Polynesian archeology carbon dating

13, well after Polynesians first settled Easter Island and the other easternmost islands of the Pacific.

This is consistent with the stages of cautious Pacific exploration: first the Kermadecs, then New Zealand (possibly including as far south as Enderby Island in the subantarctic Auckland Islands), then the Chathams.

An analysis of Polynesian migrations based on the archaeological assessments by Yosihiko H.

The Kermadec group and Norfolk Island lie about halfway between East Polynesia and New Zealand, and it is likely that Polynesian explorers returning from New Zealand stopped at these islands on the way.

Distinctive New Zealand obsidian, a glassy volcanic rock used for cutting, is found in archaeological sites on the Kermadecs, and may have been carried there by returning voyagers.

A more recent study published in the July 2008 Proceedings of the National Academy of Sciences and based on testing a larger number of chicken bones concluded that the DNA matched that of European chickens and that contamination resulted in the radiocarbon date appearing to be older than it actually was.

Polynesian Chicken Bone • El Arenal, Chile DNA analysis of a chicken bone from a prehistoric site in Chile shows Polynesian seafarers first brought the birds to the New World.

In East Polynesia, the history of human occupation goes back approximately 2,000 years, as far as we know today.

The Marquesas Islands have produced the earliest radiocarbon dates, along with material assemblages, for establishment of a comparatively solid cultural sequence from the time of settlement to the historic period.

Ash that has erupted from volcanoes, consisting of volcanic glass, rock fragments and mineral grains, has a distinct chemical makeup.

This means it can be analysed to identify and date when eruptions occurred.

This settlement must have occurred after that eruption.
