  1. Association between geographic language area and various environmental variables will be stronger among pastoralists and foragers than among agriculturalists (7).Currie, Thomas E. - The evolution of ethnolinguistic diversity, 2012 - 6 Variables

    The authors test the relationship between ethnolinguistic area and various environmental variables in a cross-cultural sample of hunter-gatherer, pastoral, and agricultural subsistence groups in order to evaluate various hypotheses surrounding the geographic and ecological origins of cultural diversity. They propose that societies which adopted agriculture at the beginning of the Holocene were less directly affected by climate which, combined with the effect of increasing political and cultural complexity, allowed coordination and homogenization of ethnolinguistic groups over a broader swathe of territory.

  2. Geographic language area will be positively associated with net primary productivity among Australian and American foragers, but weakly or insignificantly associated with NPP among American agriculturalists (7).Currie, Thomas E. - The evolution of ethnolinguistic diversity, 2012 - 2 Variables

    The authors test the relationship between ethnolinguistic area and various environmental variables in a cross-cultural sample of hunter-gatherer, pastoral, and agricultural subsistence groups in order to evaluate various hypotheses surrounding the geographic and ecological origins of cultural diversity.

  3. Mobility of subsistence strategy will be positively associated with geographic language range (7340).Currie, Thomas E. - Political complexity predicts the spread of ethnolinguistic groups, 2009 - 2 Variables

    The researchers utilize a GIS approach in order to examine the relationship between global linguistic distribution and various cultural and environmental factors. The resulting positive association between political complexity and both latitude and language range leads the researchers to propose that large, politically complex entities exert a homogenizing pressure on language. However, the causal link may also be in the other direction, with possession of common language facilitating the creation of more complex political institutions.

  4. High land productivity variation will be associated with less language difference between neighboring ethnic groups.Dickens, Andrew - Understanding ethnolinguistic differences: The roles of geography and trade, 2021 - 2 Variables

    This paper examines the relationship of productive variation in land between ethnic groups to determine if an increased range of producible goods will increase trade, thus decreasing language diversity between neighboring groups. The author initially found that high-variation in land production lessened the diversity of language between ethnic groups in that area. To further test this correlation, the author found that high-productive variation increased trade and exogamous marriage and decreased inter-ethnic conflict. Based on these findings, the author suggests that neighboring ethnic languages co-evolved through the economic benefit of inter-ethnic trade and social interaction.

  5. Linguistic diversity will be predicted by some of 14 environmental variables across continental regions universally (2).Axelsen, Jacob Bock - River density and landscape roughness are universal determinants of linguist..., 2014 - 15 Variables

    The authors investigate the relationship between linguistic diversity and various environmental and spatial variables associated with biodiversity. Most of these variables predict linguistic diversity variably across different continents, and more so within Africa and extended Asia (Asia, the Pacific, and Australia) than within Europe and the Americas. This divide is theorized to be a result of differences in demography and impact of colonialism between the two global regions. However, two environmental factors, landscape roughness and density of river systems, are found to be significant predictors across all global regions. The authors suggest that, as in processes of speciation, rough terrain and watercourses both create physical barriers between which languages can develop in isolation while, in the case of river junctions, also providing transportation routes whereby hybrid languages can occasionally manifest.

  6. Relative reliance on consonants vs. vowels in human languages cross-culturally will be associated with different environments (5).Maddieson, Ian - Human language diversity and the acoustic adaptation hypothesis, 2015 - 10 Variables

    In the field of bioacoustics, the Acoustic Adaptation theory suggests that variation in vocalization across different species can be accounted for by the acoustic properties of different habitats. Here, the researchers test consonant- and vowel-heaviness in human languages against various environmental variables in order to examine the theory's potential application to our own species. The authors identify a significant negative correlation between consonant heaviness and temperature, precipitation, and tree cover, and some positive correlation with rugosity and elevation as their most important findings, while acknowledging the potentially influential roles of migration and demographic factors in producing this relationship.

  7. Risk of resource failure will influence toolkit structure (4).Collard, Mark - Causes of toolkit variation among hunter-gatherers: a test of four competing..., 2005 - 3 Variables

    This study tests four hypotheses that propose potential environmental and social predictors of toolkit size and complexity among hunter-gatherers. Hypotheses predicting relationships between population size, residential mobility, type of food resources and toolkit structure are not supported. Risk of resource failure is the only variable that is significantly associated with toolkit structure.

  8. Agriculture will be more common in high-productivity regions when compared to non-agricultural subsistence activities.Dickens, Andrew - Understanding ethnolinguistic differences: The roles of geography and trade, 2021 - 2 Variables

To further test this correlation, the author found that high-productive variation increased trade and exogamous marriage and decreased inter-ethnic conflict. Based on these findings, the author suggests that neighboring ethnic languages co-evolved through the economic benefit of inter-ethnic trade and social interaction.
