Comment on Dogs may have domesticated themselves because they really liked snacks, model suggests

Every species can domestic themselves, even humans did it.
We show every charistic of it, even if people don’t like talking about it.

Even Silverbacks, long thought to be the proverbial “alpha males” don’t force females into their harems and recent research have shown that the Silverback they choose to follow is often the most compassionate one rather than just the biggest and strongest.
They’re just all fucking huge, so it’s really not that important if one is slightly bigger.

That article doesn’t mention it, but more prevalent Neoteny is likely another thing caused by humans domesticsting themselves.

When people look back at films of the public from 100 years ago and notice that men in general seem to be less baby faced and have sharper features… they’re not wrong.
More and more adult women have pelvises and birth canals incapable of safely delivering a baby without a C Section.

More so because everyone was a raging alcoholic that spent their time outside and sunscreen hadn’t been invented yet…
Even the argument that an older father results in longer telemeres in a child and a longer time till aging sets in…
Old guys were marrying very young girls 100 years ago too.
True, but that’s the same reason we started to de-volve the appendix and then stopped: advancement of modern medical treatment.
An insane amount of women used to die in childbirth, while other cranked out 15 kids from the time they were 14 till they were 30.
Wanna guess if there was a correlation in hip size?
We don’t have that evolutionary pressure anymore, so women with narrow hips can have just as many kids as women with wide hips.
When you remove evolutionary pressure, things that used to be selected against start becoming prevelant again.

Yes. That … is part of domestication.
When a relatively self sustaining, organized society assembles itself, becomes more sedentary and less mobile, ie, domesticates itself, evolutionary selection pressures shift.
With humans, this is vastly exagerated and complexified due to our societies developing technology.
C Sections become prevalent, evolutionary pressure against a neotenous trait (adult females having narrow birth canals) lessens, thus the trait becomes more common.
The exact science on what leads to ‘baby faces’ is extremely complex, but it certainly seems safe to say that body fat levels, obesity levels, have risen, and that a lot of that can be linked to endocrine systems being altered/disrupted by our technologically mass produced food, leading to higher rates of neotenous features in adults.
Domestication is a prerequisite for human civilization, which is seemingly a prerequisite for most of our advanced technology, said technology then intensifies neoteny.

Neoteny is 100% a thing and relevant to domestication…
But that’s more because childhood is a very very expensive thing biologically that is punished harshly in most environments, but pays off dividends in adulthood.
At a certain point, it’s best to never grow out of those conditions.
You’re still viewing it thru the lens of human civilization
