Last week, we released our preprint on Poseidon, which seeks to make archaeogenetic data more Findable, Accessible, Interoperable and Reproducible, by defining a data package standard, software tools and public repositories and cloud infrastructure 1/12

Great news! 🥳 Led by the amazing Mateja Hajdinjak, a new Max Planck Research Group for Hominin Palaeogenomics started MPI-EVA Leipzig. 😊😍 Using cutting-edge #aDNA methods, its goal is to shed light on past encounters between hominin groups. Max Planck Society eva.mpg.de/press/news/art…

Yesterday, we published our paper on genetic analyses of early Celtic princely burials from Southwestern Germany today. An important piece of @JoGretzing’s award-winning PhD thesis, we explore kinship and ancestry from the late Hallstatt-Culture. 1/10

This is now published in Scientific Data: nature.com/articles/s4159…. The survey is expanded to 42 studies, and the paper now includes a Box 1: "Step-by-step best practices for archiving ancient genomics data in the European Nucleotide Archive (ENA)." I hope this will prove useful!

Very happy to share the results of my Marie Skłodowska-Curie Actions project done at UCL Genetics Institute with Mark Thomas and Pontus Skoglund from The Francis Crick Institute. We used ancient DNA to reveal remarkably high genetic diversity in the region of modern-day Ukraine / Україна over the last 3,500 years until ~500 years ago.

The study was made possible by the resilience of Ukrainian researchers – second author Olga Utevska from V. N. Karazin Kharkiv National University and MSCA4Ukraine fellow at genomicstartu, and numerous archaeologists conducting excavations in Ukraine despite the war.

The North Pontic region, which encompasses present-day Ukraine, was for centuries a crossroads of migration from multiple directions, connecting the vast Eurasian Steppe with Central Europe.

The analyses show that broad-scale ancestry proportions characteristic of present-day European populations have been present in the Ukraine region since the Bronze Age until today.

However, from the Early Iron Age until the Middle Ages, the appearance of eastern nomads in the region became a regular occurrence. Their genetic composition varied from steppe ancestry mixed with the local background to mostly East Asian ancestry with minimal local intermixing.

At the same time, the rest of modern-day Ukraine was inhabited by people with both local Eastern European and Western and Southern European genetic heritage. These diverse origins can be linked to migrations and connections found in archaeological and/or historical records.

Migration and population mixing will have contributed to the high genetic diversity in geographically, culturally and socially homogeneous groups, with different genetic profiles present at the same site, the same time and among individuals with the same archaeological context.
