I was wondering how the orcs multiply? realizing of course that there's no "mommy orc" and "Daddy orc" and things go on as normal but that somehow they do come out of the ground, at least the urukai do; That is if the movie was correct (which i'm not saying it is.) I of course don't mean to be vulgar or inappropriate here but it is just a biological question.
I realize that the orcs were simply elves that were captured and twisted by Melkor and then while the elves that still remained multiplied and lived so did the race of the orcs. My only question is how?
I know that the orcs of Isenguard were science experiments so they would come out of the ground like falling out of a test tube so i really have no idea.
