How do you define races? As I said in another comment definitions shift and they are different in different countries. I have an encyclopedia from the 1950s that defines South Asians as "Caucasoid". Some East Africans were also defined as "Caucasoid" historically.If we define races on the basis of genetic similarity then almost everyone whose ancestry is from Eurasia is the same "race", but people whose ancestry is African belong to multiple races.
Race was only ever a stand in before we had an accurate understanding of genetics.
It's a bit like the old adage that we should not judge a book by its cover. The outside often does not provide any clues into the content or worse, it could bias an observer's opinions about what they would find inside if they chose to engage with the material.
Its akin to judging a man by the color of his skin instead of by the content of his character.
Thanks for your comment that clarifies how genetics provides a much more granular window into an individual than any physical characteristic taken by itself can provide.
