Venom w/ Christie Wilcox

Cara chats remotely with Dr. Christie Wilcox, a conservation biologist and science writer. They focus on the topic of her new book, "Venomous," including the difference between venom and poison, the vast number of animals that have evolved venom as a predation or defensive mechanism, and how the toxins in venom are being used in modern medicine to treat a variety of diseases.
