True enough. What I said was that interbreeding is a criterion used for species and genus classification.
There is no agreement among experts whether the domestic dog is Canis familiaris or C. lupus familiaris, or whether red wolves are simply hybrids of coytes and gray wolves. Variety-subspecies-species is a fairly arbitrary distinction. And don't forget the chihuahua and great Dane, which have to be considered different species because they can't mate.
No agreement on what species dogs are, huh?
So that lets you claim that the Chihuahua is a separate species without having to name it?
Same w/ the Great Dane?
What does the 'scientific' definition of species actually mean?
Nothing?
