They were subsequently joined and largely displaced around 1,000 years ago by ancestors of the present-day Inuit and Yup{\textquoteright}ik1,2,3. The genetic relationship between Palaeo-Eskimos and Native American, Inuit, Yup{\textquoteright}ik and Aleut populations remains uncertain4,5,6. Here we present genomic data for 48 ancient individuals from Chukotka, East Siberia, the Aleutian Islands, Alaska, and the Canadian Arctic. We co-analyse these data with data from present-day Alaskan I{\~n}upiat and West Siberian populations and published genomes. Using methods based on rare-allele and haplotype sharing, as well as established techniques4,7,8,9, we show that Palaeo-Eskimo-related ancestry is ubiquitous among people who speak Na-Dene and Eskimo{\textendash}Aleut languages. We develop a comprehensive model for the Holocene peopling events of Chukotka and North America, and show that Na-Dene-speaking peoples, people of the Aleutian Islands, and Yup{\textquoteright}ik and Inuit across the Arctic region all share ancestry from a single Palaeo-Eskimo-related Siberian source.}}, journal = {{Nature}}, volume = {570}, pages = {236--240}, }
