    The Genetics of Battle Ax Culture

    It's a subset of Corded Ware, of course.

    See:

    "https://royalsocietypublishing.org/d...rspb.2019.1528

    "The Neolithic period is characterized by major cultural transformations and human migrations, with lasting effects across Europe. To understand the population dynamics in Neolithic Scandinavia and the Baltic Sea area, we investigate the genomes of individuals associated with the Battle Axe Culture (BAC), a Middle Neolithic complex in Scandinavia resembling the continental Corded Ware Culture (CWC). We sequenced 11 individuals (dated to 3330–1665 calibrated before common era (cal BCE)) from modern-day Sweden, Estonia, and Poland to 0.26–3.24× coverage. Three of the individuals were from CWC contexts and two from the central-Swedish BAC burial ‘Bergsgraven’. By analysing these genomes together with the previously published data, we show that the BAC represents a group different from other Neolithic populations in Scandinavia, revealing stratification among cultural groups. Similar to continental CWC, the BAC-associated individuals display ancestry from the Pontic–Caspian steppe herders, as well as smaller components originating from hunter–gatherers and Early Neolithic farmers. Thus, the steppe ancestry seen in these Scandinavian BAC individuals can be explained only by migration into Scandinavia. Furthermore, we highlight the reuse of megalithic tombs of the earlier Funnel Beaker Culture (FBC) by people related to BAC. The BAC groups likely mixed with resident middle Neolithic farmers (e.g. FBC) without substantial contributions from Neolithic foragers."

    it confirms what Mittnik already showed : early CWC were 100 % Yamna, only later they admixed with EEF

    as for FBC, all samples are from the megalithic era, hence Y-DNA I2
    early FBC could have been different, G2a maybe

    I don't see anything new in terms of the uniparentals.

    "The individuals from BAC and CWC contexts, including oll007 from a megalithic burial, displayed U4 and U5 mitochondrial DNA (mtDNA) lineages, previously associated with Stone Age hunter–gatherers [2934], and H1, N1a, and U3 lineages, associated with Neolithic farmers [1,32,35,36] (table 1; electronic supplementary material, table S4). This broadly coincides with the wide variety of mtDNA lineages found in other individuals from CWC contexts (e.g. [2,32]). However, the U3 and N1a lineages, which were found here (poz44 and ber2), have not been reported from individuals excavated in CWC contexts. The two males in our dataset (ber1 and poz81) belonged to Y-chromosome R1a haplogroups (table 1; electronic supplementary material, table S5), as do the majority of males (16/24) from the previously published CWC contexts (Viby in Sweden, Ardu and Kunila in Estonia, Gyvakarai and Spiginas in Lithuania, Bergrheinfeld and Esperstedt in Germany, and Brandýsek in the Czech Republic) [1,2,7,31,32,37], while a smaller fraction belonged to R1b [3/24] or I2a [3/24] lineages (Tiefbrunn and Esperstedt in Germany, Pikutkowo and Łęki Małe in Poland, and Brandýsek in the Czech Republic) [2,23,32,37]. The R1a haplogroup has not been found among Neolithic farmer populations nor in hunter–gatherer groups in central and western Europe, but it has been reported from eastern European hunter–gatherers and Eneolithic groups [1,31,32]. Individuals from the Pontic–Caspian steppe, associated with the Yamnaya Culture, carry mostly R1b and not R1a haplotypes [1,2,31,32].Three individuals had enough data for investigating the LCT gene-region (electronic supplementary material, table S6), and one of these individuals (kar1) carried at least one allele (-13910 C->T) associated with lactose tolerance, while the other two individuals (ber1 and poz81) carried at least one ancestral variant each, consistent with previous observations of low levels of lactose tolerance variants in the Neolithic [1,2,33,38] and a slight increase among individuals from CWC contexts [32]. The individuals further displayed a mixed appearance with both light and dark hair and brown and blue eyes (electronic supplementary material, table S6). Stable carbon and nitrogen isotope values for the individuals from modern-day Sweden show a terrestrial diet except for the Ajvide individual (electronic supplementary material, table S1 and figure S3). Strontium isotope data for the two individuals in Bergsgraven have differing signals, indicating recent migration of at least one of the individuals to the area (electronic supplementary material, table S2 and figure S4)."

    @Bicicleur.
    I don't know if this shows Corded Ware were all identical to Yamnaya, although there was some overlap.

    I agree, though, nothing new here that I can see.

    the oldest known CWC sample (Mittnik), 3000 BC in Estonia (or Latvia?) had 0% EEF and a typical Yamna EHG-CHG mix
    somehow the oldest generation of CWC was whiped out by the 2nd generation, who had gotten admixed with EEF
    my guess is that the plague had something to do with it
    the oldest generation didn't have any immunity, those admixed with EEF had gained immunity and spread the plague toward eastern Europe
    we know there was plague in FBC 5 ka GÖkhem passage grave

    as you can see :
    3000 BC no LBK, all Yamna
    2200 BC some 25 % LBK

    they did not marry the local HG, just farmers, and they were not in Eastern Europe, so those in the east came from west, whiping out those without admix

    Good to confirm what we thought with more data.

    I bet the chances are good that Ros5 labeled IJ* will be pre-I1 if some experts analyzed the data.

    TRB spread some 6,3 ka, it's origin would be a merger between farmers and HG between lower Elbe and middle Vistula
    If this is true, then the HG would have been I1

    around 5,9 ka megalithic farmers arived in Denmark and overwhelmed the original TRB farmers
    their pottery remained TRB style, but with more decoration

    I2a1-P37>M423>Y3104>L161.1>S2639>L1498>Y3749>pre-S2742 is a typical megalithic clade, it's origin is in MN Iberia - the Alentejo high plain 7,5 ka
    so far all Y-DNA of TRB has been I2a, no G2a has been found in TRB except for Salzmünde, Germany
    this I1 would be the 2nd non-I2a
