[Mario] Why is Peach human?

The population of her kingdom is like 99% mushroom-people (is Toad the name for the the entire species?) it's even called the Mushroom Kingdom. How did they end up with a human monarch?

Unclear, she rules along with her father who is also human and appeared very little mostly in the early games. Her mother is never mentioned, but is presumed human. It seems likely they're outside travelers like Mario who rose to the task of helping the inhabitants of the kingdom which seems likely since that's what Mario and several other humans do for the mushroom kingdom over the course of the games.

So presumably they helped and were made rulers or the help was literally to rule over them because they were super-qualified. Of which the place seems like a damn utopia when it's not being invaded, so kudos. When is is getting invaded you get a delightful pyromaniacal jump-murderer to solve your problems.

Though Peach has exhibited all the powers and adaptability Mario has, in addition to her own magic. She jumps quite a bit less well, but in addition to her magic she seems to be able to naturally fly/float. So.... If she's not kidnapped she can generally murder her own problems away, which she does in several games.
