Both sides in the controversy would thus be vindicated: Ambulocetus, Pakicetus, and their more fully marine descendants in the extinct whale suborder Archaeoceti would in fact be descended from mesonychians, while the two extant whale suborders would share a common ancestor (probably more recently) with hippopotamoid artiodactyls.
