    Heterogeneous Hunter-Gatherer and Steppe-Related Ancestries in France

    Highlights

    Sequencing of 24 human genomes from France dated to ∼3,400–1,600 cal. years BCE

    These genomes show heterogeneous hunter-gatherer and steppe-related ancestries

    Paris Basin Neolithic and Mesolithic groups admixed as recently as ∼3,800 years BCE

    Admixture with steppe herders in southern France dated as early as ∼2,650 years BCE
    Summary
    The transition from the Late Neolithic to the Bronze Age has witnessed important population and societal changes in western Europe.1 These include massive genomic contributions of pastoralist herders originating from the Pontic-Caspian steppes2,3 into local populations, resulting from complex interactions between collapsing hunter-gatherers and expanding farmers of Anatolian ancestry.4, 5, 6, 7, 8 This transition is documented through extensive ancient genomic data from present-day Britain,9,10 Ireland,11,12 Iberia,13 Mediterranean islands,14,15 and Germany.8 It remains, however, largely overlooked in France, where most focus has been on the Middle Neolithic (n = 63),8,9,16 with the exception of one Late Neolithic genome sequenced at 0.05× coverage.16 This leaves the key transitional period covering ∼3,400–2,700 cal. years (calibrated years) BCE genetically unsampled and thus the exact time frame of hunter-gatherer persistence and arrival of steppe migrations unknown. To remediate this, we sequenced 24 ancient human genomes from France spanning ∼3,400–1,600 cal. years BCE. This reveals Late Neolithic populations that are genetically diverse and include individuals with dark skin, hair, and eyes. We detect heterogeneous hunter-gatherer ancestries within Late Neolithic communities, reaching up to ∼63.3% in some individuals, and variable genetic contributions of steppe herders in Bell Beaker populations. We provide an estimate as late as ∼3,800 years BCE for the admixture between Neolithic and Mesolithic populations and as early as ∼2,650 years BCE for the arrival of steppe-related ancestry. The genomic heterogeneity characterized underlines the complex history of human interactions even at the local scale.

    It confirms even further to me that people should stop drawing conclusions from singular samples when it comes to what people of some specific archeological group were like etc.

    Yeah, it must be collected from different sources.

    This sample GBVGK is (Iberian Influence Bell Beaker) R1b-DF27-Z195.

    From the previous paper on France, Ancient genomes from present-day France unveil 7,000 years of its demographic history.

    https://www.pnas.org/content/117/23/...PKg-Sw1vjzLLgA

    PIR3037AB, About 40 miles SW of Montpellier, close to Narbonne, the culture is simply described as early bronze age and he's dated 2195-1922 BC, he is R1b-L21-DF21

    So we have two branches of R1b-P312 in the same locality.

    Narbonne was at a crossroads of the Bell Beaker and Celtic world positioned on a strategic Warrior Stelae Trail between SW Iberia, the Alps (Sion) and the Steppes.

    https://www.academia.edu/8299894/Ind...ter_prehistory

    https://pin.it/4AnzKSn

    The Mediterranean to Atlantic route via Narbonne, the Aude River Valley, Carcassonne, Toulouse, The Garonne River Valley and the Atlantic at Bordeaux.

    Robb Graham claims the Via Herkales preceded the Roman Via Domita. Strabo states that the Celtae were a tribe living around Narbonne.

    Well it's Z195, and arguably the oldest one of those currently identified. But the sample is GBVPK; and "Iberian influence" is in the eye of the beholder.

    Some of us have been suggesting for most of a decade that this haplogroup, in the date range suggested by the paper's authors, would be on its way to Iberia. Ancient DF27 in Narbonne, Sicily, Alsace, Elbe valley, etc. can't be influenced by Iberia until it has gotten there, and "refluxed." If that even happened.

    We are also discussing this sample, and paper, here: https://anthrogenica.com/showthread....l=1#post736488

    Please explain to me why you are calling GBVPK "Iberian Influence Bell Beaker".

    I see him referred to as having "an excess of Yamnaya_Samara ancestry", but I don't see the "Iberian Influence" part.

    Maybe I missed that, though, and you can enlighten me.

    Grotte Basse de la Vigne Perdue
    Also known as Grotte du Ruisseau (lat. 43.149150, long. 3.060582), the Grotte Basse de la Vigne Perdue cave is located on the right bank of an intermittent torrent (‘Rec de la Vigne Perdue’). This 4.10-m-long cave is subdivided in two chambers of 2.25 and 2.85 m wide. The entrance was obstructed by limestone blocks92. During the excavation in 1920, Theophile and Philippe Helena estimated the minimum number of individuals at 24 (20 adults and 4 children)93. In the second chamber, bones appeared grouped in several heaps, each covered by a stone mound. Archaeological material is characteristic of the Late Neolithic and the Early-Middle Bronze Age17. In particular hemispherical V-perforated buttons could be attributed to early Bell Beakers (Iberic influence). Two pottery frag- ments of the later Pyrenean style, as well as turtle-shaped V-perforated buttons were also present. Two double-ended copper awls of square cross-section and one barbed-and-tanged arrowhead could be attributed to any of these two early Bell Beaker phases.
    Based on the radiocarbon dates presented here, individual GBVPL (2,574-2,473 cal. years BCE) corresponds to the classical phase of the Veraza culture, and could be contemporaneous with the first intrusions of early Bell Beakers. The individual GBVPK (2,461-2,299 cal. years BCE) is included in the late Bell Beaker timing period (Pyrenean). The individual GBVPO was dated to the mid- dle Bronze Age (1,737-1,547 cal. years BCE), consistent with the presence in the burial of several bell-shaped cups, including one with an ‘ad ascia’ handle
