Researchers tested people’s understanding of the ten most common gestures used by chimpanzees and bonobos through an online game. More than 5,500 participants were asked to watch 20 short videos of monkey movements and choose the meaning of the movement from among four possible answers.
It turned out that the participants interpreted the meaning of chimpanzee and bonobo movements correctly more than 50% of the time. The results suggest that even though we no longer use these gestures, we may have understood this ancestral communication system.
