Check out the article entitled "Brave New Schools. Darwin-only challenger libel. Parent says 'evolution spokeswoman' trying to discredit effort" at

The following is an interesting excerpt:
"Scott--executive director of the Oakland, Calif.-based National Center for Science Education-wrote that Caldwell attemped to get the district to adopt materials advocating Biblical creationism, including a young-earth creationist book, 'Refuting Evolution,' by Jonathan Safarti, and the Jehovah's Witness book "Life: How Did It Get Here? By Evolution or Creation?'
"But Caldwell told World Net Daily he has never even heard of those books."
Although it doesn't name his religious persuasion, it doesn't appear to be Jehovah's Witnesses.
