Intelligent design (ID) is the concept that the universe and living things have features that could only have been designed by an intelligent cause or agent, as opposed to an unguided process such as natural selection. Leading proponents, of which all are affliated with the Discovery Institute, say that intelligent design is a scientific theory that stands on equal footing with, or is superior to, current scientific theories regarding the origin of life.
An overwhelming majority of the scientific community views intelligent design not as a valid scientific theory but as pseudoscience or junk science.
 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.
United States federal courts have ruled as unconstitutional a public school district requirement endorsing intelligent design as an alternative to evolution in science classes, on the grounds that its inclusion violates the Establishment Clause of the First Amendment. In Kitzmiller v. Dover Area School District (2005) United States federal court judge John E. Jones III ruled that intelligent design is not science and is essentially religious in nature.
