Patreon: https://bit.ly/3v8OhY7 Deborah Gordon is Professor of Biology at Stanford University. She is a myrmecologist—an entomologist who studies ants—focusing on how complex behavior emerges from ant colonies, which have no central control. In this episode, Deborah and Robinson discuss some of the distinctive features of ants, how pheromones help to determine their behavior, examples of fascinating ant species, collective ant behavior, and the life cycle of an ant colony. For more of Deborah’s work on collective behavior, check out her book The Ecology of Collective Behavior (Princeton, 2023).
