When i took advanced anatomy in high school a while back, my teacher said that every human has thousands of mutations within their own genetics that are truly unique to that person. The thing is we are so accustomed to people looking different or the same as each other that we dont see it as a mutation, just how that person looks (hair, eyes, height, skin color). This can be transferred to the world of ball pythons where im sure every snake as multiple unique muations, its only the rare 1 in a million that has a mutation that stands out to the eye. Just imagine how many morphs are hidden behind a normal looking paint job, but may contain a super form . Theyre just to far spread apart in the world that they do get to breed with each other.

Many times its just dumb luck where someone breeds two normals with 2 different hidden mutations that combine to show something fancy.

The cool thing is that i believe the number of morphs will always be unlimited because every new baby will have new mutations that could be possibly mixed with other mutations through breeding to create new morphs

More babies= more mutation crosses=more eventual morphs!

Evolution!
