Stick to Keeping the Mexicans Out of America

This sums up Pat Buchanan's ignorance in a nutshell.
And when you consider the clocklike precision of the planets in their orbits about the sun and the extraordinary complexity of the human eye, does that seem to you like the result of random selection or the product of intelligent design?,

This pile of shit was debunked in my first page of my (the horrors) human evolution textbook with an argument similar to this.
ery change had to confer a survival advantage, no matter how slight. Eventually, the light-sensitive spot evolved into a retina, the layer of cells and pigment at the back of the human eye. Over time a lens formed at the front of the eye. It could have arisen as a double-layered transparent tissue containing increasing amounts of liquid that gave it the convex curvature of the human eye.

In fact, eyes corresponding to every stage in this sequence have been found in existing living species. The existence of this range of less complex light-sensitive structures supports scientists' hypotheses about how complex eyes like ours could evolve. The first animals with anything resembling an eye lived about 550 million years ago. And, according to one scientist's calculations, only 364,000 years would have been needed for a camera-like eye to evolve from a light-sensitive patch.
