LOOKING AT THE EYE
The human eye is perhaps the best-known example of a complex system that couldn’t just pop up overnight. (“Say, Bill, what’s that thing growing on your face?” “I thought it was acne, but now that you mention it, I think I can see out of it.”)
With the eye we are not merely dealing with complexity, but with hundreds of separate parts that must work together in unison with incredible precision.
Those who study the inner workings of the eye say it operates much like a television camera, but is far more sophisticated. In fact it is more sophisticated than any machine imaginable.
