This study examines different sources of marital stability. Authors find that subsistence dependence between partners provides marital stability and where subsistence dependence is not important, romantic love substitutes as a source of marriage stability.

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 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.

This study examines the relationship between satisfaction of early oral and dependence needs and concern with affection in adulthood. Data showed significant support for an association between the satisfaction of early oral needs (but not the satisfaction of dependence needs) and concern for affection in adulthood.

Based on work by Rosenblatt (1966), this article tests a hypothesis relating sexual freedom to romantic love. Findings suggest a relationship between premarital and extramarital sexual permissiveness equality for women and men and romantic love.

This paper proposes that marriage transactions are mechanisms by which households meet labor needs, distribute property, and maintain or enhance status. The authors find that type of marriage transaction is related to subsistence type and social stratification. In particular, bridewealth is more common where property is limited while dowry is more common among property-owning classes.

This article examines the relationships between family structure, type of mate-selection system, and romantic love as a basis for mate-selection. Analysis indicates that autonomous mate selection is more common in societies with nuclear family structure and neolocal residence patterns. Romantic love as a basis for mate selection is also more common with nuclear family organization, but it is negatively associated with neolocal residence patterns.

This paper presents research on the factors that promote romantic love as a basis for marriage in non-industrial societies. After a discussion of the previous literature on romantic love in ethnographic societies, the authors used the SCCS, EA, and data from eHRAF to create a data set of 109 cultures and then utilized multiple ordinal regression to test the relationship between different types of families and post-marital residence practices and the importance of romantic love in marriage. The findings show that monogamy is significantly correlated with romantic love, while nuclear family organization and neolocal post-marital residence are not significantly correlated. The presence of polygyny is found to lower the probability of romantic love being a basis for marriage. These findings contradict previous research, which found a relationship between non-neolocal post-marital residence and the presence of romantic love in marriage.

Using a cross-cultural sample of 91 societies, this paper draws on ecological theory to test if unpredictable environments will favor subsistence diversification. The general hypothesis is that societies with high climate unpredictability and resource stress would exhibit more subsistence diversity than societies in more stable climates. The authors examined four environmental and resource stress variables while controlling for temperature variance, subsistence activity, and phylogeny. Support was found for 2 of the 4 variables--chronic scarcity and environmental instability. In the discussion they suggest that more commonly observed events (e.g. annual hunger and climate unpredictability) may give people more motivation to change subsistence than rarer events (e.g. natural hazards and famine).

This article presents a phylogenetic approach to studying sexual dimorphism of stature. Results show a significant association between sexual division of labor and sexual dimorphism of stature.
