A fictional classroom's response to Intelligent Design

An excerpt:

"Ms. Cleary assigns this argument a grade of F for "forget it." As physicist Mark Perakh of California State University, Fullerton has pointed out, if the loss of a single part destroys a system's function, then that system has been poorly designed. Any well-designed system contains features that not only perform their regular roles but can compensate for losses or malfunctions elsewhere. Indeed, scientists are finding that biological systems exhibit just this kind of resiliency and complexity. Biology is messier and more adaptive than IDologues imagine."
