Paraspecies

A paraspecies (a paraphyletic species) is a species, living or fossil, that gave rise to one or more daughter species without itself becoming extinct. The concept of a paraspecies emerges naturally from the Evolutionary Species Concept. Geographically widespread species that have given rise to one or more daughter species as peripheral isolates without themselves becoming extinct (i.e. through peripatric speciation) are examples of paraspecies. A well-known example is the evolution of modern humans Homo sapiens from the ancestral species Homo rhodesiensis.
