  1. There will be a stronger negative relationship between spousal relatedness and offspring fitness among foragers than among non-foragers. (2)Bailey, Drew H. - Fitness consequences of spousal relatedness in 46 small-scale societies, 2014 - 4 Variables

    The authors predict that fitness outcomes will be negatively associated with spousal relatedness among foragers but positively associated among non-foragers, due to the greater social benefits of intensive kinship systems among non-foragers. Support is found for this hypothesis; however, an interaction effect is discovered with inbreeding, which appears to account for the variability in these relationships independent of subsistence activity. The authors qualify this support in order to explain why the incidence of cousin-marriage in non-foraging societies is not higher.

  2. Climate and subsistence type will be associated with the percentage of animal foods in the diet.Pontzer, Herman - Effects of Evolution, Ecology, and Economy on Human Diet: Insights from Hunt..., 2021 - 3 Variables

    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. Longer exposure to the Western Church should be associated with less intensive kin-based institutions (2-3)Schulz, Jonathan F. - The Church, intensive kinship, and global psychological variation, 2019 - 2 Variables

    This article draws from anthropology, psychology, and history to gain insight into the causes of large-scale psychological variation among humans. The authors of this study are mainly concerned with the way that weak kinship structures induced by policies of the Western Church in Europe may have resulted in the modern "WEIRD" (an acronym for "Western, Educated, Industrialized, Rich, and Democratic") psychological profiles in that same region. By correlating the amount of contact with the Western Church, rates of cross-cousin marriage (as an element of kin tightness), and degrees of individualism (as an element of WEIRD psychology), the authors are able to find support for this theory.

  4. Gathering is the most important subsistence activity among hunter-gatherers (440).Ember, Carol R. - Myths about hunter-gatherers, 1978 - 1 Variables

    This article challenges common assumptions about hunter-gatherers and demonstrates that previous ideas about residence, division of labor and warfare are not supported by the cross-cultural data.

  5. Populations with less intensive kin-based institutions will be less conforming but more individualistic and impersonally prosocial (2)Schulz, Jonathan F. - The Church, intensive kinship, and global psychological variation, 2019 - 2 Variables

  6. Female contribution to subsistence will be positively associated with polygyny (p. 702).Lee, Gary R. - Marital structure and economic systems, 1979 - 2 Variables

    This article tests a broad hypothesis that marital structure is associated with economic type. Results indicate that where women's potential contribution to subsistence is high (as in gathering and agricultural societies), women's contribution is positively associated with polygyny. By contrast, in fishing, hunting, and herding societies, female contribution to subsistence is generally minimal and has a negative association with polygyny.

  7. In societies where males marry before the age of twenty, polygyny will be prevalent (243, 260).Textor, Robert B. - A Cross-Cultural Summary: Polygyny, 1967 - 2 Variables

    Textor summarizes cross-cultural findings on polygyny pertaining to cultural, environmental, psychological, and social phenomena.

  9. In a multiple regression, father-infant sleeping distance will be associated with warfare frequency, marrying enemies, and polygyny (108).Ember, Carol R. - War and socialization of children: comparing two evolutionary models, 2007 - 4 Variables

    This article presents two evolutionary models that may explain relationships between war and socialization of children: the "environmentally contingent reproductive strategy" (ECRS) model put forward by Draper and Harpending (1982), and a model put forward by Carol and Melvin Ember. Results do not provide support for the hypotheses involving father-infant sleeping proximity derived from the ECRS model. The authors also find some inconsistencies with their own model.

  10. Inbreeding will be negatively associated with pathogen risk (125).Thornhill, Nancy Wilmsen - The evolutionary significance of incest rules, 1990 - 2 Variables

    This article investigates incest rules, proposing that they are instituted by rulers as a way of preventing wealth-concentration among non-ruling families. Three hypotheses are derived and supported with empirical analysis. Two alternative evolutionary hypotheses are discussed and dismissed by the author.
