This study explores predictors of variation in two dimensions of marital residence patterns among hunter-gatherers: 1) the tendency toward patrilocality versus matrilocality and 2) the tendency toward unilocality versus bilocality.

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

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 tests some conditions that may lead to the emergence of unilineal descent, focusing on unilocality and warfare. Unilineal descent is thought to be likely in a unilocal society without a centralized political system that is experiencing intra- or inter-societal warfare. The authors also posit that a "clan" system usually develops prior to a "lineage" system.

This article examines resource problems and warfare in a sample of societies from eastern Africa. The frequency and predictability of resource problems are examined, as are two other dimensions of warfare: resource-taking and commission of atrocities. Differences between state and nonstate societies, as well as pacified and non-pacified societies, are also examined and shown to affect associations between resource and warfare variables.

This article reexamines Coppinger and Rosenblatt’s (1968) finding that romantic love insures marital stability where there is low subsistence dependence between the spouses. Analysis suggests that Coppinger and Rosenblatt’s associated variables, romantic love and subsistence dependence, are only related through their common association with subsistence technology.

This study tests the common belief that hunter-gatherers suffer more famine than other subsistence types. Controlling for habitat quality, authors examine the relationship between famine and subsistence type and find that hunter-gatherers actually experience significantly less famine than other subsistence types.

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.

This article presents theory and hypothesis tests that suggest that the decline of women's contribution to intensive agriculture is related to increases in fertility and domestic work associated with cereal crops. Additionally, men in agricultural societies are less likely to invest time in hunting and warfare, so their contribution of agricultural labor relative to women's increases.

This paper investigates the relationship between marital residence and warfare. The author evaluates two theories proposing opposite causalities: one, that internal warfarecauses patrilocality; the other, that residence comes first and influences type of warfare. The author presents a new model emphasizing the role of population size in determining type of warfare, which in turn affects marital residence. However, the role of migration in determining marital residence is also considered.
