In case anyone hasn't been following this issue, the theory of evolution is the basic framework of modern biology--it's the theory that life on has evolved and differentiated over many millions of years from common ancestors. Intelligent Design, by contrast, is a crackpot theory supported by a small handful of scientists (generally working outside their fields), which basically recapitulates the original argument from incredulity of the ninteenth century. It does so as follows:
(1) It defines the concept of "irreducible complexity"--a structure that could not have evolved (usually the argument is that the structure has no purpose if any piece were altered, and so could not have evolved).
(2) It points to specific structures and claims, without proof, that those structures are irreducibly complex, and so could not have evolved.
(3) It argues that therefore the structure must have been created by an intelligent designer (carefully left unspecified to avoid the obvious argument that this is simply religious creationism).
The problematic step, of course, is (2). Whenever any specific strucutre is shown (as has happened repeatedly since Intelligent Design was first formulated) to have a perfectly reasonable evolutionary path from simpler structures, the old infinite regression game begins: "Aha! But those pieces are irreducibly complex!"
The fact that the President of the United States is advocating abandoning our leadership in biology at this time (and that is exactly what he is proposing--intelligent design is useless as a scientific tool, doesn't itself meet the standard of a scientific theory, and has led to no results to date, despite years of work) is a disaster. Technological leadership is a cornerstone of our superpower status, which Mr. Bush seems bound and determined to destroy.
