Final answer:
Chimpanzees and gorillas, both of which live in social groups, exhibit behaviors that can be interpreted as protests against stealing.
Orangutans tend to live solitary lives and therefore do not commonly display such behaviors. These insights into primate behavior help us understand the complexity of their social structures and culture.
Therefore, the correct options are: 1) Chimpanzees and 2) Gorillas.
Step-by-step explanation:
Chimpanzees use tools, such as sticks, to gather food and can protest behaviors that disrupt their social norms. Gorillas, which also live in family groups led by a dominant male, can show signs of protest or discomfort when approached by other gorillas or feel their territory is encroached upon
Orangutans, which are solitary, do not display the same kind of social protest because they are less likely to encounter situations of stealing within a group context as they generally live alone.
Chimpanzees demonstrate various complex behaviors, some of which are thought to be learned within the context of their community. For example, there may be differences in behaviors between groups of chimpanzees based on their environments.
Gorillas, as well, have distinct approaches when they encounter each other or sense the presence of other gorillas, as a part of their social interaction protocols.
It is important to understand these behaviors as they can provide insight into the social structures and cultures of these primate species, which are closely related to humans, sharing numerous genetic and behavioral similarities.
