What is the theory of intelligent design?

The theory of intelligent design holds 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. (see What is intelligent design?)

Is intelligent design theory incompatible with evolution?

It depends on what one means by the word "evolution." If one simply means "change over time," or even that living things are related by common ancestry, then there is no inherent conflict between evolutionary theory and intelligent design theory. However, the dominant theory of evolution today is neo-Darwinism, which contends that evolution is driven by natural selection acting on random mutations, an unpredictable and purposeless process that "has no discernable direction or goal, including survival of a species." (NABT Statement on Teaching Evolution). It is this specific claim made by neo-Darwinism that intelligent design theory directly challenges.

Is intelligent design based on the Bible?

No. The idea that human beings can observe signs of intelligent design in nature reaches back to the foundations of both science and civilization. In the Greco-Roman tradition, Plato and Cicero both espoused early versions of intelligent design. In the history of science, most scientists until the latter part of the nineteenth century accepted some form of intelligent design, including Alfred Russel Wallace, the co-discoverer with Charles Darwin of the theory of evolution by natural selection. In the Judeo-Christian tradition, meanwhile, the idea that design can be discerned in nature can be found not only in the Bible but among Jewish philosophers such as Philo and in the writings of the Early Church Fathers. The scientific community largely rejected design in the early twentieth century after neo-Darwinism claimed to be able to explain the emergence of biological complexity through the unintelligent process of natural selection acting on random mutations. In recent decades, however, new research and discoveries in such fields as physics, cosmology, biochemistry, genetics, and paleontology have caused a growing number of scientists and science theorists to question neo-Darwinism and propose intelligent design as the best explanation for the existence of specified complexity throughout the natural world.

Is intelligent design theory the same as creationism?

No. Intelligent design theory is simply an effort to empirically detect whether the "apparent design" in nature acknowledged by virtually all biologists is genuine design (the product of an intelligent cause) or is simply the product of an undirected process such as natural selection acting on random variations. Creationism is focused on defending a literal reading of the Genesis account, usually including the creation of the earth by the Biblical God a few thousand years ago. Unlike creationism, the scientific theory of intelligent design is agnostic regarding the source of design and has no commitment to defending Genesis, the Bible or any other sacred text. Honest critics of intelligent design acknowledge the difference between intelligent design and creationism. University of Wisconsin historian of science Ronald Numbers is critical of intelligent design, yet according to the Associated Press, he "agrees the creationist label is inaccurate when it comes to the ID [intelligent design] movement." Why, then, do some Darwinists keep trying to conflate intelligent design with creationism? According to Dr. Numbers, it is because they think such claims are "the easiest way to discredit intelligent design." In other words, the charge that intelligent design is "creationism" is a rhetorical strategy on the part of Darwinists who wish to delegitimize design theory without actually addressing the merits of its case.
