Debates over evolution range from Pennsylvania to Kansas to the University of California. Michael Shermer, a former evangelical Christian and creationist, argues that “intelligent design” theory appeals to a human predisposition to look for a designer behind life’s complexity. But in fact the theory of natural selection is supported by the scientific evidence and is the foundation on which modern biology rests. Conservatives and Christians should accept evolution because it explains family values, social harmony, human nature, and the origins of morality. Jonathan Wells, author of The Politically Incorrect Guide to Darwinism and Intelligent Design, disagrees with Shermer.
