In this article, the authors seek to determine cross-culturally valid predictors of dominant types of human subsistence around the world. They did this by formulating multiple models that incorporate different combinations of environmental, geographic, and social factors. These models were then used to test various hypotheses posed throughout the anthropological literature surrounding factors that determine dominant subsistence strategies.


Most of the factors tested in this paper (environmental productivity, environmental stability, varied topography, political complexity, contact with neighbors) had contrary hypothesized relationships in the literature. For clarity, we list the hypothesized relationships that were supported if possible. The overall R^2 GLMM for the average model is 0.86.
