John Morris, president of the Institute for Creation Research in San Diego, California, says he and others at the institute are scientists who frame and study the question of human origins from a biblical perspective.
Morris said most creationists believe in "micro" evolution -- evolution with limitations. An example of microevolution is the variety of dog breeds -- proof that life forms can change genetically within certain parameters, he said.
Evolutionists regard "macro" evolution as gospel, he argued, meaning they believe complex life forms such as humans originated from the simplest of living things like fish.
"Dogs can change a lot, but they never become cats," he said. "Evolutionists point to this variation and say we can extend that philosophy from a fish to a man. ... In the sense that evolution teaches your ancestors were fish, I disagree with that. ... People were created as people. Evolutionists have sole control and the existence of those who don't agree is denied," he said.
He said though he believes evolution is "bad science," it must be taught in schools because students must be exposed to what much of the scientific community believes is true. He also said he does not want the Bible to be taught in schools, unlike some other Christian groups.
What he does want is for evolution to be taught as a theory, not fact. And he wants students to be exposed to the alternative point of view.
"The faith of evolution should not be taught. The faith of the evolutionists is that microevolution leads to macroevolution. That ought not to be taught," he said. "Creationism is good science. I would never propose putting the Bible in public schools, but to exclude good science is bad education."
