WebBird phylogeny has been somewhat controversial, perhaps reflecting a rapid divergence early in their evolutionary history. There are two superorders, the Paleognathae or ratites, and the Neognathae. The earliest divergences within modern birds, between Palaeognathae and Neognathae, are estimated to have occurred in the mid-Cretaceous. WebANGRY BIRD EVOLUTION so Lazy monster GAMEPLAY This.

WebThe evolution of birds began in the Jurassic Period, with the earliest birds derived from a clade of theropod dinosaurs named Paraves. Birds are categorized as a biological class, Aves. For more than a century, the small theropod dinosaur Archaeopteryx lithographica from the Late Jurassic period was considered to have been the earliest bird.

The phylogenetic classification of birds is a contentious issue. Sibley & Ahlquist's Phylogeny and Classification of Birds (1990) is a landmark work on the classification of birds (although frequently debated and constantly revised). A preponderance of evidence suggests that most modern bird orders constitute good clades. However, scientists are not in agreement as to the precise relationships between the main clades.
