Which ethnic group has natural "female" eyebrows?

[Pantisocrat]

Women seem to spend a ton of time to get their eyebrows waxed to the "standard shape" beauticians define for them, which is a central broad end streamline to a narrow tip at the opposite ends. Which ethnic group of women actually has natural eyebrows that look like this standard? It seems to me that white women tend to have a straight line for brows, while semitic women a bushy unibrow, and Asian women a very broad brow at the edge. Black women's natural eyebrows tend to be closer to this standard but then their hair seem to be an outlier...kinda confused.

This is what I mean by standard:

I have seen many Western Euros, specifically Italian, Spanish and Franch women with this eye brow shape naturally.

My sister and myself have naturally arched eyebrows. We're a mix of scots-irish and African-american.

I have naturally arched and shaped eyebrows. Scotch-Irish and Spanish right here.
