Molecular phylogenetic examination of the Delphinoidea trichotomy: Congruent evidence from three nuclear loci indicates that porpoises (Phocoenidae) share a more recent common ancestry with white whales (Monodontidae) than they do with true dolphins (Delphinidae)
Porpoises (Phocoenidae), dolphins (Delphinidae), and the two species of Monodontidae (beluga and narwhal) together constitute the superfamily Delphinoidea. Although there is extensive evidence supporting the monophyly of this superfamily, previous studies involving morphology, as well as sequence an...
