  1. Slavery as a system of production in tribal societyBaks, C. - Bijdragen tot de Taal-, Land- en Volkenkunde, 1966 - 2 Hypotheses

    This article examines the conditions under which slavery occurs in preindustrial societies. Results suggest that social stratification and the existence of open resources are both necessary conditions for the occurrence of slavery.

  2. An anthropological perspective on obesityBrown, Peter J. - Annals of the New York Academy of Sciences, 1987 - 2 Hypotheses

    The authors implement an anthropological approach to explore the evolutionary and cultural explanations of modern obesity. Three widely accepted facts are considered: (1) gender dimorphism (women having higher levels of fat), (2) increase of obesity with modernization, and (3) a positive association between obesity and socioeconomic status. Using theory, cross-cultural research, and case studies, the authors hypothesize how obesity may have been selected for (or not selected against) in an evolutionary context considering both biological and social factors.

  3. Solidarity, stratification and sentiment: the unilateral cross-cousin marriage according to the theories of levi-strauss, leach, and homans and schneiderBerting, J. - Bijdragen tot de Taal-, Land- en Volkenkunde, 1960 - 4 Hypotheses

    This article tests differing theories of why a man's marriage of his mother's brother's daughter is often encouraged while marriage of the father's sister's daughter is discouraged. Maintenance of relationships between bride-givers and bride takers is considered, as are the role of childhood sentiments in choosing a spouse.

  5. Global phylogenetic analysis reveals multiple origins and correlates of genital mutilation/cuttingŠaffa, Gabriel - Nature Human Behavior, 2022 - 12 Hypotheses

    This study is a comprehensive analysis of female and male genital mutilation/cutting (FGM/C and MGM/C) practices, including their history and socio-ecological correlates, using a phylogenetic cross-cultural framework. It employed two global ethnographic samples, the Ethnographic Atlas (EA) and the Standard Cross-Cultural Sample (SCCS), and two subsets of the phylogeny (supertree) of human populations based on genetic and linguistic data, to investigate the variables that may have led to the introduction of these practices, and to determine where and when they may have originated. The study suggests that MGM/C probably originated in polygynous societies with separate residence for co-wives, supporting a mate-guarding function, and that FGM/C likely originated subsequently and almost exclusively in societies already practicing MGM/C, where it may have become a signal of chastity. Both practices are believed to have originated multiple times, some as early as in the mid-Holocene (5,000–7,000 years ago). The study posits that GM/C co-evolves with and may help maintain fundamental social structures and that the high fitness costs of FGM/C are offset by social benefits, such as enhanced marriageability and social capital.

  6. Human parental effort and environmental riskQuinlan, Robert J. - Proceedings of the Royal Society of Biological Sciences, 2007 - 2 Hypotheses

    This article tests the effect of environmental risk on parental investment, differentiating between maternal and paternal care. Results indicate that the saturation point of parental investment may be a function of environmental risk, as parental care experiences diminishing returns due to extrinsic risks.

  7. Human lactation, pair-bonds, and alloparents: a cross-cultural analysisQuinlan, Robert J. - Human Nature, 2008 - 1 Hypotheses

    This study examines the relationship between pairbonds and lactation, specifically the relationship between pairbond stability, alloparenting, and cross-cultural trends in breastfeeding. Findings show that both conjugal stability and availability of alloparental care are associated with age at weaning.

  8. Differences between tight and loose cultures: a 33-nation studyGelfand, Michele J. - Science, 2011 - 5 Hypotheses

    This article explores differences between "tight" cultures ("have many strong norms and low tolerance of deviant behavior") and "loose" cultures ("have weak social norms and high tolerance of deviant behavior"). The tightness-looseness measure manifests in a myriad of macro and micro phenomena, from governance and religiosity to individual psychological processes. This study investigates these phenomena in modern nations rather than traditional societies. Potential ecological, historical, and socio-political predictors of tightness-looseness are also examined.

  9. Institutionalized male transvestism, the couvade, and homosexual behaviorGray, J. Patrick - Ethos, 1984 - 2 Hypotheses

    This study employs a psychological theory and builds on the holocultural literature on male homosexuality. Two hypotheses relating homosexual behavior among men to social constructs for sexuality (the couvade, male transvestism) are derived from a study by Munroe (1980). The hypotheses are tested and supported in a sample of cultures drawn from Munroe's codes and the Human Relations Area Files.

  10. Parental certainty, subsistence and inheritance revisitedGray, J. Patrick - Journal of Human Evolution, 1981 - 2 Hypotheses

    This article examines the results of a study (Gaulin 1980) on male parental certainty and subsistence type. Methodological errors are assessed and the hypotheses are retested.
