It probably occurred some 120 million long time ago in the form of a common ancestor, direct extinct, that bore scant resemblance to either modern gentleman or modern dolphin (Knudtson, pg. 22).         Reflecting this evolutionary history, modern grampus 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 earmark 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 slight limbs, a pelvis and a tail.         In addition, the huge skeletons of killer whale adults, so hydro dynamically sculpted for aquatic life, are, similar our own, simply variations on a fundamental mammalian make grow (Knudtson, pg. 23).
