Commenters on this weblog have expressed dissatisfaction with the nomenclature of the “eastern Iranian farmers” who were the dominant genetic contributors to the Indus Valley People. The author of The formation of human populations in South and Central Asia agrees that this is a problem.
To review: the dominant ancestry component, called Iranian-related or eastern Iranian farmer, has two components. About 5-10% is related to “West Siberian Hunter-Gatherers”, who mostly descend from “Ancient North Eurasian” Paleo-Siberian groups (this group contributed ancestry to eastern European hunter-gatherers and Native Americans). The remainder of the ancestry is related to farming populations that are termed “Iranian” from samples in the Zagros in the early Holocene. But the genetics indicates that the separation of the Indian ancestry component dates to before farming, probably between 10-15,000 years ago. Without ancient DNA that is older, we can’t be sure of its geographic range, but it is reasonable to infer that this was an eastern expansion of hunter-gatherers out of the Zagros (seeing as how the WSHG ancestry is not found in the west, and the broader Iranian farmer clade seems to form a clade with Anatolian farmers and Levantine farmers).
But obviously the use of the term “Iranian” confuses with the nation-state of Iran. This has come up when I use terms like “Iranian-speaking people,” and people get confused because they don’t assume that I’m talking about people who live in Russia (Ossetes), or ancient people who flourished in Xinjiang and Ukraine.
Historically modern Iran was called “Persia”, and Iran was actually more of an archaic civilizational term. But in the 20th-century the Pahlavi’s resurrected this ancient term for the nation-state, so here we are.
The question this: what is a better term for the “Iranian-related farmers”? I have often used the awkward “NW South Asia”, since it seems plausible this group was present in modern-day Pakistan by the early Holocene, and probably earlier. Thoughts?
I’m basically asking for terms and why you think those terms are good. I may adopt a term in the comments for usage on my blogs.
Note: We can’t call them “Ancient Ancestral North Indians” (AANI) since the ANI turn out to be a compound of Indus Periphery and Steppe.
