There's studies on mammal populations, and as their preferred number of group sizes increases, the 'differentiable' traits also increased. So mammals that preferred to live in large groups had more visible differences in phenotypes than small groups.
If social systems are just an extension of phenotypes to some degree, then all that's really happening is people wanting to differentiate and they have a small differentiable desire in any given direction.
but you be you.

Books don't change. The online written word is subject to revision and change, as are ebooks. A physical volume which one owns and holds cannot be memory-holed.
