Why would a society need a chief or shaman? Conflict resolution. With a small (100 or less) band of humans, there's no need for this because they all know each other, and they need to work together to survive. However, to support a larger group of humans, you must have a society that relies largely on farms for a food supply, therefore forming a city around the farms. With this larger society comes more contact between strangers, which creates conflict, and thusly a need for a chief or shaman.
