Abstract
This paper investigates the timing of initial human settlements and the introduction of horticulture in Remote Oceania using a sediment core from Efate, Vanuatu. Sedimentary biomarkers reveal a simultaneous increase in indicators of human presence (coprostanol and epicoprostanol) and taro cultivation (palmitone) around 2800 years ago, suggesting the early introduction of horticulture by first settlers. Leaf wax analysis indicates that this initial settlement occurred during a period of increasing wetness, favorable for horticulture. These findings refine our understanding of human history in the Pacific.
