Animalia (Animals)

The various recognised taxonomic groups have changed radically since Carl Linnaeus enumerated them in 1758 (Systema Naturae, tenth edition). With the creation of seemingly ever more trivial taxonomic ranks (e.g. McKenna & Bell, 1997) and the surgence of cladistics in the late 20th century, higher taxonomy has become both über dynamic and über complex. The situation is increasingly being recognised as artificial, since Linnaeus' taxonomic system is essentially predicated upon false bifurcations. While speciation (the evolution of new species) certainly entails genetic divergence, at the biological level it is far more subtle than incorrigible divisions. Populations often freely hybridise and introgress long after they have "diverged". In reality life is like a long, winding, labrinthyne river. It's salinity level may differ here and there, but such changes are just as natural as the clear continuity of one droplet with the next as they move together through genetic space and time. The odd one being liquidated through evaporation (i.e. extinction).

 

Taxonomic ranks encompassed by square brackets (i.e. "[]") have no relevant subordinate taxa. That is, none of the species or subspecies included therein both a) survived at least until the Late Pleistocene and b) are missing, extinct or rediscovered.
