The 31,000-Year-Old Children’s Teeth Found Above The Arctic Circle — And The DNA Test That Revealed A Lost Ice Age Population Connected To Native American Origins
This is speculative.
The evidence does not yet exist to confirm or deny it.
What the evidence does show is that ANS ancestry was present in northeastern Siberia 31,000 years ago and that a diluted form of that ancestry was present 10,000 years ago.
What happened in between is a twenty-thousand-year gap in the ancient DNA record of a region that is the size of a continent.
Filling that gap will require finding more ancient human specimens from the region — a challenging task in a landscape where human occupation was sparse, where preservation is dependent on permafrost conditions that vary across the region, and where the archaeological infrastructure is limited by the remoteness and difficulty of the terrain.
