20．In Africa，wild baboons（狒狒） like banding together to find food and protect each other．They may not be the smartest species，but like all animals，survival instincts（本能） are programmed into their DNA．They know that being together makes them safer．
Now think about your school．Sure，no one is trying to eat you alive，but you too are a social animal．And you are one who has been thrown into a fierce environment．From day one，you sense that there's safety in numbers．And once you follow that animal instinct to form packs，you feel more secure．"When I first walked into my new high school last year，I was so nervous，"says Mike，15，a high school student in New York City．"Everyone sat and walked together，in twos or threes-sometimes as a‘group'of five or more people．I didn't understand how I would ever belong．"
Mike isn't alone．In a survey，63percent of teens told us they feel pressure to fit in or be popular，and 91percent said their schools are divided into groups．
It is believed that to be popular is to be liked．But all popular people aren't necessarily liked．They just make rules．Popular groups aren't the only ones making rules．Zoe，a freshman from New York，says that even her close crew，which calls itself the"booknerds（書(shū)呆子），"has unspoken guidelines．When Zoe wears makeup or a dress，her friends act like she's betrayed them："They'll say，‘Oh，she's painting her nails．She's a popular girl now．'They're joking，but they're not，if you know what I mean．It makes me upset．"
"Because of the way the teen brain works，differences are seen as threatening，"says researcher Alexandra Robbins．"But usually these differences are things that make a person successful in adulthood．"
Take，for example，Adam Levine of the band Maroon 5．In high school，he was a"nerdy，awkward kid crazy about music．"Now he's successful and famous．Then there's Taylor Swift：Instead of trying to fit in with the cool kids who rejected her，she put her energy into songwriting．
