圖書描述

Much of the American Arctic was first settled 5,000 years ago, by

groups of people known as Palaeo-Eskimos. They were subsequently

joined and largely displaced around 1,000 years ago by ancestors

of the present-day Inuit and Yup’ik1–3

. The genetic relationship

between Palaeo-Eskimos and Native American, Inuit, Yup’ik and

Aleut populations remains uncertain4–6

. 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 Iñupiat and West

Siberian populations and published genomes. Using methods

based on rare-allele and haplotype sharing, as well as established

techniques4,7–9

, we show that Palaeo-Eskimo-related ancestry is

ubiquitous among people who speak Na-Dene and Eskimo–Aleut

languages. We develop a comprehensive model for the Holocene

peopling events of Chukotka and North America, and show that NaDene-speaking peoples, people of the Aleutian Islands, and Yup’ik

and Inuit across the Arctic region all share ancestry from a single

Palaeo-Eskimo-related Siberian source
