In the dropbox file of supplemental material some info on haplogroups, mainly R1b, G2a and I2; some of the Yleaf downstream calls seem too modern though.

Zhagunluke culture, as one of the Iron Age cultures in southern Xinjiang, was the representative of the ancient Qiemo kingdom that showed diverse cultural elements and the coexistence of agriculture and livestock farming. However, the genetic structure and formation of ancient Qiemo people were unclear. Here, we reported the ancient genomes of two individuals from Zhagunluke No.1 cemetery. Combined with previously published data, we observed that most Zhagunluke samples showed genetic admixtures between East and West Eurasians with varying proportions of ancestry. However, we also found a genetic outlier with dominant millet farmers-related ancestry from the Yellow River or the West Liao River basins. The genetic substructure of the Zhagunluke population demonstrated multi-way demographic interactions in Iron Age southern Xinjiang with populations from the surrounding areas of Western Steppe, Central Asia and East Asia.

•∼6% of the Altai Neanderthal genome was inherited from anatomically modern humans
I'm wondering if this admixture is what defines Neanderthals from Denisovans in the first place. This isn't a huge sample size, but was an obvious enough pattern to raise some intrigue.
Each of the points is a different Neanderthal. Keep in mind the standard errors of this graph mean top to bottom of y-axis is about 6 SE, and left to right of x-axis is about 7.5 SE.

I'd like to mention here the find of 5 graves from the bell beaker period (ca. 2.600 – 2.200 BC) in Bergrheinfeld, Bavaria, Germany. It was promised to investigate the DNA of these samples, the bones are said to be in good preservation conditions. The important fact is that we already have ancient DNA results from Bergrheinfeld for the corded ware period (ca. 3.000 – 2.200 BC) with the males being R1a so it will be exciting to compare with the bell beaker samples and give nice insights into the genetic change of these two cultures in Lower Franconia.
Can someone convert the BAM files of these two samples and sent them to Davidski?
They are from the already sampled Zhagunluke site but one has some kind of weird profile which seems 60-70% Steppe_MLBA and rest IAMC. He also is R1a-YP413 a clade rather common in Kurds, Balochs and Pashtuns and before not showing up in Xinjiang and Iron Age Steppe

This may also be why Neanderthals appeared closer to modern humans than Densivoans in previous studies. 700,000-500,000 ago is estimated split between common ancestor of AMH and Neanderthals/Denisovans. Neanderthal and Denisovans split right after that.

Is there coordinates or admixture results of this sample???
I just have some simulated coordinates based on the Harappa results. He is probably some high Steppe MLBA+IAMC/ANE mix so rather an early sample would be my guess. Doesn't look like some late IA Southeast Iranic too me.

When is this sample dated too ?? I think proper coordinates are needed but it has the same components as one of the other outliers in this cemetery , they plot very close on the PCA. The Steppe MLBA is more 35-40% but there is tonnes of excess ANE/Siberian type ancestry.
