Significance of Potential Haplogroup N in India
Linguistics provides us with a plausible scenario regarding how Haplogroup N may have arrived in the Indian Subcontinent. Contacts between early Finno-Ugric and Indo-Iranian groups took place around the Ural mountains, specifically between the forest and steppe zones. Evidence of transmission in horsekeeping techniques, economy, deities and common words are firmly established from Andronovo archaeological horizon on the steppes into the "Andronovoid" societies living in the nearby forests. [2]
The presence of Haplogroup N in India, if present in relevant populations and displaying MRCA values or STR clusters consistent with a Neolithic origin further north, would satisfy the likelihood of Haplogroup N representing an accompanying genetic signal from the steppe zone roughly four thousand years ago, as well as serving as a genetic remnant of the interactions that undoubtedly took place between Indo-Iranian and Finno-Ugric tribes.
