What is the most primitive bird alive today?
Based on genetics and on the fossil record, there’s general agreement that the most primitive groups of birds today are several families of flightless ground-dwellers—ostriches, emus, cassowaries, rheas, kiwis—plus the tinamous, which can fly, but not very well.

|---|---|
| -They usually adapt to terrestrial habitat. | -They adapt in all the spheres. |

Are penguins Paleognaths?
Most of the birds classified in the Palaeognathae are also flightless, but not all flightless birds are classified in the Palaeognathae. Some flightless birds, such as living penguins, puffins, and rails, and the extinct auks and phororhacoids, are classified in the Neognathae along with most flying birds.

Can Neognathae fly?
Neognaths (Neognathae) are birds within the subclass Neornithes of the class Aves. The Neognathae include virtually all living birds; their sister taxon Paleognathae contains the tinamous – their only order capable of flight – as well as the flightless ratites.
Which two orders of birds are known commonly as fowl?
The birds referred to as fowl belong to one of two orders: the gamefowl or landfowl (Galliformes) and the waterfowl (Anseriformes). Studies of anatomical and molecular similarities suggest that these two groups are closely related.
What can Paleognaths fly?
Ultimately, the earliest recorded paleognaths are flying, presumably plesiomorphic lithornithids, found quite possibly as early as the Late Cretaceous in North America, while some of the earliest flightless ratites occur in Europe.
Are penguins neognathae?
All other living birds, from hawks to hummingbirds and from plovers to penguins, are classified in the Neognathae.

The casuariiform skeleton is similar to that of the other large flightless birds (ratites) in the reduction of the wing elements and of the keel on the sternum (breastbone) and in the enlargement of the leg elements.
What is the difference between Casuariidae and Dromaiidae?
The family Dromaiidae, made up of the single living species of emu (Dromaius novaehollandiae), is found only in Australia, whereas the family Casuariidae, made up of three species of cassowaries (Casuarius), is restricted to northern Australia, New Guinea, and nearby islands.
