VESTIGIAL BONES. “Examples include cranial and other bony sutures that reveal formerly distinct ossification centers. During formation of endochondral (cartilage replacement) long bones, a growth zone forms between the bony shaft (diaphysis) and end plate (epiphysis). These elements eventually fuse when growth ends, leaving a tell-tale epiphyseal line where elements were formerly separated. This too is an artifact of ontogeny.”
