The Scopes Trial and the Creation-Evolution Debate

Governor Austin Peay signed the Butler Act, making it unlawful for teachers in state-funded schools to deny the biblical account of creation or to teach that humans had descended from other forms of life. The act was promoted by state legislator John W. Butler and by fundamentalist organizations who argued that public schools, funded by Christian taxpayers, should not teach contrary to Scripture. Modernists and the American Civil Liberties Union saw the law as a test case waiting to happen.

After the ACLU advertised in Tennessee newspapers offering to fund a legal challenge to the Butler Act, a group of Dayton businessmen saw an opportunity to bring attention to their town and recruited John T. Scopes, a 24-year-old high school teacher and football coach, to stand trial. Scopes was unsure whether he had actually taught evolution but deliberately incriminated himself so the challenge could proceed. He was charged in May 1925.

The trial of State of Tennessee v. John Thomas Scopes opened before Judge John Tate Raulston, with three-time presidential candidate and former secretary of state William Jennings Bryan joining the prosecution and Clarence Darrow leading the defense for the ACLU. The proceedings drew national press and became the first American trial broadcast nationally by radio. The defense sought to challenge the law's constitutionality; the prosecution sought to defend the right of a state to set its school curriculum.

On the trial's seventh day, proceedings were moved outdoors because of excessive heat, and Clarence Darrow called William Jennings Bryan as an expert on the Bible and questioned him for hours on literal interpretations of Scripture, including the creation days and the story of Jonah. The exchange was widely reported as a contest between religious fundamentalism and modern critical thought; defenders of Bryan argued the questioning mocked sincere belief, while supporters of the defense saw it as a legitimate test of enforcing literalism by law.

After nine minutes of deliberation the jury found Scopes guilty, and Judge Raulston fined him 100 dollars, the minimum penalty under the statute introduced by Bryan himself. The defense's constitutional arguments had been excluded from the record, leaving the central legal question unresolved. Scopes's lawyers announced an appeal to the Tennessee Supreme Court.

Five days after the verdict, Bryan died in his sleep in Dayton after a heavy meal in the Tennessee heat. Mourned by supporters as a champion of ordinary citizens against elite expertise, he was buried at Arlington National Cemetery. His death fixed the trial in public memory as a symbolic close to an era, though anti-evolution activism continued at school boards and legislatures across the country.

The Tennessee Supreme Court overturned Scopes's conviction on a technicality, ruling that the fine should have been set by the jury rather than the judge, and returned the case with the prosecution declining to retry it. The court left the Butler Act standing and did not rule on its constitutionality, so the legal questions the ACLU had raised remained unanswered for decades. The act stayed on the books in Tennessee until 1967.

The United States Supreme Court unanimously struck down an Arkansas statute prohibiting the teaching of evolution, ruling that a state may not prescribe religious orthodoxy in public school instruction. The decision invalidated anti-evolution laws modeled on the Butler Act across the country. The court reasoned that the First Amendment does not permit a state to bar teaching a scientific theory because it conflicts with a particular religious view.

A federal district court struck down Arkansas's Act 590 requiring "balanced treatment" of creation science and evolution in public schools. Judge William Overton's opinion set out criteria for what constitutes science, including testability and tentativeness, and concluded that creation science failed them and advanced a particular religious belief. The ruling became a template for challenges to similar laws in other states.

The United States Supreme Court ruled 7-2 that Louisiana's Balanced Treatment for Creation-Science and Evolution-Science Act violated the establishment clause, finding its purpose was to promote a particular religious belief. The ruling closed the statutory path for creation science in public schools. Advocates of alternatives to evolution subsequently reframed their case around "intelligent design", setting up the next round of litigation.

Federal judge John E. Jones III ruled that the Dover Area School District's policy requiring intelligent design to be presented in biology classes violated the establishment clause, concluding after a six-week trial that intelligent design was a religious argument rather than science. Parents and science teachers had challenged the policy while the Thomas More Law Center defended it. The ruling was the first direct federal decision on intelligent design in public schools.
