Massive migration from the steppe was a source for Indo-European languages in Europe

We generated genome-wide data from 69 Europeans who lived between 8,000–3,000 years ago by enriching ancient DNA libraries for a target set of almost 400,000 polymorphisms. Enrichment of these positions decreases the sequencing required for genome-wide ancient DNA analysis by a median of around 250-fold, allowing us to study an order of magnitude more individuals than previous studies and to obtain new insights about the past. We show that the populations of Western and Far Eastern Europe followed opposite trajectories between 8,000–5,000 years ago. At the beginning of the Neolithic period in Europe, ∼8,000–7,000 years ago, closely related groups of early farmers appeared in Germany, Hungary and Spain, different from indigenous hunter-gatherers, whereas Russia was inhabited by a distinctive population of hunter-gatherers with high affinity to a ∼24,000-year-old Siberian. By ∼6,000–5,000 years ago, farmers throughout much of Europe had more hunter-gatherer ancestry than their predecessors, but in Russia, the Yamnaya steppe herders of this time were descended not only from the preceding eastern European hunter-gatherers, but also from a population of Near Eastern ancestry. Western and Eastern Europe came into contact ∼4,500 years ago, as the Late Neolithic Corded Ware people from Germany traced ∼75% of their ancestry to the Yamnaya, documenting a massive migration into the heartland of Europe from its eastern periphery. This steppe ancestry persisted in all sampled central Europeans until at least ∼3,000 years ago, and is ubiquitous in present-day Europeans. These results provide support for a steppe origin of at least some of the Indo-European languages of Europe.

Bell Beakers in the Southern Meseta of the Iberian Peninsula : Socioeconomic context and new data

An updated summary of the Bell Beaker problem in the Southern Meseta of the Iberian Peninsula is presented, following the great increase of new finds resulting from the latest surveys and excavations. Totalling 181 sites, this is one of the biggest concentrations of Beaker sites in Europe. High-quality information, however, is still restricted to the one extensively excavated and recently published site, the settlement of El Ventorro (Madrid). The available information is compared with that of the Northern Meseta, and a model is presented of the role Beakers played, as a ritual drinking-set, in the development of ranked societies in the inner regions of Iberia.
