Darwinian theory proposes a paradigm which consists of (natural) variation and (natural) selection.

So...to repeat a previous question, if ants enslave aphids and thereby alter their genomic destiny, is that (natural) selection or (unnatural) selection? How about if humans enslave dogs? How about if taurian lizard people enslave humans? How about if taurian lizard people engineer our ancestral seed directly with DNA-creating machines?

That's like asking if ant holes are natural or artificial. The word "artificial" is generally understood to mean, done by humans, or by lifeforms with at least a similar level of intelligence and sentience.
