INTELLIGENT DESIGN

President Bush waded into the debate over evolution and "intelligent design" Monday, saying schools should teach both theories on the creation and complexity of life.

Bush declined to state his personal views on "intelligent design," the belief that life forms are so complex that their creation can't be explained by Darwinian evolutionary theory alone, but rather points to intentional creation, presumably divine.

Scientists concede that evolution doesn't answer every question about the creation of life, but most consider intelligent design an attempt to inject religion into science courses.

"I think that part of education is to expose people to different schools of thought," Bush said. " You're asking me whether or not people ought to be exposed to different ideas, the answer is yes."

The National Academy of Sciences and the American Association for the Advancement of Science have both concluded that there's no scientific basis for intelligent design and oppose its inclusion in school science classes.

"The claim that equity demands balanced treatment of evolutionary theory and special creation in science classrooms reflects a misunderstanding of what science is and how it is conducted," the academy said in a 1999 assessment. "Creationism, intelligent design, and other claims of supernatural intervention in the origin of life or of species are not science because they are not testable by the methods of science."
