The sample size is very small: two individuals, from two different sites, separated by approximately 2,500 years and a considerable geographic distance.

Drawing strong conclusions from two data points requires appropriate caution.

But the pattern — Ancient Beringians in the Alaskan interior at 11,500 years, Ancient Beringians on the Seward Peninsula at 9,000 years — is exactly the kind of evidence that builds a foundation for more specific hypotheses about population history, hypotheses that can be tested as more ancient specimens from the region become available for analysis.
