The authors predict that fitness outcomes will be negatively associated with spousal relatedness among foragers but positively associated among non-foragers, due to the greater social benefits of intensive kinship systems among non-foragers. Support is found for this hypothesis; however, an interaction effect is discovered with inbreeding, which appears to account for the variability in these relationships independent of subsistence activity. The authors qualify this support in order to explain why the incidence of cousin-marriage in non-foraging societies is not higher.

This article investigates incest rules, proposing that they are instituted by rulers as a way of preventing wealth-concentration among non-ruling families. Three hypotheses are derived and supported with empirical analysis. Two alternative evolutionary hypotheses are discussed and dismissed by the author.

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 book examines male and female power in various kinship configurations. Variables for male dominance and female autonomy are associated with various political and social variables, such as political complexity and co-wife jealousy. Several hypotheses are supported.

This article challenges common assumptions about hunter-gatherers and demonstrates that previous ideas about residence, division of labor and warfare are not supported by the cross-cultural data.
