1. The process by which new distinct species evolve.

   “In both groups, however, we find copious and intricate speciation so that, often, species limits are narrow and ill defined.”

   “No one had ever seen a new species produced, nor, according to Darwin, should they expect to. Speciation was so drawn out as to be, for all intents and purposes unobservable.”

2. The formation of different (inorganic) species (especially of ions) as the environment changes.
3. The determination of which species are present in a fluid or tissue specimen, bacterial culture, or viral culture.
