2017年同等学力申硕英语考前练习之翻译(22)

　　The researchers suggest that capuchin monkeys，like humans，are guided by social emotions.In the wild，they are a cooperative，group-living species.Such cooperation islikely to be stable only when each animal feels it is not being cheated. Feelings of righteous indignation，it seems，are not the preserve of people alone. Refusing a lesser reward completely makes these feelings abundantly clear to other members of the group. However，whether such a sense of fairness evolved independently in capuchins and humans，or whether it stems from the common ancestor that the species had 35 million years ago，is，as yet，an unanswered question.

　　研究人员暗示，和人类一样，僧帽猴也受社会性情感的支配。在野外，它们是协作、群居的物种。只有在每个动物都觉得它没有受到欺骗时，这种协作才有可能稳定。如此看来，正当的愤怒感并非人类所特有的。完全拒绝较小的奖励使得群体的其它成员非常清楚这些情感。不过，到现在为止，这种公平意识是否在僧帽猴世界和人类社会独立演化，还是源于3500万年前他们的共同祖先，这仍然是一个“悬而未解”的问题。
