I should of stated who I was addressing in Tau, as I was backing your input. Basically from that, I could deduct that those with the Byakugan are the farthest from "mere human" in the ninja world. I mean, pretty much no one is mere human, but that could explain why you're either born with it or you're not. Maybe the same with Shikotsumyaku users, as their body structure is much different.
