Introduction

The presence of bananas in Rapa Nui (Easter Island) is a botanical anomaly that provides a critical clue to ancient Pacific contact. This investigation tracks the genetic lineage of these plants to determine if they were brought by early Polynesian voyagers from the west. The introduction of non-native species reveals the seafaring reach and agricultural strategies of the island's builders.
