The people who lived in Polynesia hundreds of years ago were known for their voyaging capability. They practiced wayfinding, or navigating, by using careful observations of the natural world including the stars, the Sun, and ocean waves. We know they sailed between clusters of islands that includes Marquesas, Mangareva, and Rapa Nui using their sturdy double-hulled canoes, but did they travel all the way to South America? Until recently, the strongest evidence to answer this question was the presence of the sweet potato, a crop native to South America, in Polynesia. However, recent research analyzing human DNA from Polynesians and South and Central American groups sheds new light on the mystery.

The Smithsonian is an institution dedicated to the public good, and in these times, we take that mission more seriously than ever. Although most of our museums and research centers are temporarily closed, we remain hard at work—educating, inspiring and supporting Americans through this difficult period.

During the past few months, the country has grappled with dual pandemics—the first a pandemic of illness, the second a pandemic of racism. It is like no other moment in American history.

People everywhere are turning to the Smithsonian in record numbers for context and knowledge. By making the wonders of science, art, history and culture accessible to all, we help the public understand the complexities of our world and feel part of a shared human experience.
