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.

　　④ Feelings of righteous indignation, it seems, are not the preserve of people alone.

　　⑤ Refusing a lesser reward completely makes these feelings abundantly clear to other members of the group.

　　⑥ 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.
