The attempt to connect ancient archaeological evidence to specific modern tribal identities is a recurring source of tension in American archaeology, and for good reasons.

The temporal distance between 14,000-year-old evidence and any modern community is enormous — enormous enough for populations to move, languages to change, cultural traditions to transform, and biological ancestry to be diluted through admixture with other groups.

Drawing straight lines from ancient coprolites to modern tribal identities requires much more evidence than the Paisley site alone provides.

This does not mean that the Paisley evidence is irrelevant to Indigenous peoples and their histories.

It is deeply relevant.
