Abstract
Summary of the research findings
The study analyzes 2,456 mitochondrial genomes spanning Indigenous Australians, New Guineans, and Oceanians (including an archaeological lineage from Wallacea), re-evaluates the mitochondrial mutation rate, and considers genome-wide and Y-chromosome data alongside archaeological and climate evidence. The results support a long chronology for first settlement of Sahul around 60,000 years ago, with at least two distinct dispersal routes into the region.
