Hierarchy was a powerful tool that evolved within species and between species. Within species, it evolved as a means to facilitate evolution by natural selection. Those members within a species that were higher up a hierarchy got to have more food, got to reproduce the most, and tended to be the most powerful. It allowed for organization and a chain of command that increased cohesion and effective power of a group of any given species, increasing their chances of survival.
Members of the species had genes that almost forced them to submit in the face of hierarchy, and it was precisely these genes that the Authority of Alpha exploited.
However, this only applied within a species.
