Each new specimen with recoverable genomic data from the early Alaskan record is potentially significant.

If the Ancient Beringian branch was genuinely distinct from Northern Native Americans by 11,500 years (USR1), and if it persisted in western Alaska to at least 9,000 years (Trail Creek), then specimens from intermediate periods and from other geographic locations could help trace the specific demographic history of this founding lineage with greater precision.

Specimens from the Alaskan interior from the 9,000–11,000-year period could help determine whether Ancient Beringian ancestry was widespread across Alaska at this time or whether it was already concentrated in specific geographic regions.

Specimens from the Seward Peninsula from later periods — if any such specimens exist — could determine when and under what circumstances Ancient Beringian ancestry appears to have been diluted or replaced.
