In American schools, the Genesis creation narrative was generally taught as the origin of the universe and of life until Darwin's scientific theories became widely accepted. While there was some immediate backlash, organized opposition did not get underway until the Fundamentalist–Modernist controversy broke out following World War I; several states passed laws banning the teaching of evolution while others debated them but did not pass them. The Scopes Trial was the result of a challenge to the law in Tennessee. Scopes lost his case, and further U.S. states passed laws banning the teaching of evolution.
In 1968, the US Supreme Court ruled on Epperson v. Arkansas, another challenge to these laws, and the court ruled that allowing the teaching of creation, while disallowing the teaching of evolution, advanced a religion, and therefore violated the Establishment Clause of the US Constitution. Creationists then starting lobbying to have laws passed that required teachers to Teach the Controversy, but this was also struck down by the Supreme Court in 1987 in Edwards v. Aguillard. Creationists then moved to frame the issue as one of intelligent design but this too was ruled against in a District Court in Kitzmiller v. Dover Area School District in 2005. Since December 2005, Google Trends found the popularity of search queries for intelligent design in Google Search has declined sufficiently from its height in November 2004.[1]
As of 2024, all fifty US states and the District of Columbia includes the teaching of evolution in their public school science standards, while none teach intelligent design and creationism is discussed in non-science classes, such as philosophy, comparative religion, or current affairs.
