What's most notable about this paper is the similarity in design reasoning between the authors and the more familiar advocates of intelligent design theory. No appeals to religion or religious texts; no identifying the designer
Whatever gives you the idea that it would be "the" designer, singular? Most design projects are the products of teams. As an ID advocate, would you agree to the teaching of Intelligent Design "theory" on the condition that the claimed intelligent agency must be referred to as "the designers," plural?
