A view of the excavation site at an Avar cemetery in Rákóczifalva, Hungary Eötvös Loránd University, Budapest Unraveling the Mysteries of the Avar Empire The Avars, originating from Central Asia, embarked on a historic migration to Eastern Europe, leaving an indelible mark on the region's history. Rácz, Z.,
Introduction A new study, recently released as a preprint on bioRxiv , sharpens the timeline for this crucial period in human history. For instance, ancient individuals from Oase and Bacho Kiro showed very recent Neanderthal ancestry, suggesting frequent interactions with Neanderthals, even if their lineages did not persist.
Colors indicate genetic ancestry, and black crosses designate individuals with the plague.Credit: Seersholm et al., Nature (2024) Waves of Plague The new study suggests that Scandinavia experienced three distinguishable waves of plague during the Neolithic period, spanning about 120 years. 1 Seersholm, F. Sjögren, K.-G.,
