Many animals find it advantageous, even essential to live in social groups in which recognizing friends and respecting the power of rivals is vital. However, there will inevitably be squabbles over food, disputes over nesting places, arguments over mates. It is to the advantage of each individual that such disputes should be settled with a minimum expenditure of time and energy. In short, animal communities work more efficiently if they have some form of social structure. In such animal societies strict codes of behavior and sets of tasks are followed for the good of all. Sometimes tender friendships develop and care for the bereft and wounded is provided.
