Situated on the western bank of the Yenisei River near Krasnoyarsk, Afontova Gora is an immense, multi-layered Upper Paleolithic site complex that has permanently transformed the science of global human paleogenomics. Excavated extensively across the 20th and 21st centuries, the site preserves a continuous sequence of human occupation dating from 15,000 to 21,000 years ago, right on the cusp of the final retreat of the Ice Age.
The successful extraction of high-quality nuclear DNA from a human fossil at the site—cataloged as Afontova Gora 2 (AG2)—provided the critical missing link to solving the historical puzzle of the settlement of the Americas.
The Genomic Extraction: Unveiling ANE
The paleogenomic analysis of the Afontova Gora 2 individual—an adult male who lived roughly 17,000 years ago—was conducted using high-throughput shotgun sequencing of ancient DNA isolated from a tooth root. The data confirmed that AG2 belonged to a distinct, highly unique genetic lineage designated by paleogeneticists as Ancient North Eurasians (ANE).
The ANE lineage, as defined by Afontova Gora and its older relative Mal'ta 1, represents a ghost population that once occupied vast swaths of Siberia but has no pure, un-admixed living descendants today.
Genetically, these people were deeply distinct from modern East Asians; instead, they shared a close, deep-time common ancestry with Upper Paleolithic Western Europeans, explaining why early anthropologists were frequently confused by the rugged cranial morphology of Siberian skeletons.
The Missing American Link
The ultimate scientific paradigm shift occurred when geneticists compared the Afontova Gora 2 genome directly to the DNA of ancient and living Indigenous Native Americans:

[ INDIGENOUS REVELATION ] ───────────► 14% to 38% Direct ANE Genetic Inheritance
The data proved that Native Americans are not descended from a single, simple migration of East Asians across the Bering Land Bridge. Rather, they are the result of a profound, ancient admixture event that occurred within the geographic crucible of Beringia.
Between 14% and 38% of the entire nuclear genome of all Indigenous Native Americans is derived directly from the ANE population preserved at Afontova Gora.
This explains why modern Native Americans share direct genetic markers with both Western Eurasians and East Asians. Afontova Gora stands as an irreplaceable biological monument, documenting the exact Siberian population that braved the cold expanses of the Yenisei River basin before their genes crossed the world's northernmost horizons to populate an entirely new hemisphere.
