So you're saying that speciation does not occur? Do I have you correct here?
Varietes or subspecies may represent species in the making. Ever here of
incipience? This got Goldschmidt's dander up if I recall him aright.
You have a series of subspecies along a continuum. Each subspecies can
interbreed with the other except for those at the extremes of the continuum.
If the intermediates were wiped out the extreme subspecies *could* be
considered full-fledged species.
