PLAY IS A SERIOUS BUSINESS Does play help develop bigger, better brains? Bryant Furlow investigates A. Playing is a serious business. Children engrossed in a make-believe world, fox cubs play-fighting or kittens teaming a ball of string aren’t just having fun. Play may look like a carefree and exuberant way to pass the time before the hard work of adulthood comes along, but there’s much more to it than that. For a start, play can even cost animals their lives. Eighty percent of deaths among juvenile fur seals occur because playing pups fail to sport predators approaching. It is also extremely expensive in terms of energy. Playful young animals use around two or three per cent of energy cavorting, and in children that figure can be closer to fifteen per cent. ‘Even two or three per cent is huge,’ says John Byers of Idaho University. ‘You just don’t find animals wasting energy like that,’ he adds. There must be a reason. B. But if play is not simply a developmental hiccup, as biologists once thought, why did it evolve? The latest idea suggests that play has evolved to build big brains. In other words, playing makes you intelligent. Playfulness, it seems, is common only among mammals, although a few of the larger-brained birds also indulge. Animals at play often use unique signs – tail-wagging in dogs, for example – to indicate that activity superficially resembling adult behavior is not really in earnest. In popular explanation of play has been that it helps juveniles develop the skills they will need to hunt, mate and socialise as adults. Another has been that it allows young animals to get in shape for adult life by improving their respiratory endurance. Both these ideas have been questioned in recent years. C. Take the exercise theory. If play evolved to build muscle or as a kind of endurance training, then you would expect to see permanent benefits. But Byers points out that the benefits of increased exercise disappear rapidly after training stops, so many improvement in endurance resulting from juvenile play would be lost by adulthood. ‘If the function of play was to get into shape,’ says Byers, ‘the optimum time for playing would depend on when it was most advantageous for the young of a particular species to do so. But it doesn’t work like that.’ Across species, play tends to peak about halfway through the suckling stage and then decline. D. Then there’s the skills-training hypothesis. At first glance, playing animals do appear to be practicing the complex maneuvers they will need in adulthood. But a closer inspection reveals this interpretation as too simplistic. In one study, behavioral ecologist Tim Caro, from the University of California, looked at the predatory play of kittens and their predatory behavior when they reached adulthood. He found that the way the cats played had no significant effect on their hunting prowess in later life. E. Earlier this year, Sergio Pellis of Lethbridge University, Canada, reported that there is a strong positive link between brain size and playfulness among mammals in general. Comparing measurements for fifteen orders of mammals, he and his team found large brains (for a given body size) are linked to greater playfulness. The converse was also found to be true. Robert Barton of Durham University believes that, because large brains are more sensitive to developmental stimuli than smaller brains, they require more play to help mould them for adulthood. ‘I concluded it’s to do with learning, and with the importance of environmental data to the brain during development,’ he says. F. According to Byers, the timing of the playful stage in young animals provides an important clue to what’s going on. If you plot the amount of time juvenile devotes to play each day over the course of its development, you discover a pattern typically associated with a ‘sensitive period’ – a brief development window during which the brain can actually be modified in ways that are not possible earlier or later in life. Think of the relative ease with which young children – but not infants or adults – absorb language. Other researchers have found that play in cats, rats and mice is at its most intense just as this ‘window of opportunity” reaches its peak. G. ‘People have not paid enough attention to the amount of the brain a
