Scientists studying animal behaviour believe they have growing evidence that species ranging from mice to primates are governed by moral codes of conduct in the same way as humans. Until recently, humans were thought to be the only species to experience complex emotions and have a sense of morality. But Prof Marc Bekoff, an ecologist at University of Colorado, Boulder, believes that morals are “hard-wired” into the brains of all mammals and provide the “social glue” that allow often aggressive and competitive animals to live together in groups. He has compiled evidence from around the world that shows how different species of animals appear to have an innate sense of fairness, display empathy and help other animals that are in distress.
