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 is mainly concerned with understanding the motivators toward egalitarianism through modeling via a game that combined elements from both hawk-dove and prisoners dilemma. While most of the article is focused on this model, the researchers also tested their hypotheses cross-culturally on a sample of forager societies. In both cases, they found evidence that the benefits of cooperation drove egalitarianism.

This book investigates individual and group responses to death and the problems that death can create in a society. Several hypotheses regarding grief and mourning, as well as their variation with other societal variables, are supported with cross-cultural tests.

Focusing on cultures of New Guinea, this article tests the relationship between subsistence type and various indicators of cultural complexity: population density, settlement size, and residential permanency. Subsistence type is examined through dependence on aquatic resources--specifically, the consumption of aquatic fauna. Relevance of social and political history of the region is also examined.

This article empirically examines Levi-Strauss’ (1966) theory on cannibalism, that “an analysis of cooking [and by extension cannibalism] as a language will reveal certain structural oppositions in society” (54). Theoretical and methodological weaknesses indicate cooking may not be analogous to language and therefore linguistic theory is not applicable for the analysis of cannibalism.

Authors explore the relationship between privacy among newlywed couples and romantic love as a basis for marriage. Authors also consider the relationship between newlywed privacy and kin avoidence. Both associations are found to be statistically significant.

This article explores the relationship between marital residence and romantic love; results suggest that romantic love is most important in societies with non-neolocal marital residence. The author explores potential functions of romantic love, including bolstering against the divisive pressure of relatives, or to substitute for economic interdependence between spouses.

This study examines the consequences of birth order; results suggest that the firstborn child is more likely to have social authority as they grow older (they have siblings’ respect, they control property or head kin groups, etc.). The authors suggest that this authority may be legitimated by extra attention firstborns receive though elaborate birth ceremonies and teknonymy.

This article investigates several correlates of freedom of choice of spouse, including general male-female contact and antagonism in premarital male-female interaction. Particular attention is paid to dances in the role of making contact with a spouse.
