Remarks on Skourtanioti 2024 paper on the Genetic History of South Caucasus

Elamites

Amjadi et al. (2025) published ancient DNA from the Chalcolithic period in the South Zagros, dated to around 4600 BC. The sample comes from the Gol Afshan Tepe site and is associated with the Bakun period, which immediately precedes the so-called Lapui period (4100–3500 BC), often linked to the Proto-Elamites.

Assuming there was no major population shift between the Bakun and Lapui periods, we can reasonably suggest that the Proto-Elamite language developed among populations with a strong Zagros/Iran Neolithic genetic component. This is supported by autosomal data, as well as the presence of Y-DNA haplogroup R2, which was common among ancient Zagros farmers and today is found mostly in South Asia and parts of West Asia (for example, among some Armenians from Sasun).

The Elamite civilization flourished in the southwest of the Iranian plateau. The Elamite language was widely used as an administrative language in the Achaemenid Empire. The Persians referred to the region as Hujiya > Khuzi, from which the modern name Khuzestan derives. Interestingly, Elamite may have survived into the medieval period—Arab sources mention an incomprehensible “Khuzi” language distinct from Persian in that region.

There is even a linguistic echo in Armenian: the word khuzhan (խուժան), meaning “hooligan” or “wild person,” is derived from that regional name.


Possible implications

If future research confirms a strong link between Elamites and Zagros Neolithic populations, several important conclusions may follow:

  • Sumerian is likely unrelated to Elamite, suggesting it originated from a different population, often referred to as “Central farmers,” rather than Zagros farmers.
  • Northern Iran had a different genetic trajectory.
    A Chalcolithic sample from the Urmia basin (Hajji Firuz) is shifted toward western populations and clusters closer to Central farmers. This suggests eastern migrations diluted Zagros ancestry in northern Iran, where other groups—such as the Kassites—later appeared. Kassites are not clearly linked to Elamites, though connections with Hurrians have been proposed.
  • Elamo-Dravidian hypothesis gains some support.
    The idea that Elamite is related to Dravidian languages is still debated, but a Zagros Neolithic origin could strengthen this theory. That said, Dravidian populations also carry strong South Asian-specific ancestry (including Andaman-related hunter-gatherers).
  • Language vs. population mismatch in empires.
    The widespread administrative use of Elamite in the Achaemenid Empire shows that a language’s presence in inscriptions does not necessarily reflect the dominant spoken language of a region.
    This is relevant for understanding Urartian (Biainili) as well: inscriptions alone don’t prove linguistic dominance. For example, Elamite inscriptions have been found in Armavir (Armenia), yet that doesn’t imply Elamite-speaking populations lived there in large numbers.
