The main goal of the project is to find and confirm DNA signatures of ancestors. French Polynesia is divided into five groups of islands: the Society Islands archipelago, composed of the Windward Islands and the Leeward Islands; the Tuamotu Archipelago; the Gambier Islands; the Marquesas Islands; and the Austral Islands. Among its 118 islands and atolls, 67 are inhabited. Tahiti, which is located within the Society Islands, is the most populous island, having close to 69% of the population of French Polynesia as of 2017. Papeete, located on Tahiti, is the capital. Although not an integral part of its territory, Clipperton Island was administered by French Polynesia until 2007.
