Biological symmetry

edited April 2014 in General

I was having a discussion (argument) with a creationist about evolution and he brought up a point that I have never heard discussed before.

He said that if evolution were true we would have two right hands and feet, or two left hands and feet. He claimed that a natural process is not intelligent enough to transpose one gene into a left and a right anything.

I had to just say I don't know how this works, but saying that "God did it" does nothing to explain it. (He thought he had won that round.) I tried to Google this but found nothing, so I am wondering if anyone out there can explain how biological systems work, for example is there just one blueprint for making a finger, and that is somehow repeated 20 times to form left and right toes and fingers?
