Hovann Simonian and Peter Hrechdakian delivered the 18th Annual Vardanants Day Armenian lecture on their work using social media to expand the nonprofit Armenian DNA Project, a Facebook group of more than 1,000 members around the world involved in researching Armenian family history through genetic testing.

A group of Danish, Armenian, Russian and British scientists has found out that women in Armenia and Artsakh have not changed considerably in the last 8 000 years from the point of view of genetics, Lenta.ru reports.

“This is quite interesting, as the region has undergone many cultural changes during the same period. However, these changes have nothing to do with genetic transformation, at least in case of women,” said Ashot margaryan and Morten Allentoft, co-authors of an article published in Cell Press journal.

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.

Mitochondria are passed from mothers to their children. Therefore, the study of mitochondrial genomes enables scientists to trace the unique history of females over time.

“We analyzed many ancient and modern mitochondrial genomes in parts of the South Caucasus and found genetic continuity for at least 8,000 years,” said Ashot Margaryan and Morten E. Allentoft from Centre for GeoGenetics at the Natural History Museum of Denmark. “In other words, we could not detect any changes to the female gene pool over this very long time frame. This is highly interesting because this region has experienced multiple cultural shifts over the same time period, but these changes do not appear to have had a genetic impact — at least not on the female population.”

The researchers were interested to study this part of the world because of its position as a cultural crossroads since ancient times. It’s also known as an important area for the potential origin and spread of Indo-European languages.

To shed light on the maternal genetic history of the region, the researchers analyzed the complete mitochondrial genomes of 52 ancient skeletons from present-day Armenia and Artsakh, an unrecognized republic bordering Armenia and Azerbaijan. Those specimens span 7,800 years of history. Allentoft’s team combined this new data with 206 mitochondrial genomes of modern Armenians and previously published data representing more than 480 individuals from seven neighboring populations.

The findings imply that the female population in at least some parts of the South Caucasus has been highly stable through many cultural shifts that have occurred over thousands of years. They also suggest that documented migrations into this region during the last 2,000 to 3,000 years have had little genetic impact on the local female population. The researchers say the next step is to explore these questions in whole-genome data to see if it tells the same story. They also hope to expand the study by including both modern and ancient samples from neighboring countries, which could involve collaborations with researchers in Georgia and Azerbaijan.
