Edwards v. Aguillard, 482 U.S. 578 (1987), was a United States Supreme Court case concerning the constitutionality of teaching creationism. The Court considered a Louisiana law requiring that where evolutionary science was taught in public schools, creation science must also be taught. The constitutionality of the law was successfully challenged in District Court, Aguillard v. Treen, 634 F. Supp. 426 (ED La.1985), and the United States Court of Appeals for the Fifth Circuit affirmed, Aguillard v. Edwards, 765 F.2d 1251 (CA5 1985). The United States Supreme Court ruled that this law violated the Establishment Clause of the First Amendment because the law was specifically intended to advance a particular religion. In its decision, the court opined that "teaching a variety of scientific theories about the origins of humankind to school children might be validly done with the clear secular intent of enhancing the effectiveness of science instruction."
In support of Aguillard, 72 Nobel Prize-winning scientists, 17 state academies of science, and seven other scientific organizations filed amicus briefs that described creation science as being composed of religious tenets.
Creation–evolution controversy and Science versus religion
Modern American creationism arose from the theological split over modernist higher criticism and its rejection by the fundamentalist Christian movement, which promoted Biblical literalism and, post 1920, took up the anti-evolution cause led by William Jennings Bryan. The teaching of evolution had become a common part of the public school curriculum, but his campaign was based on the idea that "Darwinism" had caused German militarism and was a threat to traditional religion and morality. Several states passed legislation to ban or restrict the teaching of evolution. The Tennessee Butler Act was tested in the Scopes Trial of 1925, and continued in effect with the result that evolution was not taught in many schools.
