  1. Male reproductive skew (proxy measure being incidence of paternal half-siblings) will be higher in societies at lower latitudes. (2)Ellsworth, Ryan M. - Comparative study of reproductive skew and pair-bond stability using genealo..., 2015 - 2 Variables

    Authors use genealogical data to investigate pair bond stability and reproductive skew across a sample of 80 small-scale societies. Results suggest that male reproductive skew and pair-bond stability are independent sources of cross-cultural variation in human mating patterns.

  7. "Teen birth rates will be lower at high latitudes" (30).Barber, Nigel - On the relationship between country sex ratios and teen pregnancy rates, 2000 - 2 Variables

    This study attempted to replicate earlier findings regarding population structure and teen pregnancy rates. Findings support the previous predictions that sex ratio, economic development, and latitude are all inversely related to teen birth rates.

  8. At lower latitudes there will be more ethnic groups in a region (974).Cashdan, Elizabeth - Ethnic diversity and its environmental determinants: effects of climate, pat..., 2001 - 2 Variables

    This article examines possible environmental predictors of ethnic diversity around the world. Results suggest that global ethnic diversity is associated with latitude, habitat diversity, pathogen stress, and climate.

  9. Infants will be healthier in societies located in higher latitudes than those located in lower latitudes (230).Whiting, Marjorie Grant - A Cross-Cultural Nutrition Survey of 118 Societies, Representing the Major C..., 1958 - 0 Variables

    Dietary variation has been implicated in population-level heath outcomes such as adult height and infant health. Here the author investigates these relationships in a sample of 118 nonindustrial societies, providing a comparative and quantitative assessment of nutrition and health cross-culturally.

  10. There will be a relationship between latitude and counting systems (343).Divale, William Tulio - Climatic instability, food storage, and the development of numerical countin..., 1999 - 2 Variables

    A model for the development of counting systems is tested. The hypothesis presented predicts that unpredictable climate conditions result in inconsistent food supply which leads to the need for food storage and, thus, a system to account for the stored food. Results strongly support this hypothesis.
