Monkeys have a sense of moral awareness

Everyone knows it, but then again sometimes the simplest things are the ones you notice last.

..."The animals were asked to perform a set of simple tasks and then rewarded with food or affection. The rewards were varied, seemingly at random. De Waal found the animals had an acute sense of fairness and objected strongly when others were rewarded more than themselves for the same task, often sulking and refusing to take part any further.

Another study looked at altruism in chimps - and found they were often willing to help others even when there was no obvious reward. “Chimpanzees spontaneously help both humans and each other in carefully controlled tests,” said de Waal."
