"You could argue that these are not really different species, but they are usually classified as such."
you could argue, but i not, me. reproductive compatability means wild type organisms not artificially coerced.
there are tiers of incompatability, biochemical, physiological, anatomical, behavioral, geophysical, geographical.
incompatability on any of those levels, drives speciation.
once again speciation is not about artificial [anthropogenic] induction of reproductive function, it is about wild type incompatability.
no you cant argue. but your forgiven for not having the knowledge, and being fed half knowledge out of brevity.
evolution is real, speciation is real, saying let it be so, and it will manifest itself, is not real.
oh by the way, we are a species of primate, not dust, and rib bones.
