Jon Erlandson Widespread Quotations

The coastal migration theory has yet to be proven with hard evidence, but we have been finding earlier and more widespread evidence for coastal settlement around the Pacific Rim. The fact that productive kelp forests are found adjacent to some of the earliest coastal archaeological sites in the Americas supports the idea that such forests may have facilitated human coastal migrations around the Pacific Rim near the end of the last glacial period. In essence, they may have acted as a sort of kelp highway.
