A commenter pointed to this article at Return of Kings:

Chimpanzees and bonobos are our closest evolutionary relatives with whom we share anywhere from 95 to 99 percent of our genes…. the two exist under a completely opposite social order. The chimpanzees organize themselves into a patriarchal order with the alpha male at the top… In the wild, chimpanzees exist as warrior tribes that go on regular patrols to guard their territory, engage in hunting expeditions, as well as fight wars with the other tribes. Bonobos, on the other hand, exist in a peaceful matriarchal order. Their tribes are ruled by group of females who form a sisterhood with an alpha female as their leader. Unlike their chimpanzee counterparts, the male bonobos are weak and ineffectual… Besides the matriarchal order—which is already unique among the primates—bonobos distinguish themselves as highly sexual species. They have frequent casual sex on a daily basis (albeit lasting only about ten seconds) in every way and every pairing imaginable. Sex is used to greet, bond, decrease stress, resolve conflicts, etc.

It goes on to basically detail every aspect of r/K without actually saying the words, “r/K.” You have r-selected Bonobos with sexualized Bonobo females using sex to control effete males, Bonobo homosexuality, Bonobo pacifism, and Bonobo matriarchies. On the other side, the chimps are exactly the opposite.

These are the types of brilliant passing observations of similarities that ultimately, inevitably, lead one to suddenly see r/K Theory beneath the surface. Obviously Bonobos have relatively free resources, while chimps have to fight for their’s. As you follow the threads, you ultimately find free or restricted resources leads you to the dopamine system’s malleability, the dopamine system leads you to the amygdala’s functions, the amygdala leads you to the reproductive traits of r/K, and r/K leads you to politics. Once you come full circle, there is no looking back, because each piece interconnects with, and reinforces, the other. Politics links to amygdala. Resources link to political trends. Amygdala activity links to resources. Rearing links to amygdala. Sex links to dopamine. Dopamine links to resources, and so on, and so on. It all interlinks.

Commenter Black Knight at RoK says:

I agree. It seems like the most devastating blows against masculinity have been done in the past 10 years. Sure, feminism has been around for decades, but only recently have men been turned in to complete pussies. That’s really sad.

Notice that 10 year time frame just about encompasses the $12 Trillion in conjured money Obama has borrowed in the name of the US and given away, plus all the bailout money Bush II handed out after the 2008 financial crisis, plus the crazy spending spree Bush II let the Democratic Congress go on at the end of his term. Free resources is the root of the problem. It changes the very nature of the masses. All of that spending was dopamine, elicited in people’s brains, as well as the resultant amygdala atrophy that produces. The result is a Bonobo psychology that just emerges out of thin air.

I sometimes try to imagine how politics will look once r/K is widely known and accepted. I cannot imagine narcissistic, personal-image-obsessed liberals being able to self-identify as liberal, if that self-identification will immediately call forth all the associations with the r-strategy, from weakness and inability, to cowardice and degeneracy, to the lowly rabbit’s status in nature as a helpless prey species. Even more amazing will be watching how they handle the inevitable associations with the decline and degeneracy produced by an inherently hedonistic psychology incapable of sacrifice in the short term, to produce lasting greatness in the long term. It is even a logical explanation for why every society which trends toward r inevitably trends toward degeneracy and collapse.

Combined with the practical realization of the very real harm which arises from free resource availability and national debt spending, I cannot imagine the left will survive in anything like its current form.
