    Copper Age-Bronze Age transition in southern Iberia

    1. The samples are out, but the paper is not, so no reference to where the samples are from, their age etc.
    2. Below I took a first stab at R1b versus non-R1b, so don't take these as final. Even that took 4 hours of my weekend, so I will not be looking at the in any more detail in the foreseeable future.
    3. Obviously the massive founder effect they mention in the abstract is R-DF27 > Z195

    Genomic transformation and social organization during the Copper Age-Bronze Age transition in southern Iberia
    https://www.ebi.ac.uk/ena/browser/vi...907?show=reads

    Abstract: The emerging Bronze Age (BA) of southeastern Iberia saw dramatic social changes. Late Copper Age (CA) settlements were abandoned in favor of hilltop sites, and collective graves were largely replaced by single or double burials with often distinctive grave goods indirectly reflecting a hierarchical social organization, as exemplified by the BA El Argar group. We explored this transition from a genomic viewpoint by tripling the amount of data available for this period. Concomitant with the rise of El Argar starting ~2200 cal BCE, we observe a complete turnover of Y-chromosome lineages along with the arrival of Steppe-related ancestry. This pattern is consistent with a founder effect in male lineages, supported by our finding that males shared more relatives at sites than females. However, simple two-source models do not find support in some El Argar groups, suggesting additional genetic contributions from the Mediterranean that could predate the Bronze Age.

    THE POPULATION GROUP OF CALLE DINAMARCA (VALENCINA DE LA CONCEPCION). A
    SOCIOCULTURAL AND ARCHAEOMETRIC APPROACH
    Abstract author(s): Morillo León, José Miguel (Institut für Ur- und Frühgeschichte/Christian-Albrechts-Universität zu Kiel) - Pajuelo
    Pando, Ana - López Aldana, Pedro (HUM949. Grupo de Investigación Tellus. Prehistoria y Arqueología en el sur de Iberia Departamento
    de Prehistoria y Arqueología) - Gavilán Zaldúa, Maria - Serrano Castilla, Beatriz - Rojas Aledo, Violeta (Independent)
    Abstract format: Oral
    During the excavation of a plot in the emblematic site of Valencina de la Concepción in 2009, a group of three sepulchres belonging
    to an early phase of this site were discovered. The archaeological excavation was conducted up to the levels reached by the
    construction pro ject, uncovering approximately 100 individuals, of which up to a minimum of 68 were recovered. The funerary
    structures discovered consisted in two hypogea and one funerary pit, and the human remains were extracted with the sediment
    attached, consolidated using paraloid.
    Approximately ten years after, 44 of the skulls were selected to sample them for genetic and isotopic characterization in the framework
    of the European Project Towards a New European Prehistory.
    The chance of studying a coherent social group that undoubtedly shared a sort of link offered relevant perspectives in terms of
    kinship and social relations within the members of a subsidiary group, in the context of Chalcolithic site characterized by its own
    social complexity. Even more, during the microexcavation of the skulls prior their sampling, 18 individuals showed diverse grades of
    traumas.

    The site is in SW Spain and it would aid to get a better picture about what was happenning in such period (3200 to 2300).

    I'd love to see the mtDNA reads, if you could work your magic on that too.

    Well, E1b1b among Bell Beakers:
    BAS002 = P312+
    BAS018 = P312+
    BAS022 = P312+
    BAS023 = P312+
    BAS024 = P312+
    BAS025 = E1b1b1a1b1
    BAS026 = P312+
    What is BAS standing for? Could he be E-V13 or is he just a survivor of an older lineage of E-L618?

    Thank you!

    If he is not E-V13, I think the most likely scenario is that he was picked up on the way by steppe groups, probably from those Neolithics which carried, which is true all the way from the Ukraine to Iberia, because in all those regions were Neolithic inhabitants with E1b1b, from East to West: Tripolye-Cucuteni - Lengyel-Sopot - Michelsberger - ICW remains in Iberia.
    If he has significant North African ancestry other BB don't have, that would change it of course.

    This just adds up on the diversity of E-L618+ samples in Europe which so far haven't been found outside Europe so there isn't any suspicion why this one should have significant North African ancestry. Also, there is that Neolithic V13+ sample, fully EEF like from Iberia, much older than this sample, so again, there isn't any reason to suspect North African ancestry.
    Then again, we should see the auDna picture to put the things in context but I believe this sample would either be fully EEF like or a two way mix between EEF and Steppe.
    It could also be native to Iberia having in mind that the Cardium Pottery culture was spread in Iberia as well and having in mind that V13+ sample again.
    Either way, his EEF ancestry is far more likely to have been derived fully from the farmers who came through the Levant and Anatolia rather than to any Ibero-Maurusian ancestry which so far haven't been found in any significant numbers in Europe.
    Nonetheless, a dead end lineage...

    I guess BAS might stand for La bastida de Totana. It seems he is indeed L618, but negative for all known subbranches. This could point to a neolithic clade, which could have arrived with cardial ware.

    Seems an E1b-L618 basically like that of HRV_Cardial_N:I3948 , similar derived mutations, similar ancestral ones at each site covered in both, hence neolithic. Ave07 from neolithic northeast Spain did have L618 too, though it's an old-ish study.
