    “Then 4,500 years ago the Beaker people arrived in Britain and Ireland. These people seem to be genetically very similar to modern Irish and brought a unique culture defined by beaker-shaped vessels.
    We also discussed controversies such as the timing of the arrival of the Irish language, and the patterns of interaction across the Atlantic facade, of which Ireland was part (which resulted in features such as the spread of Megalith culture to Ireland from the mainland.”

    Ancient DNA is a powerful tool for studying the past – when archaeologists and geneticists work together

    DNA has moved beyond esoteric science and into the center of everyday conversations about identity, culture and politics. It’s also reshaping stories about the past as advances allow scientists to extract ancient DNA (aDNA) from skeletons found at archaeological sites.

    With each ancient genetic sequence, scientists learn new information about how people moved around and interacted in the ancient world. In some cases, this has helped overturn theories and resolve age-old debates.

    But the aDNA “revolution” has also caused friction among geneticists, archaeologists and others over how this research is done. As archaeologists who collaborate on aDNA projects, we’ve witnessed these tensions firsthand. What lies at the heart of this rift, and how can these disciplines work together to better research humanity’s past?

    .....
    Communication and cooperation go a long way, but fixing the system ultimately requires a shift in how science is funded and rewarded. And the public has a key role to play as the taxpayers who fund scientific research and consume its findings. A scientifically literate society can demand work that meets ethical guidelines and provides meaningful insights about our past. Together, scientists and the public can set the tone for what aDNA research becomes and how we use it to explore our shared human heritage.

    We performed Y-chromosome haplogroup determination (Table S4) using the nomenclature of the International Society of Genetic Genealogy (http://www.isogg.org) version 11.110 (21 April 2016). We restricted to sequences with mapping quality ≥ 30 and bases with quality ≥ 30.
    We comment here on the striking Y-chromosome patterns observed during the Copper Age-Bronze Age transition in Iberia. All the Bronze Age males from Iberia with sufficient coverage (n=30) belonged to R1b-M269 (R1b1a1a2). Furthermore, all the R1b-M269 males with sufficient coverage (n=15) could be further classified as R1b-P312 (R1b1a1a2a1a2). Only one Bronze Age male, esp005.SG (7), had DNA sequences overlapping R1b-DF27 (R1b1a1a2a1a2a) and he was positive for the mutation. Two Bronze Age males, I6470 and I3997, had DNA sequences overlapping R1b-Z195 (R1b1a1a2a1a2a1), with I6470 being negative and I3997 positive. Eleven Bronze Age males had DNA sequences overlapping R1b-Z225 (R1b1a1a2a1a2a5), with only VAD001 being positive for the mutation (one Iron Age male, I3320, is also positive for this mutation). We thus detect three Bronze Age males who belonged to DF27 (154, 155), confirming its presence in Bronze Age Iberia. The other Iberian Bronze Age males could belong to DF27 as well, but the extremely low recovery rate of this SNP in our dataset prevented us to study its true distribution. All the Iberian Bronze Age males with overlapping sequences at R1b-L21 were negative for this mutation. Therefore, we can rule out Britain as a plausible proximate origin since contemporaneous British males are derived for the L21 subtype.

    Very interesting. My maternal grandfather, whose paternal line comes from Portugal, belonged to a clade of R1b-Z225!

    In this article, Villalba-Mouco et al. report new genomic data from the Iberian Peninsula. Iberian hunter-gatherers show dual Late Pleistocene genetic ancestry as a result of the admixture from different refugia. This mixed Late Pleistocene ancestry can be traced in the Iberian Neolithic farmers.

    Doctors Julian Reed and Barbara Sullivan, fall in love with each other and with the idea of cloning a Neanderthal from ancient DNA. Against the express directive of University administrators they follow through on this audacious idea. The result is William: the first Neanderthal to walk the earth for some 35,000 years. William tries his best to fit into the world around him. But his distinctive physical features and his unique way of thinking--his "otherness"--set him apart. William's story is powerful and unique, but his struggle to find love and assert his own identity in a hostile world is universal -- and timeless. William is directed by producer / filmmaker Tim Disney, of the films A Question of Faith, Tempesta, and American Violet previously. The screenplay is written by J.T. Allen and Tim Disney. Dada Films will release Disney's William in select theaters starting April 12th this spring. For more, visit the film's official website.

    Abstract

    The Canary Islands’ indigenous people have been the subject of substantial archaeological, anthropological, linguistic and genetic research pointing to a most probable North African Berber source. However, neither agreement about the exact point of origin nor a model for the indigenous colonization of the islands has been established. To shed light on these questions, we analyzed 48 ancient mitogenomes from 25 archaeological sites from the seven main islands. Most lineages observed in the ancient samples have a Mediterranean distribution, and belong to lineages associated with the Neolithic expansion in the Near East and Europe (T2c, J2a, X3a…). This phylogeographic analysis of Canarian ancient mitogenomes, the first of its kind, shows that some lineages are restricted to Central North Africa (H1cf, J2a2d and T2c1d3), while others have a wider distribution, including both West and Central North Africa, and, in some cases, Europe and the Near East (U6a1a1, U6a7a1, U6b, X3a, U6c1). In addition, we identify four new Canarian-specific lineages (H1e1a9, H4a1e, J2a2d1a and L3b1a12) whose coalescence dates correlate with the estimated time for the colonization of the islands (1st millennia CE). Additionally, we observe an asymmetrical distribution of mtDNA haplogroups in the ancient population, with certain haplogroups appearing more frequently in the islands closer to the continent. This reinforces results based on modern mtDNA and Y-chromosome data, and archaeological evidence suggesting the existence of two distinct migrations. Comparisons between insular populations show that some populations had high genetic diversity, while others were probably affected by genetic drift and/or bottlenecks. In spite of observing interinsular differences in the survival of indigenous lineages, modern populations, with the sole exception of La Gomera, are homogenous across the islands, supporting the theory of extensive human mobility after the European conquest.

    Anatolia was home to some of the earliest farming communities. It has been long debated whether a migration of farming groups introduced agriculture to central Anatolia. Here, we report the first genome-wide data from a 15,000-year-old Anatolian hunter-gatherer and from seven Anatolian and Levantine early farmers. We find high genetic continuity (~80–90%) between the hunter-gatherers and early farmers of Anatolia and detect two distinct incoming ancestries: an early Iranian/Caucasus related one and a later one linked to the ancient Levant. Finally, we observe a genetic link between southern Europe and the Near East predating 15,000 years ago. Our results suggest a limited role of human migration in the emergence of agriculture in central Anatolia.
    The Anatolian Hunter Gatherer paper is out.
