The recurrent laryngeal nerve, which is a branch off the Vagus nerve at the base of the brain, travels down the neck, around the arteries of the heart and then travels back up the neck to ennervate the larynx, or voice box. Evolutionist say, "why would an intelligent designer, create a loop such as this that seems illogical?" "Why not go directly from the brain to the larynx?" They then argue that since fish also have this nerve, that over time as fish developed into man, that this nerve (that also innervates gills) remained trapped under the arteries of the heart and got stretched as the mammalian necks got longer. The primary example they like to use is the giraffe neck. Picture from Wikipedia Picture from off internet

If one can prove there is purpose with it going down into chest, then it removes the "illogical" comment, and instead of "faulty" it becomes functional.
The well-known textbook Gray’s Anatomy states: “As the recurrent nerve hooks around the subclavian artery or aorta, it gives off several cardiac filaments to the deep part of the cardiac plexus. As it ascends in the neck it gives off branches, more numerous on the left than on the right side, to the mucous membrane and muscular coat of the esophagus; branches to the mucous membrane and muscular fibers of the trachea; and some pharyngeal filaments to the Constrictor pharyngis inferior.”
Dawkins (and other evolutionists) considers only its main destination, the larynx. In reality, the nerve also has a role in supplying parts of the heart, windpipe muscles and mucous membranes, and the esophagus, which could explain its route.
