I like to call this nonsense. Do you honestly think that a "perfect"
organism never undergoes mutations that may become fixed and lead to a new
speciation event? Hah, that would be the day.

I agree with the latter qualification. But I think the entire concept of
"perfect organism" is total nonsense. It's a very typical human-centered
deterministic attitude. I'd say that it goes back to the Middle Ages.
