A distinctive human genetic lineage persisted in central Argentina for 8,500 years

The DNA of ancient individuals dating to between 10,000 and 150 years ago reveals the existence of a long-standing, yet previously uncharacterized, lineage in the Southern Cone of South America — a region comprising what is now Argentina, Chile and Uruguay. People with this ancestry produced offspring with other, pre-existing groups in surrounding regions. Genomic data from present-day inhabitants attest to the genetic continuity of the lineage in central Argentina. The lineage is still found today in individuals from the region.

Abstract

The DNA of ancient individuals dating to between 10,000 and 150 years ago reveals the existence of a long-standing, yet previously uncharacterized, lineage in the Southern Cone of South America — a region comprising what is now Argentina, Chile and Uruguay. People with this ancestry produced offspring with other, pre-existing groups in surrounding regions. Genomic data from present-day inhabitants attest to the genetic continuity of the lineage in central Argentina. The lineage is still found today in individuals from the region.
