Novaeratitae is a clade that was originally defined to contain the recent common ancestors of the orders Casuariiformes (emus and cassowaries) and Apterygiformes (kiwis).[1][2] Recently it has been determined that the elephant birds of the extinct order Aepyornithiformes were the closest relatives of the kiwis, and therefore are part of this group.[3] The implication is that ratites had lost flight independently in each group, as the elephant birds are the only novaeratites found outside Oceania.[3]
