Major take-home points:
1. It is remarkable how European genetic variation mirrors geography (a la Novembre); one can discern the crude outlines of the European continent from European samples of the PCA plot. This (again) suggests that intra-European genetic variation is most clinal and heavily shaped by geographic factors and those population processes affected by geography. If Der Movement’s fantasies were instead correct, one would see a sharp discordance between the plot locations of (some of) the samples and the geographical association
2. Jews and some Turks (presumably the more “Europid” of these) are located in between the southernmost extreme of Europe’s genetic variation and samples from the Middle/Near East. This is consistent with Jews being a mix of Middle/Near Eastern and predominantly (Southern European) European ancestry, and with a common Neolithic major component between Southern Europe and Anatolia, as well as the fact that some Turks are heavily admixed with European ancestry (e.g., Greek/Balkan).
3. The wonderfully “Aryan” Iranians are genetically distinct from all types of European stocks.
Of course, in the end, regarding biopolitics, what matters is genetic kinship, which should be assayed directly; nevertheless, these data can be of some racial-historical interest.
