Dozens of reasons have been proposed for the emergence of professional religious specialists in human history with little general consensus. Creating a global dataset of hunter-gatherers and using a novel method of exploratory phylogenetic path analysis, this study systematically identifies factors associated with the emergence of religious specialists. Results regarding existential insecurity were generally not supported. This study emphasizes the role of food storage as one of the only significant factors despite that it has been largely overlooked in the literature and theories. The results also highlight the need for more in-depth directional dependencies to better illustrate this evolution.
