Answer 1

Scientists believe that the primary purpose of laughter in primates, especially during social interactions, is to **communicate during play**. Laughter serves as a social bonding mechanism, helping to reduce tension and promote positive interactions among individuals. It is often seen in contexts of play fighting and other playful behaviors, reinforcing social connections within groups. While various emotions and intentions can be conveyed in primate vocalizations, laughter specifically plays a key role in playful communication.
