Ancestry and identity in Bronze Age Catacomb culture burials: A meta-tale of graves, skeletons, and DNA

Abstract

After discovering the first kurgans in the steppes, the archaeologists were faced with the need to determine the social status of buried persons and the relationship between people buried within the same necropolis. Archaeology has developed its methods and criteria for assessing the social status of buried persons, such as the size of the burial kurgans, the location of burials in the center or on the periphery of the kurgan, the wealth of implements, etc. With the introduction of paleogenetic methods into archeology, new opportunities for research in this direction are opening up. The analysis of ancient DNA is a tool that allows you not to assume but to establish consanguinity.This study presents the archaeological and molecular analysis of human remains from the East-Manych variant of the Catacomb culture. Catacomb culture dominated eastern Ukraine and southern Russia in the 3rd millennium BCE. The skeletons were recovered from kurgans of the Ergeninskii kurgan group in Kalmykia (Russia) that were radiocarbon dated the Bronze Age (25th–23rd century BCE). Y-chromosome STR analysis revealed that both individuals belonged to haplogroup R1b. This paternal lineage appears at high frequency in central, western, and northern Europe, and commonly appears among the Yamnaya. Analysis of mitochondrial DNA variation revealed the Catacomb males to belong to haplogroups H and N, respectively, both of which also appeared in the Yamnaya. These genetic data suggest a possible relationship between the Catacomb and Yamnaya cultures and contribute to our understanding of the cultural and historical processes occurring in the steppes of Eastern Europe during the Bronze Age.
