Our guest on today’s Modern Notion Daily is Andrew Moore, author of Pawpaw: In Search of America’s Forgotten Fruit (Chelsea Green, August 2015). Moore discovered the pawpaw, which is native to the United States, five years ago in a grove in Ohio. Despite its addictive taste and aroma (it’s been called a cross between a banana and a mango), the pawpaw never achieved mass appeal. Moore explores the reasons and talks about his adventures going pawpaw pickin’. Also, at the top of the show, Pam Wasserman from Population Connection tells us about the invention of microscopes and how that’s affected world population. You can check out Population Connection’s interactive map/timeline at www.worldpopulationhistory.org. And later in the hour, contributing editor Mark Hay tells the story of a penguin named Lala who wore a backpack.
