Do Animals Know Right from Wrong? Pt 1

But does the dog really know he misbehaved, or is he just trying to look submissive because his owner is yelling at him? In another new video from the BBC "Frozen Planet" series, Adelie penguins are seen gathering stones to build their nests. One penguin stealthily steals a stone from his neighbor's nest every time the neighbor goes a-gathering. Does the penguin thief know its covert actions are wrong? These are some of the scenarios that interest ethologists, or scientists who study animal behavior. For years, these scientists categorically ruled out the possibility that animals might have a sense of morality — that they know right from wrong. Lately, though, the tide is turning. "People used to like to make that stark division between human and nonhuman animals," said ethologist Marc Bekoff. "But there's just no doubt that the scientific evidence for animal morality is accumulating as more and more animals are studied." [6 Amazing Videos of Animal Morality] Justice for all Bekoff is a professor emeritus of ecology and evolutionary biology at the University of Colorado, Boulder, and co-founder (with primatologist Jane Goodall) of Ethologists for the Ethical Treatment of Animals. His extensive field research has led him to believe that morality is an evolved trait, rather than a system created by humans, and that it evolved early in the history of mammals. "It has only been observed in certain species, because it really hasn't been studied extensively, but I would expect that moral sentiments would be fairly widespread among mammals," Bekoff told Life's Little Mysteries, a sister site to LiveScience. Much of Bekoff's research has focused on wolves and coyotes — both of which live in tight-knit groups governed by strict rules. Bekoff has observed acts of altruism, tolerance, forgiveness, reciprocity and fairness among wolves and coyotes, and says many of these moral sentiments are evident in the way the animals play with one another. Canids (animals in the dog family) learn social codes of conduct at a young age through play. They first invite one another to roughhouse using a "play bow": They lie down on their forelimbs while standing on their hind legs. Even when this is followed by aggressive actions such as growling and snarling, the bow makes their playful intentions clear. During play, dominant members of the pack will engage in role reversal with weaker ones, rolling over on their backs to give low-status playmates a chance at "winning," as well as lessening the force of their bites to prevent injury. If one playmate accidentally bites another too hard, it "apologizes," play-bowing again to show that it is still playing, despite the slip-up. Breaking these rules of engagement — or other rules, such as taking more than one's fair share of food — is serious business among wolves and coyotes. "There is a consequence of being labeled a cheater," Bekoff said. Others stop bonding with the "immoral" pack member, and eventually it wanders away from the group, usually resulting in an early death because it no longer receives the benefits of pack living. Bekoff believes the rules governing pack behavior offer a glimpse of the moral code that allowed early human societies to function and flourish. Dogs evolved from wolves, and seem to have maintained a wolfish sense of fairness. "They do have a sense of right and wrong. You see it when they play at the dog park, for example; when a dog asks another dog to play — even if it is larger and may be dominant — it's going to be honest about it. It knows it would be unfair to ask a dog to play and then beat it up or try to mate with it," he said.
