Biologists have long debated the evolutionary function of play in young mammals. Traditionalists argue that play serves primarily as physical training, allowing animals to hone the motor skills necessary for hunting and survival. In contrast, a newer school of ethologists proposes the "cognitive flexibility" hypothesis, suggesting that the true evolutionary benefit of play is to prepare the developing brain to handle unexpected social and environmental situations. While the physical training hypothesis accounts for basic forms of play, the cognitive flexibility model offers a far more comprehensive explanation for the highly erratic and varied play behaviors observed across mammalian species.
