    Default The Population Genomics Of Archaeological Transition In West Iberia

    Abstract

    We analyse new genomic data (0.05-2.95x) from 14 ancient individuals from Portugal distributed from the Middle Neolithic (4200-3500 BC) to the Middle Bronze Age (1740-1430 BC) and impute genomewide diploid genotypes in these together with published ancient Eurasians. While discontinuity is evident in the transition to agriculture across the region, sensitive haplotype-based analyses suggest a significant degree of local hunter-gatherer contribution to later Iberian Neolithic populations. A more subtle genetic influx is also apparent in the Bronze Age, detectable from analyses including haplotype sharing with both ancient and modern genomes, D-statistics and Y-chromosome lineages. However, the limited nature of this introgression contrasts with the major Steppe migration turnovers within third Millennium northern Europe and echoes the survival of non-Indo-European language in Iberia. Changes in genomic estimates of individual height across Europe are also associated with these major cultural transitions, and ancestral components continue to correlate with modern differences in stature.
    The paper by Rui Martiniano at el. is here.





    Does anyone know what kind of nomenclature they are using? It doesn't seem to be the newest one as I doubt they found R1b-V88 in Bronze Age Iberia.

    The authors of the paper state that:

    Strikingly, the array of Y-chromosome haplotypes in ancient Iberia shifts from those
    typical of Neolithic populations to haplogroup R1b-M269 in each of the three BA males.
    Interestingly, modern Basque populations have this variant at high frequency (87.1%)
    ... so it seems they found "regular" R1b-M269.

    If these Bronze Age M269s introgressed from the East, then it seems that its Caucasus component got dilluted to zero by the time these men reached Portugal:

    So has it been concluded then, that R1b-V88 didn't reach Africa through Iberia?

    In fact, they are not even the Europeans in strict sense, meaning European as in bearing the responsibility and understanding of European interests. Poland has always been an subordinate country, on one side sucking German dick, on the other side -- Russian one, some kind of "novice" europeans, who are full of inferiority complexes, hysteria and obsessity neuroses. This is also true for all Baltic countries

    African V88 coalesces with Sardinian V88 ~7-8kya which diverged from other Eurasian populations over 9Kya... This is basic shit.
