Study: Man's Voice Reveals his fighting ability to other men

Just hearing the sound of a man's voice, no matter what he is saying, communicates all of this information and more, according to the study, published in the latest Proceedings of the Royal Society B.

The findings put men on vocal par with red deer, common loons, baboons, croaking gourami fish, owls and other animals whose calls also directly communicate body strength and fighting ability.

"Ancestrally, a man's fighting ability would have been much more important to know as archaeological and anthropological evidence indicates that men were much more likely to engage in aggression than women were," Aaron Sell, lead author of the paper, told Discovery News.

"For that reason, it's very important to know how formidable a man is," added Sell, a researcher in the Center for Evolutionary Psychology at the University of California, Santa Barbara.
