The picture of American genomic history in this period is less complete than the picture for early founding events.

What the Hoyo Negro findings contribute, within these acknowledged limits, is a specifically American founding lineage that was already present in Mesoamerica more than twelve thousand years ago.

Naia was here.

Her maternal line was part of the American founding.

Whatever specific processes of migration, mixing, and change led from her to the Maya and their neighbors, those processes unfolded within a founding lineage that was already established in the region.

This is not a trivial finding, even if it is a limited one.
