The recurrent laryngeal nerve as evidence for evolution

Why the recurrent laryngeal nerve is evidence for evolution…

But isn’t it the case that if there were a functional reason that it too would be explained by evolutionary theory? Take the “wiring” of the vertebrate eye (not to change the subject). Has that argument been dropped in favor of this one now?

Correct. The argument only works in one direction, but fortunately this is the direction in which it has been used. The recurrent laryngeal nerve is an argument against design, or at least against design that doesn’t make use of common descent. If the larynx were innervated in a more sensible way, it wouldn’t be an argument against anything.

Since you don’t want to change the subject, I won’t mention the vertebrate eye.
