(klay-doh-gen-eh-sis) [Gk. clados, branch + genesis, origin] A pattern of evolutionary change that produces biological diversity by budding one or more new species from a parent species that continues [..]

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

The division of an ancestral parental lineage into two or more daughter lineages or species. At one time, cladogenesis was recognised, along with anagenesis, as one of the two types of gradual evolution. Because the highly formalised trees that cladistics use on do not show anagenesis, a misplaced literalism led to cladogenesis, in the sense of the [..]

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

Branching or divergent evolution caused by speciation. Results in two or more branches on the phylogenetic tree where earlier only a single branch existed. A species resulting from cladogenesis has on [..]

The splitting of an ancestral species into daughter species that coexist in Time (King, Dictionary of Genetics, 6th ed). Causal factors may include geographic isolation, HABITAT geometry, migration, R [..]

Species formation, the branching of a single lineage to form two lineages.

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

The evolutionary process whereby one species splits into two or more species. See anagenesis.
