　　【Paragraph 6】Play allows a young animal to explore its environment and practice skill in comparative safety since　　the surrounding adults generally do not expect the young to deal with threats or predators. Play can also provide practice　　in social behaviors needed for courtship and mating. Learning appropriate social behaviors is especially important forspecies that live in groups, like young monkeys that needed to learn to control selfishness and aggression and to　understand the give-and-take involved in social groups. They need to learn how to be dominant and submissive because　each monkey might have to play either role in the future. Most of these things are learned in the long developmentalperiods that primates have, during which they engage in countless play experiences with their peers.(Role of Play in Development)
