Normativity is widely regarded as the ability to make evaluative judgments based on a shared system of social norms. When normativity is viewed through the cognitively demanding lens of human morality, however, the prospect of finding social norms innonhuman animals rapidly dwindles and common causal structures are overlooked. In this paper, I develop a biofunctionalist account of social normativity and examine its implications for how we ought to conceptualize, explain, and study social norms in the wild. I propose that we (...) think of social normative systems as behavior-regulatory power structures that resolve conflicts between nested levels of selection in favor of the higher level. I argue that the best case for social norms outside of humans is not in the animals one might expect, such as primates or other large-brained vertebrates, but rather in social insects. Finally, I engage with a number of potential objections to this unorthodox proposal. (shrink)
