The Totem group was the real social unit of the aboriginal Australian. The Totem is HP0-S18 not an Australian word but it is generally accepted to designate the name of an institution which is found everywhere among primitive people. The Totem group is primarily a group of people distinguished by the sign of a JN0-532 natural object, such as an animal or tree, who may not intermarry with one another — this is the first rule of primitive social organization; its origin is lost in antiquity ("Alcheringa") but its object is certainly to prevent the intermarriage of close relatives. Marriage takes place between men and women of different Totems; the husband belongs to all the women of his wife's totem and the NS0-163 wife belongs to all the men of the husband's totem at the same time that a communal marriage is established between the men and women of the two different Totems - the men and women being of the same generation. This presents a most valuable objective lesson in testing king social history. There are no unmarried couples; marriage for them is part of the natural order into which they are born.
