more confident in evolution as the central defining principle of biology, American membership in churches favoring increasingly literal interpretations of scripture also rose, with the Southern Baptist Convention and Lutheran Church–Missouri Synod outpacing all other denominations. With growth and increased finances, these churches became better equipped to promulgate a creationist message, with their own colleges, schools, publishing houses, and broadcast media. In 1961 Presbyterian and Reformed Publishing released the first major modern creationist book: John C. Whitcomb and Henry M. Morris' influential The Genesis Flood: The Biblical Record and Its Scientific Implications. The authors argued that creation was literally 6 days long, that humans lived concurrently with dinosaurs, and that God created each "kind" of life individually. On the strength of this, Morris became a popular speaker, spreading anti-evolutionary ideas at fundamentalist churches, colleges, and conferences. Morris' Creation Science Research Center (CSRC) rushed publication of biology textbooks that promoted creationism. Ultimately, the CSRC broke up over a divide between sensationalism and a more intellectual approach, and Morris founded the Institute for Creation Research, which was promised to be controlled and operated by scientists. During this time, Morris and others who supported flood geology adopted the terms "scientific creationism" and "creation science". The "flood geology" theory effectively co-opted "the generic creationist label for their hyperliteralist views." Court cases McLean v. Arkansas In 1982, another case in Arkansas ruled that the Arkansas "Balanced Treatment for Creation-Science and Evolution-Science Act" (Act 590) was unconstitutional because it violated the Establishment Clause. Much of the transcript of the case was lost, including evidence from Francisco Ayala. Edwards v. Aguillard In the early 1980s, the Louisiana legislature passed a law titled the "Balanced Treatment for Creation-Science and Evolution-Science Act". The act did not require teaching either evolution or creationism as such, but did require that when evolutionary science was taught, creation science had to be taught as well. Creationists had lobbied aggressively for the law, arguing that the act was about academic freedom for teachers, an argument adopted by the state in support of the act. Lower courts ruled that the State's actual purpose was to promote the religious doctrine of creation science, but the State appealed to the Supreme Court. In the similar case of McLean v. Arkansas (see above) the federal trial court had also decided against creationism. Mclean v. Arkansas was not appealed to the federal Circuit Court of Appeals, creationists instead thinking
