  1. "[Societies] with a high male loss in warfare are significantly more likely to have an imbalanced sex ratio in favor of females than . . . [societies] with a low or zero male loss in warfare" (201-202)Ember, Melvin - Warfare, sex ratio and polygyny, 1974 - 2 Variables

    This paper suggests that polygyny may be best explained by uneven sex ratios, particularly an excess of women while men are engaged in warfare. The author also considers Whiting’s 1964 theory that used post-partum sex taboos to explain polygyny. These two theories are tested cross-culturally and results suggest that polygyny is a response to an unbalanced sex ratio in favor of women.

  2. "In the presence of a short [postpartum sex] taboo, which is the more crucial control situation, . . . [there is a strong] correlation between high male mortality and polygyny" (202)Ember, Melvin - Warfare, sex ratio and polygyny, 1974 - 3 Variables

    This paper suggests that polygyny may be best explained by uneven sex ratios, particularly an excess of women while men are engaged in warfare. The author also considers Whiting’s 1964 theory that used post-partum sex taboos to explain polygyny.

  3. "There is no significant association between a long postpartum taboo and polygyny in either the high or low male mortality situation . . . when we control for male mortality in warfare" (202)Ember, Melvin - Warfare, sex ratio and polygyny, 1974 - 3 Variables

    This paper suggests that polygyny may be best explained by uneven sex ratios, particularly an excess of women while men are engaged in warfare. The author also considers Whiting’s 1964 theory that used post-partum sex taboos to explain polygyny. These two theories are tested cross-culturally and results suggest that polygyny is a response to an unbalanced sex ratio in favor of women.

  4. "However, when we control on Whiting's predictor, i.e., presence or absence of a long postpartum sex taboo, a strong relationship between high male mortality and polygyny still obtains, in the presence of both a long and a short postpartum sex taboo" (202)Ember, Melvin - Warfare, sex ratio and polygyny, 1974 - 3 Variables

    This paper suggests that polygyny may be best explained by uneven sex ratios, particularly an excess of women while men are engaged in warfare. The author also considers Whiting’s 1964 theory that used post-partum sex taboos to explain polygyny. These two theories are tested cross-culturally and results suggest that polygyny is a response to an unbalanced sex ratio in favor of women.

  5. "A high male mortality in warfare is strongly associated with polygyny" (202)Ember, Melvin - Warfare, sex ratio and polygyny, 1974 - 2 Variables

    This paper suggests that polygyny may be best explained by uneven sex ratios, particularly an excess of women while men are engaged in warfare. The author also considers Whiting’s 1964 theory that used post-partum sex taboos to explain polygyny.

  6. Sex ratio will predict the percent of married men who are polygynous.Minocher, Riana - Explaining marriage patterns in a globally representative sample through soc..., 2019 - 2 Variables

    Researchers examine marriage patterns of 186 societies from the Standard Cross-Cultural Sample (SCCS). The eleven predictor variables are pathogen stress, arranged female marriages, population density, father roles during infancy, temperature, social stratification, wealth inequality, internal warfare, assault frequency, female agricultural contribution, and sex ratio. The two outcome variables measuring polygyny are cultural rules constraining polygyny and the percentage of married men who are polygynous. Controlling on phylogeny using a global supertree of the languages, analysis of marriage patterns reveals that assault frequency and pathogen stress are the strongest predictors of polygyny. These findings offer additional support for the theories of harem-defense polygyny and male genetic quality.

  7. In a multiple regression, father-infant sleeping distance will be associated with warfare frequency, marrying enemies, and polygyny (108).Ember, Carol R. - War and socialization of children: comparing two evolutionary models, 2007 - 4 Variables

    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.

  9. A short supply of women will be positively associated with the frequency of warfare--Divale and Harris (251)Ember, Carol R. - Resource Unpredictability, mistrust, and war: a cross-cultural study, 1992 - 2 Variables

    The article tests theories that may explain why warfare frequency varies from society to society. The focus is on ecological problems, particularly different kinds of resource scarcity, but social and psychological theories are also tested with both bivariate and multivariate analyses. Because unpredictable disasters are such a strong predictor in nonstate societies, the authors theorize that war may mostly be caused by a fear of nature.

  10. Controlling on age at marriage, the presence/absence of male mortality in warfare will be associated with polygyny (13).Ember, Melvin - Alternative predictors of polygyny, 1984 - 3 Variables

    "This paper describes how the "sex-ratio" explanation of polygyny compares with some alternative, supposedly causal explanations. The results suggest that polygyny is best predicted by two statistically independent factors--high male mortality in warfare…and delayed age of marriage for men."
