  1. 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.

  2. 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).
