The researchers, using principal component analysis, generalized additive models across 12 agriculture origin locations, and a model predicting hunter-gatherer population density, evaluate hindcasted population density trends to suggest predictors of the development of agriculture. Using domestication as an indicator of agriculture, they test 3 competing hypotheses regarding agriculture development. Their results are consistent with the "surplus" hypothesis, indicating that agriculture arose as population densities increased along with environmental capabilities.

In this study, the authors draw from intensity theory and combine previous research from the fields of behavioral ecology, economics, and social evolution to analyze drivers in the emergence and persistence of inequality across the world. They propose that environmental heterogeneity and circumscription (the difficulty of moving and establishing oneself in a new environment relative to remaining in the current one) play a significant role in the stratification of societies. Their results indicate that situations arise from various environmental conditions and levels of circumscription that may result in an individual giving up autonomy for material gain, thus favoring inequality.

Using multiple logistic regression, the researchers compare the relative strength of predictors of land ownership across 102 societies. The analysis finds significant predictive power in factors such as neighbors' property system, population density, and geography.
