This has been the summer of "intelligent design." In August, President Bush endorsed this revamped version of creationism, and this week a Pew Forum poll found that fewer than half of Americans accept Darwin's theory of evolution. This widespread rejection of seemingly established truths has shocked many observers. After all, didn't the Scopes trial resolve this 80 years ago?
The anniversary of the "Monkey Trial" provides an occasion to remember that it didn't really settle what we assume it settled. Popular memory of the trial, reinforced by the 1960 movie Inherit the Wind, made it seem that evolution was triumphant and fundamentalism vanquished, but in fact the result was much more ambiguous. Anti-Darwinism didn't die in Dayton, Tenn., in July 1925—it just retreated temporarily from the national scene, to which it has now returned.
Like the 1960s, the 1920s witnessed a series of culture wars. After decades in which liberalism and science had gained popular acceptance, a backlash arrived in the '20s. A revived Ku Klux Klan swelled to 5 million members. Feminism, having secured women's suffrage, stalled. The 18th Amendment, passed in 1919, prohibited the sale of alcohol. Congress restricted the immigration of peoples deemed undesirable.
Evolution marked another front in these fights. Although Darwin's theories had met fierce resistance when first proposed in 1859, in time they secured general approval. Even many Christian leaders, once hostile to evolution, endorsed the theory—one of several trends that split many Protestant denominations into modern (or liberal) and fundamentalist camps. "By the time of World War I," wrote the historian William Leuchtenberg, "an attack on Darwin seemed as unlikely as an attack on Copernicus."
But attack the fundamentalists did. Advocating a literal reading of the book of Genesis, they attained political power in many states, particularly in the rural South and Great Plains. In Tennessee, Oklahoma, and Mississippi, they passed laws forbidding the teaching of evolution.
In Tennessee, the recently formed American Civil Liberties Union recruited teachers to challenge the so-called Butler Act, which banned teaching "any theory that denies the story of divine creation of man as taught in the Bible." John T. Scopes, a slight, sandy-haired 24-year-old biology instructor at Central High School in Dayton, volunteered. Scopes, reported to the police by a friend for his transgression and promptly arrested, with the help of the ACLU retained a trio of eminent lawyers, including Clarence Darrow (whose recent defense of the brutal child-killers Leopold and Loeb hardly endeared him to pious Tennesseans). Aiding the prosecution was the thrice-failed Democratic presidential candidate and former Secretary of State William Jennings Bryan, a leader in the anti-evolution movement, who promised a "duel to the death."
And so in July 1925 the Monkey Trial became a national obsession and a media circus. Partisans and reporters invaded Dayton. Horse-drawn carriages, mule-led wagons, and Model T Fords choked the small town's narrow streets. Owners of chimpanzees and monkeys hurried downtown for photo opportunities, while flappers sparked a short-lived fashion trend by donning simian stoles. Radio, rapidly spreading into American homes, brought the trial to people's firesides, and newsreels showed it to moviegoers.
In the courtroom, Scopes never stood a chance: He had broken the law. Instead, the ACLU hoped to send the case up to the U.S. Supreme Court to review the law's constitutionality. The real fight in Dayton was for public opinion.
The trial's turning point came when, in an unorthodox move, Scopes' lawyers got Bryan to take the stand. Darrow declared that he intended to "prevent bigots and ignoramuses from controlling the educational system of the United States." Darrow quizzed Bryan on his beliefs, humiliating the onetime hero. Bryan confessed that he believed in the literal truth of such biblical tales as Joshua making the sun stop in the sky, while also conceding, contradictorily, that scriptural passages could be interpreted as metaphorical. The crowd roared with laughter at his confused answers. (In a sad coda, Bryan fulfilled his promise of a duel to the death, succumbing to a fatal heart attack five days after the verdict.)
Bryan's faltering performance—along with the withering reportage of critics like H.L. Mencken, who mocked Dayton's "yokels" and "hookworm carriers"—caused the trial to be seen, simplistically, as a battle between enlightened science and backward religion. In this telling, Scopes technically lost but science and cosmopolitanism actually won. For although the case never reached the U.S. Supreme Court—the Tennessee Supreme Court overturned the guilty verdict on a technicality—federal jurisprudence embraced the idea that evolution was fact, worthy of teaching in public schools, and creationism was religion, unfit for the science classroom.
