In this video we see how a wolf pack is organised. At the head are the old and/or infirm animals. They set the pace. Otherwise they would be left behind. Then come the young males whose job it is to defend the group. They are followed by the fertile females who ensure the future of the family. Then another group of young males to defend from behind. Finally comes the head of the family who controls and directs. Does human society have something to learn?
