It needs to be pointed out that conception and cloning is a biological/scientific concept, and bestowing of souls is a spiritual concept.
If such is the case that animals are without souls, then conception can and does happen without a soul involved, and statements such as the following should not be made as they confuse the concepts ~ inferring that one is dependent upon the other.
A test tube baby has a spirit because the egg and sperm meet.
It appears as though there is a criteria (egg + sperm) in order for a soul to become, as well as a definitive: egg + sperm = soul. You have already agreed, it appears, that you are going off the premise that that is not the case ("animals do not have souls", yet they have conception). Either one is so,
or the other by your own logic.
I don't know if that makes sense any place other than in my head. Any more than that, and it is only my opinion, which would constitute a gathering of angry villagers with pitchforks and torches. I am only posting to point out what I see as a contradiction in the theories presented.
