Newgrange

    Remarkably, a local myth resonates with both the DNA results and the Newgrange solar phenomenon. The story was first recorded in the 11th Century AD - four millennia after the construction of Newgrange - and tells of a builder-king who restarted the daily solar cycle by sleeping with his sister.

    The Middle Irish place name for the neighbouring Dowth passage tomb, Fertae Chuile, is based on this lore and can be translated as "Hill of Sin".

    It’s a pity she didn’t go into more detail. Apparently the paper was involved in has been embargoed for a year or so. Interesting that this hierarchy was noted around this time, as another male dominated hierarchy came into being in the mid bronze age that carried into the Gaelic chieftan era.

    It has previously been hypothesized that the spread of agriculture into Britain and Ireland was assisted by pre-existing maritime connections that developed in the Mesolithic. However, our results suggest that, before the Neolithic, the Irish Sea posed a formidable barrier to gene flow. The genomes of Irish hunter-gatherers form a distinct cluster within a wider grouping of Mesolithic hunter-gatherers from northwest Europe, sharing excessive levels of drift with each other despite a separation of over half a millennium. By contrast, British hunter-gatherers show no differentiation from their continental contemporaries. This is consistent with palaeogeographic models that posit a Doggerland bridge between Britain and the continent for most of the Mesolithic, but a separation of Ireland that pre-dates the Holocene
    epoch.

    To our knowledge, Irish hunter-gatherers also exhibit the largest degree of short runs of homozygosity described for any ancient—or indeed modern—genome, a signature of ancestral constriction that supports a prolonged period of island isolation. This implies that continental and British hunter-gatherers lacked the technology or impetus required to maintain frequent contact with Ireland, and reflects the relatively late seaborne colonization of the island in the Mesolithic (approximately 8,000 bc), followed by a sharp divergence in lithic assemblages. Nonetheless, as there were no signatures of recent inbreeding, it appears Irish hunter-gatherers were capable of sustaining outbreeding networks within the island itself despite the estimated carrying capacity of only 3,000–10,000 individuals.

    Ultimately, Irish hunter-gatherers originate from sources who are related to individuals of the Upper Palaeolithic period from Italy, and show no evidence of contribution from an earlier western lineage that persisted in Spain. However, we detect a significant excess of this ancestry in a hunter-gatherer of the Mesolithic from Luxembourg relative to Irish and British hunter-gatherers (Supplementary Table 9), demonstrating the survival of this ancestry outside Iberia. We also explore the genetic legacy of Irish hunter-gatherers in the Neolithic population of the island, and discover an incidence of direct ancestral contribution. Within a broader pattern of high haplotypic affinities among European farmers to local hunter-gatherer groups, we uncover an outlier from Parknabinnia court tomb (designated PB675) who shows a disproportionate and specifically Irish hunter-gatherer contribution.

    The paper. My point was that the insights from the paper are not just Neolithic related
