Good news for those of us who see mutual cooperationas evolutionary.However, the term 'reciprocal altruism' is oxymoronic inEnglish.  'Altruism' is doing something for another's sakewithout expected benefit to one's self.  A betterdescription is the one from the article above, viz.,"calculated reciprocity".Craig
