Well, this is one species concept out of some say 25, some say 40. While
quite easily applicable, it would turn all current subspecies, and sometimes
even smaller taxa, into species. Every breed of domestic animal or plant,
for example <shudder>.

So subjective that some even want to abolish species altogether, in favor of
naming just clades -- smaller and smaller clades.
