Deceptive title. The science around this issue was settled definitively in 1976 and multiple lines of evidence have only strengthened the story since then. It's no longer even remotely mysterious: People built boats and sailed eastward from Asia and navigated without instruments. Thor Heyerdahl was wrong and Captain Cook was right.

Discussed here a few days earlier:

The Voyage of the Kon-Tiki Misled the World About Navigating the Pacific (2014) (smithsonianmag.com)

The full title is Pathway of the Birds: The Voyaging Achievements of Māori and their Polynesian Ancestors. The book shows - among other things - how tens of millions of shearwaters on migration to their nesting sites in spring point to the whereabouts of islands.

It was shocking to learn Guam was settled 4,000 years ago by the Chamorro people who built boats and seemingly sailed 2,000+ miles from Southeast Asia.

That really is misleading. Ok, we changed the title above to that of the book being reviewed.

That 2014 article is much better. Interesting that it was discussed here so recently (as vram22 points out).

And presumably if there remains any debate about this we could settle it with a genomic study.

Wouldn't be surprised if Cavalli-Sforza had done it already.

Genomic studies suggest that the ancestor of the Polynesian people were from a combination of New Guinea and ancient Taiwan.
