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.

The book, by the way, is Wild Justice: The Moral Lives of Animals by Marc Bekoff and Jessica Pierce.
