Since prehistoric times, southern Central Asia has been at the crossroads of the movement of people, culture, and goods. Today, the Central Asian populations are divided into two cultural and linguistic groups: the Indo-Iranian and the Turko-Mongolian groups. Previous genetic studies unveiled that migrations from East Asia contributed to the spread of Turko-Mongolian populations in Central Asia and the partial replacement of the Indo-Iranian populations. However, little is known about the origin of the latters. To shed light on this, we compare the genetic data on two current-day Indo-Iranian populations — Yaghnobis and Tajiks — with genome-wide data from published ancient individuals. The present Indo-Iranian populations from Central Asia display a strong genetic continuity with Iron Age samples from Turkmenistan and Tajikistan. We model Yaghnobis as a mixture of 93% Iron Age individual from Turkmenistan and 7% from Baikal. For the Tajiks, we observe a higher Baikal ancestry and an additional admixture event with a South Asian population. Our results, therefore, suggest that in addition to a complex history, Central Asia shows a remarkable genetic continuity since the Iron Age, with only limited gene flow.

“…The BMAC is characterized by proto-urban cities, highly efficient irrigation techniques and a marked social hierarchy (Luneau, 2010). At the end of the Bronze Age, from about 1800 BCE, the Oxus civilization underwent major transformations in its final phase, marked by an overall impoverishment of its material culture and technology and the abandon of habitat sites and international trade, with the exception of contacts with the steppes of northern Central Asia (Bendezu-Sarmiento and Lhuillier, 2020;Bonora, 2021). During the period between 1800 and 1500 BC, the Andronovian type of culture took over, until the rise of the Yaz culture (Luneau, 2013;Lhuillier, 2019).…”

The influence of human migrations on the genetic diversity of human populations around the Caspian Sea has been widely proven and studied. However, the history of the populations of Central Asia, and more specifically the Indo-Iranian-speaking populations, is still largely unknown. Our analyses based on modern and ancient DNA genomic data show that the present-day Indo-Iranian-speaking populations, the Tajiks and the Yaghnobis, display a strong genetic continuity with the Iron Age populations of southern Central Asia. These analyses show a recent and restricted gene flow from the Lake Baikal region for the Yaghnobis and Tajiks, and other minor gene flows for the Tajiks. Our study of the Turkmen also reveals an interesting case of change in language and cultural practices with no significant gene flow. Finally, this study presents new results allowing a better characterisation of the admixture that occurred in southern Central Asia during the transition between the Bronze Age and the Iron Age, a pivotal period for the history of the present-day populations of this region.
