Final answer:
Vervet monkeys respond differently to different predator calls, suggesting a complex, potentially language-like communication system and learned behavior. Harlow's study on rhesus monkeys underscores the importance of social comfort, indicating learned behavior could influence vervet monkeys as well. Experiences such as predator encounters and social interactions are significant in shaping animal behavior.
Step-by-step explanation:
The behavior of vervet monkeys can be explained by examining their responses to different predator calls. When vervet monkeys hear a "leopard" call, they react by climbing high into the trees, which is a survival response to avoid ground predators. Similarly, upon hearing an "eagle" call, they seek shelter under bushes to hide from aerial threats. A "snake" call prompts them to stand on two legs and search the ground for snakes. This evidence strongly indicates that vervet monkeys possess a complex communication system that acts as an early warning signal, which could be construed as a form of language. They certainly distinguish between different types of threats and respond accordingly through learnt behavior, showing that they are not acting solely on instinct but may also have learned these responses from their group.
Regarding Harlow's study, it became clear that social comfort is crucial in the development of rhesus monkeys, even surpassing the immediate need for food sometimes. The study implies a learned aspect of this behavior, supporting the idea that, like rhesus monkeys, vervet monkey behaviors could also be influenced by learned preferences.
Understanding the impact of experiential factors on animal behavior, vervet monkeys may also exhibit learned preferences in their food selections and responses to predators. These observations align with the notion that experiences, such as social interactions and predator encounters, substantially affect animal behavior.
