On the upper reaches of the Tigris and Euphrates, archaeologists encounter evidence that challenges conventional understandings of early state formation as a transition from ‘small-scale, egalitarian’ to ‘large- scale, stratified’ societies. One such location is the Early Bronze Age cemetery of Başur Höyük, which presents evidence of grand funerary rituals—including ‘retainer burials’ and spectacular deposits of metallic wealth—in an otherwise small-scale, egalitarian setting. A further, puzzling feature of this cemetery is the preponderance of teenagers in the richest tombs. Here we describe the combined results of archaeological and anthropological analysis at Başur Höyük, including ancient DNA, and consider the challenges they pose to traditional accounts of early state formation.

Given it's archaeological culture, given that it's low coverage and it's date it is more likely that it was V1636.
Basur Hoyuk has similar features to Arslantepe region.
No single Z2110 was found in ancient Armenia. Z2110 is more popular in Balkans.
We are always going to have surprises in the South of the Caucasus and Iran
Başur Höyük is too southern and too ancient, can be an indication of Southern R1b-Z2103 clades movements from the South to the North of the Caucasus with the local CHG components.
Başur Höyük is related to Arslantepe and archaeological evidence indicates clear connections with the Maikop-Novosvobodnaya kurgans culture:

This was posted to X a little while ago. I was under the impression that steppe ancestry arrived a bit later this far south, no? All of the modern populations at top have steppe ancestry, albeit limited.

It's circulating on twitter. I don't know who converted it, perhaps it's just simulated and given its low coverage it's probably not very reliable. I'd rather wait for the study to be published, just quickly checked them.
Vlad:
Yeah, using more proximate sources the samples prefer Maykop in the models (Same goes for some Arslan Tepe Chalcolithic samples). With those sources PB710 gets even a few percent Yamnaya or other Steppe BA source, but I'm not convinced it's real.

That's not from me but I can say that's because, contrary to usual practice, they didn't remove the adapters. So before attempting to map, you have to remove them with trimmomatic (truseq3 option) or fastp.

do these adapters inflate African admixture/noise in a sample?

I don't think it should, but I have never investigated that
