Men - Lower voice

Since men were for the hunter jobs, they are call scattered in the hunting ground, one or one group may be far from each other. They have to communicate among themselves to work as a big team for hunting ( Like what wolves tactics )

Lower voice is more effective to transmit the voice to a further place compared with higher voice
That's why men got lower voice.

For women, while men is lower, women is higher relatively.

There is a theory that, not sure, is, higher pitch can draw one's attention easily
That's useful in raising kids to draw their attention to their moms.
Of course, higher pitch to attact males too
