You demand an answer to a question that is irrelevant to the theory of evolution, so I give you an irrelevant answer.
Evolution began the exact moment that the flying spaghetti monster says it began. I was not around when this happened, but if you give me a time machine necessary I’ll go make observations about it all and report straight to you.
Until then, you will get no speculation from me for you to kick around....so go kick the spaghetti monster a bit.
