The Icelandic sagas suggest that the Norse engaged in cultural exchanges with the Indigenous groups of North America34. If these encounters indeed occurred, they may have had inadvertent outcomes, such as pathogen transmission7, the introduction of foreign flora and fauna species, or even the exchange of human genetic information. Recent data from the Norse Greenlandic population, however, show no evidence of the last of these.
Is it possible the Vikings were not in that location long enough for populations to mix? Or they were so remote (physically, culturally, and linguistically) that limited opportunities arose? Or something else?
