The ideal male voice is low pitched, thundering, guttural and with a degree of rasp. Males with voices and females preferring males with such voiced may have evolved due to the higher chance of intimidating predators and rival tribes with impressive shouts, whereas males without this trait were less intimidating and thus less likely to scare off rival tribes or predators, and thus had lower reproductive success.
A deep voice is caused by thick vocal cords, as well as being larger in size (generally, the larger the animal, the lower the pitch) and having a wider ribcage which is related to a wider frame and strength which are all masculine traits.
