➀The dating of the White Sands footprints over the past five years has yielded a median age of 22,000 BP. The multipurpose use of nine types of seaweed and knotted ropes at Monte Verde in Chile indicates a maritime culture, strengthening the coastal route hypothesis for the western side of the New World. Furthermore, the DNA affinity with Population-Y, the first wave in South America, suggests connections to ancient coastal peoples of East Asia and Oceania.
➁If the Kelp Highway route is accepted, the Japanese archipelago and Kuril route become significant. The Hokkaido Sojin (descendants of the Izu Sojin, who navigated for obsidian around 38,000 BP and are the pre-Jomon ancestors) are now in the spotlight.
