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.
