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.
