The Ratites are the most basal order of modern birds. They are an assemblage of secondarily flightless birds, which are united by a number of primitive characters, including a keel-less sternum, a reduced furcula, sturdy hindlegs and reduced wings. Examples of Ratites include cassowaries, emus, kiwis, ostriches and rheas.
