This narrative has been applied to various early American sites and various anomalous-seeming early American skull morphologies, and it has been used to suggest that current Native peoples are not the original inhabitants of the hemisphere in the relevant sense.

The USR1 genome does not support this narrative.

It refutes it.

The Ancient Beringians were part of the founding population of the Americas.

The founding population of the Americas is the ancestor of all sampled Native American populations.

The diversity within that founding population — the branching structure, the early divergences — reflects the natural processes of population differentiation that occur in any large, geographically spread population over thousands of years.

It does not reflect the replacement of one people by another.
