WebbAccording to the phylogenetic tree, whales and their relatives (cetaceans) are closely related to a group that contains the cow and deer (artiodactyls), but only whales have a long torpedo-shaped body. Therefore it is concluded that that trait appeared on the branch after whales and artiodactyls diverged from their common ancestor.
