Thanks for sharing that, although it's really our beliefs that come out of patriarchal culture (only 6-9K years old) that we are projecting. Modern foragers live a lot like what you are describing with horses, where the tribe makes most of the decisions together and sometimes one person takes the lead for a particular situation, and later someone else does for something else. Hierarchy is an integral part of most primate cultures but it is believed that humans suppressing this inclination to create greater enforced egalitarianism was a central element of human evolution - one that allowed us to develop way beyond our primate cousins.
