  1. Risk of resource failure and toolkit variation in small-scale farmers and herdersCollard, Mark - PloS one, 2012 - 1 Hypotheses

    Prior research by Oswalt (1973, 1976) and Torrence (1983, 2001) has suggested that risk of resource failure is a significant predictor of toolkit complexity and diversity among hunter-gatherers. In this paper, the same relationship is tested among small-scale herding and farming groups. However, no significant correlation is discovered between any measure of resource risk and any measure of toolkit complexity. The researchers suggest that this absence may be the result of greater reliance on non-technological diversification methods among farmers (i.e. spatial diversification, mixed farming, intercropping), or of other unaccounted-for sources of risk (i.e. intergroup raiding and warfare).

  2. Risk, mobility or population size?: Drivers of technological richness among contact-period western North American huntergatherersCollard, Mark - Philosophical Transactions of The Royal Society B., 2013 - 3 Hypotheses

    This paper builds off previous research into the effect of population size and resource risk on complexity of subsistence technology by investigating the relationship between these independent variables and total number of material items and techniques used by various western North American hunter-gatherer groups. This tally of total technological complexity is found to be insignificantly related to population size or residential mobility; however, there is a significant correlation in the expected direction between technological complexity and one measure of resource risk (mean annual temperature during driest month). Tying this finding to previous analyses of subsistence technologies, the authors theorize that environmental risk is a pervasive driver of technological ingenuity and cultural evolution.

  3. Population size and cultural evolution in nonindustrial food-producing societiesCollard, Mark - PLOS ONE, 2013 - 1 Hypotheses

    Seeking to resolve contradictions between previous studies, these authors conduct empirical analysis on the relationship between population size and cultural evolution. Results indicate that population size influences toolkit richness and complexity, even when proxies for risk of resource failure are introduced in the regression model. Authors speculate that the association is weaker for hunter-gatherers because those societies are more affected by risk of resource failure and have institutions that facilitate cultural evolution despite smaller population size. There also may be a threshold effect in the influence of population size on toolkit structure.

  4. Population size as an explanation for patterns in the paleolithic archaeological record: more caution is neededCollard, Mark - Current Anthropology, 2013 - 1 Hypotheses

    Previous studies have yielded contradictory results on the relationship between population size and cultural evolution. Focusing on tool complexity these authors introduce the risk of resource failure as a possible confounding variable. They conclude that population does not predict tool kit complexity when controlling on other factors. There were significant correlations between tool kit complexity and some of the resource measures.

  5. Causes of toolkit variation among hunter-gatherers: a test of four competing hypothesesCollard, Mark - Canadian Journal of Archaeology, 2005 - 4 Hypotheses

    This study tests four hypotheses that propose potential environmental and social predictors of toolkit size and complexity among hunter-gatherers. Hypotheses predicting relationships between population size, residential mobility, type of food resources and toolkit structure are not supported. Risk of resource failure is the only variable that is significantly associated with toolkit structure.

  6. Technological organization and settlement mobility: an ethnographic examinationShott, Michael - Journal of Anthropological Research, 1986 - 2 Hypotheses

    This study tests the relationship between mobility and technology among foragers, with the intent of applying findings to the archaeological record. In data analysis, mobility frequency is differentiated from mobility magnitude, and technological diversity is differentiated from technological complexity. Results suggest that mobility frequency is negatively associated with technological diversity while mobility magnitude is negatively associated with technological complexity.

  7. Cassava production and processing in a cross-cultural sample of african societiesRomanoff, Steven - Behavior Science Research, 1992 - 12 Hypotheses

    This exploratory study seeks to explain cassava production and processing in Africa by considering cultural, agronomic, and environmental data. After examining the descriptive results of the agricultural and social contexts of cassava use, the authors build upon Boserup's population density model (1965) to analyze their own hypothesized model of cassava's importance among the sampled societies.

  8. Cultural adaptations after progressionismMcCall, Lauren W. - Cross-Cultural Research, 2009 - 2 Hypotheses

    This article challenges ideas of cultural progressionism through an analysis of counting systems. Cultural adaptation in both biotic and abiotic environments is examined, and results suggest that culture adapts to both the human-made environment and the physical environment. The author asserts that “interpreting divergent and convergent behaviors as due to differences and similarities of local environments” is superior to a progressionist approach to cultural change (62).

  10. Comparative Study of Territoriality across Forager SocietiesMoritz, Mark - Human Ecology, 2020 - 4 Hypotheses

    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.
