Intelligent design is the claim that "certain features of the universe and of living things are best explained by an intelligent cause, not an undirected process such as natural selection." It is a modern form of the traditional teleological argument for the existence of God, modified to avoid specifying the nature or identity of the designer. Its primary proponents, all of whom are associated with the Discovery Institute, believe the designer to be God. Intelligent design's advocates claim it is a scientific theory, and seek to fundamentally redefine science to accept supernatural explanations.
