Which islands visited rafts Tupac Yupanqui? if they got to the Melanesia is indeed populated by black people? Or, according to Heyerdahl, "black" it is to be found among the inhabitants of Mangareva island, since "discovered the island Beachy found among extremely variegated composition of the population of people with the same dark skin, like the Melanesians"? Or the story of the journey of Tupac Yupanqui at all an invention (in fact in the legend states that the expedition brought a bronze throne, jaw horses and a lot of gold - yet none of the islands of Oceania no bronze, or gold, or, especially, horses )? There's also posing the question: whether the legendary island disappeared (such as "Fire Island"), which narrate the Indian tradition, in the ocean? Perhaps the way the Mariners on rafts facilitated intermediate "milestones", islets and islands, lying on the route from South America to Polynesia? These Oceanography say that such islands and islets, indeed, raised once from the depths of the ocean.
