take aristotle's attempt at taxonomy, or biology for that matter. he thought that an animal species belongs to the same kind as those other species in similar habitat. in that case, whales and dolphins would be considered fish. and many people did believe whales and dolphins to be fish for many centuries after that, including those who never heard of aristotle, out of common sense.
