The society you live in can shape the complexity of your brain. For vertebrate animals like humans, and even birds and fish, there is a lot of support for the idea that our complex brains developed along with complex societies. Sean O'Donnell, a professor at Drexel University, explains how his lab studied whether this same pattern holds true for social insects--specifically, wasps. The answer to that question could mean a whole new way of thinking about how brains and social behavior can evolve together.
