No, the nerve (recurrent laryngeal nerve) is far from useless, and all mammals have it.
"The recurrent laryngeal nerve (RLN) is a branch of the vagus nerve (tenth cranial nerve) that supplies motor function and sensation to the larynx (voice box)."
"Other than the cricothyroid muscle which is innervated by the superior laryngeal nerve, motor control of all the intrinsic muscles of the larynx, the thyroarytenoid, the posterior and lateral cricoarytenoid, and arytenoid muscles depends upon the recurrent laryngeal nerve. Additionally, it transmits sensory information from the mucous membranes of the larynx from the lower surface of the vocal fold, downwards."
Skepticism is not a position; it is an approach to claims.
