Progenitor–derivative speciation in Pozoa
Progenitor–derivative speciation in Pozoa

Progenitor–derivative speciation occurs when an isolated peripheral population diverges from the ancestral condition and forms a derivative species. López et al. find evidence of this type of speciation in the genus Pozoa (Apiaceae), consisting of two species endemic to the southern Andes. Pozoa volcanica appears to have derived recently from the progenitor, P. coriacea, as evidenced by the former’s reduced genetic variability (determined using AFLP analysis), narrow geographic distribution and restricted range of ecological tolerance.
