The R1b from Bakr Awa (Mesopotamia) is now published in FTDNA. Its confirmed as Z2106 and is positive to Y100087 snp. This branch has strong presence in ancient remains from Ukraine and Russia. Thus the steppe origin of this Bakr Awa R1b is beyond the doubt.
This is the first case of Y100087 from West Asia, while other cases of Z2106 were from the parallel CTS8966 branch found from Armenia and possibly Levant.
As previously mentioned the best candidate for its affiliation is the Gutian connection. Even though its quite possible that over time he and similar people were assimilated in to locals, but their initial identity might be IE.
Its remarkable that Henning and after him Gamkrelidze and Ivanov proposed the IE origins of Gutians. Even though they linked it to Tocharian which is untenable in current stage of our knowledge.
Now with genetic data on hands lets look closer at Gutian names.
At last three kings have the root Yarla in their name.
- Yarlagab
- Yarla
- Yarlaganda
In most likelihood the 'Yarla' is a Gutian deity name or a dynastic name while the rest are particles or other roots.
Yarla can be compared to Slavic deity Yarilo which has IE origin from *yeh₁r-. Its a Spring deity. The root is present in English in the form of word "year".
Another interesting root is the -gab. Its present in two names
- Sarlagab
- Yarlagab
It fits well with the PIE root ghabh- (also reconstructed as *gʰebʰ-). Which means to give, to hold. A frequent root in names. The English word to give is derived from that root.
Incidently the name Sarlak supports the fact that "Sarl" in Sarlagab is a root. Most probably a deity name. However this name is not from Sumerian king list so we are not sure anout its identity. He could be the same as Sarlagab ( or Zarlagab)
Another possible root is the -gan present in
- Tirigan
- Yarlaganda
Can be compared to PIE root *ǵenh₁. To give birth. Multiple names ending with -es or -us also supports the IE classification. The potential root Tir is also remarkable. It can be compared to Armeno-Iranian deity Tir.
Some other names are obvious Mesopotamian influence. Like Puzur-Suen. While the particle -um in some names is probably an Akkadian.
Summing up the scant Gutian onomastic data we see evidence that can support their IE classification. However the potential IE language behind Gutian names seems to be somewhat different from the Proto-Armenian. It seems to be a centum, while Armenian is satem. It also preserved the phoneme [s] while Armenian converted them to [h] and lost them. What is also remarkable is that their Y DNA was widely present deep in steppe which once more could mean that the Gutian language was a (close?) parallel language to Armenian rather than a simple dialect of Proto-Armenian.
With more ancient DNA we will have more clarity on all aspects of Middle Bronze Age migrations from steppe to West Asia.
