The origin of the Armenian people is heavily debated among historians and archaeologists. Despite a long history and vast archaeological records in Armenia, it has proven very challenging to infer the demographic events that led to the formation of Armenians as a distinct ethno-cultural group. To obtain a detailed understanding of the demographic events in Armenia across millennia, we study complete mitochondrial genomes from 49 ancient individuals covering 7800 years and compare them with with that of modern Armenians (n=206) and seven neighboring populations (n=482). In this context, the lowest genetic distance was observed between the modern and ancient Armenians and this was also reflected in network analyses and discriminant analysis of principal components (dapc) showing genetic proximity between the ancient individuals and modern Armenians. We used Approximate Bayesian Computation (ABC) to test five different demographic scenarios of the Armenian population, and the simulations favored a model where both ancient and modern Armenians derive from the same source population. We conclude that there is a strong signal of continuity in the maternal Armenian gene pool during the last 7800 years.
