Populations can maintain biological continuity across time while undergoing substantial cultural change.

The development of new technologies, new social forms, and new ceremonial traditions does not require biological replacement of the population that developed them.

What the genetic continuity does suggest is that the cultural developments of the Northwest Coast over the past 10,000 years were largely the achievements of the founding coastal population itself — innovations and elaborations developed by the descendants of the early maritime people, building on the foundation of maritime adaptation that their ancestors had already established by the time Shuká Káa was alive.

This reframes the Northwest Coast cultural tradition in an important way.
