Regarding the dead animals, I have to remind you that, at least anatomically, we are at the top of the evolutionary pyramid. There are no good substitutes. Among two-legged types even the chimpanzee's head is hung like a japanese lantern on his neck - whereas the human ape stood up and the skull is more centerally located. GM has used pigs and rabbits for such things, but the chest cavity is quite different in a pig, for example.
