The little town of Dayton - not far from where Katz and I now sat, as it happened - was the scene of the famous Scopes trial in 1925, when the state prosecuted a schoolteacher named John Thomas Scopes for rashly promulgating Darwinian hogwash. As nearly everyone knows, Clarence Darrow, for the defense, roundly humiliated William Jennings Bryan, for the prosecution, but what most people don't realize is that Darrow lost the case. Scopes was convicted, and the law wasn't overturned in Tennessee until 1967. And now the state was about to bring the law back, proving conclusively that the danger for Tennesseans isn't so much that they may be descended from apes as overtaken by them.
