Summary:
- Chimpanzees, our closest living relatives, have long been known to communicate in complex ways, but new research has provided even more evidence of their sophisticated communication abilities.
- Researchers have found that chimpanzees use a variety of vocalizations, facial expressions, and gestures to convey information about their environment, their social relationships, and their emotional states.
- This research suggests that chimpanzees have a rich inner world and are capable of understanding and responding to the communication of their peers, which has important implications for our understanding of the evolution of human language and communication.
