I wouldn't exactly call this an evolutionary advantage for humans, though, would you?
I mean I don't think I've ever navigated to somewhere by my nose. On second thought, though, I do have a good sense of where north is all the time.

Maybe its a sense we once had that proved redundant? Who knows. :-)

Evolution is used to explain everything for you guys. Actually it does not
explain anything.
christianity for example evolved from judeism which evolved from noahide religion which evolved from abrahamic religion which evolved from babylonian religion which evolved from sumerian religion.
you're welcome.

They are not the same thing, and it's best we don't mix the two.

that do know should take pains to clarify not confuse the situation.
Evolution is a word that gets used for many things that it has nothing to do with, and when
someone asks about evolution in the correct context of biology, then I think moving beyond
that is unhelpful.
Creationists do a good enough job deliberately confusing people without help.

Do you think ancient man even understood what "north" is? And/or how it related to what he saw with his eyes? Was it obvious to ancient man that the world was round and could he have envisioned a map of it? Or even just his "neighborhood"? Furthermore, how could he use it to describe to another where the herd or a kill was? It's likely he just did a lot of pointing using visual clues. The oldest maps just used graphical depictions of the things he saw in his environment. And they certainly were not always oriented with north at the top.

Creatures that have a magnetic sense when blinded still travel in strait lines because they can still navigate

But the whole concept of "evolutionary advantage" kinda goes out the window when you add being blind on top of it. Blind cavemen stumbled off cliffs and into wild animals. Blindness would more than outweigh any evolutionary advantage given by magnetoreception. This is primarily why we learned to be diurnal.
