  1. Primary biomass will be negatively associated with local group area among foragers (62).Marlowe, Frank W. - Hunter-gatherers and human evolution, 2005 - 2 Variables

    This article explores the relationships between habitat and social organization among humans and other species. Diet, technology, group size, home range, mobility, kinship, marital residence, sexual division of labor, mating system, central places, food sharing, and egalitarianism are all considered.

  3. Technological complexity is positively associated with risk of resource failure (1).Collard, Mark - Risk, mobility or population size?: Drivers of technological richness among ..., 2013 - 6 Variables

    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.

  4. Number of residential moves per year will be negatively associated with percent contribution to diet through fishing and positively associated with percent contribution to diet through hunting and gathering (61).Marlowe, Frank W. - Hunter-gatherers and human evolution, 2005 - 4 Variables

    This article explores the relationships between habitat and social organization among humans and other species. Diet, technology, group size, home range, mobility, kinship, marital residence, sexual division of labor, mating system, central places, food sharing, and egalitarianism are all considered.

  5. Hunter-gatherer groups did not solely follow a Paleolithic Diet with given macronutrient ranges.Lieberman, Daniel E. - Comparing measured dietary variation within and between tropical hunter-gath..., 2023 - 3 Variables

    Do tropical hunter-gatherers follow the diet known today as the Paleo diet? Using nutritional data on 11 tropical hunter-gatherer groups, this study asses dietary composition. The results show that there are high levels of variation in the distribution of protein, fat, and carbohydrates among the sample of 11 hunter-gatherer groups.

  6. The percentage of gathering done by males will be positively associated with net primary productivity of plants (174).Marlowe, Frank W. - Hunting and gathering: the human sexual division of foraging labor, 2007 - 2 Variables

    This article explores the sexual division of labor among foragers, focusing on resource availability and constraints on women’s foraging activities. The authors conclude that “there is a greater division of foraging labor in more seasonal habitats where less gathering is possible and more extractive, tool-based foraging is required” (191).

  7. Evolution of shamanism will be positively associated with evolution of ancestor worship (273).Peoples, Hervey C. - Hunter-gatherers and the origins of religion, 2016 - 2 Variables

    What is the evolutionary sequence of beliefs in hunter-gatherers? The authors attempt to answer this question by reconstructing the development of various traits in traditional societies using phylogenetic and linguistic source trees. Testing for correlated evolution between this reconstruction and population history as proxied by linguistic classification suggests the presence of animism at profound time depth, aligning with classical anthropological religious theory put forth by E.B. Tylor. Coevolutions between other religious concepts including shamanism, ancestor worship, active ancestor worship, high gods, active high gods, and belief in an afterlife are also examined.

  8. Resource density is positively correlated with type of tenure system.Moritz, Mark - Comparative Study of Territoriality across Forager Societies, 2020 - 7 Variables

    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.
