David Quammen is an American science, nature and travel writer and the author of numerous books, including Song of the Dodo, The Reluctant Mr. Darwin, and Spillover, a stirring book about viruses going from humans from wildlife.  So, you might say he has been busy during this COVID pandemic. He was a columnist for Outside Magazine for 15 years, and his articles have also appeared in National Geographic, Harper's, Rolling Stone, the New Yorker and many others.  He has 3 National Magazine Awards.   Oh…and he’s a Rhode Scholar, and received a Guggenheim fellowship.  We are excited to talk to David today about his writings on Yellowstone National Park.
