The monodontids, [[oceanic dolphin]]s (Delphinidae) and [[porpoise]]s (Phocoenidae) together comprise the [[Delphinoidea]] superfamily. Genetic evidence suggests the porpoises are more closely related to the white whales, and these two families constitute a separate [[clade]] which diverged from the DelphinoideaDelphinidae within the past 11 million years.<ref>{{cite journal | author = Waddell, V.G. | author2 = Milinkovitch, M.C. | author3 = Bérubé, M. | author4 = Stanhope, M.J. | last-author-amp = yes | year = 2000 | title = 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) | journal = Molecular Phylogenetics and Evolution | volume = 15 | issue = 2 | pages = 314–318 | doi = 10.1006/mpev.1999.0751 | pmid=10837160}}</ref>
