Chimpanzees recognized when collaboration was necessary and chose the best collaborative partner
    
In the animal kingdom cooperation is crucial for survival. Predators hunt in prides and prey band together to protect themselves. Yet no other creature cooperates as successfully as we do. But where did this ability come from, and is it uniquely human? In a new study to be published in Science on 3 March 2006, Alicia Melis and co-authors from the Max Planck Institute for Evolutionary Anthropology, Leipzig, Germany show that our close relatives, chimpanzees, are much better cooperators than we thought.
