  1. 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.

  2. Sex, power, and resources: ecological and social correlates of sex differencesLow, Bobbi S. - International Journal of Contemporary Sociology, 1990 - 15 Hypotheses

    This article focuses on ecological correlates of sexual division in the control of resources. The author tests several ecological theories put forth by others. Sex coalitions are examined in humans, and sexual dimorphism in resource acquisition and control is discussed.

  3. Human responses to environmental extremeness and uncertainty: a cross-cultural perspectiveLow, Bobbi S. - Risk and Uncertainty in Tribal and Peasant Economies, 1988 - 5 Hypotheses

    This article focuses on the effect of environmental extremes and unpredictability on human behavior and reproductive strategies. Significant correlations were found between environmental extremes and unpredictability and several variables, including mobility, subsistence mode, and degree of 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. War and socialization of children: comparing two evolutionary modelsEmber, Carol R. - Cross-Cultural Research, 2007 - 6 Hypotheses

    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.

  6. Pathogen stress and living organization: A cross-cultural analysisTinston, Jennifer - The Human Voyage: Undergraduate Research in Biological Anthropology, 2018 - 3 Hypotheses

    The present study examines the relationship between pathogen prevalence and the domestic living-organization of 186 societies from the Standard Cross-Cultural Sample (SCCS). The measurement for pathogen stress consists of ten diseases described by Low (1991) and Caden and Steele (2013). These are dengue, typhus, plague, filariae, schistosomes, leishmanias, trypanosomes, malaria, leprosy, and spirochetes; the transmission for these diseases was contagious and/or mobile. The measurement for the living organization came from the 'Household Form' variable by Murdock and White (1969). The seven categories of household form variable were then re-coded into two variables. The first is modular, which includes single-family and family homestead. The second is communal and includes large communal structure, multifamily household, husband rotates, individuals, married, and husband separate. The findings offer support for the evolutionary hypothesis that modular living is adaptive because it may reduce pathogen stress. Specifically, pathogen stress is influential in the way people live.

  7. The mating system of foragers in the standard cross-cultural sampleMarlowe, Frank W. - Cross-Cultural Research, 2003 - 1 Hypotheses

    This article examines variation in polygyny among foragers. Empirical analysis suggests that the level of male provisioning influences mating systems: higher male contribution to subsistence is associated with monogamy. The influences of pathogen stress, male-male competition, and male coercion are also considered.

  8. 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.

  9. Explaining monogamy and polygyny among foragers and horticulturalistsHooper, Paul L. - , 2006 - 5 Hypotheses

    This article tests several hypotheses related to the presence or absence of polygyny. Results suggest a negative relationship between polygyny and male provisioning, and positive relationships between polygyny and warfare, interpersonal aggression, and pathogen stress.

  10. Sexual selection and human ornamentationLow, Bobbi S. - Evolutionary Theory and Human Social Organization, 1979 - 6 Hypotheses

    This chapter examines the role of male and female ornamentation. Several hypotheses concerning mating systems and ornamentation are empirically tested; several are supported.
