Modern genomes contain the accumulated history of all the migrations, splits, and admixture events that have occurred since the founding period, and teasing apart these layers of history is a complex computational challenge.

But as more modern Indigenous genomes are analyzed and as the computational methods improve, the signal of deep founding diversity — including signals that may reflect the Ancient Beringian contribution to modern populations — becomes more accessible.

Some researchers have proposed, based on analysis of modern genomes, that the signal of Ancient Beringian ancestry may be detectable in certain modern populations — particularly in some Indigenous Alaskan communities, where the possibility of a geographic continuity between the Ancient Beringian region and later Athabascan communities has been suggested.

These findings are preliminary and have not been universally accepted, but they raise the possibility that the Ancient Beringian lineage was not entirely replaced or absorbed but may have contributed a genetic component to some populations that persist to the present.
