  1. A variety of ecological, economic, and anthropological factors will predict the prevalence of land ownership.Kavanagh, Patrick H. - Drivers of global variation in land ownership, 2021 - 11 Variables

    The article discusses the role of land ownership in natural resource management and social-ecological resilience, and explores the factors that determine ownership norms in human societies. The study tests long-standing theories from ecology, economics, and anthropology regarding the potential drivers of land ownership, including resource defensibility, subsistence strategies, population pressure, political complexity, and cultural transmission mechanisms. Using cultural and environmental data from 102 societies, the study found an increased probability of land ownership in mountainous environments and societies with higher population densities. The study also found support for the idea that neighboring societies might influence land ownership. However, there was less support for variables associated with subsistence strategies and political complexity.

  2. Population size will be positively associated with the development of social inequality.Haynie, Hannah J. - Pathways to social inequality, 2021 - 2 Variables

    In this study, the authors examine pathways to social inequality, specifically social class hierarchy, in 408 non-industrial societies. In a path model, they find social class hierarchy to be directly associated with increased population size, intensive agriculture and large animal husbandry, real property inheritance (unigeniture) and hereditary political succession, with an overall R-squared of 0.45. They conclude that a complex web of effects consisting of environmental variables, mediated by resource intensification, wealth transmission variables, and population size all shape social inequality.

  3. Resource intensification will be associated with the development of social inequality.Haynie, Hannah J. - Pathways to social inequality, 2021 - 3 Variables

    In this study, the authors examine pathways to social inequality, specifically social class hierarchy, in 408 non-industrial societies. In a path model, they find social class hierarchy to be directly associated with increased population size, intensive agriculture and large animal husbandry, real property inheritance (unigeniture) and hereditary political succession, with an overall R-squared of 0.45. They conclude that a complex web of effects consisting of environmental variables, mediated by resource intensification, wealth transmission variables, and population size all shape social inequality.

  4. Norms favoring the hereditary transmission of wealth will influence the development of institutionalized social inequality.Haynie, Hannah J. - Pathways to social inequality, 2021 - 4 Variables

    In this study, the authors examine pathways to social inequality, specifically social class hierarchy, in 408 non-industrial societies. In a path model, they find social class hierarchy to be directly associated with increased population size, intensive agriculture and large animal husbandry, real property inheritance (unigeniture) and hereditary political succession, with an overall R-squared of 0.45. They conclude that a complex web of effects consisting of environmental variables, mediated by resource intensification, wealth transmission variables, and population size all shape social inequality.

  5. The net primary productivity of agriculturalists’ will be greater than that of foragers’ land.Porter, Claire C. - How marginal are forager habitats?, 2007 - 2 Variables

    This article examines the quality of forager habitats to determine whether agriculturalists occupy the most productive areas while modern forager groups are relegated to poor habitats. Findings indicate that there are slight but insignificant differences in the net primary productivity of foragers’ land and agriculturalists’ land. Further analysis of types of agriculturalists suggest that horticulturalists live in the most productive habitats, followed by intensive agriculturalists and finally pastoralists.

  7. Agriculture arose out of necessity as environmental conditions deterioratedKavanagh, Patrick H. - Hindcasting global population densities reveals forces enabling the origin o..., 2018 - 2 Variables

    The researchers, using principal component analysis, generalized additive models across 12 agriculture origin locations, and a model predicting hunter-gatherer population density, evaluate hindcasted population density trends to suggest predictors of the development of agriculture. Using domestication as an indicator of agriculture, they test 3 competing hypotheses regarding agriculture development. Their results are consistent with the "surplus" hypothesis, indicating that agriculture arose as population densities increased along with environmental capabilities.

  8. Relative reliance on consonants vs. vowels in human languages cross-culturally will be associated with different environments (5).Maddieson, Ian - Human language diversity and the acoustic adaptation hypothesis, 2015 - 10 Variables

    In the field of bioacoustics, the Acoustic Adaptation theory suggests that variation in vocalization across different species can be accounted for by the acoustic properties of different habitats. Here, the researchers test consonant- and vowel-heaviness in human languages against various environmental variables in order to examine the theory's potential application to our own species. The authors identify a significant negative correlation between consonant heaviness and temperature, precipitation, and tree cover, and some positive correlation with rugosity and elevation as their most important findings, while acknowledging the potentially influential roles of migration and demographic factors in producing this relationship.

  9. Resource scarcity will be positively associated with the taking of land and movable property during warfare and negatively associated with the taking of people during warfare (37).Ember, Carol R. - Risk, uncertainty, and violence in eastern Africa: a regional comparison, 2012 - 3 Variables

    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.

  10. Rate of exogamy will be positively associated with disparities in productivity between the two residence sites. (1807)Dow, Gregory K. - The economics of exogamous marriage in small‐scale societies, 2016 - 12 Variables

    The authors develop and empirically test a model in which exogamy is negatively predicted by community size, due to decreasing heterogeneity from endogenous marriages in small settlements, and positively predicted by disparity in productivity between communities which is 'smoothed out' by transfer of community members through exogamous marriages. Support for both predictions is found, which is used to argue that cultural traits like marriage customs are heavily influenced by population-environment relationships.
