The fins of a shark and a dolphin are favourable adaptations for animals that need to swim and move in the water. But sharks are classified within the fish family while dolphins are mammals. WebAn example of homologous characters is the four limbs of tetrapods. Birds, bats, mice, and crocodiles all have four limbs. Sharks and bony fish do not. The ancestor of tetrapods evolved four limbs, and its descendents have inherited that feature — so the presence of four limbs is a homology.
