I find it incredible that their drifting sent them in the same general direction that Thor Heyerdahl [0] suspected (and verified in the Kon-Tiki expedition) that one would go without any extra power of their own.

The fact that a man who didn't even plan for the trip (or have any provisions) made it out alive even though he was virtually alone for the entire trip (his partner died after 2 months) leads me to believe that Thor was mostly right, and that South Americans did indeed travel to Polynesia and beyond probably more often than we originally thought.

What an amazing story.

You have it backwards. Polynesians travelled to South America and back, acquiring sweet potatoes there, possibly some human DNA, and leaving chickens (there is good evidence for each of these, but it's not undeniable). There is a huge amount of evidence of Polynesians travelling long distances by sea, and, as far as I can see, essentially no evidence for South Americans doing this. The fact that it was theoretically possible does not mean it happened.

Last year at the local planetarium I saw a great presentation about how the Polynesians navigated using the stars. It was a tradition that was almost lost, but they found someone in the 70s whose grandfather had taught him how, and now they have a school in Hawaii that teaches it.

Interestingly, part of their motivation in reviving it was that they were offended by Heyerdahl's hypothesis, which in their view basically said "Polynesians were dumb enough to get on a raft and just let it drift." More recently DNA analysis has shown that Polynesians came from Asia, not South America.
