I've been talking with a few other taxonomists as well as reading some recent publications to find that classifying subspecies is archaic. It seems they have found that with every subspecies that they all fit into one clade or another despite looking differently. Subspeciation was simply a way to identify different physical appearances before the age of DNA and is what we now know to be simply different geographical morphs. So simply speaking integrade is nonexistent because if two "subspecies" produce viable offspring it is within the same clade and is the exact same species despite phenotypical differentiation.
Am I on the right track and what do you think of this tidbit?
