In 1906 famous archeologist Hugo Winckler had found some clay tablets in Asia minor i.e in Anatolia, present day Turkey. It was famous treaty between the Hittite ruler Suppiluliuma and the Mitanni king, Mattiwaza,(Mattiraja) about 1370 BCE, the Vedic gods Mithra, Varuna, Indra and the twin Nasatyas are mentioned. Thus in the Mitanni kingdom Aryan gods were worshipped as well as Mesopotamian deities, which proves an Aryan Vedic element. In a famous tablet, we have the seal of Prince Suttarna, son of Kirta, King of Mittani in which two lions are defeated by a central single human- headed lion-in bird costume;mid second millennium BC.
The Mitanni kingdom was a (non-IE) Hurrian language speaking kingdom, but it was founded and ruled by a clan of kings, the Mitanni kings, who were originally of linguistically Indo-Aryan stock. The Indo-Aryan (Vedic) element was already a residue of their ancestral culture, and is reflected in the names of the kings of the Mitanni dynasty and in many key words in their extant documents and inscriptions. This kingdom lasted for more than 200 years, and records of the Mitanni kings are found as far west as in Palestinian and Egyptian records ̶ the Egyptian queen Nefertiti is originally believed to have been a Mitanni princess. The clay tablets are written in cuneiform script in Hurrian language with loan words from Indo Aryan language. So it was the Indo Aryan people who were ruling over Hurrian peoples.
Hurrian language, extinct language spoken from the last centuries of the 3rd millennium BCE until at least the latter years of the Hittite empire (c. 1400–c. 1190 BCE); it is neither an Indo-European language nor a Semitic language. It is generally believed that the speakers of Hurrian originally came from the Armenian mountains and spread over southeast Anatolia and northern Mesopotamia at the beginning of the 2nd millennium BCE. Before the middle of the 2nd millennium BCE, parts of Hurrian territory were under the control of an Indo-Aryan ruling class, the Mitanni, whose name was incorrectly applied to the Hurrians by early researchers.
In particular treaty, between the Hittite King Shuppilulima and Mattiwaza (Mattiraja), king of the Hurrian (Hari)kingdom of Mitanni circa 1350 BC, listed among the divine witnesses “Mitra-ash, Uruwana, Indra, and the Nashatiyanu gods, the very Mithra, Varuna, Indra, and the Nasatya gods of the Vedic pantheon”. we have the Mitanni kingdom in Syria-Iraq after 1500 BCE.
Another treatise from the State Archives of the Hittite Empire was discovered in Boghaz-keui in modern Turkey. It is a treatise on chariot racing( horse riding manual)and it uses Indo-Aryan words such as “Aikavartana=One Turn, Teravartana=Three Turns, Panchavartana=Five Turns, Sattavartana=Seven Turns.” So basically Hittite is mainly attested through thousands of clay tablets inscribed in cuneiform writing obtained from the institutional archives of the Hittite state (ca.1650–1180 BCE).
So by the time 2000BCE – 1500BCE there were the presence of Indo Aryan people in Syria and Anatolia. You can see horse and chariots are also being used. Note that we already know from previous post that bronze age Anatolian people don’t have steppe ancestry.
There was a study conducted on the channels of Ghaggar Hakkr river and the paper is published in nature. By using satellite images and hydrological methods it is now proven that there was a huge river that used to flow in ancient times. The Ghaggar Hakkr is the small seasonal stream which remains in the area and the underground river channels revealed in the satellite image is a proof of a prominent and huge river system that existed once. The large number of Harappan sites are found in the area of the river channels between Yamuna and Sutlej (infact the Harappan settlements are more concentrated in these areas than Indus river.
“A thorough scrutiny of the settlement dynamics of the Harappan Civilization reveals that the timing of the rejuvenated perennial phase of the Ghaggar (9-4.5ka) coincides with that of the fourishing of the Pre-Harappan and Early Harappan cultures along its banks (Fig. 3B). Towards the end of the Mature Harappan phase (4.6-3.9 ka), there is a clear evidence of human migrations to the lower and upper reaches of the river, leaving the middle part sparsely populated (Fig. 3B), which could be attributed to the disorganization of the river as established in this work. Te lower reaches of the river, in the Hakra sector, had possibly remained perennial, through a connection from the Sutlej, supporting mature and post-urban Harappan settlements (Fig. 3B). Our study brings to light the fact that the Harappans built their early settlements along a stronger phase of the river Ghaggar, during ~9 to 4.5 ka, which would later be known as the Saraswati. However, by the time the civilization matured, the river had already lost its glacial connection. Tese inferences confrm the observation of an earlier study, based exclusively on changes in the settlement patterns, that the Ghaggar frst broke up at ~4.6 ka12. Interestingly, the timing of the ultimate disruption to the perennial phase of the Ghaggar roughly coincides with the beginning of the Meghalayan Stage (~4.2 ka). Te urban Harappans abandoned their settlements in the Ghaggar valley within next few centuries and the civilisation declined by 3.9ka. Although, the decline of the civilization in the Ghaggar-Saraswati valley postdates the exceptional changes to the fow of the river, a stronger perennial phase appears to have helped the early societies to sow the seeds of the earliest known civilization of the Indian subcontinent.”

You can see from the figure that Harappan settlements are moved away from Ghaggar Hakkr SS line(saraswati river) during the transition from matured to post Harappan times. This coincides with the Meghalayan period (4200 yrs ago).
In another genetic paper about cattle genomics
“A later region-wide Bronze Age shift indicates rapid and widespread introgression of zebu, Bos indicus, from the Indus Valley. This process was likely stimulated at the onset of the current geological age, ~4.2 thousand years ago, by a widespread multicentury drought. In contrast to genome-wide admixture, mitochondrial DNA stasis supports that this introgression was male-driven, suggesting that selection of arid-adapted zebu bulls enhanced herd survival. This human-mediated migration of zebu-derived genetics has continued through millennia, altering tropical herding on each continent.”

“However, after ~4000 yr B.P., hybrid animals (median 35% indicine ancestry) are found across the Near East, from Central Asia and Iran to the Caucasus and Mediterranean shores of the southern Levant(table S2 and fig. S1). During this period, depictions and osteological evidence for B. indicus also appear in the region.”
Page no 2
The paper says that Bos Indicus ( indigenous cattle breed of Indus valley) had travelled to Caucasus and to Anatolia (Near East) after 4000BP(before present).
“This multicentury drought coincided with empire collapse in both Mesopotamia and Egypt as well as a decline in the Indus civilization and has been accepted as the boundary defining the onset of our current geological age, the Meghalayan.……..
…..
Westward human migration has been documented around this time (19, 20) along with archaeological evidence for the appearance of other South Asian

taxa such as water buffalo and Asian elephants in the Near East, suggesting the movement of large animals by people.”
If we incorporate both the papers (cattle genomics, Ghaggar Hakkr) it can be evident that both people and domesticated animals are migrated from Indus valley as a result of drought.
But Zebu genetic inheritance is not just restricted to the Caucasus and it extends to the ancient steppe cattle as well. According to a study of ancient and primitive European DNA,
“The divergence of the BAI cattle as suggested by PCA (Figure 2c) can be attributed to an indicine genomic component which is identified in the ADMIXTURE (Figure 3) and D-statistics (Table 2) analyses. By analysing the genome-wide SNP markers, McTavish et al. (2013) and Decker et al. (2014) also reported an indicine influence on Italian cattle breeds. Using whole-genome sequences of ancient human DNA, Jones et al. (2015) and Haak et al. (2015) suggested massive migration of Yamnaya steppe herders as a source of dispersion of Indo-European languages to both northern-central Europe and India.
Page no 173
These herders might also have mediated gene flow between Indian Zebu and Ukrainian steppe cattle.”
Even there is evidence of Asian elephants which is found in thick forests of South East Asia in desert land of Syria(South West Asia) from the paper
“In Southwest Asia, the earliest representations of elephants appear in art and mythological literature, originating from eastern Lower Mesopotamia, and date to the end of the 3rd millennium BC (Potts 1997: 260–61). The style of depiction, though, seems to derive from that of the Indus Valley (Salonen 1976: 146–47). This strongly suggests a second-hand knowledge of elephants, rather than first-hand, real-life experience. From Greece to Arabia, no single reference to, or depiction of, an elephant or elephant parts, ante-dates these first finds from the end of the 3rd millennium BC. This consolidates other evidence that shows that the Holocene elephants of Southwest Asia were not endemic to the region and that the Early Bronze Age peoples of the region knew about them only through their contact with India, or possibly Egypt. The latter is less likely as these animals were no longer indigenous there by that time, although remembered (Osborn and Osbornová 1998: 125–31).”

“It is interesting that raw ivory, rather than finished objects of elephant ivory, make their appearance in Lower Mesopotamia at around this time (Potts 1997: 261). This adds to the plentiful archaeological evidence for intensifying relations between Southwest Asia and the Indus Valley and implies greater control by humans over Asian elephant populations in South-east Asia. When and where the Asian elephants became ‘tamed captives’ (sensu Zeder 2012) has not been investigated zooarchaeologically, but pictorial depictions point at a date around the mid 3rd millennium BC, occurring somewhere in India.”

There is ancient dog DNA from a Corded ware site that shows possible Indian dog and Indian wolf admixture. The study involved aDNA from 3 dog samples, one of which, labelled as CTC, came from a corded ware site in Germany. Corded ware culture, as many here would know, is considered the 1st IE culture in Europe proper which was heavily influenced by Yamnaya groups from steppe.
“Our results are consistent with continuity of a European-like genetic ancestry from modern dogs through the entire Neolithic period. However, the slightly displaced position of the ancient samples from the European cluster in the PCAs (particularly for CTC) suggests a complex history. We therefore performed unsupervised clustering analyses with ADMIXTURE (SNP array data; Supplementary Fig. 15) and NGSadmix (whole-genome data; Fig. 4 and Supplementary Fig. 16) (Supplementary Note 9) and found that, unlike contemporary European village dogs, all three ancient genomes possess a significant ancestry component that is present in modern Southeast Asian dogs. This component appears only at very low levels in a minority of modern European village dogs. Furthermore, CTC harbours an additional component that is found predominantly in modern Indian village as well as in Central Asian (Afghan, Mongolian and Nepalese), and Middle Eastern (Saudi Arabian and Qatari) dogs (concordant with its position in the PCA), as well as some wolf admixture.”
Page no. 4
Note the time period of CTC specimen
“The older specimen, which we refer to hereafter as HXH, was found at the Early Neolithic site of Herxheim and is dated to 5,223–5,040 cal. BCE (B7,000 years old) (Supplementary Fig. 1). The younger specimen, which we refer to hereafter as CTC, was found in Cherry Tree Cave and is dated to 2,900–2,632 cal. BCE (~4,700 years old), which corresponds to the End Neolithic period in Central Europe. “

The below admixture graph from the same paper explains the likely path of admixture from Indian dogs into the Corded ware CTC dog sample.
But not only is there evidence of cattle migration from South Asia to the Caucasus and the steppe, there is also evidence of possible sheep migration.
As per this study on mtDNA diversity in Indian sheep,
“Previous studies on mitochondrial DNA analysis of sheep from different regions of the world have revealed the presence of two major- A and B, and three minor- C, D and E maternal lineages. Lineage A is more frequent in Asia and lineage B is more abundant in regions other than Asia. We have analyzed mitochondrial DNA sequences of 330 sheep from 12 different breeds of India. Neighbor-joining analysis revealed lineage A, B and C in Indian sheep. Surprisingly, multidimensional scaling plot based on FST values of control region of mtDNA sequences showed
Page no 1
significant breed differentiation in contrast to poor geographical structuring reported earlier in this species. The breed differentiation in Indian sheep was essentially due to variable contribution of two major lineages to different breeds,
and sub- structuring of lineage A, possibly the latter resulting from genetic drift. Nucleotide diversity of this lineage was higher in Indian sheep (0.014 ± 0.007) as compared to that of sheep from other regions of the world (0.009 ± 0.005 to 0.01 ± 0.005). Reduced median network analysis of control region and cytochrome b gene sequences of Indian sheep when analyzed along with available published sequences of sheep from other regions of the world
showed that several haplotypes of lineage A were exclusive to Indian sheep. Given the high nucleotide diversity in Indian sheep and the poor sharing of lineage A haplotypes between Indian and non-Indian sheep, we propose that lineage A sheep has also been domesticated in the east of Near East, possibly in Indian sub-continent. “
Haplotype A is more widespread and frequent in Asia while mtDNA haplotype B is more common in Europe.
The above is an map from another paper which shows the relative distribution of various sheep mtDNA lineages. One can observe that the mtDNA A lineage (in Blue) predominates in Asia while mtDNA B (in Red) predominates in Europe. However, it is also evident that mtDNA A has a significant presence in the Caucasus as well as on the European steppe and Northern Europe. Considering its likely origin in South Asia and its presence in the Caucasus and steppe, this may again indicate that a sheep lineage spread out from South Asia to these two regions along with the Zebu cattle and was accompanied by human migration as well.
Whether it be domesticated cattle, sheep, Elephants or dogs, their movement is usually associated with the movement or migration of humans. In this case, we can see migration into the steppe of all three domesticated species from a likely origin in South Asia. So can we also detect some signs of human migration into the steppe. While we have clearly seen the signs of human migration from South & Central Asia into the Caucasus associated with a cultural and technological package, such evidence for steppe is much harder to come by. More so because of the absolute rarity of aDNA from South Asia.
