Cladogenesis
|
|
Cladogenesis is an evolutionary splitting event in which each branch and its smaller branches is a "clade"; an evolutionary mechanism and a process of adaptive evolution that leads to the development of a greater variety of animals or plants.
Cladogenesis is often contrasted with the process entitled "Anagenesis", where gradual changes lead to the development of a new species with the replacement of the old species (i.e: there is no "Splitting" of the Phylogenetic tree.).
