Little is known, however, about how 文化 groups form or the 演化ary forces behind group affiliation and ingroup favoritism. Hence, we examine these forces experimentally and show that arbitrary symbolic markers, though initially meaningless, evolve to play a key role in 文化 group formation and ingroup favoritism because they enable a 族群 of heterogeneous individuals to solve important coordination problems. This process requires that individuals differ in some critical but unobservable way and that their markers be freely and flexibly chosen. If these conditions are met, markers become accurate predictors of behavior. The resulting 社會 environment includes strong incentives to bias interactions
