A natural history of infidelity and a history of science on the topic. Listen and learn about the oldest known laws in history, fish that get pessismistic without their boyfriend, the costs of monogamy, the ovulatory shift hypothesis (and a conspiracy theory about it), the mate-switching vs. dual-mating debate, and so much more.
