After an introduction to life-history theory, and before turning to humans, the author reviews research about the two mammals in which play has been studied the most extensively: laboratory rats and monkeys. He looks at the development of play, deprivation studies, gender segregation, and the functions of gender-differentiated forms of play. The gender segregation and sex differences in play parenting and rough-and-tumble play observed in many primates are also evident in children. Vigorous social-play benefits all children physically by developing strong bones and muscles, by promoting cardiovascular fitness, and by encouraging exercise habits that help prevent obesity. Unsupervised play also helpshone the skills of communication, perspective taking, and emotion regulation. For boys especially, rough-and-tumble play in early childhood provides a scaffold for learning emotion-regulation skills related to managing anger and aggression.

Contemporary evolutionary biologists think evolved patterns of play help children develop strong bones and fit bodies, acquire and practice a culture’s skills and values, learn to establish friendships and get along with peers, and control impulses and emotions. The positive emotions play invokes encourage children to explore the environment, to try out new behaviors, and to learn with more flexibility—all of which helps prepare them for the unexpected (Panksepp 1993; Spinka, Newberry, and Beckoff 2001). However, in the United States and in much of the rest ofthe developed world, we have witnessed a dramatic decline in the opportunities for children to engage in vigorous social play away from adult control (Gray 2011). Thus, questions about possible functions  \n464  \nAmerican Journal of Play, volume 3, number 4. © 2011 by The Strong.

Mothers and teachers often frown on all of these, especially when played indoors. I begin with an introduction to life-history theory because each species has its own unique social ecology and historical development. We need an understanding of the challengesand opportunities a particular species faces to understand why play evolved in the particular form it did in that species. Because similar patterns of vigorous social play appear in many species, we can use comparative analyses to explore its adaptive functions in relation to species differences in social ecology and life history, as well as in age and gender within species. I precede my discussion of play in children with an overview of the mammals for which play has been studied most extensively: rats and monkeys. I review the development of play and experimental deprivation studies in which the potential benefits of play are inferred from animals deprived of it, for which there is no close parallel inhuman research. I also examine gender segregation and sex differences in play in relation to the specific functions that gender-differentiated forms of play serve in monkeys. I then describe developmental and cross-cultural patterns of play in children with particular attention to gender segrega","cbCaibbaBkN1W0m8","https://ap.wps.com/l/cbCaibbaBkN1W0m8","pdf",141732,25,"English","# An Evolutionary Perspective\n## Life-history theory and evolutionary origins\n## Development and comparative evidence from rats and monkeys\n## Gender segregation and sex differences in play\n## Physical and emotional health benefits in children\n## Emotion regulation as a specific adaptive function","[{\"question\":\"What does life-history theory contribute to understanding social play?\",\"answer\":\"Life-history theory provides a framework for explaining how species-typical traits guide somatic and reproductive efforts across an organism’s life.
