Answer:
A.) Examples of cooperative behaviors include warning calls and group hunting
This statement is true. Cooperative behaviors are commonly observed among primates, and they can take many forms, including sharing food, grooming, group hunting, and warning calls. These behaviors can benefit both the individual and the group as a whole, by increasing the chances of survival and reproductive success. It is also worth noting that not all cooperative behaviors are necessarily altruistic, as they can be motivated by various factors such as kin selection, reciprocity, or mutualism. Finally, cooperative behaviors are not limited to great apes and can be observed in many different primate species, including monkeys, lemurs, and tarsiers.
