AbstractDramatic events in human prehistory, such as the spread of agriculture to Europe from Anatolia and the Late Neolithic/Bronze Age (LNBA) migration from the Pontic-Caspian steppe, can be investigated using patterns of genetic variation among the people that lived in those times. In particular, studies of differing female and male demographic histories on the basis of ancient genomes can provide information about complexities of social structures and cultural interactions in prehistoric populations. We use a mechanistic admixture model to compare the sex-specifically-inherited X chromosome to the autosomes in 20 early Neolithic and 16 LNBA human remains. Contrary to previous hypotheses suggested by the patrilocality of many agricultural populations, we find no evidence of sex-biased admixture during the migration that spread farming across Europe during the early Neolithic. For later migrations from the Pontic steppe during the LNBA, however, we estimate a dramatic male bias, with ~5-14 migrating males for every migrating female. We find evidence of ongoing, primarily male, migration from the steppe to central Europe over a period of multiple generations, with a level of sex bias that excludes a pulse migration during a single generation. The contrasting patterns of sex-specific migration during these two migrations suggest a view of differing cultural histories in which the Neolithic transition was driven by mass migration of both males and females in roughly equal numbers, perhaps whole families, whereas the later Bronze Age migration and cultural shift were instead driven by male migration, potentially connected to new technology and conquest.

Dramatic events in human prehistory, such as the spread of agriculture to Europe from Anatolia and the late Neolithic/Bronze Age migration from the Pontic-Caspian Steppe, can be investigated using patterns of genetic variation among the people who lived in those times. In particular, studies of differing female and male demographic histories on the basis of ancient genomes can provide information about complexities of social structures and cultural interactions in prehistoric populations. We use a mechanistic admixture model to compare the sex-specifically–inherited X chromosome with the autosomes in 20 early Neolithic and 16 late Neolithic/Bronze Age human remains. Contrary to previous hypotheses suggested by the patrilocality of many agricultural populations, we find no evidence of sex-biased admixture during the migration that spread farming across Europe during the early Neolithic. For later migrations from the Pontic Steppe during the late Neolithic/Bronze Age, however, we estimate a dramatic male bias, with approximately five to 14 migrating males for every migrating female. We find evidence of ongoing, primarily male, migration from the steppe to central Europe over a period of multiple generations, with a level of sex bias that excludes a pulse migration during a single generation. The contrasting patterns of sex-specific migration during these two migrations suggest a view of differing cultural histories in which the Neolithic transition was driven by mass migration of both males and females in roughly equal numbers, perhaps whole families, whereas the later Bronze Age migration and cultural shift were instead driven by male migration, potentially connected to new technology and conquest.

Prehistoric remains were recorded by CFA Archaeology Ltd (CFA) in 2002-03 during a programme of fieldwork at the landfill site within the boundaries of Stoneyhill Farm, which lies 7km to the southwest of Peterhead in Aberdeenshire. These included a clearance cairn with a Late Bronze Age lithic assemblage and a burial cairn, with Late Neolithic and Early Bronze Age lithics and Beaker ceramics. Other lithic scatters of similar date had no certain associations, although pits containing near-contemporary Impressed Wares were nearby. Additional lithic assemblages included material dated to the Mesolithic and Early Neolithic. What may be proto-Unstan Wares in an isolated pit were associated with radiocarbon dates (barley) of the first half of the fourth millennium bc. These findings represent a substantial addition to the local area's archaeological record and form an important contribution to the understanding of lithic technology and ceramics in earlier prehistoric Scotland.This paper is dedicated to the memory of Ian Shepherd, whose site visits enlightened this and other projects undertaken by one of the authors (IS).

Archaeological investigations were carried out between September and October 2014 in association with the construction of a substation for the Kintyre Peninsula to Hunterston subsea electricity cable on the Firth of Clyde. Excavations revealed a probable Early Neolithic structure, a Late Neolithic pit with atypical Grooved Ware, Bronze Age settlement and an intriguing Irish-style Early Medieval cereal-drying kiln. These discoveries are within the immediate landscape context of the extensive excavations undertaken from 2013–14 at Hunterston for the Western Link Project.

AbstractSupervised clustering or projection analysis is a staple technique in population genetic analysis. The utility of this technique depends critically on the reference panel. The most commonly used reference panel in the analysis of ancient DNA to date is based on the Human Origins array. We previously described a larger reference panel that captures more ancestries on the global level. Here, we reanalyzed DNA data from 279 ancient Eurasians using our reference panel. We found substantially more ancestral heterogeneity than has been reported. Our reanalysis provides evidence against a resurgence of Western hunter-gatherer ancestry in the Middle to Late Neolithic and evidence for a common ancestor of farmers characterized by Western Asian ancestry, a transition of the spread of agriculture from demic to cultural diffusion, at least two migrations between the Pontic-Caspian steppes and Bronze Age Europe, and a sub-Saharan African component in Natufians that localizes to present-day southern Ethiopia.

AbstractFarming-based economies appear relatively late in Northeast Europe and the extent to which they involve genetic ancestry change is still poorly understood. Here we present the analyses of low coverage whole genome sequence data from five hunter-gatherers and five farmers of Estonia dated to 4,500 to 6,300 years before present. We find evidence of significant differences between the two groups in the composition of autosomal as well as mtDNA, X and Y chromosome ancestries. We find that Estonian hunter-gatherers of Comb Ceramic Culture are closest to Eastern hunter-gatherers. The Estonian first farmers of Corded Ware Culture show high similarity in their autosomes with Steppe Belt Late Neolithic/Bronze Age individuals, Caucasus hunter-gatherers and Iranian farmers while their X chromosomes are most closely related with the European Early Farmers of Anatolian descent. These findings suggest that the shift to intensive cultivation and animal husbandry in Estonia was triggered by the arrival of new people with predominantly Steppe ancestry, but whose ancestors had undergone sex-specific admixture with early farmers with Anatolian ancestry.

The production of flint projectile points in the late stage of the Neman culture shows certain elements which are clearly similar in terms of technology and typology to the solutions known from flint-working of the people representing the Neolithic and Early Bronze Age cultures. The occurrence of such features has already been presented in relation to Neman culture ceramic production which lies at the heart of the concept of separating horizons within Linin type complexes. An in-depth analysis of the techno-typological features of flintworking in the Neman culture, and especially the typological category of projectile points, reveals similar patterns as well as cultural and chronological references in the case of ceramics. The most striking elements show analogies to those known from the south-eastern area of the cultural groupings influenced by impulses flowing from the civilization centres of the time. Traces of these influences are clear in certain typological and technological solutions, such as the forms of triangular projectile points, or in applying a trough-like retouch on such points. At the current stage of research, it is hard to determine whether the analogies observed result from not yet recognised intercultural contacts, or rather constitute a certain signum temporis characteristic of production in a wider area but during a single, specific chronological interval.

During excavation of the Vinca-Belo Brdo site a significant number of decorated items made from clay, stone, bone, and seashells or snail shells have been collected over the years. Amongst the decorated objects which could be classified as jewellery the majority are bracelets, pendants, and beads made from Spondylus and Glycymeris shells, as well as beads made from Dentalium shells. The appearance of these beads and the question of their origin have not yet been specifically considered within studies of prehistoric cultures in the central Balkans. Furthermore, they have rarely been illustrated and mentioned in archaeological site inventories, which we presume has not been because of their poor representation, but rather because of their being unfamiliar. The aim of this work is therefore to: a) systematize data about Dentalium beads from all phases of excavation of the Belo Brdo site in Vinca; b) to show the importance of this kind of jewellery in the study of resources around the Vinca settlement; and c) to indicate the wider chronological perspective and the significance of studying Dentalium beads within the prehistory of the central Balkans. Dentalium is a carnivorous Scaphopoda sea mollusc, uncommon and insufficiently studied. Representatives of this class of Scaphopoda have been found on Serbian territory in the Badenian sediments, deposited fifteen million years ago. Badenian sediments were discovered around Loznica, Belgrade, Arandjelovac, Golubac, Zajecar, and Negotin. The region of Belgrade and the surrounding area had been covered by a warm, shallow sea of normal salination. On the territory of Belgrade, offsprings of the Badenian sediments, rich in fossils, have been discovered in the city centre (Tasmajdan, Kalemegdan), as well as in many surrounding places (Rakovica, Kaludjerica, Lestani, and Jajinci) (fig. 2). Scaphopod shells found at the Vinca-Belo Brdo archaeological site are usually transversally broken. Judging by the basic appearance of the shells and their ornamentation (longitudinal stripes and rising lines) on better preserved examples (fig. 3: 1, 2, 3, 4, 5) the Fissidentalium badense type is distinct. The ornamentation of the shell is in most cases well preserved, save that in a few examples the longitudinal stripes are broken (fig. 3:22) or the outer surface of the shell has been abraded/dissolved by a physical-chemical agent. Dentalium shells have been used for making jewellery from prehistoric times right up to the present day. The reason for this lies in the regular shape of the shell, which is completely unchanged, or, with a little effort, can be used as one longer or (by breaking it laterally) a larger number of shorter cylindrical beads. On the territory of Serbia today, pre-Neolithic beads have not been known to date. Neither have they been cited in published materials from early-Neolithic to mid-Neolithic Starcevo sites. On the basis of literature, we would say that they appear for the first time in late Neolithic/early Eneolithic times, that is, in the period of the Vinca culture. After that time, it seems that Dentalium beads were mostly used during the Bronze Age, judging from the grave inventories of the necropolis in Mokrin (Moris culture), where there are findings in around 10% of graves. These are formed from fossilized shells. The beads are usually strung together and were worn around the neck. Usually they were strung in combination with beads and pendants made from other materials (for example teeth, bones, kaolin, stone, bronze etc). Since excavation of the Vinca-Belo Brdo site began in 1908, until 2009, 362 Dentalium beads were found. With the exception of one case, beads were formed from fossilized shells. Most fossilized shells were used by the inhabitants of Belo Brdo in the form in which they were found. Very rarely, traces of workmanship on the edges of beads can be noticed under magnification - carving and polishing (fig. 3: 21), showing that beads were sometimes finished off, probably when natural breaks were not rounded off but were too sharp, or when they the shells were broken to obtain smaller pieces. Beads are located in all levels of Vinca culture settlements, with depths of between ?0.7-?9.0 m (fig. 4a). However, at depths of between ?6.5 and ?7.3 m, only one bead has been found (at ?7.0 m) which indicates a reduced interest in Dentalium beads, to the extent of the cessation of their use in the corresponding period. It is not clear whether the beads were worn individually or in a string. Most beads were found individually, but this does not necessarily mean that they were not worn in strings, since these may have been dismantled prior to their deposit. Twenty-nine beads found together indicates that at least some were worn strung (?8.2 m), as do two pairs of connected beads (with the narrow end of one placed in the wider end of the second bead (fig. 3: 24). Regarding the question of how inhabitants of the Belo Brdo settlement found Dentalium shells, there is no doubt that they were collected in deposits of fossils situated in the wider surroundings of Vinca. The same kind of scaphopod Fissidentalium badense is present among shells used as beads, as well as in Miocene deposits in the area. The taphonomic characteristics of archaeological examples do not differ from samples collected in fossil deposits. It is interesting that inhabitants of the Belo Brdo collected other fossils too, sometimes bringing them to the settlement, but rarely using them for jewellery. Undoubtedly Dentalium shells were accepted as ?ready made? beads, but it is also possible that the Dentalia were chosen because they were ?in fashion?, since the Belo Brdo inhabitants may have known that they were used in other parts of the pre-historic world.

The third millennium BCE was a period of major cultural and demographic changes in Europe that signaled the beginning of the Bronze Age. People from the Pontic steppe expanded westward, leading to the formation of the Corded Ware complex and transforming the genetic landscape of Europe. At the time, the Globular Amphora culture (3300–2700 BCE) existed over large parts of Central and Eastern Europe, but little is known about their interaction with neighboring Corded Ware groups and steppe societies. Here we present a detailed study of a Late Neolithic mass grave from southern Poland belonging to the Globular Amphora culture and containing the remains of 15 men, women, and children, all killed by blows to the head. We sequenced their genomes to between 1.1- and 3.9-fold coverage and performed kinship analyses that demonstrate that the individuals belonged to a large extended family. The bodies had been carefully laid out according to kin relationships by someone who evidently knew the deceased. From a population genetic viewpoint, the people from Koszyce are clearly distinct from neighboring Corded Ware groups because of their lack of steppe-related ancestry. Although the reason for the massacre is unknown, it is possible that it was connected with the expansion of Corded Ware groups, which may have resulted in competition for resources and violent conflict. Together with the archaeological evidence, these analyses provide an unprecedented level of insight into the kinship structure and social behavior of a Late Neolithic community.

The nature of social organization during the Orcadian Neolithic has been the subject of discussion for several decades with much of the debate focused on answering an insightful question posed by Colin Renfrew in 1979. He asked, how was society organised to construct the larger, innovative monuments of the Orcadian Late Neolithic that were centralised in the western Mainland? There are many possible answers to the question but little evidence pointing to a probable solution, so the discussion has continued for many years. This paper takes a new approach by asking a different question: what can be learned about Orcadian Neolithic social organization from the quantitative and qualitative evidence accumulating from excavated domestic structures and settlements?In an attempt to answer this question, quantitative and qualitative data about domestic structures and about settlements was collected from published reports on 15 Orcadian Neolithic excavated sites. The published data is less extensive than hoped but is sufficient to support a provisional answer: a social hierarchy probably did not develop in the Early Neolithic but almost certainly did in the Late Neolithic, for which the data is more comprehensive.While this is only one approach of several possible ways to consider the question, it is by exploring different methods of analysis and comparing them that an understanding of the Orcadian Neolithic can move forward.
