Final answer:
Chimpanzees and gorillas in the wild exhibit behaviors related to displacement in their social structures and a certain degree of productivity in communication, but their communication systems do not match the complexities of human language.
Step-by-step explanation:
Chimpanzees and gorillas, in their natural habitats, display behaviors related to displacement and productivity in their communication methods to a certain extent. However, their communication systems lack the flexibility and complexity of human language. In the study of primates like those in Gombe National Park in Tanzania, researchers have observed that chimpanzees exhibit different hunting techniques and tool usage, which can be influenced by their environment, such as the rainforest versus the grassy savannah.
Differences in behavior also extend to how nonhuman primates interact within their social structures. For example, gorillas and chimpanzees organize themselves into family groups, and gorillas, in particular, have a dominant male leader. These social behaviors demonstrate an aspect of displacement, where the actions and communications within the group are related to social hierarchy and organization, which extends beyond the immediate context.
Nevertheless, when it comes to productivity, the innate communication system of these primates in the wild is quite limited compared to human language. While human-reared great apes have learned to use gestures or tokens in a rule-based way, possibly indicating a basic capacity for protolanguage, it is still unknown to what extent this is due to innate abilities or learning. In their natural environment, wild chimpanzees have been found to produce diverse vocalizations, but these calls tend to have fixed and limited meanings, contrasting with the flexible and infinite nature of human language.
