This probably isn’t where you wanted that statement to go but it caused me to think about how widespread the mating dominance hierarchy is. With some. like bucks in rut it even leads to physical combat. Cooperation exists in packs of wolves and prides of lions which also have a dominance hierarchy.
As a Buddhist, my man with a hammer tendency might surprise you; similarity, causation and interdependence. This does not lead me to think that just because other animals do it that it is natural for humans. I think that the ratio of proportion of dominance and cooperation is ever changing. I can’t think of many things that are not cyclic.
I don’t think that we are doomed to a dominance society for ever even though the cycle appears to be long. After a nuclear war at first people will kill each other for supplies to stay alive because they are not prepared for such a rapid change in the world. If mankind is to continue at some point cooperation may become far more dominant. Of course we can hope for other things, less dreadful to be the catalyst.
The point of my rambling is that I think humans are more flexible in our ability to adapt through change more rapid than the evolutionary path to solve threats to our existence. If my view of the cyclic nature of all things is true, a more egalitarian society is on its way. Again, hopefully without war or the other ancient calamities. The cause of change is often more complex than we think, without a single root cause. Perhaps it will take a number of drivers, including the awareness thing that I so often protest is too obvious to dwell upon constantly.
