AbstractFarming was first introduced to southeastern Europe in the mid-7thmillennium BCE – brought by migrants from Anatolia who settled in the region before spreading throughout Europe. To clarify the dynamics of the interaction between the first farmers and indigenous hunter-gatherers where they first met, we analyze genome-wide ancient DNA data from 223 individuals who lived in southeastern Europe and surrounding regions between 12,000 and 500 BCE. We document previously uncharacterized genetic structure, showing a West-East cline of ancestry in hunter-gatherers, and show that some Aegean farmers had ancestry from a different lineage than the northwestern Anatolian lineage that formed the overwhelming ancestry of other European farmers. We show that the first farmers of northern and western Europe passed through southeastern Europe with limited admixture with local hunter-gatherers, but that some groups mixed extensively, with relatively sex-balanced admixture compared to the male-biased hunter-gatherer admixture that prevailed later in the North and West. Southeastern Europe continued to be a nexus between East and West after farming arrived, with intermittent genetic contact from the Steppe up to 2,000 years before the migration that replaced much of northern Europe’s population.

AbstractRecent advances in sequencing techniques provide means to access direct genetic snapshots from the past with ancient DNA data (aDNA) from diverse periods of human prehistory. Comparing samples taken in the same region but at different time periods may indicate if there is continuity in the peopling history of that area or if a large genetic input, such as an immigration wave, has occurred. Here we propose a new modeling approach for investigating population continuity using aDNA, including two fundamental elements in human evolution that were absent from previous methods: population structure and migration. The method also considers the extensive temporal and geographic heterogeneity commonly found in aDNA datasets. We compare our spatially-explicit approach to the previous non-spatial method and show that it is more conservative and thus suitable for testing population continuity, especially when small, isolated populations, such as prehistoric ones, are considered. Moreover, our approach also allows investigating partial population continuity and we apply it to a real dataset of ancient mitochondrial DNA. We estimate that 91% of the current genetic pool in central Europe entered the area with immigrant Neolithic farmers, but a genetic contribution of local hunter-gatherers as large as 83% cannot be entirely ruled out.

Northwest China is a contacting region for East and West Eurasia and an important center for investigating the migration and admixture history of human populations. However, the comprehensive genetic structure and admixture history of the Altaic speaking populations and Hui group in Northwest China were still not fully characterized due to insufficient sampling and the lack of genome-wide data. Thus, We genotyped genome-wide SNPs for 140 individuals from five Chinese Mongolic, Turkic speaking groups including Dongxiang, Bonan, Yugur, and Salar, as well as the Hui group. Analysis based on allele-sharing and haplotype-sharing were used to elucidate the population history of Northwest Chinese populations, including PCA, ADMIXTURE, pairwise Fst genetic distance, f-statistics, qpWave/qpAdm and ALDER, fineSTRUCTURE and GLOBETROTTER. We observed Dongxiang, Bonan, Yugur, Salar, and Hui people were admixed populations deriving ancestry from both East and West Eurasians, with the proportions of West Eurasian related contributions ranging from 9 to 15%. The genetic admixture was probably driven by male-biased migration- showing a higher frequency of West Eurasian related Y chromosomal lineages than that of mtDNA detected in Northwest China. ALDER-based admixture and haplotype-based GLOBETROTTER showed this observed West Eurasian admixture signal was introduced into East Eurasia approximately 700 ∼1,000 years ago. Generally, our findings provided supporting evidence that the flourish transcontinental communication between East and West Eurasia played a vital role in the genetic formation of northwest Chinese populations.

Political Economic

The history of political-economic thought has been built up over the centuries with a uniform focus on European and North American thinkers. Intellectuals beyond the North Atlantic have been largely understood as the passive recipients of already formed economic categories and arguments. This view has often been accepted not only by scholars and observers in Europe but also in many other places such as Russia, India, China, Japan, and the Ottoman Empire. In this regard, the articles included in this collection explicitly differentiate from this diffusionist approach (“born in Western Europe, then flowed everywhere else”).

Genetic Substructure

We assembled genome-wide data from 271 ancient Iberians, of whom 176 are from the largely unsampled period after 2000 BCE, thereby providing a high-resolution time transect of the Iberian Peninsula. We document high genetic substructure between northwestern and southeastern hunter-gatherers before the spread of farming. We reveal sporadic contacts between Iberia and North Africa by ~2500 BCE and, by ~2000 BCE, the replacement of 40% of Iberia’s ancestry and nearly 100% of its Y-chromosomes by people with Steppe ancestry. We show that, in the Iron Age, Steppe ancestry had spread not only into Indo-European–speaking regions but also into non-Indo-European–speaking ones, and we reveal that present-day Basques are best described as a typical Iron Age population without the admixture events that later affected the rest of Iberia. Additionally, we document how, beginning at least in the Roman period, the ancestry of the peninsula was transformed by gene flow from North Africa and the eastern Mediterranean.

The hypothesis that the Basque language is genetically related to languages in the Caucasus region was developed in the 20th century by respected scholars including C. C. Uhlenbeck, Georges Dumézil, and René Lafon, but has recently fallen into disfavour. The author defends the Euskaro-Caucasian hypothesis in a refined model in which Basque (Euskara) is most closely related to the North Caucasian language family (but not “South Caucasian” = Kartvelian). It is maintained that this hypothesis is not only linguistically convincing, supported by hundreds of basic etymologies, sound correspondences, and shared morphology, but is also consistent with recent results in archaeology and human genetics. Among the Euskaro-Caucasian etymologies is a significant number involving small and large cattle, swine, dairying, grain and pulse crops, and tools and methods of processing crops. These lexical fields are consistent with the spread of agriculture and animal husbandry to Western Europe by means of colonisation by bearers of the Cardial (Impressed Ware) Culture who came from the Anatolian (or possibly Balkan) region, and spoke a language related to Proto-North Caucasian. The well-known genetic distinctiveness of the Basques is a result of centuries of low population size, genetic drift and endogamy, rather than purely Paleolithic ancestry. The present-day Basque people represent a genetic amalgam of the Cardial colonists with indigenous hunter-gatherers, but their Euskaro-Caucasian language is colonial, not indigenous, in origin. Basque is the sole remaining descendant of the Euskaro-Caucasian family in Western Europe, but there is evidence (in the form of substratum words) that this colonial language was formerly more widely spread in other nearby regions (Sardinia, parts of Iberia, France, the Alps, Italy, the Balkans, and perhaps beyond).

First Time

In the north-west of Wilts is a district which contains some remarkable reminiscences of the two dominant races who have influenced the history of this country. In tracing out the history of this district, as it has come down to us by the traditions and records of early chronicle writers, we arrive at an important epoch when for the first time is brought into strongly marked prominence the outline of the community which had settled there. This community, known to us later under the local name of Malmesbury, is one of the most perfect types of the primitive village which has survived in England, and to the elucidation of its chief characteristics it is proposed to devote some little attention. Keeping before us the outline made known from early records we shall see how this is gradually filled in from facts, which though gleaned from later and modern records, are nevertheless stamped as belonging to the earliest stages of history. And when this local mosaic is completely pieced in we shall be able, I think, to satisfy ourselves that what has so persistently clung to locality in later days originally belonged to a social group, types of which are still to be found in Eastern Europe and India, where society is in a state of arrested progress and has not advanced along the lines which mark its development in Western Europe.

Isotope Analyses

Genetic diversity in modern Arctic communities provides a baseline from which to assess population history. This is augmented by documenting patterns of genetic variation in prehistoric populations using ancient DNA methods, and inferring dietary resource information and adaptive strategies derived from stable isotope analyses. This chapter uses this multidisciplinary approach to examine population history and colonization events in the Aleutians of South Alaska, and the origin and population history of Paleoeskimo and Neoeskimo populations of the North American Arctic. The power to identify past demographic events relies on knowledge of both genetic and isotopic signatures of demographic events, and on acquisition of securely dated and well provenienced samples for analysis.

Genetic information contains a record of the history of our species, and technological advances have transformed our ability to access this record. Many studies have used genome-wide data from populations today to learn about the peopling of the globe and subsequent adaptation to local conditions. Implicit in this research is the assumption that the geographic locations of people today are informative about the geographic locations of their ancestors in the distant past. However, it is now clear that long-range migration, admixture and population replacement have been the rule rather than the exception in human history. In light of this, we argue that it is time to critically re-evaluate current views of the peopling of the globe and the importance of natural selection in determining the geographic distribution of phenotypes. We specifically highlight the transformative potential of ancient DNA. By accessing the genetic make-up of populations living at archaeologically-known times and places, ancient DNA makes it possible to directly track migrations and responses to natural selection.

AbstractTransition from the Stone to the Bronze Age in Central and Western Europe was a period of major population movements originating from the Ponto-Caspian Steppe. Here, we report new genome-wide sequence data from 28 individuals from the territory north of this source area – from the under-studied Western part of present-day Russia, including Stone Age hunter-gatherers (10,800–4,250 cal BC) and Bronze Age farmers from the Corded Ware complex called Fatyanovo Culture (2,900–2,050 cal BC). We show that Eastern hunter-gatherer ancestry was present in Northwestern Russia already from around 10,000 BC. Furthermore, we see a clear change in ancestry with the arrival of farming – the Fatyanovo Culture individuals were genetically similar to other Corded Ware cultures, carrying a mixture of Steppe and European early farmer ancestry and thus likely originating from a fast migration towards the northeast from somewhere in the vicinity of modern-day Ukraine, which is the closest area where these ancestries coexisted from around 3,000 BC.
