Anagenesis+vs.+Cladogenesis

Anagenesis vs. Cladogenesis Anagenesis and cladogenesis are two patterns of evolutionary change.


 * Anagenesis** (//ana//, new, and //genos//, race) is the collective changes that transform one species into a different species with different characteristics. Anagenesis is also called phyletic evolution.


 * Cladogenesis** (//klados//, branch) is the speration of a gene pool into two or more gene pools. Said pools then eventually produce one or more new species. Branching evolution is another name for cladogenesis. Cladogenesis is the only evolutionary change that can "promote biological diversity by increasing the number of species (1)."
