  1. Sexual dimorphism in stature will be associated with variation in the sexual division of labor (27).Holden, Clare - Sexual dimorphism in stature and women's work: a phylogenetic cross-cultural..., 1999 - 2 Variables

    This article presents a phylogenetic approach to studying sexual dimorphism of stature. Results show a significant association between sexual division of labor and sexual dimorphism of stature.

  3. Pastoralism is always adopted prior to the development of high lactose digestion capacity among adults (615).Holden, Clare - Phylogenetic analysis of the evolution of lactose digestion in adults, 1997 - 2 Variables

    The ability of adults to digest lactose is common only in populations of European and circum-Mediterranean origin, a distribution thought to be a result of genetic adaptation to drinking milk from domestic livestock. Two additional hypotheses have been proposed to explain the distribution of high lactose digestion capacity: (1) supplemental calcium in high-latitude populations prone to vitamin D deficiency and (2) maintenance of water and electrolytes in the body in highly arid environments. However, these hypotheses are confounded by the shared ancestry of populations whose lactose digestion capability has been tested. Therefore, the authors test all three hypotheses using a phylogenetic comparative method for 62 cultures.

  4. Hunters and gatherers will experience less frequent and drastic famine than other subsistence types (38).Dirks, Robert - Starvation and famine: cross-cultural codes and some hypothesis tests, 1993 - 3 Variables

    "This article provides a set of codes that rate the starvation and famine experiences of societies in the Standard Cross-Cultural Sample. The codes are used to test several theoretical generalizations regarding the underlying causes of famine." Results indicate that seasonal starvation and direct entitlements are the strongest predictors of famine.

  5. Security and plentifulness of food supply will be associated with sexual dimorphism of stature (452).Gray, J. Patrick - Height and sexual dimorphism of stature among human societies, 1980 - 3 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.

  7. Protein availability will be associated with sexual dimorphism of stature (453).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.

  8. High lactose digestive capacity among adults evolved in populations that kept livestock (615).Holden, Clare - Phylogenetic analysis of the evolution of lactose digestion in adults, 1997 - 2 Variables

  9. Contribution of women to subsistence is associated with women's ability to control resources produced by men (5)Low, Bobbi S. - Sex, power, and resources: ecological and social correlates of sex differences, 1990 - 2 Variables

    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.

  10. 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.
