The rest of the child’s story does not speak, because the evidence for it does not exist in recoverable form.

What does speak — what the tooth says that goes beyond the individual child — is what makes the Trail Creek finding genuinely significant at the level of scientific history.

The Second Ancient Beringian

To understand why the Trail Creek child’s genomic assignment mattered, it is necessary to know something about Upward Sun River — the other site where Ancient Beringian ancestry had been identified, and the context within which the Trail Creek finding was interpreted.

Upward Sun River is an archaeological site in central Alaska — not on the Seward Peninsula, not near the coast, but in the interior of the state, in a setting that reflects the inland ecology of subarctic Alaska rather than the maritime environment of the Seward Peninsula.
