Darwin's tubercle is a small cartilaginous protuberance, most commonly located along the concave edge of the posterosuperior helix. This tubercle is considered an atavistic remnant, and it is more commonly found in anthropoid apes, where it forms the apex of the helix. Because it suggests our common ancestry, it has been termed "Darwin's tubercle." Most commonly, Darwin's tubercle projects anteriorly from the concave edge of the posterosuperior helix. |
