Natives of Crimean 30k years ago, most similar group.. Puerto Ricans? Lol

I’m looking at a ~35,000 BP Upper Paleolithic sample from BuranKaya (Crimea), and the admixture model shows components like “Natufian,” “Sub-Saharan African,” and even “Anatolian Neolithic Farmer.” Given the very early date, I’m assuming these are just modern proxy populations being used to model deep shared Out-of-Africa ancestry rather than indicating real African or Levantine admixture in Crimea at the time. Would it be correct to interpret this as a projection artifact from using much later Holocene reference populations on a Paleolithic genome?

But it kind of brings these calculators into question, Puerto Rican lmao? Also why PR and then all of a sudden other people already close to this region genetically? Why Jomon or Melanesian, because they were somewhat still genetically similar to these people? I'm just wondering what makes it give these results, particularly since most of these groups didn't form until thousands of years later..

Notice how Roma are closer.

It is an older layer of ancestry that once existed in West Eurasia, but they likely did not leave any living descendants and were probably linked to Magdalenian-related ancestry.

In reality, that great distance indicates that although those are the closest modern populations, they actually have nothing to do with them.

A Puerto Rican is a sum of Europe+Africa+Asia, it is understandable that this mixture may be the "closest" to ancient populations of that area.
