While Heyerdahl proved that it was possible for native americans to cross
the pacific, there is little evidence (in the form of cultural remains)
that there was any contact between South America and Polynesia.
Genetically Indians and Polynesians are distinct also. See Cavalli-Sforza,
Menozzi and Piazzi, The History and Geography of Human Genes, (Princeton
University Press, 1994), p. 78.
Most of the traffic across the Bering Strait seemed to have been a one way
traffic, especially after the sea level rose cutting the two continents off.
