beards :

The key to remember is that we probably started with fully body hair, and a beard as we know it is simply an area that never lost that hair (or loss less). Hair was probably quite important to our ancestors for a variety of social/mating reasons, and when we starting shedding hair (for the heat-exchange advantage of bare skin coupled with sweat), arguably keeping some of it for other reasons, that didn't significantly hurt the heat-exchange advantage, is not really strange.

Some typically cited reasons for why it hung around:

- it differentiates physically mature males from their younger selves
remember, once we start hiding our...packages...having some other outwardly visible indicator is useful.

- as NCFY ponits out, can be a protection against the elements.
I don't think that indicates she never lived in a cold place, more so that she can't grow a beard
