Charles Darwin’s Lesser-Known Eccentric Exploits

Before he became famous for his theory of evolution, Charles Darwin spent years observing barnacle species from around the world, playing music to earthworms, and feeding bits of raw meat to insectivorous plants in an attempt to stimulate them. In his new book, Darwin’s Backyard, biologist James Costa talks about how these and other lesser-known experiments brought Darwin closer to his big theory of evolution. [Recreate Darwin’s experiments in your backyard.] Costa joins Ira to talk about what these experiments reveal about how Darwin interpreted the world. Plus, biologist Dean Pentcheff of the Natural History Museum of Los Angeles County discusses how Darwin’s work on barnacles influences what we know about them today. Plus, neuropsychologist Peter Snyder joins Ira to talk about how he dug into Darwin’s handwritten archives and discovered a psychology experiment that challenged the idea of how people express and recognize emotions in the faces of other people. James Costa James Costa is the author of “Darwin’s Backyard: How Small Experiments Led to a Big Theory” (W. W. Norton & Company, 2017). He’s also the director of the Highlands Biological Station and a professor of biology at Western Carolina University. He’s based in Cullowhee, North Carolina.
