The maternal genetic make-up of the Iberian Peninsula between the Neolithic and the Early Bronze Age
Anna Szécsényi-Nagy, Christina Roth, […]Kurt W. Alt

Abstract
"Agriculture first reached the Iberian Peninsula around 5700 BCE. However, little is known about the genetic structure and changes of prehistoric populations in different geographic areas of Iberia. In our study, we focus on the maternal genetic makeup of the Neolithic (~ 5500–3000 BCE), Chalcolithic (~ 3000–2200 BCE) and Early Bronze Age (~ 2200–1500 BCE). We report ancient mitochondrial DNA results of 213 individuals (151 HVS-I sequences) from the northeast, central, southeast and southwest regions and thus on the largest archaeogenetic dataset from the Peninsula to date. Similar to other parts of Europe, we observe a discontinuity between hunter-gatherers and the first farmers of the Neolithic. During the subsequent periods, we detect regional continuity of Early Neolithic lineages across Iberia, however the genetic contribution of hunter-gatherers is generally higher than in other parts of Europe and varies regionally. In contrast to ancient DNA findings from Central Europe, we do not observe a major turnover in the mtDNA record of the Iberian Late Chalcolithic and Early Bronze Age, suggesting that the population history of the Iberian Peninsula is distinct in character."

Abstract
Background
"The history of human populations occupying the plains and mountain ridges separating Europe from Asia has been eventful, as these natural obstacles were crossed westward by multiple waves of Turkic and Uralic-speaking migrants as well as eastward by Europeans. Unfortunately, the material records of history of this region are not dense enough to reconstruct details of population history. These considerations stimulate growing interest to obtain a genetic picture of the demographic history of migrations and admixture in Northern Eurasia."

Terminal Pleistocene Alaskan genome reveals first founding population of Native Americans

Reuther, Joel D. Irish, Ripan S. Malhi, Ludovic Orlando, Yun S. Song, Rasmus Nielsen, David J. Meltzer & Eske Willerslev

Abstract
"Despite broad agreement that the Americas were initially populated via Beringia, the land bridge that connected far northeast Asia with northwestern North America during the Pleistocene epoch, when and how the peopling of the Americas occurred remains unresolved1,2,3,4,5. Analyses of human remains from Late Pleistocene Alaska are important to resolving the timing and dispersal of these populations. The remains of two infants were recovered at Upward Sun River (USR), and have been dated to around 11.5 thousand years ago (ka)6. Here, by sequencing the USR1 genome to an average coverage of approximately 17 times, we show that USR1 is most closely related to Native Americans, but falls basal to all previously sequenced contemporary and ancient Native Americans1,7,8. As such, USR1 represents a distinct Ancient Beringian population. Using demographic modelling, we infer that the Ancient Beringian population and ancestors of other Native Americans descended from a single founding population that initially split from East Asians around 36 ± 1.5 ka, with gene flow persisting until around 25 ± 1.1 ka. Gene flow from ancient north Eurasians into all Native Americans took place 25–20 ka, with Ancient Beringians branching off around 22–18.1 ka. Our findings support a long-term genetic structure in ancestral Native Americans, consistent with the Beringian ‘standstill model’9. We show that the basal northern and southern Native American branches, to which all other Native Americans belong, diverged around 17.5–14.6 ka, and that this probably occurred south of the North American ice sheets. We also show that after 11.5 ka, some of the northern Native American populations received gene flow from a Siberian population most closely related to Koryaks, but not Palaeo-Eskimos1, Inuits or Kets10, and that Native American gene flow into Inuits was through northern and not southern Native American groups1. Our findings further suggest that the far-northern North American presence of northern Native Americans is from a back migration that replaced or absorbed the initial founding population of Ancient "

Turkish scientists to crack Neolithic-era DNA code, European funding awarded

"The European Research Council (ERC) has awarded Turkish scientists a €2.5 million ($2.9 million) grant to analyze the DNA of 1,500 people who used to live in the Anatolian region – the Asian part of present-day Turkey – during the Neolithic period."

It's incredible! Anatolia has been largely tested for the aDNA, and Italy only for 6 samples! Anyway, if results will be controlled from other researchers, we are glad that other data from Anatolia will come out... and that they say what came up there from European hunter-gatherers and what from Near-Eastern and Iranian ones...

They are putting a lot of money and effort into this project. Is it really about the Anatolian PIE language origin theory?!!

I cannot understand as to how tests of people from 12000 to 9000 years ago may shed some light upon the origin of the Indo-European languages. We are in a pure madness, and I'd want to know who in Europe promoted that funding, very likely the same gang of what Genetiker calls the "anti-white" geneticists whose name you should know very well. Of course Anatolia belongs to the European world, but here the Levantinists are always hoping to find up there some R1b1 ancestor, not found so far, and without testing Italy and nearby we wont be able to know from where some hgs found in Anatolia in the past did come. I said that R1 and K1 for the mt were in the European hunter-gatherers (and also Mathieson et al. said that), and I think that by testing Italy we could know more also about yHG J and even G etc.

Why are they wasting money on the first farmers? We know for a fact that there was no massive invasion of R1b-L151 from Anatolia in the Neolithic nor R1b-L151 from the Steppe in the BA. We do know that 50% of males in western Europe today are descended from only one man, Mr. R1b-L151.

Italy, Austria ,Belgium and France are the places that they should be doing lots of ancient dna testing in to find out more about the western/central European Mesolthic, Neolithic and the BA.

A poster writes;
"Great Western European R1b That Conquered the World.."LOL

The I haplogroup became the dominant male group in the European Mesolithic. The G haplogroup became the dominant male group in the European Neolithic. R1b haplogroup became the dominant male group in the BA and still is. That is not to say that the other groups were not living in Europe in those periods and they still are. All of these groups have been in Europe for at least 13,000 years.
