Genetic evidence from the South Caucasus region shows surprising long-term stability

The South Caucasus—home to the countries of Georgia, Armenia, and Azerbaijan—geographically links Europe and the Near East. The area has served for millennia as a major crossroads for human migration, with strong archaeological evidence for big cultural shifts over time. And yet, surprisingly, ancient mitochondrial DNA evidence reported in Current Biology on June 29 finds no evidence of any upheaval over the last 8,000 years.
