Final answer:
Primates have the ability to communicate with different species within their social groups using gestures and tokens. The use of symbolic systems in cooperative interactions indicates a basic capacity for protolanguage.
Step-by-step explanation:
According to the movie 'Clever Monkeys,' primates have the ability to communicate with different species within certain social groups. Primates, including gorillas, chimpanzees, bonobos, and orangutans, have been taught to use gestures or tokens to refer to things around them. They combine these signs in a rule-based way to make comments and requests, indicating a basic capacity for protolanguage. While there is skepticism among linguists, the use of symbolic systems in cooperative interactions suggests that primates can communicate with different species within their social groups.
