Third, the jaw musculature seems to be homologous to the original gill support musculature. Geologic Time Scale 3. Thus, the vertebrate jaw appears to be homologous to the gill arches of jawless fishes. Nauplius larvae of A a barnacle Tetraclita, seen in ventral view and B a shrimp Penaeus, seen in dorsal view. The shrimp and barnacle share a similar larval stage despite their radical divergence in later development.

    Thus, the middle ear bones of the mammal are homologous to the posterior lower jaw of the reptile and to the gill arches of agnathan fishes.

    Thus, the vertebrate jaw appears to be homologous to the gill arches of jawless fishes.
