Basmaci has alerted me to a genome that was unearthed from Kytmanovo village in Russia North of Altai carbon dated to 720s to 840s AD, which neatly overlaps with the time and place of the Kimek Khanate, comprised of Kipchaks and Cumans, who had left the collapsing Gokturk Khanate into Central Asia just a few decades prior. Since we now have such a wide selection of ancient genomes, we can compare this against the rest to gain a picture of the genetic changes that took place over time, as well as the gene pool that likely lay behind the Turkic expansion. We can also test the findings of Yunsubaev et al
http://journals.plos.org/plosgenetic...l.pgen.1005068
who found that the signal of shared haplotypes for Turkics peaks around Altai populations like Tuvinians, Altaians and Buryats.
Aggregating all the steppic genomes:

Kyrgyz and Altaian were the Turkic populations provided in the Allentoft data, and, sourcing all the same sets of populations from the Scythian paper, we see that the ancient Turkic genome is very similar to Altaian and Kyrgyz, providing strong support for the results of Yusnubaev et al. This is prior to the Mongolic invasions, so the autosome of the Proto-Turkics was probably quite Eastern even before the later periods of gene flow.
The closest genomes we have in time to this sample are Altai_IA, which were cotemporary with Xiongnu but were too far west to fall into the Xiongnu Khanate or to represent their genome, and the Paryzyks, who resemble the Altai_IA very strongly and indeed come from virtually the same place and time in the 5-3rd Century BC. These genomes are quite different from the Turkic Khanate genome and modern-day Turks, and look broadly "Scythian", which they most likely are, judging from historical sources.
Gravetto-Danubian informs us that we are getting more genomes from the historical steppes, and we will see how genomes from the historical core of the Gokturk Khanate turns out in relation to this one.'
