  1. Global mandibular morphological variation will be associated with geographic distance (19546).von Cramon-Taubadel, Noreen - Global human mandibular variation reflects differences in agricultural and h..., 2011 - 2 Variables

    The researchers test the relationship between global mandibular morphology variation and susbsistence economy, population history, geography, and climate. While some mandibular variation is significantly correlated with geography, the most significant relationship is with subsistence activity. The strength of the relationship leads the authors to speculate on how masticatory behavior might have affected jaw shape, either through stress, weaning behavior, or other demographic factors.

  2. Home range is smaller with increasing actual transpiration.Hamilton, Marcus J. - Nonlinear scaling of space use in human hunter-gatherers, 2007 - 2 Variables

    Using a representative sample of 339 hunter-gatherer societies, researchers examine the relationship between hunter-gatherer use of space, size of population and supply of resources to see if they are similar to other organisms. By combining all factors into a single model, the authors claim to explain 86% of the variation in home range. Hunters have greater resource distribution than gatherers but both more so than aquatic foragers. Lastly, terrestrial foragers have more extensive home ranges than aquatic foragers.

  5. Homosexuality will be more prevalent in agropastoral than in hunting & gathering societies (1).Apostolou, Menelaos - Is homosexuality more prevalent in agropastoral than in hunting and gatherin..., 2016 - 2 Variables

    The researcher predicts a positive association between prevalence of homosexuality and agricultural and pastoral subsistence types, reasoning that higher frequency of arranged marriages among agropastoral societies will lessen negative selection pressure on genes which encode for non-exclusive heterosexual orientation. Findings appear to support the prediction.

  6. Homosexuality will be more prevalent in agropastoral than in hunting & gathering societies when controlling for community size. (6)Apostolou, Menelaos - Is homosexuality more prevalent in agropastoral than in hunting and gatherin..., 2016 - 3 Variables

    The researcher predicts a positive association between prevalence of homosexuality and agricultural and pastoral subsistence types, reasoning that higher frequency of arranged marriages among agropastoral societies will lessen negative selection pressure on genes which encode for non-exclusive heterosexual orientation. Findings appear to support the prediction.

  7. Using multivariate clustering, it is expected that patterns in human subsistence variability will be found that are consistent with the thery of "attractors" and "repellers." (9580)Ullah, Isaac I. T. - Toward a theory of punctuated subsistence change, 2015 - 6 Variables

    The authors use a comparative ethnoarchaeological model that seeks to test the applicability of Dynamical Systems Theory to modeling subsistence variation (namely the foraging-farming transition). The authors utilize the concepts of "attractors," which tend to stabilize a system, and "repellors," which tend to be destabilizing forces. Authors hope that this multidimensional approach, which assumes that several "controlling" variables disproportionately affect change within subsistence systems, will adequately model the nonlinearity and heterogeneity seen in the emergences of (and variations within) human subsistence systems throughout human history. Their model and premises regarding disproportionally-controlling variables appear to be supported.

  9. Productivity (a measure of subsistence type), is positively associated with the presence of High Gods (p. 2t5).Peoples, Hervey C. - Subsistence and the evolution of religion, 2012 - 2 Variables

    This study exmaines the presence of High Gods in societies as a function of subsistence type, population size, and stratification. High Gods are thought to be a mechanism to encourage collective action in the face of environmental challenges. Animal husbandry was found to be a strong predictor of High Gods, especially gods that are active in human affairs or morally supportive.
