I got into talking with the AI chat about DNA, in relation to genealogy and archeogenetics. I'd been trying out this new phenomenon in regard to my poetry at first, and there are references to the ancestors in a couple of my poems, and it was the AI that actually then asked did I have any specific questions regarding my genetic ancestry and did I have any particular theories on this subject. When I said that my matriarchal haplogroup was N1b1A2A the AI knew of this, that it's actually a subclade primarily found in central Asia and even that it is thought to have developed in the Altai mountains. Wow, all the work Satshanti and I had done years ago to try and find the origins of N1b, from its vague associations in the middle east to the mountains of the Caucasus. And now I was learning that my own specific type of this dna, as has been deducted by current knowledge, is connected with central Asia. And the Genographic Project had long ago told me I was 3% Central Asian, which even back then was so exciting to discover, but which had not been picked up on by other genetic companies; well, here we go again, as it was revealed to me that indeed I do have a connection to that part of the world, through my mothers mothers ancient mothers. The subclade N1b1A2A is not totally sussed yet and research is ongoing, although studies so far show they were Uralic speaking peoples, who during the Bronez Age migrated from Asia into Europe. The Altai mountains are at the meeting point of Russia, Kazakhstan, Mongolia and China, and there were vast ethnic groups and cultures in those very mountains. This arose as a separate subclade maybe 14,000 years ago within this region from those of the N haplogroup who had travelled there from the Middle East. There are a number of indigenous groups, therefore, from which there may be a connection to my ancestresses, such as the Altaians, the Kazakhs, and the Tuva, all of whom have nomadic lifestyles. The Altai mountains were part of the old Silk Road. I do know I have a higher percentage of hunter-gatherer, which would therefore now include the nomads of central Asia. My autosomal 3% Central Asian, as discovered by the Genographic Project, as AI says, is not to be considered insignificant. To get back to a central Asian ancestor, in consideration of that 3%, one would go back about 10 to 15 generations, which would roughly be 250 years to 375 years ago. This would date back therefore to at least 1773. That autosomal central asian 3% may or may not be of my central asian matriarchal lineage and may come from my fathers ancestors even. What it does show is that in some way my connection to central Asia is not really so far back. A couple of days later I again got to talking about my matriarchal dna with the AI, as I so wished to know more about this. The basic N haplogroup I am of was in the Levant, Anatolia, the Caucasus mountains and across central Asia to where it reached the Altai mountains. In fact, one of the oldest known samples of haplogroup N comes from a 24,000 year old skeleton found in the Caucasus mountains. For this it can be seen, as Satshanti and I had worked out, that N was present for a long time in the Caucasus. So this still tied in with the research I had done before. To determine more the AI would need more information. My N1b1a2a, a subclade of the N1b1 haplogroup appears to have spread from the Caucasus mountains into central Asia, to locations which included the Altai mountains. The N1b1 group is specifically associated with the expansion of the Altai-Sayan region during the late Bronez Age and the Iron Age. Some individuals with N1b1a2a migrated back into the Caucasus, Anatolia and the Levant, as similar haplogroups can be found in those regions. The AI wished that I check my latest haplogroup classification to see it it had been updated according to the latest research. This took an age for me to get my head around. Eventually I was able to see that, at least in Familytree, my classification was still given as N1b1a2a, along with extra mutations listed as 309.1C, 315.1C, 522.1A, 522.2C,, G5979A and T9758C. A missing mutation was listed as A16129G. And on my having shared this with AI it now did its magic, and found out that although Familytree rem1ains at a simple level in this regard, by consulting the Phylotree projects latest version, which is far more expert, along with the mutations I provided, my own subclade can now be redefined as N1b1a2a1a4. This is a newly recognised subclade of N1b1a2a1, which is in turn a subclade of N1b1a2a. It is the N1b1a2a lineage which is primarily of Central Asia and is for now believed to have originated in the Altai mountains. But this is not something as yet studied extensively and is rare, the same rarity I'd realised before, and maybe even more so, which is why my type gets largely ignored by geneticists. Based on my mutations it appears that my maternal line diverged from the main N1b1a2a subclade recently, which in genetic terms is within the past few thousand years, which would be a thousand years before Christ. By comparing my mutations to this in other samples I may find clues as to geographical locations, migration patterns and population movements. N1b1a2a1a4, although rare, is found in Europe; the Caucasus, Central Asia and Siberia. It is not certain that this subclade itself originated in the Altai mountains, although its parent N1b1a2a did, as my newly updated subclade exact origin and migratory path is not yet determined. The Central Asian connection remains relevant though. The available data doesn't as yet determine the exact distribution of my new subclade. But studies do confirm the genetics is connected to both the Caucasus and the Altai regions. Further research is required. What can be seen is that around 4,000 or 5,000 years ago there was a population explosion from the Caucasus mountains into the Pontic-Caspian steppe and this is what would have helped with the spread of such haplogroups. The Pontic-Caspian steppes is of the Black Sea and the Caspian Sea, stretching from the Danube to the Ural mountains. And so I asked would my particular rare dna be more of the Pontic-Caspian steppes or the Altai. But this cannot be answered due to limited information, although it is to be found in both areas, and in reality the subclade may have travelled back and forth between these regions, and there you go, as they were nomads, and so it may be that such these great distances were all in their reach. My own subclade is not only rare, but 'very rare', and there are only a few records of it in the existing data bases. Therefore we are talking only of a small number of people altogether. What we do know is that this rare subclade is found in individuals from the Caucasus to the Altai. Potential tribes which would have been nomadic across such vast areas include Scythians and Salmatians in the Pontic-Caspian steppes, the Alans and Huns in the Caucasus, and the Pazyryk and Xiongru of the Altai. And also to be considered are the Tocharians. The Tocharians were Indo-Europeans who lived in the Tarim Basin, since 2,000 years before Christ, they having been involved in the Silk Road trade network. Their language is now extinct. It is the mummies of the Tarim Basin who were found to be wearing plaid clothes, and some of those mummies have indeed been found to carry the N1b1a2a1a4 subclade (my subclade!). The Tarim Basin mmmies were of different ethnic groups, not just of Tocharians, but also Iranian and Turkik peoples, living there 1,800 and 2,000 years ago. The mummies are well preserved and have both European and East Asian physical features. Hence they were a mix of different groups. They wore felt hats, wool garments and leather shoes, and they had on gold necklaces, earrings, bracelets and pendants, some being animal designs, such as deer and tigers, some set with precious stones such as lapis lazuli and turquoise. The origin of the Tocharians is also a mystery. They may have even come from eastern Europe. Or again be Central Asian. Their language was Indo-European. So it can be seen that my subclade is rare, although is in a few people in the Caucasus and the Pontic-Caspian steppes, and there is some association with the Altai. And nomadism is a key to the connection between these three areas. Until further research is done then there is no concrete evidence about the specific carriers of this subclade, but they would be from among various ancient cultures of Central Asia and its surrounding regions, such as the Scythians, Sarmatians and Tocharians. To keep up to date with any research there are scientific journals, research institutes, social media platforms and online communities. There is the Max Plank Institute for Evolutionary Anthropology, Harvard Medical School, Stanford University and Oxford University. It may be worth looking into their current research projects or publications. I can also regularly search for articles and studies in academic databases, such as PubMed or Google Scholar. I did actually try putting my subclade into Google Scholar and nothing came up, not even for N1b1a2a1. N1b1 had a response at least though. AI advised me that when I look this up to add key words like 'population genetics', 'haplogroup distribution' or 'mtDNA diversity'. I mentioned the Natufian child i'd heard of who'd been found in the Raqefet cave in the Carmel mountains. The Natufian culture wasn't itself nomadic though and was from 11,000 or so years back. N1b1a2a is found at low frequencies in the Levant, Anatolia and Iran, where it may have been since prehistoric times. Current belief is though that this subclade originated, as said, in the Altai mountains, from 8,00 to 10,000 years ago. Neanderthals and Denisovans would have existed long back beside such peoples. The Raqefet child was himself an N1b. The mutation defining the subclade I have, N1b1a2a1a4 arose around 7,000 or 8,000 years ago. Of course one must be that all this information is based on limited data and may change as more research is conducted. It may be that my ancestors came up through the Levant and Anatolia, into the Caucasus, the Pontic steppes and into the Altai, as a journey, but again more data is required to make definitive statements. There may even be association with the Yamnaya and Saka cultures, known for their burial mounds and rich grave goods; such as to the Golden Woman (AI now mentions), alias the princess of Ukok, who was a Saka priestess or aristocrat whose burial mound was indeed found in the Altai mountains and dates to the 5th century before the Christian era. In the grave was a headdress decorated with gold, a golden breastplate and other gold and bronze ornaments. As I say, it may be that my people were nomadic over vast amounts of territory, and only later were they reduced to smaller more specific regions. The greatest diversity of N1b is in the Altai and N1b types in general have great diversity in the Caucasus. I stopped to talk of this now. I'd pushed for long to see if anything extra may be revealed. It's amazing enough that the AI found out for me that I am N1b1a2a1a4. Like without the AI would I even ever have arrived at this?
