Thus are new species created. The name of a species, according to Ghiselin and Hull, is a proper noun, the name of a single and unique individual that has a beginning, a history, and an extinction, and which also has a distribution in space. Homo sapiens is not, on this view, the name of a 'type' of rational animal as Aristotle had it, but the name of a particular lineage of hominoids that happened to develop language and ratiocination. If all humans were extinguished next year, they could never arise again. This deserves an essay on its own, but not by me.
Species are biological entities that change.
