Project description:The whole genomes of four ancient Irish individuals reveal large scale population migration to have played a key role in the Neolithic and Bronze Age transitions in the British Isles.
Project description:Protein analysis of Bronze Age Cauldron residues. Found blood from ruminant caprines, and milk proteins from bovids, including yak (Bos mutus).
Project description:Gendered burial practices that differentiate between men and women by the way the body was placed were used over large parts of Central Europe in the Late Neolithic and Early Bronze Age (c. 2900−1600 BC). The differentiation of bodies placed on the left/right side in opposite orientation was extended to children, but until recently, it was difficult to confirm if the biological sex of the children matched the classification as men and women. We applied nanoflow liquid chromatography-tandem mass spectrometry (nanoLC-MS/MS) to identify sex-specific peptides in human tooth enamel in 75 children buried at one of the largest Early Bronze Age cemeteries in Europe, Franzhausen I, Austria, 70 of which produced reliable results. The study confirmed that the sex of the children corresponds to the gendered body position in 98.4 % of cases. For burials in which the gendered sidedness and orientation are not internally consistent with the male or female pattern, we found that the sidedness of the body corresponds to the sex of the children rather than the orientation.
Project description:Ancient DNA studies have revealed how human migrations from the Neolithic to the Bronze Age transformed the social and genetic structure of European societies. Present-day Croatia lies at the heart of ancient migration routes through Europe, yet our knowledge about social and genetic processes here remains sparse. To shed light on these questions, we report new whole-genome data for 28 individuals dated to between ~ 4700 BCE-400 CE from two sites in present-day eastern Croatia. In the Middle Neolithic we evidence first cousin mating practices and strong genetic continuity from the Early Neolithic. In the Middle Bronze Age community that we studied, we find multiple closely related males suggesting a patrilocal social organisation. We also find in that community an unexpected genetic ancestry profile distinct from individuals found at contemporaneous sites in the region, due to the addition of hunter-gatherer-related ancestry. These findings support archaeological evidence for contacts with communities further north in the Carpathian Basin. Finally, an individual dated to Roman times exhibits an ancestry profile that is broadly present in the region today, adding an important data point to the substantial shift in ancestry that occurred in the region between the Bronze Age and today.
