Uberon definition : The incus or anvil is the anvil-shaped small bone or ossicle in the middle ear. It
connects the malleus to the stapes. It was first described by Alessandro Achillin
of Bologna. The incus transmits sound vibrations from the malleus to the stapes. The
incus only exists in mammals, and is derived from a reptilian upper jaw bone, the
quadrate bone. Embryologically it is derived from the first pharyngeal arch along
with the rest of the bones of mastication, such as the maxilla and mandible. [WP,unvetted].;

Uberon broad term : quadrate - incus;
Uberon Homology note : According to this theory (Reichert-Gaupp theory), the mammalian stapes is derived
