Yeah it is an attempt to correlate genes to geography with far more precision than actually existed and assumptions that populations were hermetically sealed when they weren't. Regional classifications are often even worse in GIGO associations from what I heard with trying to distinguish between say Dutch, Polish, German, and Swiss. It brings to mind sarcastically asking questions about connections to long gone civilizations that nobody really identifies as. How many people globally are Scythian? Babylonian? Carthaginian? Sumerian? Minioan?

It brings to mind the 'smartass genie' technically most accurate way of classifying blackness by just including a count of melanin producing genes.
