Quote by: Technosoul  What is the evolutionary advantages to that difference in the pitch or sounds of a male from a female voice? |
Women have high pitched voices to call for help in time of distress, this comes out as a long ear piercing shriek, which will bring any males nearby to her aid.
It also could frighten the wits out of an assailant by its volume and pitch causing him to back off, so it could be self defensive as well.
