To me this is interesting because it may further my nagging suspicion I had for quite some time (this is not my field of expertise). The Americas were discovered multiple times, from multiple direction, by multiple people. What order they were is only my vague guess except for the last one. Today children are taught that the Americas was settled by people crossing the frozen Bering Sea. But, this discovery further discredits this simplistic hypothesis. I think the Americas were settled numerous times from the Pacific Rim through boats, the Bering crossing on foot, and through more boats reasonably West Africa, and Northern Europe - all prior to Cristoforo Colombo.
