Why is the Scopes Trial more than just a debate about Creation vs Evolution and how it became historically significant in the 1920s era? (please evaluate on the extends of racial issues, modernism vs. fundamentalism, and other social issues)

The facts of the Scopes Trial of 1925 are fairly straightforward. Tennessee had passed a law prohibiting the teaching of evolution. The American Civil Liberties Union (ACLU) was eager to challenge Tennessee's law. The ACLU persuaded a high-school teacher, John Scopes, to admit to teaching evolution and to stand trial. Both sides had famous lawyers: William Jennings Bryan for the prosecution and Clarence Darrow for the defense. The trial included long debates over the Bible and a lot of publicity. But there was no doubt that Scopes had taught evolution, and he was found guilty and fined $100—a large sum in 1925. Tennessee's law was not repealed until 1967, and schools across the nation avoided teaching evolution for decades after 1925.
In a broader sense, the trial represented a clash between a modern and conservative groups in American society. This struggle was evident before the Scopes Trial. The Jazz Age of the twenties represented a new era while the Volstead Act (1919) had ushered in an era of Prohibition. H.L. Mencken, a famous journalist who reported on the Scopes Trial, was contemptuous of Tennessee's law, its people, and Bryan: "As I have said, Bryan understands these peasants, and they understand him. I have met no educated man who is not ashamed of the ridicule that has fallen upon the State."
