    I think not yet. The article is based on a conference presentation, not on a published paper.

    Question: what happened to Dzudzuana paper? The preprint was posted in (googles) 2018 and there is still not published paper.

    The Secrets of Ancient Thessaloniki: Analysis of 4,500 Skeletons
    During the construction of the Thessaloniki Metro, excavations of two ancient cemeteries revealed thousands of skeletons. These archaeological treasures were transferred to the Laboratory of Natural Anthropology in Komotini for in-depth study.

    Here's a Youtube video of the scientists involved (some of whom are people who worked on the Aegean Palatial paper) talking about the project:


    I've criticized the Greek labs before for some shoddy conclusions, but this is a goldmine of samples so I don't really care what they say about them as long as they make the samples available.
    4500?!?!

    Probably too much to hope that they all were sequenced. That would be major. Probably going to ne a small number though.

    In Europe the spectre of nomads from the steppes invokes an image of mass migration by a faceless horde of savage warriors. Western archaeologists abandoned the faceless migrating horde decades ago as a usually imaginary and substantively worthless explanation for culture change, but Marija Gimbutas’s conception of the Kurgan Culture kept this image alive in archaeological debates about Late Neolithic cultural shifts long after it had disappeared in other contexts. Recent studies of ancient DNA revealed large-scale, long-distance migrations from the steppes in the Late Neolithic/Early Bronze Age that have prompted some to ask the uneasy question of whether Gimbutas was right. This essay places the recent DNA discoveries and the debate about nomads from the steppes in its historical context; and pleads for a processual approach to migration quite different from the single-event, conquest model of Gimbutas.
    Wonderful and excellent article, recommend all to read in full.

    Anyone see what the modern human mt-haplogroups were for the IUP samples? Was there enough resolution to determine that?

    For the remaining 171 samples, we assigned mtDNA fragments to specific hominin groups by counting the number of fragments that support lineage-specific states at diagnostic sites that distinguish between modern human, Neanderthal and Denisovan mtDNA genomes. We distinguished three Neanderthal lineages: the Sima de los Huesos lineage (representing Neanderthals who lived approximately 430 ka in Spain and whose mtDNA is most closely related to that of Denisovans)18,19; the Hohlenstein–Stadel (HST) lineage, which falls basal to all other Neanderthal mtDNAs20; and the ‘typical’ Neanderthal mtDNA, known from all other Neanderthals. The presence of ancient modern human mtDNA was evaluated by restricting the analysis to deaminated fragments to mitigate the effect of present-day human DNA contamination. We identified Denisovan and typical Neanderthal mtDNA in 79 and 47 samples, respectively (based on 54–9,093 unique hominin mtDNA fragments), and modern human mtDNA in 35 samples (based on 55–2,200 deaminated fragments) (Fig. 1a–c, Extended Data Fig. 3a, b). We detected DNA from two hominin groups in ten samples, either within a single library or across libraries that were prepared from independent subsamples in some cases (Extended Data Fig. 6c, Supplementary Information section 4). In addition, we identified one sample (M76 from Main Chamber (layer 20)) containing hominin mtDNA fragments that support the branch shared by HST and typical Neanderthal mtDNA, but neither of the branches defining those lineages. This signal cannot be created by mixing mtDNA fragments from Neanderthals, Denisovans and ancient or present-day modern humans. On the basis of simulations with ancestralized Neanderthal mtDNA, the mtDNA in this sample is compatible with the presence of a previously unknown Neanderthal mtDNA lineage that diverged from typical Neanderthal mtDNA between 255 and 230 ka, 20 to 45 thousand years after the split of the HST and typical Neanderthal mtDNA lineages (Supplementary Information section 9).
    the Sima de los Huesos mtDNA lineage===>Denisovan mtDNA lineage===>Neanderthal mtDNA lineage===>African modern human mtDNA lineage===>OOA modern human mtDNA lineage

    Were there coexistence of ancient and modern lineages in some place some time common phenomena?
