Timeline and Magnitude of Decline

On this, our 323rd Evolutionary Lens livestream, we discuss vultures, politics, and complex systems. Vultures, which have evolved multiple times (like mangroves, poison frogs, and “trees”), specialize on carrion. In India, a painkiller commonly used in people but toxic to vultures, diclofenac, came out of patent, began to be used in cattle, and the vast majority of vultures in India died. Downstream effects include the deaths of hundreds of thousands of people, and tens of billions of dollars in economic losses. Now in Africa, vultures are being poisoned intentionally, and a similar devastation is likely to happen. Vultures are ugly, smelly, and gross…and utterly central to the health of not just their ecosystems, but the people who live in and near them. Welcome to complex systems. Also: Katie Wilson, the mayor of Seattle, seems to be engaged in a kind of “scientific socialism,” akin to “scientific racism,” in which quasi-scientific ideas are used to justify (bad) policy.
