Frans de Wall , the answer lies in one word: empathy, specifically, or concern for the welfare of others. Even when the other does not belong to the same species as itself. We have seen in a zoo, a Bengal tiger feeding piglets. A bonobo hoist a lifeless bird on top of a tree to try to make it fly. Or a chimp back in the water a duckling manhandled by young monkeys.
Animals empathetic
C is a scene of everyday life. A blind, disoriented, looking his way. A psychic comes to his aid, guiding voice. The cripple thanked by loud effusions. Ordinary scene, except that it happens Thailand, in a natural park, and both protagonists are female elephants. This example is one of those whose new book is full of

entitled The Age of Empathy
, this fascinating lesson, pushing the boundaries between man and animal, is also a plea for "living together" for use of our societies.
"Greed lived, empathy is required, the author proclaims
. We need to completely revise our assumptions about human nature." To those
, economists and politicians, who believe the only authority in the struggle for survival - and, according to the misguided interpretation that Social Darwinism gave the theory of evolution by selection of the best performing individuals - he opposes another principle, equally active than the competition: empathy. That is to say, the sensitivity to the emotions of another. A compassionate faculty who, far from being the prerogative of man, is shared by many mammals, beginning with primates, elephants and dolphins. And, moreover, is as old as the hills. In his
the most rudimentary forms, or more archaic, it manifests itself through imitation, or synchronization of behavior: just as we applaud the same tempo as our neighbors at the end of a concert, two walkers give the length their steps, or that old couple eventually look like a dog sled moves as a single body, a chimp yawns at the sight of a conspecific is picking up the jaw and laughed when the other s' laughed. Better still, the contagion crossed the species barrier: a rhesus monkey and baby it reproduces the movements of the mouth of a human experimenter.
But empathy is more sophisticated expressions. In the Thai National Park in Côte d'Ivoire
, chimpanzees have been observed licking the blood of comrades attacked by leopards, and slowing the pace to allow the wounded to follow the group. In the same community have been described several cases of adoption of orphans by adult females but also males. A concern that may seem natural for social animals, which are a collective interest to cooperate.
How to explain, however, when the individual has nothing to gain empathic behavior, which then becomes strictly altruistic? Experience has shown that rhesus monkeys refused for several days, pull a string releasing the food if the action sent an electric shock to a companion they saw the seizures. Preferring to endure hunger, assisting at the suffering of a kind.
In its simplest form, the "sympathy" animal - a term used by Darwin himself - not only mobilizes cognitive complex deemed proper to man. It involves, outlines the ethologist, pure emotional mechanisms. Mice thus more sensitive to pain when they saw others suffer mice in which they are familiar. However, cognitive processes come into play modes of compassion more complex, requiring to put in place of another. Like when a chimpanzee abandoned his occupation to come to comfort a fellow assaulted during a brawl.
Compassion take its roots in an evolutionary process lointain, à une période bien antérieure à l'espèce humaine, avec l'apparition des soins parentaux.
"Pendant 200 millions d'années d'évolution des mammifères, les femelles sensibles à leur progéniture se reproduisirent davantage que les femelles froides et distantes. Il s'est sûrement exercé une incroyable pression de sélection sur cette sensibilité"
, suppose le chercheur. Voilà pourquoi les mammifères, dont les petits, allaités, réclament plus d'attention que ceux d'autres animaux, seraient les plus doués d'empathie. Et les femelles davantage que les mâles. Un trait que partageaient peut-être les derniers grands reptiles. Ce which would explain why some birds - likely descendants of dinosaurs - also seem to show pity. The heartbeat of a female goose is accelerating and, flying wildly when her mate is attacked by another waterfowl. The ethologistdoes not pay to much in the otherworldliness. Like other animals, "there is in man a natural inclination to competition and aggression" . But his propensity for compassion is "equally natural" . Still, empathy is not always virtuous. It is also the ability to feel the emotions of others that are based cruelty and torture.
