The field has moved very rapidly: what seemed extraordinarily ambitious in 2014 — sequencing a 24,000-year-old genome from Siberia — is now part of the routine toolkit of ancient genomics.

The picture that has emerged from this decade of work is more complex and more detailed than what was visible in 2014.

Multiple ancient genomes from Siberia, spanning from the period of MA-1 through the post-glacial period, have revealed additional representatives of the Ancient North Eurasian genetic heritage and have helped trace how that heritage was diluted and modified over time as populations moved and mixed.

The ancient genomic record from the Americas has expanded dramatically, revealing the demographic history of Native American populations across two continents in unprecedented detail.
