  1. Resource stress and subsistence diversification across societiesEmber, Carol R. - Nature Sustainability, 2020 - 4 Hypotheses

    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).

  2. Effects of Evolution, Ecology, and Economy on Human Diet: Insights from Hunter-Gatherers and Other Small-Scale SocietiesPontzer, Herman - Annual Review of Nutrition, 2021 - 2 Hypotheses

    This study, primarily a review on the evolution of the human diet, also includes a small study on the distribution of meat-eating and its relationship with climate and cultural factors, namely subsistence type. The authors find that societies with subsistence strategies that prioritize fishing, hunting, or pastoralism also tend to consume more animal products, whereas those that focus on agriculture have more plant-based diets. The authors argue that these small-scale societies have a healthier approach to diet than industrialized societies regardless of their subsistence type or meat consumption.

  3. Economic Systems of Foraging, Agricultural, and Industrial SocietiesFrederic L. Pryor - , 2005 - 26 Hypotheses

    The second and third parts of this book classify the economic systems of foraging and agricultural societies in the SCCS based on correlations between their institutions of property an distribution. These economic types are then examined for relationships with other social, political, demographic, and environmental factors in order to draw tentative conclusions regarding the origins of the Agricultural and Industrial Revolutions. The fourth part of the book uses cross-national data to examine similar associations in industrial/service economies, and is not included here.

  4. The global geography of human subsistenceGavin, Michael C. - Royal Society Open Science, 2018 - 8 Hypotheses

    In this article, the authors seek to determine cross-culturally valid predictors of dominant types of human subsistence around the world. They did this by formulating multiple models that incorporate different combinations of environmental, geographic, and social factors. These models were then used to test various hypotheses posed throughout the anthropological literature surrounding factors that determine dominant subsistence strategies.

  5. Hunter-gatherers have less famine than agriculturalistsBerbesque, J. Colette - Biology Letters, 2014 - 2 Hypotheses

    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.

  6. Starvation and famine: cross-cultural codes and some hypothesis testsDirks, Robert - Cross-Cultural Research, 1993 - 8 Hypotheses

    "This article provides a set of codes that rate the starvation and famine experiences of societies in the Standard Cross-Cultural Sample. The codes are used to test several theoretical generalizations regarding the underlying causes of famine." Results indicate that seasonal starvation and direct entitlements are the strongest predictors of famine.

  7. Population size predicts technological complexity in oceaniaKline, Michelle A. - Proceedings of the Royal Society of London B: Biological Sciences, 2010 - 3 Hypotheses

    The capacity for cumulative cultural evolution has often been invoked to explain the great diversity of habitats occupied by humans. This theory of cultural evolution emphasizes the gradual accumulation of technologies and cultural practices over many generations, and predicts that larger populations will generate more complex cultural adaptations than smaller, isolated ones. Here, the authors investigate the marine foraging tool repertoires of 10 Oceanic societies to determine whether population size and intergroup contact affect the cultural processes by which tool kits evolve.

  8. The Relationships of Extreme Precipitation and Temperature Events with Ethnographic Reports of Droughts and Floods in Nonindustrial SocietiesFelzer, B.S. - Weather, Climate, and Society, 2020 - 1 Hypotheses

    This paper asks if meteorological data can help predict instances of drought and flood in the ethnographic record, with the goal of being able to use such data to more easily evaluate the effect of climate/weather on cultural beliefs, practices, and attitudes. The authors develop several indices of droughts, floods, and extreme weather and test them by applying data from weather stations in close proximity to SCCS societies and comparing the predictions to ethnographic accounts of natural hazards. Weather data included daily precipitation, minimum temperature, and maximum temperature dating back as far as the 1950s. The authors found that precipitation - evaporation (P-E) measures and Palmer Drought Severity Index (PDSI) overpredicted droughts, whereas a combined drought measure underpredicted droughts, and that the flood indices generally were not very useful in predicting flood events. The authors suggest using P-E measures and PDSI to hindcast the presence of droughts, and the combined drought measure to hindcast the absence of droughts. They suggest that the overprediction of both floods and droughts is a result of extreme weather not necessarily having a severe impact on crop yields.

  9. 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.

  10. Mapping the middle ground between foragers and farmersDenham, Tim - Journal of Anthropological Archaeology, 2022 - 3 Hypotheses

    This study seeks to investigate the little-understood intermediate region between farming and foraging subsistence strategies. The authors seek to evaluate the extent to which such "middle-ground" subsistence methods actually exist, whether there is any geographical patterning to them, and if different crop assemblages/dependencies make middle-ground subsistence strategies more or less likely. They find that agro-pastoral, cereal-based societies in Africa and Eurasia are more likely to be dependent on farming (defined here as including both cultivation and animal husbandry), whereas societies in North America and those reliant on root crops and arboriculture in the wet tropics incorporate both farming and foraging. They conclude that there is likely more of a "middle-ground" between foraging and farming than has typically been allowed for in the literature.
