For a direct answer to your question, the Polynesians populated much of the vast Pacific ocean and founded many island native lineages. There is some strong evidence they came into contact with West Coast American natives within the last couple thousand years [0]. > We find conclusive evidence for prehistoric contact of Polynesian individuals with Native American individuals (around AD 1200) contemporaneous with the settlement of remote Oceania. Our analyses suggest strongly that a single contact event occurred in eastern Polynesia, before the settlement of Rapa Nui, between Polynesian individuals and a Native American group most closely related to the indigenous inhabitants of present-day Colombia.
