I mean people won't like the idea but that's not my point; what you describe variety in superficial traits while maintaining common traits

Applied to humans; skin color, eyes, dwarfism, hypertrichosis... can still interbreed

When it comes to categorization and taxonomy in leaky abstractions like languages the boundaries get a bit hand wavy and usually land on whatever fits the prevailing social desirability bias of the day

The same selection pressures that produced the variety of "superficial" traits also act on "non-superficial" traits - nature does not recognize this distinction.

You cherry picked one idea from my post. I was not addressing nature but human social tropes.

What is a subspecies and species is random gibberish of the living humans
