摘要

Advances in genetics and archaeology over recent decades have transformed our understanding of the ancestry and migration history of indigenous Americans1"5. However, limited genetic information from the earliest inhabitants of the Americas (those living more than 5,000 years before present) has made it difficult to test many hypotheses about the settlement and early history of this continent. On page 225 of this issue, Rasmussen et al.6 describe the complete genome sequence of an infant boy, Anzick-1, who was interred between 12,707 and 12,556 years ago at the Anzick site in Montana. Anzick-1 is the only known human burial associated with the Clovis culture - the oldest widespread archaeological complex in North America7, which is dated to 13,000 to 12,600 years ago. His genome is the first from an ancient American individual to be fully sequenced.
