The 9,000-Year-Old Child’s Tooth Found In An Alaska Cave — And The DNA Test That Revealed A Lost Population Of The First Americans
— COMPLETE FINAL END —
The Broader Arctic Human Genome Record
The Trail Creek child’s ancient genome is one of a growing but still sparse collection of ancient human genomes from the circumpolar Arctic region.
Understanding the broader context of what the Arctic genome record currently includes, and what gaps remain, helps situate the Trail Creek finding within the larger scientific picture.
The Upward Sun River site in central Alaska, with its approximately 11,500-year-old infant remains including USR1, remains the earliest well-dated ancient human genome from Alaska.
The Trail Creek tooth, at approximately 9,000 years, is the next oldest with recoverable genomic data from Alaska proper.
