  1. Human marriage systems and sexual dimorphism in statureGaulin, Steven JC - American journal of physical anthropology, 1992 - 2 Hypotheses

    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. Correlations in the population structure of music, genes and languageBrown, Steven - Proc. R. Soc. B, 2014 - 6 Hypotheses

    By testing relationships between musical, geographic, genetic, and linguistic distance among nine indigenous groups in Taiwan, the researchers aim to quantitatively evaluate a developing theory of coevolution between these traits. An especially strong correlation between musical variability and genetic distance suggests that music may possess worldwide time depth, diversity, and universality equal to or greater than that of language, and could thus serve as a complementary marker for reconstruction of long-term population shifts.

  4. Sexual dimorphism in the human post-reproductive life-span: possible causesGaulin, Steven J.C. - Journal of Human Evolution, 1980 - 2 Hypotheses

    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.

  5. Cross-cultural differences in sexual dimorphism: is there any variance to be explained?Gaulin, Steven J.C. - Ethnology and Sociobiology, 1985 - 0 Hypotheses

    This study retests data on sexual dimorphism of body size from the Wolfe and Gray (1982) study. The authors challenge previous explanations for variation in sexual dimorphism across cultures. They find that there is a consistent level of sexual dimorphism across cultures, regardless of cultural traits or average body size.

  6. Dowry as female competitionGaulin, Steven J.C. - American Anthropologist, 1990 - 2 Hypotheses

    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.

  7. Punishment and social organization: a study of durkheim's theory of penal evolutionSpitzer, Steven - Law & Society Review, 1975 - 5 Hypotheses

    This study empirically tests Durkheim’s theories of punishment in a sample of preindustrial societies. Analysis shows little support for five hypotheses derived from Durkheim’s theories. Findings indicate that in preindustrial societies, the intensity of punishment is associated with political integration, there are fewer collective definitions of crime, there is a higher likelihood of using material sanctions; additionally, slavery is likely to be an institutionalized means of punishment in societies with harsher sanctions.

  8. Commentary:Cassava and African food security: Some ethnographic examplesRomanoff, Steven - Ecology of Food and Nutrition, 1992 - 0 Hypotheses

  9. Cassava production and processing in a cross-cultural sample of african societiesRomanoff, Steven - Behavior Science Research, 1992 - 12 Hypotheses

    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.

  10. Pathogen prevalence and human mate preferencesGangestad, Steven W. - Ethnology and Sociobiology, 1993 - 1 Hypotheses

    This study focuses on the relationship between pathogen prevalence and mate selection. Results show that increased pathogen prevalence is significantly associated with an increased importance in the physical attractiveness of potential mates.
