What is your definition of "species"?

That's the question that the authors need to answer. As it stands now they say balcks and whites are different species. See my point? sloppy work or sloppy writing. Something needs to be fixed

As it stands now they say balcks and whites are different species. See my point? . As the authors do not say that, I don't see your point. Even had the authors stated such, you haven't posted why you would object.

Again, (giving you one more chance to be evasive), what is your definition of "species"?
