Jaws appear to have evolved from
◦ modification of a disk of bones surrounding the mouth in lampreys.
◦ the fusion of many bony elements found in the skin of the neck region of jawless ancestors.
◦ a large, bony shield that protruded from between the base of the pectoral fins.
◦ skeletal rods that supported gill slits near the mouth.
