Shane joins evolutionary psychologist Debra Lieberman at the University of Miami to talk about her brand new book "Objection: Disgust, Morality, and The Law." In Part 1 we have a lively, deep, and funny conversation about the purpose of emotions, how our tastes and sexual preferences evolved, and which ways they drive us and why we find certain things taboo. It's a conversation so stimulating and entertaining, we had to make it two parts.
