[QUOTE="Split Rock, post: 68169144, member: 17087"] There is no such thing as "de-evolved." You have either been watching too many Star Trek episodes, or reading too many comic books. Flippers are not fins. Whale flippers are homologous with our hands, not with ray fins, for example (like the majority of fish have). They are homologous with the fins of lobe-finned fish, however. This is why we believe all land vertebrates evolved from this type of fish. Nevertheless, they are not identical. No, no, no. :doh: Our hands evolved from lobe-finned fish that actually had the same bones in their fins as we have in our hand. Whales also have the same bones. A flipper is easy to make... its just a stretch of skin between bones. So, in this case fin----> hand-----> flipper, was the proper sequence. [/QUOTE]
