  1. Among foragers, mobility frequency will be negatively associated with technological diversity (23, 33).Shott, Michael - Technological organization and settlement mobility: an ethnographic examination, 1986 - 2 Variables

    This study tests the relationship between mobility and technology among foragers, with the intent of applying findings to the archaeological record. In data analysis, mobility frequency is differentiated from mobility magnitude, and technological diversity is differentiated from technological complexity. Results suggest that mobility frequency is negatively associated with technological diversity while mobility magnitude is negatively associated with technological complexity.

  2. Technological complexity is negatively associated with residential mobility (2).Collard, Mark - Risk, mobility or population size?: Drivers of technological richness among ..., 2013 - 2 Variables

    This paper builds off previous research into the effect of population size and resource risk on complexity of subsistence technology by investigating the relationship between these independent variables and total number of material items and techniques used by various western North American hunter-gatherer groups. This tally of total technological complexity is found to be insignificantly related to population size or residential mobility; however, there is a significant correlation in the expected direction between technological complexity and one measure of resource risk (mean annual temperature during driest month). Tying this finding to previous analyses of subsistence technologies, the authors theorize that environmental risk is a pervasive driver of technological ingenuity and cultural evolution.

  3. Diversity and complexity of toolkits used by farming and herding groups will be positively associated with risk of resource failure (2).Collard, Mark - Risk of resource failure and toolkit variation in small-scale farmers and he..., 2012 - 11 Variables

    Prior research by Oswalt (1973, 1976) and Torrence (1983, 2001) has suggested that risk of resource failure is a significant predictor of toolkit complexity and diversity among hunter-gatherers. In this paper, the same relationship is tested among small-scale herding and farming groups. However, no significant correlation is discovered between any measure of resource risk and any measure of toolkit complexity. The researchers suggest that this absence may be the result of greater reliance on non-technological diversification methods among farmers (i.e. spatial diversification, mixed farming, intercropping), or of other unaccounted-for sources of risk (i.e. intergroup raiding and warfare).

  4. Toolkit complexity and diversity will be positively associated with population size (253).Collard, Mark - Niche construction and the toolkits of hunter–gatherers and food producers, 2011 - 3 Variables

    The researchers test the relationship between toolkit complexity and diversity as defined by Oswalt (1973) and environmental and demographic variables. Neither population size nor risk of resource failure predict toolkit characteristics among all groups in the sample. However, population size is significantly positively correlated with toolkit diversity and complexity among food-producers, whereas environmental factors indicating risk of resource failure are significantly positively correlated among hunter-gatherers. This leads the researchers to suggest that food-producers' effectiveness at niche construction is a result of their large population size, which thus has a larger effect on toolkit composition than does environmental risk relative to hunter-gatherers.

  7. An ordered category of mode of marriage (from gift exchange to dowry) will be associated with general scales of evolution (subisstence type, societal complexity, and settlement pattern).Schaefer, James Michael - Data quality and modes of marriage: some holocultural evidence of systematic..., 1976 - 4 Variables

    Authors explore the problem of data quality control, systematic error and spurious correlations possibly caused by systematic errors in global cross-cultural studies. They offer a solution (the use of control variables investigating potential sources of systematic error) and apply the technique to a cross-cultural study of the substantive correlates of societal organization and modes of marriage.

  8. Technological complexity is positively associated with risk of resource failure (1).Collard, Mark - Risk, mobility or population size?: Drivers of technological richness among ..., 2013 - 6 Variables

    This paper builds off previous research into the effect of population size and resource risk on complexity of subsistence technology by investigating the relationship between these independent variables and total number of material items and techniques used by various western North American hunter-gatherer groups.

  9. Number of residential moves per year will be negatively associated with percent contribution to diet through fishing and positively associated with percent contribution to diet through hunting and gathering (61).Marlowe, Frank W. - Hunter-gatherers and human evolution, 2005 - 4 Variables

    This article explores the relationships between habitat and social organization among humans and other species. Diet, technology, group size, home range, mobility, kinship, marital residence, sexual division of labor, mating system, central places, food sharing, and egalitarianism are all considered.

  10. Language diversity among Pacific islands will be positively associated with large land area, low distance from closest continent, and duration of human settlement (959).Gavin, Michael C. - The island biogeography of languages, 2012 - 4 Variables

    This paper examines the enormous variation in linguistic diversity among Pacific Islands by testing its relationship with various environmental variables put forth in several common theories of language richness. The researchers identify variables relating to land area and island isolation as accounting for about half of variation in linguistic diversity, suggesting that the other half is a result of complex social factors.
