Phylogeny of Modern Birds

Palaeognathae

The Palaeognathae received their name from the ancient Greek word for "old jaws", paleognath, in reference to the skeletal anatomy of the palate. Traditionally there is a split between the ratites, who are flightless, and the tinamous, ground dwelling birds from South America and Mexico. But the last group of birds can fly. Recent analyses showed that the ratites are polyphyletic. 

The Palaeognathae contain eight groups, six extant and two extinct. The relationships between the groups are still under debate. But it seems that the Strutionidae are most primitive. The Casuaridae, the Dromaiidae and the Apterygidae form a clade. The position of the other clades, Aepyornithidae, Rheidae, Tinamiformes and Dinornithidae, remains uncertain.
