Feelings of righteous indignation, it seems, are not the preserve of people alone, Refusing a lesser reward pletely 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 form the mon ancestor that the species had 35 million years ago, is, as yet, an unanswered question.21.

Yet pleasure at your own can vanish if you learn that a colleague has been given a bigger one. Indeed, if he has a reputation for slacking, you might even be outraged. Such behaviour is regarded as “all too human”, with the underlying assumption that other animals would not be capable of this finely developed sense of grievance. But a study by Sarah Brosnan and Frans de Waal of Emory University in Atlanta, Georgia, which has just been published in Nature, suggests that it all too monkey, as well.The researchers studied the behaviour of female brown capuchin monkeys. They look cute. They are goodnatured, cooperative creatures, and they share their food tardily. Above all, like their female human counterparts, they tend to pay much closer attention to the value of “goods and services” than males. Such characteristics make them perfect candidates for Dr. Brosnan39。s and Dr. de waal39。 study. The researchers spent two years teaching their monkeys to exchange tokens for food. Normally, the monkeys were happy enough to exchange pieces of rock for slices of cucumber. However, when two monkeys were placed in separate but adjoining chambers, so that each could observe what the other was getting in return for its rock, their behaviour became markedly different.accept the slice of cucumber Indeed, the mere presence of a grape in the other chamber (without an actual monkey to eat it) was enough to reduce resentment in a female capuchin. nature. 　　[C]. monkeys, like humans, tend to be jealous of each other. 　　[D]. no animals other than monkeys can develop such emotions.23.
