Were there other resource bases — fish, marine mammals at the coast — that other ANS communities were exploiting?

The archaeology of the broader Yana region, which is still being investigated, may eventually reveal additional sites that expand the picture of ANS subsistence.

How did the ANS interact with other populations of their time?

The 2019 study suggests relative isolation of the ANS from contemporary southern Siberian populations, but this isolation was probably not absolute.

There may have been zones of contact and exchange, periods of gene flow that the available ancient genomes are too few to detect but that future specimens might reveal.

And the deepest question: what caused the apparent decline or absorption of the ANS population?
