  1. Pathogen intensity cross-culturallyLow, Bobbi S. - World Cultures, 1994 - 1 Hypotheses

    This article reviews prior findings associating sexual selection, polygyny, and pathogen stress. The author also presents descriptions of several pathogens to facilitate further research.

  2. Comparing explanations of polygynyEmber, Melvin - Cross-Cultural Research, 2007 - 4 Hypotheses

    This article uses logistic regression analysis to examine pathogen stress and male mortality in warfare as predictors of nonsororal polygyny. Differences between state and non-state societies are observed. The authors also retest variables from White and Burton's 1988 study on causes of polygyny, finding only fraternal interest groups and absence of plow significant.

  3. Cultural trait transmission and missing data as sources of bias in cross-cultural survey research: explanations of polygyny re-examinedDow, Malcolm M. - Cross-Cultural Research, 2009 - 1 Hypotheses

    This study retests the work by Ember, Ember and Low (2007) on male mortality and pathogen stress as predictors of nonsororal polygyny. The authors argue that the work of Ember, Ember, and Low is biased because it does not include a variable for cultural trait transmission. Restesting the original Ember, Ember and Low data, including a variable for cultural trait transmission, authors find that male mortality and pathogen stress loose their significance and cultural trait transmission is the only significant predictor of nonsororal polygyny.

  4. Marriage systems and pathogen stress in human societiesLow, Bobbi S. - American Zoologist, 1990 - 5 Hypotheses

    This article examines the relationship between pathogen stress and polygyny. Results indicate that there is a positive association between the two that is not confounded by geographic region, latitude, population density, male-male competition, or presence of brideprice. In particular, pathogen stress precicts higher levels of non-sororal polygyny and capturing women for wives or concubines.

  5. Symbolic or not-so-symbolic wounds: the behavioral ecology of human scarificationLudvico, Lisa Rose - Ethnology and Sociobiology, 1995 - 4 Hypotheses

    This article tests four hypotheses regarding scarification, which is described as 1) a rite of passage, 2) a hardening/trauma procedure, 3) a nonadaptive sexually selected character, or 4) an adaptive pathogen driven sexually selected character. Only the third hypothesis is supported in a worldwide sample, suggesting that scarification is associated with polygyny. The other three are each supported in different regional subsamples—principally the first hypothesis (supported in Africa, the Insular Pacific, and South America).

  6. Pathogen stress and polygyny in humansLow, Bobbi S. - Human Reproductive Behaviour: A Darwinian Perspective, 1987 - 2 Hypotheses

    This study tests the association between pathogen risk and degree of polygyny and sexual advertisement. Results show that the greater the risk of serious pathogens, the greater the degree of polygyny. The correlation between pathogen risk and sexual signals is only marginally significant. An association between mate choice and resource control is also examined.

  7. Material resource investments at marriage: evolutionary, social, and ecological perspectivesHuber, Brad R. - Ethnology, 2011 - 2 Hypotheses

    This article focuses on parents’ investment of material resources at the time of their child’s marriage. Two patterns emerge from the data: wealth is generally transferred from the groom’s family to the bride’s and from the couple’s parents to the bride and groom. Social and ecological factors are also examined. Multiple regression analysis shows that paternal confidence level, societal polygyny rate, and level of pathogen stress can affect the aforementioned wealth transfer patterns.

  8. Social resilience to climate-related disasters in ancient societies: a test of two hypothesesPeregrine, Peter N. - , 2017 - 2 Hypotheses

    In the present study, Peregrine tests two perspectives regarding social resilience to climate-related disasters: 1) that societies with more inclusive and participatory political structures (corporate political strategies) are more resilient to climate-related disasters, and 2) that societies with tighter adherence to social norms are more resilient to climate-related disasters. Results support the notion that societies with greater political participation are more socially resilient to catastrophic climate-related disasters. Because these results are justifiably generalizable across multiple historical and cultural contexts, Peregrine's findings are a useful contribution to aid in disaster response policy decision making.

  9. The kiss of death: three tests of the relationship between disease threat and ritualized physical contact within traditional culturesMurray, Damian R. - Evolution and Human Behavior, 2016 - 3 Hypotheses

    In order to evaluate an adaptive justification for restriction of ritualized physical contact, the authors test association between three manifestations of physical interaction and prevalence of pathogens cross-culturally. Their expectation, supported by two of the three tested hypotheses, is that higher pathogen prevalence will lead to customs of restricted physical contact. Both cultural and biological evolution are suggested to be influential in selecting for physically intimate behaviors.

  10. Pathogens and politics: further evidence that parasite prevalence predicts authoritarianismMurray, Damian R. - PLoS ONE, 2013 - 3 Hypotheses

    This article employs cross-national and cross-cultural methods to investigate whether pathogen stress is a direct determinant of authoritarianism. The study controls on other factors such as famine, warfare, and malnutrition and evaluates alternative causal models.
