- The global pattern of mandibular morphology variation will be associated with dichotomized (hunter/gatherer vs. agricultural/pastoralist) subsistence type (19546).von Cramon-Taubadel, Noreen - Global human mandibular variation reflects differences in agricultural and h..., 2011 - 2 Variables
The researchers test the relationship between global mandibular morphology variation and susbsistence economy, population history, geography, and climate. While some mandibular variation is significantly correlated with geography, the most significant relationship is with subsistence activity. The strength of the relationship leads the authors to speculate on how masticatory behavior might have affected jaw shape, either through stress, weaning behavior, or other demographic factors.

Using a representative sample of 339 hunter-gatherer societies, researchers examine the relationship between hunter-gatherer use of space, size of population and supply of resources to see if they are similar to other organisms. By combining all factors into a single model, the authors claim to explain 86% of the variation in home range. Hunters have greater resource distribution than gatherers but both more so than aquatic foragers. Lastly, terrestrial foragers have more extensive home ranges than aquatic foragers.

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.

The myths, legends, and folktales of nearby groups tend to more alike than those of more distant groups. Three competing models attempt to explain this distribution of cultural traits: (1) vertical transmission, (2) horizontal transmission, and (3) independent innovation. The authors examine 18 Arctic hunter-gatherer groups to quantify the extent to which geographic distance, cultural ancestry, and effective population size predict overlap in folktale inventories.
