It can be environmental; ie: UV radiation (sunlight) can alter DNA as can chemical exposure and numerous other things and it can occur just due to freak chance. There is no solid answer for all of it because in most circumstances we have no idea what the variables are. You didn't see variation in your tests because they were too tightly controlled, no chance for external stimuli to introduce deviations and not enough generations for nature to have done it itself.
It's not having what you want - It's wanting what you've got.
