Researchers analyzed the genomes of 317 Indigenous Oceanian people to reconstruct a history of migration through the vast island region.

It was one of the boldest journeys in human history: People ventured into the open Pacific Ocean in double-hulled canoes, crossing thousands of kilometers to find and settle far-flung lands. Now, a study of the genomes of hundreds of modern Indigenous residents of Oceania provides new insights into the routes those ancient voyagers took—and who they encountered along the way. The findings suggest more mingling among ancient people in the region than many scientists had thought, including four mixing events with the extinct Denisovan lineage. Despite those intriguing results, critics say the authors failed to meaningfully involve members of the Indigenous communities who provided DNA for the study.
