found in the Precambrian era, a time before most similarly complex lifeforms had evolved, "that would completely blow evolution out of the water." Falsifiability has caused problems for creationists: in his 1982 decision McLean v. Arkansas Board of Education, Judge William R. Overton used falsifiability as one basis for his ruling against the teaching of creation science in the public schools, ultimately declaring it "simply not science." Conflation of science and religion Creationists commonly argue against evolution on the grounds that "evolution is a religion; it is not a science," in order to undermine the higher ground biologists claim in debating creationists, and to reframe the debate from being between science (evolution) and religion (creationism) to being between two equally religious beliefs—or even to argue that evolution is religious while intelligent design is not. Those that oppose evolution frequently refer to those who accept evolution as "evolutionists" or "Darwinists." This is generally argued by analogy, by arguing that evolution and religion have one or more things in common, and that therefore evolution is a religion. Examples of claims made in such arguments are statements that evolution is based on faith, that supporters of evolution revere Darwin as a prophet and dogmatically reject alternative suggestions out-of-hand. These claims have become more popular in recent years as the neocreationist movement has sought to distance itself from religion, thus giving it more reason to make use of a seemingly anti-religious analogy. In biology, no scientist's claims, including Darwin's, are treated as sacrosanct, as shown by the aspects of Darwin's theory that have been rejected or revised by scientists over the years, to form first neo-Darwinism and later the modern evolutionary synthesis. Appeal to consequences A number of creationists have blurred the boundaries between their disputes over the truth of the underlying facts, and explanatory theories, of evolution, with their purported philosophical and moral consequences. This type of argument is known as an appeal to consequences, and is a logical fallacy. Examples of these arguments include those of prominent creationists such as Ken Ham and Henry M. Morris. Disputes relating to science Many creationists strongly oppose certain scientific theories in a number of ways, including opposition to specific applications of scientific processes, accusations of bias within the scientific community, and claims that discussions within the scientific community reveal or imply a crisis. In response to perceived crises in modern science, creationists claim to have
