Pre-Columbian Contact Theories

Why Ancient Inquiry uses this citation here

Peer-reviewed PNAS plant-genetics study supporting a pre-European sweet-potato introduction to Oceania while leaving the human route and direction of movement unresolved.

What this usage does not establish

Bibliographic verification does not by itself establish that the full text was read.

Pre-Columbian Contact Theories

Open topic
Supporting citation for public claim

Pre-Columbian contact must be evaluated claim by claim: dated archaeological context establishes Norse presence, while genomic and crop evidence support bounded Pacific contact questions.

The dossier treats this as an open source and evidence question.
Open claim topic
Limiting / critical citation for public claim

Specific Norse and Polynesian-Indigenous American contacts are evidenced, but those cases do not show that numerous outsiders founded or directed Indigenous American civilizations.

The evidence does not automatically support broader causal, technological, transmission, or literalizing claims beyond the cited record.
