Another thing to point out with these threads is the tossing around of the word "unnatural," which, as I perceive it, has zero inherent weight and is merely an arbitrary exclusion of human affairs from nature for zero rational causes. Exactly why is an ant colony creating an ant hill any more natural than a human village or city? Everything is "natural" in the sense that all occurrences are governed by natural laws and reasons, including whatever the hell humans decide to do in their laboratories. Clones would be no less natural than children born through sexual reproduction.
