I wish I could remember the name of a documentary I watched about primates a few years ago. It really lays bare how this process plays out in an accelerated manner because while humans are no longer polygamous, the underlying psychology is all basically the same. We humans just do a much better job of hiding it.
While I'm sure there is a small element of truth to this, to categorically accept it seems like reductive biological determinism. We are more than just primates.
