Ancient DNA paints genetic portrait of Andes civilisations

An international team of researchers including the University of Adelaide, has completed the first large-scale study of DNA belonging to ancient humans of the central Andes in South America and found early genetic differences between groups of nearby regions, and surprising genetic continuity over thousands of years.

In the study, published in the journal Cell, researchers analysed the DNA of 89 ancient humans who lived in the central Andes between 500 and 9,000 years ago, and compared it with the genetic diversity of present day occupants, to shed light on the genetic changes over time.

Ancient Andes, Analyzed

An international research team has conducted the first in-depth, wide-scale study of the genomic history of ancient civilizations in the central Andes mountains and coast before European contact. The findings reveal early genetic distinctions between groups in nearby regions, population mixing within and beyond the Andes, surprising genetic continuity amid cultural upheaval, and ancestral cosmopolitanism among some of the region’s most well-known ancient civilizations.
