You are studying the skeleton and bone morphology across reptiles. You find that in alligators a certain bone in the jaw has elongated whereas in a species of chameleon the bone has shortened in the jaw. In both species the bone still helps control feeding. Is this bone and skeletal morphology a homology?   a. Yes, it is a homology   b. No, it is not a homology   c. Not enough information to tell   d. The answer depends on the specific diet of each species

Mastodon fossils were found in the same area where modern-day elephants live. O C. Mastodons walked on four legs like modern-day elephants.
