In 1968, the U.S. Supreme Court invalidated a 1928 Arkansas law criminalizing the teaching of evolution in public or state-supported schools of that state. The landmark ruling in Epperson v. Arkansas, was held 9-0. Arkansas’ law violated the First Amendment’s Establishment Clause, which proscribes legislation to favor the tenets of a particular religion. The Court found that the goal of the law was to restrict teachers from introducing the theory of evolution, as contrary to the belief of Christian Fundamentalists, that Genesis was the exclusive doctrine for humanity’s origin. The law was modeled on the Tennessee Butler Act (1925). The case was filed by a Little Rock teacher, Susan Epperson, and parent, H.H. Blanchard.«
