That's quite an assumption. I think there were 42 original proto-organisms spread over all the aeons. Creating a 43rd artificially is not a big deal.

Definitely. If I'm mistaken and we can point to an organism living right now which isn't directly related to / descendant from the Last Universal Common Ancestor then we're already dealing with multiple "individuals", and having another indeed would be no big deal.

Otherwise, I still think that it would be.

To clarify, though: I'm not at all against the creation of another individual.
