While humans do not rely solely on vocalization for survival, the biological remnants of this evolutionary pressure remain evident in the structure of the male neck. In many animal species, deeper calls are associated with larger body size and dominance.
Secondary Sexual Characteristic Throat: The Biological Role of the Larynx
One hypothesis suggests that the enlargement of the larynx and the resulting deep vocal pitch served as a secondary sexual characteristic. This biological mechanism is the primary reason men generally have lower voices than women, making the prominence of the Adam's apple a visible marker of vocal physiology.
The Role of the Larynx in Voice Production The larynx houses the vocal cords, which are essential for producing sound. This growth is not uniform; the thyroid cartilage expands more rapidly than the surrounding tissues, creating the distinct angle and protrusion.

While both sexes are born with this structure, it is typically far more noticeable in males. This fusion creates the distinct protrusion that defines the Adam's apple.
