Evolution of Venom

Generation Anthropocene

“In Asia or Africa around 60 million years ago, snakes became more venomous, though scientists aren't quite sure why then and there.” Sometimes understanding global environmental change requires that we simply know how nature works. And not just the pleasant side of nature, but all of it. When we look back through the wonders of Darwinian evolution, we gain a deeper appreciation for certain aspects of the natural world that seem… uncomfortable: things like snakes, spiders, jellyfish, Komodo Dragons, and tiny caterpillars that can easily kill humans. This week, scientist Christie Wilcox takes us on a journey through the evolution of the chemical cocktails we call “venom,” which she wrote about in her new book called, “Venomous: How Earth’s Deadliest Creatures Mastered Biochemistry.” Travel along from venom’s earliest formation, its evolution into a potent weapon, and its further transformation by doctors today as a potentially revolutionary tool in developing new medicines.
