Paraspecies

Paraspecies are expected from evolutionary theory (Crisp and Chandler, 1996), and are empirical realities in many terrestrial and aquatic taxa.^{[3][4][5][6][7][8][9][10][11][12]}

Examples[edit]

• A well-documented example of a living mammal species that gave rise to another living species is the evolution of the polar bear from the brown bear.^[13][14]

• An example of a living reptile paraspecies is New Zealand's North Island tuatara Sphenodon punctatus, which gave rise to the Brothers Island tuatara Sphenodon guntheri.^[15] An example of a living bird paraspecies is Empidonax occidentalis, the Cordilleran flycatcher.^[16][17]

• An example of a living plant paraspecies is Pouteria cuspidata, the pouteria trees or eggfruits.^[18]

See also[edit]

• Cladogenesis
• Anagenesis, also known as "phyletic change", where no branching event occurred (or is known to have occurred)
