Do you realize how that came out sounding? It sounds like you're implying that evolution is very illogical, that it makes no sense.

With respect, I believe that you have misunderstood the thrust of his statement, which I do not believe to be unclear. His claim is that it would be illogical to design a nerve that runs in such a way, however it is not illogical to conclude such a structure to come about through undesigned evolution. His point is not that evolution is "illogical", but that, because there is no intervening agent constructing the organisms, it can lead to structures within an organism that are not as efficient as they would be were they assembled by an intelligent designer.

His point is not that evolution is "illogical"...

...but that it shows a lack of planning.

IF the nerve had been designed (at least by any engineer I can imagine), it would resemble the one on the right side.

The circuitous route it takes is an example of the fact that evolution always is constrained by what's already present.
