In July 1925, the Scopes “Monkey” Trial captivated the nation. On its face, the case was relatively straightforward: A Tennessee biology teacher named John Scopes was accused of teaching human evolution to his students. At the time, that was against state law. Both sides enlisted the help of big name lawyers to represent them, and the case turned into a national spectacle. But, why has the legacy of the case persisted? And what can it help us understand about our current moment?

Host Ira Flatow talks with Brenda Wineapple, author of Keeping the Faith: God, Democracy, and the Trial that Riveted a Nation. Read an excerpt of the book at sciencefriday.com.
