One common form of this process is often driven by failed meiosis and self-fertilization.
One common form of this process is often driven by failed meiosis and self-fertilization. Gould theorized that it principally takes place in sudden spurts in his theory of punctuated equilibrium. It is reinforced by the Wallace effect, which allows the sympatric form to proceed, while geographic isolation results in the allopatric form. For 10 points, identify this process through which a population of organisms becomes unable to interbreed, having formed separate taxa at a level one lower than genus.
