Jad Abumrad and Robert Krulwich have a new episode of Radiolab airing this week. The theme of the show is heredity and its attendant mysteries. I had great fun telling the strange and tragic story of the early twentieth century biologist Paul Kammerer, who thought he could change the human race with the help of a midwife toad. (Some of my favorite sources about this tale and its present-day reverberations are here, here, here, here, here, and here.)
Science writer Sam Kean joins the Radiolab crew as well, along with some scientists doing fascinating work on mother rats licking baby rats, Swedes surviving harsh winters, and more.
Added bonus: my daughters Charlotte and Veronica helped read the program credits. They get their ability to pronounce “Jad Abumrad” from me.
