Using phylogenetic methods, this research examines the relationship between landesque capital intensive agriculture ("permanent changes to landscape, such as construction of terraces and irrigation canals"(3631)) , political complexity, and social stratification amongst 155 Austronesian-speaking societies. Researchers attempted to find an underlying causality between the above mentioned variables, which have already been shown to be cross-culturally related. Results of statistical testing are most consistent with their being no clear causal link between the tested variables. The researchers claim this demonstrates social complexity and the multifaceted nature of cultural evolution.
