Is there any such thing as naturally nocturnal human?

Not any vampirish stuff going on here. Is there any natural reason some people would be drawn to the night? Not a condition that needs to be corrected like a shifted or elongated circadian rhythm, but an actual need for this type of person to exist? Maybe not now, but ages ago and has been passed down?

Say if a child as young as age 2 exhibited traits of staying up late into the night despite best the best efforts of her parents to get her to sleep and this persists through adulthood and develops into a desire, possibly even a need, for her. Is there any explanation other than it is not normal and needs to be corrected? Could it, somehow, for some reason, for some group of people, actually be normal? Be the way they are meant to be just as much as they are meant to have blue eyes or two feet? If so, why? Any thoughts on why?
