Why does humanity have less genetic diversity than any other mammal that’s not critically endangered?
Probably because of some event in the past that few individuals survived, so that all humans since have been descended from them. Homo Sapiens is a relatively recent species and genetic diversification takes time, so the genetic narrowing effects of such population reduction would still be felt today.
But it has nothing to do with character or temperament, and as far as I know there’s no evidence Homo Sapiens actively killed off its close relatives. For whatever reason they died off, while at some point we almost did too, but we just scraped through with less diverse genes as a result. That’s how it goes in evolution: tiny differences can sometimes be amplified due to environment and chance. It’s absurd to draw political conclusions, and to do so shows a misunderstanding of evolutionary processes and history.
The system responsible for “love” and in group bonding also causes out group bias.
And in/out group is just based on who you’re socialized around as a very young child.
Overall, our findings suggest a pivotal role of the oxytocinergic system in the RIBE-modulated neural activities and revenge intention in human interactions with the modulatory effect of interpersonal trust
Oxytocin, he wrote, “motivates in-group favoritism” and “derogation” of outsiders. According to the study, oxytocin had “a role in the emergence of intergroup conflict and violence.”
According to a Vice report published this week, the study’s participants — all Dutch males — were told that they had to choose five persons out of six that would gain access to a life-saving lifeboat.
The men on oxytocin were more likely to deny men with Muslim or German-sounding names access and save the men with Dutch names, while the men who were given a placebo didn’t pay attention to the origin of the names.
Oxytocin is incredibly important. It’s why we stick around with mates and raise children, it’s why we live in groups instead of solitary. And it is directly tied (especially to men) to bias and aggression to outgroup individuals (especially other men).
Which is literally what fascism is. It’s an institutionalized bias against “them” which uses fear and violence to control everyone.
Just because you can’t immediately see the connection doesn’t mean it’s not there.
But out group bias, whether by chance or because it’s beneficial, has always existed in modern humans. It’s tied to such a fundamental neurotransmitter that it couldn’t have made a sudden change, and again, humans are essentially unchanged for 300k years.
The problem like I said in the beginning, is that after a couple centuries of civilization socializing humans, humans start thinking that socialization isn’t important and any random human can just magically grow up into a well adjusted person.

It takes fucking work
