🐎 Avars in Austria: shared culture, separate gene pools

Seventh–eighth century cemeteries just south of Vienna split sharply by ancestry. At Leobersdorf, people carried a median ~71.5% East Asian–related ancestry that stayed near ~70% over ~150 years. Nearby Mödling remained European-like with <5% East Asian on average.

Despite living only ~20 km apart and using the same Avar-era material culture, the two communities barely intermarried; partner choice within wider Avar networks kept the divide in place, helped by female exogamy and patrilineal lineages.

Takeaway: In the late Avar period, the Vienna Basin held two parallel populations — culturally similar, but genetically distinct for generations.
