It probably occurred some 120 million long time ago in the form of a common ancestor, today extinct, that bore scant resemblance to either modern worldly concern or modern dolphin (Knudtson, pg. 22).         Reflecting this evolutionary history, modern killer whales continue to anatomically mirror those distant times. Although we think of killer whales as sleek and hairless, for example, kindred other cetaceans, they do posses hair, the trademark of the class Mammalia, if fleetingly during fetal stages of development (Knudtson, pg. 23). The killer whales fetus, also transiently displays such other mammalian traits as four victimize limbs, a pelvis and a tail.         In addition, the huge skeletons of killer whale adults, so hydro dynamically sculpted for aquatic life, are, like our own, simply variations on a fundamental mammalian mold (Knudtson, pg. 23).
