Genetically, Sunghir 1 was a classic cro-magnon belonging to the basal West Eurasian core population of hunter gatherers who lived approximately 34,000 years ago. He is closely aligned with the Vestonice and Kostenki genetic clusters, and carried the rare paternal Y-DNA haplogroup C1a2, which is an extremely rare haplogroup that is actually found in modern humans (cro-magnons), and also had roughly 2.5% to 3% Neanderthal ancestry. Interestingly, he was not entirely isolated from the east, carrying around 2% of Tianyuan related (East Eurasian) gene flow. He is a direct Pre-WHG lineage to Western Hunter-Gatherers and provided the ~71% West Eurasian genetic foundation that later migrated east to form the Ancient North Eurasians (ANE).
