older women and their young female kin. Relationships between women's relationships with their mother-in-laws and subsistence contribution, residence, descent, and food preparation are examined. Findings offer significant support for patterns in the relationship between older women and younger female kin.
