Final answer:
The practice of pair bonding in primates varies across species. New World monkeys like tamarins and marmosets do form pair bonds, while many Old World monkeys do not, therefore the statement is false.
Step-by-step explanation:
Pair bonding in primates is a complex topic that varies greatly across different species. While New World monkeys, such as tamarins and marmosets, are known to form pair bonds and cooperatively raise their young, many Old World monkeys do not tend towards monogamous relationships. Hence, saying that pair bonding is commonly practiced by all primates would be false.
Primatologists have observed that primate social organization is multifaceted and often revolves around both male and female strategizing for resources, roles, and relationships. Although males often move between groups, in many species, the core of social life is formed by related female primates and their offspring, emphasizing kinship and solidarity. Cooperation and social bonds are key elements in primate societies, alongside the competition for survival and reproduction.
Given this complexity, the statement that pair bonding is commonly practiced by primates is False. The social structure of primates is diverse, with some species exhibiting pair bonding and others showing different forms of social relationships.
