New research shows that elephants can differentiate between ethnicities and genders and can tell an adult from a child. They can do this, according to the researchers, all from the sound of a human voice.
Prof. Karen McComb and Dr. Greame Shannon of the University of Sussex led the study, and said they found that the elephants could also sense threat by the sound of a human voice.
The BBC's Victoria Gill discusses the new research with Here & Now's Jeremy Hobson.
