Nature - The eventful settlement history of South Pacific islands Knowledge about the genetic diversity of human populations is essential to better understanding of overall settlement history and natural selection processes. However, the vast majority of genetic studies focus on populations of European origin, which represent only 16% of the world population. The genomic history of the South Pacific, on the other hand, has hardly been studied. In a new study published in Nature, an international research group led by the Institut Pasteur, the Centre National de la Recherche Scientifique (CNRS) and the Collège de France has studied the settlement history of the inhabitants of the Pacific islands using genome sequencing. Our laboratory was involved in the demographic and historical inferences of the genomic data, which were analysed mainly with computer software developed in our group. The study, confirms archaeological findings that place human settlement of various islands in Oceania around 40,000 years ago. Furthermore, the scientists were able to prove that a period of genetic isolation between the islands followed this initial settlement.
