The landscape of her daily experience was shaped by the sea in ways that the landscape of the Ancient Beringian world before her birth had not been.
This geographic context — the post-land-bridge Seward Peninsula — is relevant to understanding what the persistence of Ancient Beringian ancestry at 9,000 years might mean.
People living on the Seward Peninsula after the submergence of the land bridge were geographically bounded in ways they had not been before.
The broad Beringian world that their ancestors had ranged across was now partly underwater.
The routes that had connected Beringia to the interior of the Americas — through the ice-free corridor or along the Pacific coast — were still available but required moving south, away from the coastal and maritime environment that the western Alaska coast provided.
