The first proven inhabitants were the Arawaks, though there may have been other native peoples prior to this. The Arawak are believed to have come from northern South America sometime around AD 200–400, as there are numerous archaeological sites on the island where specimens of their well-developed pottery have been found. There is evidence to suggest that the Arawak called the island ''Iouanalao'', meaning 'Land of the Iguanas', due to the island's high number of iguanas.
