The process of evolutionary branching of basic forms into specialized forms by differentiation, specialization and adaptation.

The formation of independently evolving lineages from a single ancestral line through speciation.

The development of a new clade; the splitting of a single lineage into two distinct lineages; speciation.

(see speciation)

A form of evolution that occurs by species diverging into two species, with the original species and the new species both persisting. This form is referred to as branching evolution because the new species has branched off from the original species.

evolutionary change that results in the splitting of a lineage and a new branch or clade of the phylogenetic tree

the formation of lineages (phylogenies) through progressive peciation, diversification, and xtinction. The vertical axis is time and the horizontal axis is the range of a trait.

The evolutionary splitting of lineages, i.e. speciation (cf. phylesis).

the origin of a branch on a phylogenetic tree; the pattern of cladogenesis results from the process of speciation.

The splitting of a species lineage into two species lineages.

The evolution of two or more daughter species from a single parent species by the splitting of a lineage.

Cladogenesis is an evolutionary splitting event in which each branch and its smaller branches forms a "clade", an evolutionary mechanism and a process of adaptive evolution that leads to the development of a greater variety of sister organisms.
