Cetacean phylogeny and systematics based on the morphogenesis of the nasal skull. Aquatic Mammals 21(2): 79-89. (Zentrum der Morphologie, Klinikum der J.W. Goethe-Universitat, Theodor-Stern-Kai 7, D-60590 Frankfurt, FRG) The morphogenesis of the nasal skull of the cetaceans indicates that the traditional division of the order Cetacea into two suborders, the toothed whales (Odontoceti) and the baleen whales (Mysteiceti), is phylogenetically not substantiated. The following conclusions can be drawn on the basis of the presented study. The whales are of a monophyletic origin, with all the extant forms being closely related. The sperm whales are, however, distinct from other odontocetes, with which they are traditionally associated, and seem to be more closely related to the baleen whales. The embryological findings presented here are remarkably consistent with a recent molecular phylogenetic analysis. According the morphogenesis of the naskal skull the following almost equivalent groupings, which may be considered superfamilies, can be distinguished within the order Cetacea: Balaenopteroidea, Physeteroidea, and Delphinoidea. However, no representatives of the families Ziphiidae and Platanistidae were available for the present study.
