Briefings

Ancient Ecuadorian genomes from Salango reveal 1,500 years of genetic continuity along the Pacific coast. Researchers sequenced four individuals from 2,300, 1,900, and 740 years ago. The study highlights deep genetic continuity in an understudied region of the ancient world.

Key points

• Four ancient Ecuadorian genomes were sequenced from individuals excavated at Salango on the central coast.
• The samples date to approximately 2,300, 1,900, and 740 years ago, demonstrating 1,500 years of genetic continuity.

Context

This research provides new insights into the genetic history of the Pacific coast of Ecuador, specifically the Salango region, which has been an understudied area for millennia.

Limitations

The evidence is limited to four individuals from a single excavation site. The study does not provide broader regional genetic patterns or long-term population history.
