Saying Rinnegan became Sharingan/Sharingan can become Rinnegan is like saying that Homo Neanderthal evolved into Homo Sapiens and that Homo Sapiens can become Homo Neanderthal. This really is the best example I can make to explain my point.

The notion of Sharingan-Rinnegan evolving/devolving into each other is false, I don't understand why do we state that as fact.
