Please Explain: Pheromones

Our latest Please Explain is all about pheromones, chemicals released by animals that influence physiology or behavior, from how we communicate to how we choose mates. We'll be joined by Dr. Stuart Firestein, professor in the Department of Biological Sciences at Columbia University, and Dr. Tristram Wyatt, of the Department of Zoology, Oxford University, and author of Pheromones and Animal Behavior.
