New evidence from West Papua offers fresh clues about how and when humans first moved into the Pacific
The first humans to reach the Pacific islands likely came from Southeast Asia, but the details of their journey have long been debated.
A new study published in the journal Nature Ecology and Evolution suggests that the first humans may have arrived in the Pacific as early as 50,000 years ago, much earlier than previously thought and potentially predating the appearance of Homo sapiens.
The study analyzed mitochondrial DNA from ancient human remains found in West Papua, Indonesia, which is located near the Wallace Line, a biogeographic boundary between the Asian and Australian faunal regions.
The results showed that the ancient West Papuans were genetically most closely related to modern Indigenous Australian and Papuan populations.
The researchers also found evidence of gene flow between the ancient West Papuans and an unknown hominin population, suggesting that there may have been multiple waves of migration into the Pacific.
The findings provide new insights into the genetic history of the Pacific region and the origins of its diverse populations.
They also suggest that the first humans may have been more adaptable and mobile than previously thought, able to traverse long distances across the sea in search of new homes.
The study adds to the growing body of evidence that the Pacific was a center of human diversity and interaction long before the arrival of Europeans.
