The 2008 Paisley result arrived in a specific intellectual context that made it explosive, and that context needs to be understood to appreciate why the claim generated such intense scrutiny.

The Clovis-first model — the hypothesis that the Clovis culture represented the first human presence in the Americas, and that all Native Americans descended from a single founding Clovis-era population — had been the dominant paradigm in North American archaeology for roughly fifty years by the time the Paisley results were published.

It was not merely an academic hypothesis; it was a deeply entrenched framework that had shaped how archaeologists evaluated evidence, trained students, allocated research resources, and interpreted the significance of new findings.

Under the Clovis-first model, any site claiming to show human presence before the Clovis horizon faced an extraordinarily high evidentiary bar.
