  1. Societies with EIM or Ecologically Imposed Monogamy (monogamy combined with egalitarian resource structure) will have lower sexual stature dimorphism than those practicing polygyny or Socially-Imposed Monogamy (SIM, monogamy in highly stratified societies). (471)Gaulin, Steven JC - Human marriage systems and sexual dimorphism in stature, 1992 - 3 Variables

    The researchers operationalize new measures of Socially Imposed Monogamy (SIM) and Ecologically Imposed Monogamy (EIM) using scores from Murdock's (1986) Ethnographic Atlas in order to reevaluate Alexander et al.'s (1979) findings that sexual stature dimorphism is higher in SIM (monogamous and highly stratified) and polygynous societies compared to EIM (monogamous and egalitarian) ones. The expected associations between marriage system and sexual dimorphism are not robustly significant; however, an interaction effect is discovered between marriage system and stratification with regard to dimorphism.

  2. The degree of sexual dimorphism of stature will be associated with the degree of polygyny in human societies (434).Alexander, Richard D. - Sexual dimorphisms and breeding systems in pinnipeds, ungulates, primates, a..., 1979 - 2 Variables

    This study examines the relationship between sexual dimorphism and degree of polygyny. Authors test this relationship in both humans and non-human species. In non-human species, every correlation between sexual dimorphism (measured by body length) and degree of polygyny was significant. In human populations, sexual dimporhism was not related to degree of polygyny, however, there were some differences between populations with socially imposed monogomy and those with ecologically imposed monogamy.

  3. Human sexual dimorphism of stature will be associated with latitude category (409, 413).Wolfe, Linda D. - Latitude and intersocietal variation of human sexual dimorphism of stature, 1982 - 2 Variables

    This article examines the relationship between sexual dimorphism of stature and latitude; data support the association. The authors also find support for an association between latitude and human marriage systems, a variable proposed by Alexander (1979) to explain variation in sexual dimorphism of stature. When societies are categorized by latitude, the relationships between marriage systems and sexual dimorphism do not reach significance. Overall the authors emphasize the influence of environmental adaptation on sexual dimorphism rather than an explanation solely focused on male-male competition.

  4. Polygyny will be associated with greater sexual dimorphism of stature (443).Gray, J. Patrick - Height and sexual dimorphism of stature among human societies, 1980 - 2 Variables

    This article explores the relationship between sexual dimorphism of stature and variables of marriage, diet, subsistence and environment. Significant associations were found between security and plentifulness of food supply, protein availability, and sexual dimorphism of stature.

  5. Polygyny will be positively associated with sexual dimorphism of stature (225).Wolfe, Linda D. - A cross-cultural investigation into the sexual dimorphism of stature, 1982 - 2 Variables

    This article examines height and sexual dimorphism of stature from a sociobiological perspective. Diet, child rearing, and marriage practices are tested as possible factors contributing to height sexual dimorphism of stature. Results provide some support for a nutritional hypotheses, but sexual selection and parental investment are not statistically significant.

  6. There will be a higher degree of sexual dimprphism in societies where there is a higher degree of division of labor by sex (576).Wolfe, Linda D. - Subsistence practices and human sexual dimorphism of stature, 1982 - 2 Variables

    This study tests the validity of two previous diachronic studies examining the relationship between subsistence strategy and sexual dimorphism of stature with synchronic data. The authors find that neither hypothesis is valid.

  7. Agricultural societies should exhibit a lower degree of sexual dimorphism than non-agricultural societies (576).Wolfe, Linda D. - Subsistence practices and human sexual dimorphism of stature, 1982 - 2 Variables

    This study tests the validity of two previous diachronic studies examining the relationship between subsistence strategy and sexual dimorphism of stature with synchronic data. The authors find that neither hypothesis is valid.

  8. The degree of monogamy is negatively associated with the degree of sexual dimorphism of stature among human societies (129).Gray, J. Patrick - Correlates of monogamy in human groups: tests of some sociobiological hypotheses, 1984 - 2 Variables

    This study re-examines the hypotheses offered by Kleiman (1977) linking monogamy in humans to monogamy in other animals. Of seven hypotheses, only two were weakly supported when using a cross-cultural analysis.

  9. High level of nutrition will be positively associated with sexual dimorphism of stature (228).Wolfe, Linda D. - A cross-cultural investigation into the sexual dimorphism of stature, 1982 - 2 Variables

    This article examines height and sexual dimorphism of stature from a sociobiological perspective. Diet, child rearing, and marriage practices are tested as possible factors contributing to height sexual dimorphism of stature. Results provide some support for a nutritional hypotheses, but sexual selection and parental investment are not statistically significant.

  10. Men in agricultural societies will be more likely to invest in their offspring (via inheritance) than men in hunter-gatherer societies (239).Gaulin, Steven J.C. - Sexual dimorphism in the human post-reproductive life-span: possible causes, 1980 - 2 Variables

    This study tests possible explanations for sexual dimorphism in human post-reproductive life-spans. The author focuses on explanations involving male paternal investment and finds that men in agricultural societies are more likely to invest in their offspring than men in hunter-gatherer societies.
