Human-type intelligence makes artificial selection possible. not to put the cart before the horse.
So poor at reasoning, aren't you Paul?
If artificial selection is not possible except by humans, then it's only conducted by humans, then you're really admitting there's no separation between 'human selection' and 'artificial selection'.
As explained to you, the sole distinction between artificial and natural selection is 'intent' - selective breeding. That type of intent is, to our knowledge, restricted to humans. That's why the concept of 'artificial selection' continues to have some worth as a currency of discussion, but anyone familiar with the actual mechanical processes is well aware that there is no physical distinction at all.
You, of course, are not aware of this. Any of this, in fact. Near perfect ignorance apparently provides near perfect confidence.
