25、 of string arent 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 theres 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

26、 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 idah

27、o university. you just dont find animals wasting energy like that, he adds. there must be a reason.新浪微博：新浪微博： 李威廉李威廉ieltsieltsb. 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 oth

28、er 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 rea

29、lly 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 q

30、uestioned in recent years. 新浪微博：新浪微博： 李威廉李威廉ieltsieltsc. 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,

31、 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 doesnt work like tha

32、t. across species, play tends to peak about halfway through the suckling stage and then decline. 新浪微博：新浪微博： 李威廉李威廉ieltsieltsd. then theres the skills- training hypothesis. at first glance, playing animals do appear to be practising the complex manoeuvres they will need in adulthood. but a closer ins

33、pection reveals this interpretation as too simplistic. in one study, behavioural ecologist tim caro, from the university of california, looked at the predatory play of kittens and their predatory behaviour when they reached adulthood. he found that the way the cats played had no significant effect o

35、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 mo

36、uld them for adulthood. i concluded its to do with learning, and with the importance of environmental data to the brain during development, he says. 新浪微博：新浪微博： 李威廉李威廉ieltsieltsf. according to byers, the timing of the playful stage in young animals provides an important clue to whats going on. if you

37、 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

38、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. 新浪微博：新浪微博： 李威廉李威廉ieltsieltsg. people have not paid enough attention to

39、the amount of the brain activated by plays, says marc bekoff from colorado university. bekoff studied coyote pups at play and found that the kind of behaviour involved was markedly more variable and unpredictable than that of adults. such behaviour activates many different parts of the brain, he rea

40、sons. bekoff likens it to a behavioural kaleidoscope, with animals at play jumping rapidly between activities. they use behaviour from a lot of different contexts predation, aggression, reproduction, he says. their developing brain is getting all sorts of stimulation. 新浪微博：新浪微博： 李威廉李威廉ieltsieltsh. n

41、ot only is more of the brain involved in play that was suspected, but it also seems to activate higher cognitive processes. theres enormous cognitive involvement in play, says bekoff. he points out that play often involves complex assessments of playmates, ideas of reciprocity and the use of special

42、ised signals and rules. he believes that play creates a brain that has greater behavioural flexibility and improved potential for learning later in life. the idea is backed up by the work of stephen siviy of gettysburg college. siviy studied how bouts of play affected the brains levels of particular

43、 chemical associated with the stimulation and growth of nerve cells. he was surprised by the extent of the activation. play just lights everything up, he says. by allowing link-ups between brain areas that might not normally communicate with each other, play may enhance creativity. 新浪微博：新浪微博： 李威廉李威廉ieltsieltsi. what might
