The eye is a fascinatingly complex piece of machinery. So complex, in fact, that when looking at a diagram, a person can’t help but get the feeling it might have been designed for a purpose; much like the camera it mimics.

Why, then, do we have a blind spot near the center of our vision? Biology points to an optic nerve, carrying the newly gathered information back to the brain to be processed.

The theory of intelligent design ( “your father’s creationism” ) begs to differ. I’m hoping somebody who finds this blog might be able to suggest an answer? A human engineer would be fired for this type of design flaw in a camera; surely the all-knowing could be expected to hold down a job at Nikon, if he so chose.

Natural selection would favor a good, but imperfect, eye if it gave its owner an advantage at survival and procreation. The genes for making a flawed eye would quickly spread through a pool for not making any sort of eye. The information being gathered by our rods and cones has to make it back to the brain somehow. If a small blind-spot is the price for sight, this puts creatures with an eye at an advantage.

But God is all-powerful and all-knowing, unencumbered by simple physics. In creating the universe, God must have created the laws of the universe, to his satisfaction. He could easily have designed us with no blind spot. Or, of course, with a better resistance to disease, without such a foul temperament, or any number of ways more befitting the image of our creator.

How does the theory of intelligent design explain these and other design flaws?
