TOPEKA, Kan. - Risking the kind of nationwide ridicule it faced six years ago, the Kansas Board of Education approved new public-school science standards Tuesday that cast doubt on the theory of evolution. The 6-4 vote was a victory for “intelligent design” advocates who helped draft the standards. Intelligent design holds that the universe is so complex that it must have been created by a higher power. Critics of the new language charged that it was an attempt to inject God and creationism into public schools in violation of the separation of church and state.
