> Not very surprising that the official US races are BS.
The modern concept of "race" in general is a BS construct that was invented to support and justify European imperialism, and which has long been recognized as having only the loosest relation to biological reality despite in its own terms being conceptualized as a biological reality of some importance.
OTOH, its also produced very real communities of differentiated experience, identity, and treatment, and it is largely that which the US government system of race (plus one ethnicity, in the minimum scheme) is designed to gather data related to.

"Caucasian" is not part of the official race/ethnicity scheme used in US federal government reporting. Someone who has prehistoric ancestors who were from the region which is now Portugal or France, and who identifies with the racial group into which people with that ancestry are categorized, would be White, possibly with another racial and/or ethnic category depending on what other ancestry they identified with.
> whereas someone from Spain is supposed to be Hispanic
With the same description as above, replacing "Portugal or France" with "Spain", the person would still be White.
A person who also identifies with Spanish or South, Central, or North American (south of the US border) national/cultural origin would be Hispanic or Latino by ethnicity (the only ethnic category in the scheme) as well as any racial category or categories they identify with.
Here's a news release on 2024 updates to the scheme, which involve combine the race/ethnicity questions into a single multiple answer allowed question (the race question was already multiple answers allowed, but the presence or absence of the one ethnic category was a separate question) as well as other updates to the scheme: https://www.census.gov/newsroom/blogs/random-samplings/2024/...
Regardless of what specific term is used, it is used (and abused!) equivalently pretty much everywhere humans exist.
Is ‘caste’, race? Because it sure is used that way (or worse) in places that have it. And that’s been going on for longer than what we currently call European civilization.
Caste is synonymous with social class. There is no genetic or racial component to it, and no one is claiming as such (including the people who are discriminating on the basis of caste).
The study shows the reverse effect. Because of the emergence of the caste system and rigid classes people stopped intermixing across caste boundaries and now 2000 years later you can find certain genetic differentiators between them.
The reality is the same for "Race" and "Ethnicity", and all sorts of other words that humans have used to categorize "not my family".
French colonists to the new world freely intermarried (and had kids) with Native Americans and people brought over from Africa, and eventually those same groups were prevented from marrying under racist american laws.
So there's lots of french blood in black people in the southern united states, but they were eventually prevented from marrying white french people, even when they were literally part of the same large family tree! There are long lines and families of black people who literally descend from my ancestors that I wouldn't have been allowed to marry!
Which should clearly demonstrate that it was never about your genetic or biologic ancestry, as modern science knows.
Wikipedia claims America's "blacks can't marry whites" laws have no precedent.
Similarly, there was lots of inter-racial relations before some colonies banned it, and other colonies never banned it.
