I am human, hear me roar: Judging formidability from human vocalizations

(Cell Press) Many animals use vocalizations to judge one another's size and physical formidability when in competition for mates or other resources. Now, researchers reporting in the journal iScience have found that humans can use nonverbal vocal cues, including aggressive roars, in a similar way. The new evidence shows from a vocalization alone, human listeners can estimate whether another person is stronger or weaker or taller or shorter than they are with a high degree of accuracy.
