Byakugan, Sharingan, Rinnegan, Rinne Sharingan, Wood Release and Shikotsumyaku all have a origin. The others like Ice Release or in this case Mud Release don't. Genetics, Mutation and Evolution all follow the simple rule of cause and effect. As long as there is no 'cause' a.k.a a mutation in already existing Genetics their won't be an effect a.k.a an advanced nature. That's not actually correct. The Expansive Truth-Seeking Ball Kaguya created was stated to host all of the existing KKG, which means that Kaguya and God Tree are the true origin of all, not only the mentioned ones. So they follow the rule of special abilities being passed on from generation to generation just like the Sharingan or Byakugan do, they aren't random mutations popping out from nowhere.
