Neognathae is now universally accepted to subdivide into two lineages, the "fowl" clade Galloanseres and the Neoaves (sometimes called "higher neognaths"). The formal PhyloCode definition given to Neognathae by George Sangster and colleagues in 2022 is "the least inclusive crown clade containing Gallus gallus and Passer domesticus ".
Neoaves is a clade that consists of all modern birds (Neornithes or Aves) with the exception of Palaeognathae (ratites and kin) and Galloanserae (ducks, chickens and kin). [4] ...

Recent genetic data show that ground hornbills and Bycanistes form a clade outside the rest of the hornbill lineage. [6] They are thought to represent an early African lineage, while the rest of Bucerotiformes evolved in Asia.
Passerea is a clade of neoavian birds that was proposed by Jarvis et al. (2014). [3] Their genomic analysis recovered two major clades within Neoaves, Passerea and Columbea, and concluded that both clades appear to have many ecologically driven convergent traits.
Galliformes / ˌ ɡ æ l ɪ ˈ f ɔːr m iː z / is an order of heavy-bodied ground-feeding birds that includes turkeys, chickens, quail, and other landfowl.Gallinaceous birds, as they are called, are important in their ecosystems as seed dispersers and predators, and are often reared by humans for their meat and eggs, or hunted as game birds.

It is estimated that more than 99% of all species that ever existed on Earth, amounting to over five billion species, [3] are extinct.
