Well, don't mutations need a trigger? Things don't usually mutate for no reason as far as I know. There have to be conditions that facilitate, trigger or make mutation necessary. Thats why you don't just automatically get Mangekyou Sharingan from getting older. At least thats what I think. But I didn't major in biology or anything so I won't argue/debate this point with you too much lol. For all I know you could have a masters on the subject.
