There is no such argument within the scientific community. In response to the PUBLIC controversy, many scientific societies have issued position statements on Intelligent Design Creationism. For example,
The American Association for the Advancement of Science is the world's largest general scientific society. The AAAS serves some 262 affiliated societies and academies of science, serving 10 million individuals.
* A 2002 statement states: "[T]he lack of scientific warrant for so-called 'intelligent design theory' makes it improper to include as a part of science education."
* A 2006 statement on the teaching of evolution: "Some bills seek to discredit evolution by emphasizing so-called "flaws" in the theory of evolution or "disagreements" within the scientific community. Others insist that teachers have absolute freedom within their classrooms and cannot be disciplined for teaching non-scientific “alternatives” to evolution. A number of bills require that students be taught to "critically analyze" evolution or to understand "the controversy." But there is no significant controversy within the scientific community about the validity of the theory of evolution. The current controversy surrounding the teaching of evolution is not a scientific one."
Oh, and by the way, evolution by natural selection HAS been proven. That is why it is referred to as a "theory" (you know, like the atomic theory for example--if you don't think the atomic theory has been proved then you be the one who holds the dynamite when it's lit, not me)
I am a scientist with a Ph.D. in zoology.
