  1. Sexually transmitted disease and gender roles: an index of cultural evolutionMackey, Wade C. - Cross-Cultural Research, 2007 - 1 Hypotheses

    This article examines the relationship between HIV/AIDS and several parameters of a nation’s demography, including income, mortality, labor, fertility, and homicide rates. Associations were supported by statistical tests. Regional differences are considered; Europe and the Muslim area had lower level of women’s HIV/AIDS infection. Four cultural adaptations to combat STDs are discussed.

  2. Extracted-Food Resource-Defense Polygyny in Native Western North American Societies at ContactSellen, Daniel W. - Current Anthropology, 2004 - 3 Hypotheses

    In this article, the authors seek to understand the connection between male resource-holding potential and male mating success. This connection has been suggested by behavioral ecologists as a way of explaining differing rates of polygyny across cultures. The authors investigate this relationship by testing the relationship between rates of polygyny and male control of local subsistence sites among North American societies during the period of contact. They find a positive relationship between these two variables for both terrestrial and aquatic game, but not for gathered plants. This suggests support for the theory.

  3. Men’s status and reproductive success in 33 nonindustrial societies: Effects of subsistence, marriage system, and reproductive strategyvon Rueden, Christopher R. - Proceedings of the National Academy of Sciences, 2016 - 2 Hypotheses

    The researchers examine associations between male status and various measures of reproductive success among foraging/non-foraging, and monogamous/polygynous societies in order to test the "egalitarian hypothesis" which predicts lower status effects in hunter-gatherer groups. Contrary to this hypothesis, they find that male social status is equally significantly associated with reproductive success in foraging and nonforaging societies. Additional support is found for the "mating effort" hypothesis, which predicts that male reproductive success will be more associated with fertility than offspring mortality in polygynous societies, leading the authors to make various suggestions regarding the evolutionary mechanisms at play.

  4. Male contribution to diet and female reproductive successMarlowe, Frank W. - Current Anthropology, 2001 - 3 Hypotheses

    This article seeks to understand male-female bonding by testing the relationship between male contribution to subsistence (a proxy for male provisioning) and female reproductive success in foraging societies. Analysis supports a positive association.

  5. Fertility and the ploughAlesina, Alberto - The American Economic Review, 2011 - 2 Hypotheses

    The researchers examine Boserup's (1970) theory that variation in traditional agricultural practices shape gender roles by examining the relationship between historical plough use and contemporary fertility rates and preferential attitudes towards fertility. Contrary to expectation, tests show a negative relationship between plough use and both of these variables. The authors theorize that since children are less capable of performing the intensive labor required by plough agriculture compared to hoe agriculture, adoption of the plough deincentivized increased fertility and reduced its value among agriculturalists.

  7. Relationships between subsistence and age at weaning in "preindustrial" societiesSellen, Daniel W. - Human Nature, 2001 - 3 Hypotheses

    This study tests the weaning food availability hypothesis, that both the introduction of foods other than breastmilk and the cessation of breastfeeding will vary by society's subsistence type. This hypothesis has implications for demography, as accelerated weaning can lead to increases in both mothers' fertility (due to decreased birth intervals) and infant mortality (due to the presence of pathogens in new foods).

  8. Adolescent fertility and risky environments: a population-level perspective across the lifespanPlacek, Caitlyn D. - Proceedings of the Royal Society B, 2012 - 3 Hypotheses

    This study provides the first tests of the relationships between population-level adolescent fertility rates and mortality risk at two different time points. The hypotheses are based in life-history theory, which predicts that human reproductive choices are shaped by mortality. The authors find that reproductive strategies are significantly predicted by both early (between ages 1-7) risks of mortality and current cues of mortality risk.

  9. Coevolution of landesque capital intensive agriculture and sociopolitical hierarchySheehan, Oliver - Proceedings of the National Academy of Sciences of the United States of America, 2018 - 3 Hypotheses

    Using phylogenetic methods, this research examines the relationship between landesque capital intensive agriculture ("permanent changes to landscape, such as construction of terraces and irrigation canals"(3631)) , political complexity, and social stratification amongst 155 Austronesian-speaking societies. Researchers attempted to find an underlying causality between the above mentioned variables, which have already been shown to be cross-culturally related. Results of statistical testing are most consistent with their being no clear causal link between the tested variables. The researchers claim this demonstrates social complexity and the multifaceted nature of cultural evolution.

  10. Dowry as female competitionGaulin, Steven J.C. - American Anthropologist, 1990 - 2 Hypotheses

    This study tests two models that predict the presence of dowry cross-culturally: the female competition model and the labor-value model. Results suggest that both models are predictive of dowry, however discriminant analysis finds the female competition model to be superior.
