A University of Idaho professor testified in favor of "intelligent design" this week, as a landmark trial over the use of the theory in a Pennsylvania school district drew to a close. Scott Minnich, a microbiologist at UI, testified Thursday and Friday on behalf of the Dover, Pa., Area School Board, which voted in 2004 to require students to hear a statement about intelligent design and "gaps" in the theory of evolution in biology classes. Eight families are suing, saying the policy violates the constitutional ban on state promotion of religion because it essentially promotes a biblical view of creationism.
