Using data on 25 ethnolinguistic groups in the Austronesian language family, this study asks: does cooperation in games vary with socio-ecological differences across cultural groups? The authors suggest that cultural groups that cooperate in subsistence, tend to have intergroup conflict and less intragroup conflict, and are less socially stratified are more likely to play cooperative games compared to other groups. While the results support the first three hypotheses, there is insufficient data to support the fourth. The authors conclude that games serve as training ground for group norms and values.

Researchers investigated the variation of land tenure systems across forager societies using the economic defensibility model. The study attempted to explain the variation in tenure systems across 30 hunter-gatherer societies. Using data on defense and sharing of resources among groups, and indicators of resource density, resource predictability, and competition for resources, the researchers were unable to explain the variation. This study highlights the vast range of diversity and complexity of foragers subsistence strategies, and proposes that it may be more telling to conceptualize tenure systems among hunter-gatherer societies as assemblages of multiple property regimes. While there was no overall evidence that environmental variables of resource density and predictability explain variation in tenure systems, researchers did find that increasing population density, and greater competition for resources leads to greater territoriality.

This article investigates peer relations in infancy, both in primates and in preindustrial human societies. Data from these populations shows a strong tendency toward a multi-age composition of play groups rather than solely peer-aged play groups for infants. Patterns in child care across societies of different subsistence types are empirically examined.

The purpose of this paper is to analyze thesubsistence activities of the Kung Bushmen. These activities are then used as a benchmark for comparing other hunting and gathering societies. A cross-cultural analysis asks: To what extent are the Bushmen typeical of hunter-gatherers in general? Finding suggets that, as a less reliable subsistence source, hunting is only used as the primarily subsistence strategy when there is no alternative viable subsistence strategy. Findings also suggest that hunting is the dominant mode of subsistence only in the highest latitudes.

In this article, the authors seek to understand the predictors of land privatization by empirically testing defendability and resource stress theory. By drawing on previous research they are able to test these theories in more expansive and nuanced ways. They conclude that they have found strong support for defendability theory.

In this study, the authors analyze subsistence economies to better understand their variability and success, the role of the environment in different subsistence choices, and the relevance of fishing, specifically in mixed economies. They find regular subsistence patterns, suggesting that not all subsistence combinations are successful. Their findings also indicate that environment influences subsistence choice, mixed economies are common, and that fishing plays a key role in mixed economies.
