Riddle me this, you have 2 populations containing 2 sub-populations each. Lets call them populations Aa and Bb. 'a' can mate with 'b' and produce c. c can produce viable offspring with A or B but A and B can not produce viable offspring. What do we call Aa and Bb if not distinct species? What do we call c? What if some members A can produce viable offspring with B some of the time but not always? What then? My point is we make taxonomical distinctions for our convenience, they don't really have any hold on the natural world.
