1.) Hinde defines social interactions as any instant when one individual (A) performs behavior (X) to (B) and (B) does (Y) back again. An interaction may involve any number of repetitions with slight differences in the behavior being performed; an interaction may also be defined simply as content and a qualifier. A social relationship, as defined by Hinde, is the direct result of a series of social interactions that occur in a period of time; what happens during these interactions may affect what happens in future interactions and the organisms in question are said to have a social relationship. Finally when an organism involved in a relationship becomes involved in other relationships he or she is said to be involved in a network of relationships or social structure; a structure is described in terms of the properties of the constituent relationships and how those relationships are organized. 1.) Being in a large group enables monkeys to effectively defend an area of high quality fruit from a neighboring group. In addition to this, being in a large group also increases ones chances of survival; being in a larger group means that there are more eyes and ears available for detecting possible predators. In contrast, being in a large group may also hinder ones chances of survival; an increase in group size generally leads to a decrease in birth rates because there is more inter-group competition for resources. Strong bonds are typically made between females who are closely related because genetic relatives have a stake in each others reproduction; these bonds are usually made between mothers and daughters, pairs of sisters, and aunts and nieces. 2.) Female capuchins generally exchange grooming as well as coalitionary aid with each other. In terms of grooming, kinship plays a role with the selection of who grooms who but this only takes place in larger groups. In a smaller group, kinship is generally negated and grooming partners are chosen based on ones rank within the group. In addition to this, it has also been observed that most monkeys choose grooming partners based on their knowledge of who “owes” them and who is more likely to return the favor. In terms of coalitionary aid, the same rules apply; in small groups higher ranking individuals will give aid to other high ranked individuals but in small groups rank is not an issue and kin becomes the basis for selecting aid. 3.) In Macaques the acquisition of rank follows “younger-sister ascendancy rule” which states that a
