First off, gorillas were around before humans, and until very recently had almost no contact with people, so I don’t think they’ve “learned” anything from us. Also, most anthropologist today agree that shunning the dominance hierarchies of our primate cousins is the central adaptation of human beings - one that kept us alive when other hominid strains died out.
"But beyond intelligence and opposable thumbs, how did humans develop culture in such myriad, complex ways, when other brainy, dexterous species did not? Tests comparing young children, chimpanzees and monkeys suggest that collaboration, rather than competition, may be the key to human culture."
You don't even understand what patriarchy as a social system is or entails, so whether or not you believe in it is irrelevant (although then you go on to defend it as a good system, so which is it?). You also don't understand primate cultures either. Mostly, you don't actually understand anything you're trying to talk about.
"Our current usage of the term alpha to mean dominant, assertive, intimidating, and someone who imposes their will on others really doesn’t align with alphas in the animal kingdom.
It’s even possible for the smallest male in the group to be the alpha in chimpanzee society. “The smallest male, if he has the right friends and keeps them happy, or if he has female support, he can be the alpha male,” says de Waal. An alpha can be intimidating or vigorous, but he still must also have the right allies. Amongst chimpanzees, the alpha male also has to be generous because alpha status is conferred on the guy with the strongest coalition.
Alpha male chimps also have an obligation to keep the peace in the group. They try to prevent fights from breaking out, and typically support the underdog in any conflict, even if that means not favoring a relative or friend. This provides security for the lowest-ranking members of the group, which helps the alpha’s popularity. Alpha male chimps are also the ones who demonstrate the most empathic behavior, spending a lot of time comforting others. As de Waal characterizes them, alphas are the “consoler in chief.” In general, females demonstrate more of this sort of behavior, but the alpha male has been shown to be the top comforter of others in the troop."
The only sensible thing you've said is that it's good to use the skills of the people in your society, such as they are, toward the wellbeing of the society. That's what we did for 97% of human history and it kept us alive when other early hominids did not survive. No more Australopithecus, Homo erectus or Neanderthals. Only we survived. Because of leaderless, egalitarian, food sharing, communal child-rearing groups that developed wide networks of mutual benefit and cooperation with other leaderless, egalitarian, food sharing, communal child-rearing groups nearby. Humans are by far the most cooperative and willing to share with each other of all the primates. This is very literally the key to human evolution and developmental success.
"While the subjects worked on the puzzle box, the scientists observed each group to evaluate various behaviors—such as vocalizing, watching one another, imitation and sharing or stealing rewards. They also attended to the social rank, sex and age of subjects to assess their influence on how subjects learned. Overall, the children outperformed other primates at more difficult puzzle levels. Although all groups performed well at the first level, most chimps and capuchins were stymied by the second and third.
In short, only the children demonstrated cumulative learning. So what did the kids do differently? During the task they actively talked to, instructed and imitated one another. They were cooperative and even shared their rewards. These behaviors, which were not observed in either of the other two species, were therefore strongly correlated to success in solving the puzzle box. The researchers concluded that these so-called pro-social behaviors indicate the importance of social cognition in developing cumulative learning and culture. "There was so much more going on in the children," Laland says."
I'm not sure what movies you've been watching but there has never been a time in human history where humans lived in small packs controlled by an alpha male. Please provide some evidence of this being a widely accepted scientific fact and not just a figment of some movie director's imagination. Personal autonomy has always been a human value and it was one that held sway until very, very recently. Even early kings only had power in their immediate vicinity - out of sight, people did what they wanted to without consequences.
"Humans may not have begun their history in a state of primordial innocence, but they do appear to have begun it with a self-conscious aversion to being told what to do."
