In plants, this process often occurs due to changes in (*) ploidy.
A necessary condition for this process to occur is described in the BatesonÂ–DobzhanskyÂ–Muller model. Richard Goldschmidt described how this process can occur in a "saltatory" fashion via the creation of a "hopeful monster." This process can occur due to vicariance or jump dispersal events. In plants, this process often occurs due to changes in (*) ploidy. This process occurs in bursts according to the theory of punctuated equilibrium. Absence of gene flow and geographical isolation are the primary causes of the "sympatric" and "allopatric" types of this process. For 10 points, name this evolutionary process in which two reproductively isolated populations diverge taxonomically.
