Ancient Rapanui genomes reveal pre-European contact with the Americas

Ancient genomic analysis of 15 Rapanui individuals from Easter Island has provided new insights into the island's demographic history, challenging the widely accepted "ecocide" theory that suggests a severe population collapse due to resource overexploitation in the 1600s. The study found that the ancient Rapanui were Polynesian and closely related to present-day Rapanui, with no evidence of a significant population bottleneck during the proposed collapse period. Additionally, the research revealed that both ancient and modern Rapanui carry approximately 10% Native American genetic admixture, indicating pre-European contact between the Rapanui and Native Americans, likely occurring between 1250 and 1430 CE. This finding supports the hypothesis of trans-Pacific voyages prior to European exploration. The study involved community engagement with the Rapanui people, ensuring that the research addressed their interests and concerns. The genomic data was obtained through careful sampling of ancient remains, and the results contribute to ongoing discussions about the island's history and the resilience of its inhabitants.
