  1. Agricultural societies will have higher paternal certainty than hunter-gatherer societies (230).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.

  2. Dowry will be associated with societies that are agricultural but have low female subsistance labor (1000).Gaulin, Steven J.C. - Dowry as female competition, 1990 - 3 Variables

    This study tests two models that predict the presence of dowry cross-culturally: the female competition model and the labor-value model. Results suggest that both models are predictive of dowry, however discriminant analysis finds the female competition model to be superior.

  3. There will be an association between type of subsistence and sexual dimorphism of stature (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.

  4. Polygyny will be positively related with degree of sexual stature dimorphism (471).Gaulin, Steven JC - Human marriage systems and sexual dimorphism in stature, 1992 - 2 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.

  5. 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

  6. Hunter-gatherers will experience more famine than those with other modes of subsistence (1).Berbesque, J. Colette - Hunter-gatherers have less famine than agriculturalists, 2014 - 2 Variables

    This study tests the common belief that hunter-gatherers suffer more famine than other subsistence types. Controlling for habitat quality, authors examine the relationship between famine and subsistence type and find that hunter-gatherers actually experience significantly less famine than other subsistence types.

  7. The type of food given to children during weaning was qualitatively different across subsistence types (p. 50).Sellen, Daniel W. - Relationships between subsistence and age at weaning in "preindustrial" soci..., 2001 - 2 Variables

    This study tests the weaning food availability hypothesis, that both the introduction of foods other than breastmilk and the cessation of breastfeeding will vary by society's subsistence type. This hypothesis has implications for demography, as accelerated weaning can lead to increases in both mothers' fertility (due to decreased birth intervals) and infant mortality (due to the presence of pathogens in new foods).

  8. Agricultural subsistence will be positively associated with inheritance to the wife's children; Hunter-gather subsistence will be positively associated with inheritance to individuals other than the wife's children (279)Gray, J. Patrick - Parental certainty, subsistence and inheritance revisited, 1981 - 3 Variables

    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.

  9. Agriculturalist populations will have lower infant and child mortality rates than hunter-gatherer populations.Volk, Anthony A. - Infant and child death in the human environment of evolutionary adaptation, 2013 - 3 Variables

    High infant and child mortality rates are suggested to be one of the most enduring and important features of ancestral human environments, referred to as the Environment of Evolutionary Adaptedness (EEA). These rates contrast with the very low rates of infant and child mortality among many industrialized nations since the 19th and 20th centuries. The authors compare data from recent hunter-gatherer and agricultural societies, historical records, and non-human primates in attempt to quantitatively describe infant and child mortality rates during the EEA.

  10. "Cassava will be more important where there are fewer food-getting strategies (less of a mix of subsistence strategies, wage labor, cash crops, government supplies, etc.); in turn food diversity will be positively associated with such cultural ecological variables as markets, access to markets, population density, and more elaborate technology" (p.101).Romanoff, Steven - Cassava production and processing in a cross-cultural sample of african soci..., 1992 - 7 Variables

    This exploratory study seeks to explain cassava production and processing in Africa by considering cultural, agronomic, and environmental data. After examining the descriptive results of the agricultural and social contexts of cassava use, the authors build upon Boserup's population density model (1965) to analyze their own hypothesized model of cassava's importance among the sampled societies.
