If there are only two of each animal, then that means all of their offspring will be siblings. And two individuals alone can't repopulate an entire planet, and even if they could they would eventually die -- so at some point all consecutive animals would be inbred.

So it doesn't actually work...

I mean, I guess if you inbreed long enough you'll go through a lot of trial and error with who gets the bad genes and whatnot, and the flaws will eventually be worked out at least somewhat -- but still.
