"Scientists take evolution fight online. National Academies sets up Web site to defend theory" (2005)

The Web site carries links to various reports on evolution, which some U.S. religious groups want to be taught in schools only if their own views of a divine creator get equal credence.

"The theory of evolution is one of science's most robust theories, and the National Academies have long supported the position that evolution be taught as a central element in any science education program," the Academies said in a statement.

"Over the past several years, however, there has been a growing movement around the country to include non-scientifically based 'alternatives' in science courses," it added.

"Currently there are challenges to the teaching of evolution in some 40 states or local school districts."

Some of these are detailed by the National Center for Science Education, a non-profit organization dedicated to keeping evolution in public school education, at its Web site.

The National Academies is an independent organization that routinely provides guidance on scientific, medical and engineering questions to the federal government and other groups that may ask them.
