Dynamic changes in genomic and social structures in third millennium BCE central Europe

Europe’s prehistory oversaw dynamic and complex interactions of diverse societies, hitherto unexplored at detailed regional scales. Studying 271 human genomes dated ~4900 to 1600 BCE from the European heartland, Bohemia, we reveal unprecedented genetic changes and social processes. Major migrations preceded the arrival of “steppe” ancestry, and at ~2800 BCE, three genetically and culturally differentiated groups coexisted. Corded Ware appeared by 2900 BCE, were initially genetically diverse, did not derive all steppe ancestry from known Yamnaya, and assimilated females of diverse backgrounds. Both Corded Ware and Bell Beaker groups underwent dynamic changes, involving sharp reductions and complete replacements of Y-chromosomal diversity at ~2600 and ~2400 BCE, respectively, the latter accompanied by increased Neolithic-like ancestry. The Bronze Age saw new social organization emerge amid a ≥40% population turnover.Peer reviewe

Nová stříbrná kaptorga ze středních Čech v souvislosti s konkrétním výrobním okruhem(?) v Praze

In response to the new find of a small silver trapezoid casket — i.e. kaptorga — from the grave of female H 2103 from Hostivice-Palouky, we focused our paper on the small group of such amulet caskets from Central Bohemia, decorated with engraved animal motifs on a punched background and with a knot made with the assistance of a pair of compasses on their lids and dated to the 2nd half of the 10th century. The kaptorga from Hostivice belongs to the Bohemian openable construction type IA, and was decorated with an engraving of a pair of birds with their heads turned on eitherr side of a stylized tree of life with leaf-shaped tendrils. Most of the finds from Hostivice, Klecany II, Praha-Lumbe Garden were produced in Prague during the 2nd half of the 10th century
