Formation of social groups is the outcome of reflexive co-operation, while the life of ants, bees, waps, lines etc., provide the best examples of instinctive co-operation. From the most primitive to the most sophisticated community, through the world, we come across some or the other form of co-operation among the people living in particular area or region it may be for some agricultural operations or for some social, economic or political activity.
