  1. The frequency of G6PD deficiency is positively correlated with pathogen load index (402).Borinskaya, S. A. - Combination of Genetic and Humanitarian (Cross-Cultural) Methods for the Ide..., 2015 - 2 Variables

    Researchers used population samples from the ALFRED database and the Human Genome Diversity Project (HGDP), in conjunction with 68 populations from the Ethnographic Atlas, in an attempt to identify specific genes involved in human adaptation to environmental stimuli as a result of migration. Specifically, researchers looked at the allele frequencies for four different genes typically associated with varying subsistence forms. These four included the APOE apolipoprotein E gene (lipid transport and regulation of cholesterol), LCT lactase gene (enzyme that decomposes lactose), CCR5 chemokine receptor gene (deletion mutation that decreases immunodeficiency virus propagation), and the ADH1B alcohol dehydrogenase gene (important enzyme for alcohol metabolism). The allele frequencies were then analyzed to distinguish any possible correlation to economic-culture types using a two-sided Spearman Test. Researchers also ran a similar test to analyze allele frequencies and pathogen load, however the majority of the findings were not statistically significant. The findings suggest that there is a definite relationship between the allele frequencies and type of economy of a population.

  7. Societies with unreliable food supplies and undeveloped food storage technology will tend to have plump standards of female beauty (215).Anderson, Judith L. - Was the Duchess of Windsor right?: A cross-cultural review of the socioecolo..., 1992 - 2 Variables

    Cultures vary widely in regards to beauty standards for female body fat: while industrialized nations typically prefer thinness in women, ethnographic reports indicate that plumpness is valued in many small-scale societies. Here the authors evaluate several hypotheses that relate variation in female body fat preference to variation in socioecology such as food storage, climate, male social dominance, valuation and restriction of women's work, and female stress during adolescence.

  8. Material complexity will be positively associated with later-stage number terms (23).Overmann, Karenleigh A. - Material scaffolds in numbers and time, 2013 - 2 Variables

    This paper examines the relationship between the complexity of a society's material culture and its development of cognitive technologies for numeration and timekeeping. The researcher claims that the resulting positive correlation between these variables as support for a theory of material culture as 'scaffolding' for number concepts, providing tangible, shareable, manipulable forms for abstract numerical constructions.

  9. The presence of horses, food storage, and formal resource ownership will each be negatively associated with a lack of class stratificationHooper, Paul L. - Gains to cooperation drive the evolution of egalitarianism, 2021 - 4 Variables

    This article is mainly concerned with understanding the motivators toward egalitarianism through modeling via a game that combined elements from both hawk-dove and prisoners dilemma. While most of the article is focused on this model, the researchers also tested their hypotheses cross-culturally on a sample of forager societies. In both cases, they found evidence that the benefits of cooperation drove egalitarianism.

  10. In hunter-gatherer societies, divorce is common (407)Apostolou, Menelaos - Sexual selection under parental choice: the role of parents in the evolution..., 2007 - 2 Variables

    This study reveals that in hunting and gathering societies thought to be akin to those of our ancestors, female choice is constained by the control that parents exercise over their daughters. Since parental control is the typical pattern of mate choice among extant foragers, it is likely that this pattern was also prevalent throughout human evolution.
