Why are Animals Altruistic?
Researchers at the Laboratoire d’Écologie at the University Pierre and Marie Curie (Ecole Normale Supérieure/CNRS) and the Royal Holloway College (London, United Kingdom) have just explained the evolution of altruistic behavior in animals.
In nature animals have been observed cooperating, and the detection of a genetic predisposition to this type of behavior contradicts Darwin’s theory of evolution which predicts a better survival rate for the most selfish animals. The use of mathematic modeling has provided a new explanation for the surprising persistence of this type of behavior which appears, at first sight, to be detrimental to the animal adopting it.
