Because of its complexity, many creationists see the eye as a weak point in evolutionary theory. They make an argument of irreducible complexity: that if any single part of the eye was missing it wouldn't function. Therefore, eyes must have been created in their current form - by a creator! But as Dr. Ivan R. Schwab explains in his new book Evolution's Witness: How Eyes Evolved, this argument doesn't hold vitreous fluid. Much simpler eye designs not only existed in our evolutionary past, but in some animals alive today! We know how eyes evolved, and (spoilers!) no creator is needed.
