Thanks-what little I’ve read of their origins and other Polynesians don’t indicate a pure ethnic group, either-it talks about people from Australia, Aryans from what is now India, and parts of Asia-all getting into boats and island hopping for centuries-very interesting people, but not ethnically pure, like Obama is wishing-some anthropologists say DNA tests show only 50% of Hawaiians who call themselves natives really are.
The privately owned island of Niihau in the Hawaiian chain is home to these natives, & is closed to outsiders.
Most native-born Hawaiians who don't claim racial "purity" are proud of their unusual mixed genetic histories.
