I agree. Technically we could find the source populations, through times and places, to mix and receive something similar to these guys. In real life however, to get them to Balkans in their pure state to make children is impossible. Heck, it would be a miracle to get one of them happen, but 4 weird genomes within few hundred years, impossible. It would require a big tribe scale of migrations through thousands of miles, different climatic zones and food source of these hunter gatherers of Siberian, NE Asian, San, W Africans, and time travel of Neolithic Levant, in few generations to get to Bulgaria in same time period.Bulgaria has long been at the receiving end of migrations from the Eurasian Steppe, and that occasionally included people from the Altai and Mongolia, but also from various parts of Siberia (e.g. the Uralic Magyars).
What is more surprising in that Bulgaria IA sample with 42% of Siberian is the rest of the admixtures.
First of all, that sample completely lacks NE European (i.e. also Indo-European) admixture. What kind of population in Europe, Central Asia or the northern Middle East still lacked any NE European admixture (I mean not even 0.1%) around 800 BCE? Even Chalcolithic and EBA Anatolians and Caucasians had clearly noticeable levels of NE European admixture.
Then, other LBA and A Bulgarian samples have no SW Asian, except one that has 1.9%. But this one has 10.2%! I suppose there is no need to say that Southwest Asia isn't one the way between Mongolia and Bulgaria, and that no population in the middle has any considerable SW Asian admixture. If we exclude the 42% NE Asian from the genome, a few generations ago the non-Mongoloid ancestors of that person could have carried nearly 20% of SW Asian, 15% of Baloch/Gedrosian and 65% of Mediterranean. The problem is that there isn't any population with that kind of admixture. The closest would be North Africans (esp. Tunisians), but with East African instead of Baloch. Maybe we should assume that the Baloch came together with the Siberian, as the total is close to 50%.
I looked up the HarappaWorld K=16 admixture for worldwide populations (if you click on the admixture's name the listing get sorted by frequency) and the closest to pure Siberian without NE Asian are the Nganasans (89%), who live in the Krasnoyarsk Krai in Central Siberia. They do have a bit of Baloch and Beringian. Actually let's assume that this sample is a first generation hybrid. One parent would have contributed 43.6 Siberian, 6% Baloch and 0.4% Beringian, and the other parent 37.6% Mediterranean, 10.2% SW Asian and 2.2% Baloch.
In that case the second parent would be much closer to a pure European Neolithic farmer with 20% of SW Asian admixture, so more like a Levantine farmer, but with only a little Baloch/Gedrosian and no NE_Euro admixture at all. How is that possible in Iron Age Bulgaria is a mystery to me. I can understand that some Siberian tribe migrate toward the Balkans from time to time. Here considering that the individual is female and carries mt-haplogroup HV, the mother would have been the one of Middle Eastern and the father of Siberian origin. That makes sense. The invader are typically men who take local brides. In that case the local bride would have either recently arrived from the South Levant or lived in a sort of time warp since the Late Neolithic, immune to the 3400 years of Indo-European presence in the Balkans by 800 BCE.
There is something wrong with these samples for sure, but I don't know what yet.
