Ancient genomics of Neolithic to Bronze Age Baikal hunter-gatherers


Genome-wide data from hunter-gatherer populations of the Upper Paleolithic to Neolithic has provided unprecedented insight into the human evolutionary and demographic trajectory. However such datasets have hitherto been largely confined to Western Eurasia. The sole representative of Inner Asian past populations post-dating the split between paleolithic Europeans and Asians, as well as paleolithic Siberians and East Asians, are the Mal'ta and Afontova Gora individuals, the Ancient North East Asian (ANE) branch, clouding the dating of the population split, and subsequent admixture events, between ANE and East Asian hunter-gatherers. Our genome data (~1X) reveal that Baikal Hunter-Gatherers (BHG) are an uncharacterized genetically homogeneous branch of Inner Asian hunter-gatherers, displaying highest shared genetic drift with present-day East Asians. Targeted sampling strategies coupled to excellent biomolecule preservation has permitted the generation of an advantageous sample size dataset (n=31), rendering possible to estimate allele frequencies within these groups, thereby optimizing population tests. BHG model as an excellent proxy for an Inner Asian source population admixing into the late Bronze Age Andronovo groups, becoming Iron Age steppe nomads. With genomes allowing for kinship analyses, pathogen detection and strontium ratios, coupled to archaeological interpretative approaches we extend possible means to elucidate behavioral processes and cultural transformation.
