This document discusses how power vectors influence group development in humans and other social animals. It notes that groups often organize with a leader-follower structure, concentrating power in the leader. The group members initially assess characteristics like determination and problem-solving ability to select the best leader. This power vector arrangement can be an effective survival strategy, but may fail if the leader and supporters lose focus on the group's interests. The document reviews literature on ecology, zoology and other fields to analyze how power dynamics function in groups and the role of power vectors in organizing these structures.
