The paper resolves the controversy with the Easter Island (Rapa Nui) population. After colonization, the population from Chile mixed with the population from Rapa Nui. This paper conclusively shows that a 1200 AD (i.e. pre-colonization) event occurred on one of the eastern Polynesian islands before Polynesians settled Easter Island. The "hub" island radiation starts in the natural east-to-west currents. The Rapa Nui admixture is from Chile but the pre-colonization admixture is from Columbia and it is found throughout eastern Polynesia along with the South American sweet potato. It is not known whether Polynesians sailed to Columbia/Ecuador and back or if South American natives sailed to Polynesia. A fisherman blown off course doesn't fit with the spread of the sweet potato and gourds, but who knows. The there-and-back-again narrative fits the Polynesian practice of exploring upwind/up-current and allowing the wind/current to help you get back. I use the same safety technique when canoeing and diving.
