The complex history of the ancestral Indo-European population has given birth to numerous competing theories regarding its origin. The Proto-Indo-European language was probably a fusional language, while the Uralic languages are agglutinating languages. Ancient agglutinating languages are also thought to be present in the Near East in the past.

“Bronze and Iron Age population movements underlie Xinjiang population history” addressed the ancient Indo-European Afanasievo population, but also addressed autosomal components of similar percentages to the ones, forming Near Eastern and Steppe populations in the western article of “A Genetic History of the Near East from an aDNA Time Course Sampling Eight Points in the Past 4,000 Years”, in which the East African Nilo-Saharan Gumuz population, speaking a highly agglutinating language, was used as an outgroup to ancient Near Eastern and Steppe populations.

The ancient individual C3341, having come to Xinjiang from the West, whose yDNA produced calls for yDNA R1b1a2a1a-L51 (ISOGG 2011) and, most importantly, for yDNA R1b1a1b1a1-L52 (which are both today mainly observed in Western Europe) and whose mtDNA was mtDNA R1b1 (which is extremely rarely observed in Indo-European Netherlands’ (ancient), Italy’s (ancient), Austria’s, Armenia’s, India’s populations, but is also observed in the Uralic Finnish population) could be modeled as 100% ancient Afanasievo in “Bronze and Iron Age population movements underlie Xinjiang population history”.

The mentioned mtDNA R1b1 has a mutation G513A, which is shared with lineages, whose Western Eurasian cases (observed in both Europe and Asia) include a lot of lineages, belonging to Neolithic Farmers, observed in both Europe and Western Asia:

G513A R1b1
G513A H1-a5
G513A H1au3a
G513A H1c1o
G513A H1c43a
G513A H10a1b
G513A H24a2a
G513A H35a1a
G513A H4a1a3a1
G513A H47a1a1
G513A H5a1j5
G513A H5a1z
G513A H5a3
G513A H9a4
G513A V25b
G513A R0a1a1a1
G513A J2a1a
G513A J2a2d1a3
G513A T1a1b-a3
G513A T2b71b
G513A T2b23a2a1

The Finnish population was assigned a branch of an mtDNA H1a lineage, which is deeply diverged (10400 years ago) in “Ancient Mitogenomes Reveal the Origins and Genetic Structure of the Neolithic Shimao Population in Northern China”.

In the western article of “A Genetic History of the Near East from an aDNA Time Course Sampling Eight Points in the Past 4,000 Years”, there is a component, formally named “EHG”, amounting to 25%, contributing to a Neolithic Iranian population (using which the Pakistan_Iron_Age is formed, which is sometimes thought to be related to Indo-Aryan/Indo-Iranian-speaking populations), contributing to an ancient Steppe population as well as contributing to one more Near Eastern population, more shifted to Neolithic Farmers of Anatolia on the PCA. “Bronze and Iron Age population movements underlie Xinjiang population history” revealed that a 25% autosomal component, characteristic of the ancient Afanasievo population, could be used to model a pare of ancient individuals, arriving to Xinjiang from the West, whose yDNA produced the following calls:
− S21728 I2-Y6021*
− S21728 R1b>R1b-U106> R1b-S21728
− Z94 • F3105 • S340 I2-Y47373*
− Z94 • F3105 • S340 R1a-Z94

Consequently, it is not impossible that male lineages, ancestral to R1b-U106 and R1a-Z94, accompanied by a female lineage R1b1, as well as, perhaps some other male lineages, lived close by and finally settled in the intermediate location between Anatolia and Iran (e.g., in the vicinity of Armenia) and interacted with lineages, living in the Near East, and a part of them later migrated to the north to contribute to local Steppe populations, while a part of them contributed to Indo-Aryan/Indo-Iranian-speaking populations.

Moreover, in “Bronze and Iron Age population movements underlie Xinjiang population history”, the ancient Afanasievo population was additionally characterized by some component, shared with the individual of the native Near Eastern origin, who, perhaps reached Xinjiang, having become a part of an Indo-European-related population. The yDNA lineage of this ancient individual was yDNA J2a1a1b2a1a-FGC16096.

Additionally, the materials of “Bronze and Iron Age population movements underlie Xinjiang population history” suggest that there should have been Neolithic Farmer female lineages to interact with, whose mutations are shared with lineages, which are today observed in tribal populations, speaking agglutinating languages.
