The vast majority of the scientific community and academia supports evolutionary theory as the only explanation that can fully account for observations in the fields of biology, paleontology, anthropology, and others.[16][17][18][19][20] One 1987 estimate found that "700 scientists ... (out of a total of 480,000 U.S. earth and life scientists) ... give credence to creation-science".[21] An expert in the evolution-creationism controversy, professor and author Brian Alters states that "99.9 percent of scientists accept evolution".[22] A 1991 Gallup poll of Americans found that about 5% of scientists (including those with training outside biology) identified themselves as creationists.[23][24]
Additionally, the scientific community considers intelligent design, a neo-creationist offshoot, to be unscientific,[25] pseudoscience,[26][27] or junk science.[28][29] The U.S. National Academy of Sciences has stated that intelligent design "and other claims of supernatural intervention in the origin of life" are not science because they cannot be tested by experiment, do not generate any predictions, and propose no new hypotheses of their own.[30] In September 2005, 38 Nobel laureates issued a statement saying "Intelligent design is fundamentally unscientific; it cannot be tested as scientific theory because its central conclusion is based on belief in the intervention of a supernatural agent."[31] In October 2005, a coalition representing more than 70,000 Australian scientists and science teachers issued a statement saying "intelligent design is not science" and calling on "all schools not to teach Intelligent Design (ID) as science, because it fails to qualify on every count as a scientific theory".[32]
