Can chimps show their moods?
|
Chimps are good at showing their moods and do so using the expressions on their faces. The shape of the mouth and whether or not the teeth are bared are important signals. The chimps pictured above are showing (1) a desire to play, (2) how they beg for food, (3) fear, and (4) anxiety. | | The four most common facial expressions seen in chimps |
