Index Sister group

A sister group or sister taxon is a phylogenetic term denoting the closest relatives of another given unit in an evolutionary tree. [1]

Bird

Birds, also known as Aves, are a group of endothermic vertebrates, characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton.

Cladistics

Cladistics (from Greek κλάδος, cládos, i.e., "branch") is an approach to biological classification in which organisms are categorized in groups ("clades") based on the most recent common ancestor.

Cladogram

A cladogram (from Greek clados "branch" and gramma "character") is a diagram used in cladistics to show relations among organisms.

Crocodilia

Crocodilia (or Crocodylia) is an order of mostly large, predatory, semiaquatic archosaurian reptiles, known as crocodilians.

Most recent common ancestor

In biology and genealogy, the most recent common ancestor (MRCA, also last common ancestor (LCA), or concestor) of any set of organisms is the most recent individual from which all the organisms are directly descended.

Neontology

Neontology is a part of biology that, in contrast to paleontology, deals with living (or, more generally, recent) organisms.

Phylogenetic tree

A phylogenetic tree or evolutionary tree is a branching diagram or "tree" showing the evolutionary relationships among various biological species or other entities—their phylogeny—based upon similarities and differences in their physical or genetic characteristics.

Phylogenetics

In biology, phylogenetics (Greek: φυλή, φῦλον – phylé, phylon.

Species

In biology, a species is the basic unit of classification and a taxonomic rank, as well as a unit of biodiversity, but it has proven difficult to find a satisfactory definition.

Taxon

In biology, a taxon (plural taxa; back-formation from taxonomy) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit.
