The discovery of a specific form of Late Neolithic object in northeast Poland, commonly interpreted as reed arrowshaft straighteners, prompted investigation into the possible use of reed for archery in the European past. To examine the archery qualities of this raw material, and thus the likely rationale behind the manufacture and use of reed arrowshafts, a number of mechanical and experimental analyses were conducted. The results presented here indicate that reed was well suited for prehistoric archery. This is demonstrated above all by the arrowshaft stiffness required by this discipline, defined as the spine‐force, but also both the technological ease of production of arrows and their ballistic capabilities.

Gout has been part of human history for thousands of years. Skeletal evidence of the disease among past people in Europe is often associated with high-status individuals whose lifestyles comprised risk factors for gout, including increased sedentism and greater access to rich, high-caloric, food. A growing body of evidence, however, has shown that multiple factors other than lifestyle also contribute to gout development. In 2011, Buckley presented a review of modern and pre-modern gout cases in which she proposed that selective pressures may partly underlie the high prevalence of gout in the population history of the Pacific region. In this paper, we provide an update on Buckley's 2011 review of gout in human history. We also review early life stress as a potential underlying factor to consider for gout development, particularly among small prehistoric communities where opulent lifestyles traditionally associated with gout were unlikely to have occurred.

On the basis of different methods, researchers have reached different and sometimes contradicting conclusions on the question, when regular woodland management started in Europe. While some reconstruct systematic woodland management already in the Neolithic, others found it altogether improbable that woodland management should have been invented in prehistoric times. This study critically reviews the applied methods and their respective data. The aim is not only to learn about their respective strengths and weaknesses and certainly not to decide on the winner. Rather, we try to reflect on basic assumptions and whether these are the reason for seeming contradictions. [ABSTRACT FROM AUTHOR]

The recent increase in openly available ancient human DNA samples allows for large-scale meta-analysis applications. Trans-generational past human mobility is one of the key aspects that ancient genomics can contribute to since changes in genetic ancestry—unlike cultural changes seen in the archaeological record—necessarily reflect movements of people. Here, we present an algorithm for spatiotemporal mapping of genetic profiles, which allow for direct estimates of past human mobility from large ancient genomic datasets. The key idea of the method is to derive a spatial probability surface of genetic similarity for each individual in its respective past. This is achieved by first creating an interpolated ancestry field through space and time based on multivariate statistics and Gaussian process regression and then using this field to map the ancient individuals into space according to their genetic profile. We apply this algorithm to a dataset of 3138 aDNA samples with genome-wide data from Western Eurasia in the last 10,000 y. Finally, we condense this sample-wise record with a simple summary statistic into a diachronic measure of mobility for subregions in Western, Central, and Southern Europe. For regions and periods with sufficient data coverage, our similarity surfaces and mobility estimates show general concordance with previous results and provide a meta-perspective of genetic changes and human mobility.

The impact of inter-group conflict on population dynamics has long been debated, especially for prehistoric and non-state societies. In this work, we consider that beyond direct battle casualties, conflicts can also create a 'landscape of fear' in which many non-combatants near theatres of conflict abandon their homes and migrate away. This process causes population decline in the abandoned regions and increased stress on local resources in better-protected areas that are targeted by refugees. By applying analytical and computational modelling, we demonstrate that these indirect effects of conflict are sufficient to produce substantial, long-term population boom-and-bust patterns in non-state societies, such as the case of Mid-Holocene Europe. We also demonstrate that greater availability of defensible locations act to protect and maintain the supply of combatants, increasing the permanence of the landscape of fear and the likelihood of endemic warfare.

In 1935, the Russian linguist Prince Nicolai S. Trubetskoi and the French mythologist Georges Dumézil engaged in a vicious debate over a seemingly obscure subject: the structure of Northwest Caucasian languages. Based on unknown archival material in French, German, and Russian, this essay uses the debate as a pathway into the 1930s scientific and political stakes of IndoEuropeanism – the belief that European cultures emerged through the spread of a single IndoEuropean people out of a single “motherland.” Each of the two authors held strong commitments to visions of European order and its origins – in “Eurasia” for Trubetskoi and a Northern European Heimat for Dumézil. The North Caucasus, long a privileged site for Russian and European scholars, now became key to the renegotiation of the origins and reach of imagined prehistoric IndoEuropean conquerors, but also the 1930s’ debate over the value of different disciplines (linguistics, mythology, archaeology, folklore studies) for the origins of language, myth, and the European deep past. As a moment in the history of modern speculations about prehistory, pursued in the shadow of Nazi scholarship, the debate transformed fields of research – notably linguistics, comparative mythology, and structuralism – and the assumptions about the shape of Europe.

Abstract: Objectives: San Juan ante Portam Latinam is one of a small number of European Neolithic sites meeting many of the archaeological criteria expected for a mass grave, and furthermore presents evidence for violent conflict. This study aims to differentiate between what is potentially a single episode of deposition, versus deposition over some centuries, or, alternatively, that resulting from a combination of catastrophic and attritional mortality. The criteria developed are intended to have wider applicability to other such proposed events. Material and Methods: Ten new AMS 14C determinations on human bone from the site, together with previously available dates, are analyzed through Bayesian modeling to refine the site's chronology. This is used together with the population's demographic profile as the basis for agent‐based demographic modeling. Results: The new radiocarbon results, while improving the site's chronology, fail to resolve the question whether the burial represents a single event, or deposition over decades or centuries—primarily because the dates fall within the late fourth millennium BC plateau in the calibration curve. The demographic modeling indicates that the population's age and sex distribution fits neither a single catastrophic event nor a fully attritional mortality profile, but instead may partake of elements of both. Discussion: It is proposed that San Juan ante Portam Latinam was used as burial place for the mainly adolescent and adult male dead of a particular or multiple violent engagements (e.g., battles), while previously or subsequently seeing use for attritional burial by other members of one or more surrounding communities dead over the course of a few generations. The overall bias towards males, particularly to the extent that many may represent conflict mortality, has implications for the structure of the surviving community, the members of which may have experienced increased vulnerability in the face of neighboring aggressors.

Rescue excavations of the AS 4 Poljana Križevačka 1 site on the route of the A12 motorway, section Gradec-Kloštar Vojakovački covered 36152 m2 and yielded the remains of settlements from prehistory, antiquity and the Middle Ages, including an exceptional amount of data about settlement infrastructure as well as abundant material remains. The site lies on a gentle oval elevation in the valley of the Glogovnica brook, on the south-western fringes of the Poljana Križevačka village. The excavated finds show that the salvage excavations uncovered the remains of settlements from several periods of prehistory - Copper Age (Lasinja culture), Early Bronze Age (Vinkovci culture) and Late Bronze Age (younger phase of the Urnfield culture). The Late Iron Age settlement of the La Tène culture probably continued to exist in the Early Roman period. The most intensive habitation was documented in the Late Middle Ages. The intensity of habitation throughout these periods bears testimony to the exceptionally favourable position, surrounded by fertile land and situated on an important communication route connecting the upper Posavina region with the Križevci-Koprivnici area and the upper Podravina region.

There is a period of some 5000 years or so in the prehistory of Europe when horse populations were greatly depleted and perhaps even disappeared in many places. Before this time, during the Upper Palaeolithic, wild horses were common; after, during the Bronze Age, domestic horses were being raised and used across Europe. What happened in between is uncertain, in part because of the sketchy archaeological record. Debates continue as to the origins (the when, where and how) of Europe's domestic horses, including whether horse husbandry dispersed only from habitats favourable to horses on the Eurasian steppes or whether there was local domestication in temperate Europe. This paper reviews the evidence for the transition from wild horses to domestic horses in Europe. [ABSTRACT FROM PUBLISHER]

The melting of the Scandinavian Ice-Sheet in the early Holocene allowed humans to populate the northernmost parts of Europe. Recent excavations of archaeological sites on the riverbank, floodplain and kame terraces of the River Rena, southeast Norway have defined periods of human occupation in riverside environments, which became ice-free during the last deglaciation. In this paper, we extend the scope of previous archaeological work by examining the sedimentology and chronology of five riverside sedimentary sequences along the River Rena. Our aims were to reconstruct the Holocene evolution of part of the river, and determine whether changes in Holocene settlement patterns might be linked to changes in river evolution and/or climate. Results show: (1) widespread draining of the kame terraces of the River Rena occurred shortly before the first consistent human settlement in the area began c. 8 ka BP; (2) human settlement was maintained until the present day, except during a period of previously undocumented abandonment between c. 4 and 3 ka BP, associated with a sustained period of high river discharge. We link the establishment of first undisputable settlement to reduced water levels as glaciers retreated upstream during a 'warmer' phase of the early Holocene, shortly after the 8.2 ka climatic downturn event. The most recent abandonment of the riverbank settlements 4-3 ka BP occurred during the last phase of glacier advance in the River Rena region, which has been linked to the Europe-wide late- Holocene Thermal Decline (Neoglacial) downturn in climate.

La vallée de la Somme a joué, au milieu du XIXe siècle, un rôle majeur dans la reconnaissance de la préhistoire en tant que discipline scientifique. Elle demeure toujours au cœur des problématiques et des recherches sur les premiers peuplements humains en Europe du Nord-Ouest. Le colloque pluridisciplinaire « Toute une (pré)histoire en Somme », qui s'est tenu les 22–24 novembre 2018 à Abbeville, se fixait pour objectif premier d'établir un état des connaissances et des questions actuelles dans les domaines des études préhistoriques et de l'histoire de la préhistoire. During the middle of the 19th century, the Somme valley played a major role in the recognition of prehistory as a scientific discipline. It is still at the heart of issues and research on the first human settlements in northwestern Europe. The multidisciplinary colloquium "Toute une (pré)histoire en Somme", which was held on 22–24 November 2018 in Abbeville, set itself the primary objective of establishing a state of knowledge and current issues in the fields of prehistoric studies and the history of prehistory.

Anthropogenic pollen indicators in pollen records are an established tool for reconstructing the history of human impacts on vegetation and landscapes. They are also used to disentangle the influence of human activities and climatic variability on ecosystems. The comprehensive anthropogenic pollen-indicator approach developed by Behre (1981) has been widely used, including beyond its original geographical scope of Central and Western Europe. Uncritical adoption of this approach for other areas is risky because adventives (plants introduced with agriculture) in Central Europe can be apophytes (native plants favoured by human disturbances) in other regions. This problem can be addressed by identifying region-specific, anthropogenic-indicator pollen types and/or developing region-specific, human-impact indices from pollen assemblages. However, understanding of regional variation in the timing and intensity of human impacts is limited by the lack of standardization, validation and intercomparison of such regional approaches. Here we review the most common European anthropogenic pollen-indicator approaches to assess their performance at six sites spanning a continental gradient over the boreal, temperate and Mediterranean biomes. Specifically, we evaluate the human-indicator approaches by using independent archaeological evidence and models. We present new insights into how these methodologies can assist in the interpretation of pollen records as well as into how a careful selection of pollen types and/or indices according to the specific geographical scope of each study is key to obtain meaningful reconstructions of anthropogenic activity through time. The evaluated approaches generally perform better in the regions for which they were developed. However, we find marked differences in their capacity to identify human impact, while some approaches do not perform well even in the regions for which they were developed, others might be used, with due caution, outside their original areas or biomes. We conclude that alongside the increasing wealth of pollen datasets a need to develop novel tools may assist numeric human impact reconstructions. • Indicator species is the main method in palaeoecology for inferring human impact. • If a pollen indicator is apophytic or adventive is vital for the results analysis. • Care must be taken when adopting an index approach outside its calibration area. • A good taxonomic resolution of a pollen type allows assessing its indicative level.

Forty-seven potato virus A (PVA) isolates from Europe, Australia, and South America's Andean region were subjected to high-throughput sequencing, and 46 complete genomes from Europe ( n = 9), Australia ( n = 2), and the Andes ( n = 35) obtained. These and 17 other genomes gave alignments of 63 open reading frames 9,180 nucleotides long; 9 were recombinants. The nonrecombinants formed three tightly clustered, almost equidistant phylogroups; A comprised 14 Peruvian potato isolates; W comprised 37 from potato in Peru, Argentina, and elsewhere in the world; and T contained three from tamarillo in New Zealand. When five isolates were inoculated to a potato cultivar differential, three strain groups (= pathotypes) unrelated to phylogenetic groupings were recognized. No temporal signal was detected among the dated nonrecombinant sequences, but PVA and potato virus Y (PVY) are from related lineages and ecologically similar; therefore, "relative dating" was obtained using a single maximum-likelihood phylogeny of PVA and PVY sequences and PVY's well-supported 157 CE "time to most common recent ancestor". The PVA datings obtained were supported by several independent historical coincidences. The PVA and PVY populations apparently arose in the Andes approximately 18 centuries ago, and were taken to Europe during the Columbian Exchange, radiating there after the mid-19th century potato late blight pandemic. PVA's phylogroup A population diverged more recently in the Andean region, probably after new cultivars were bred locally using newly introduced Solanum tuberosum subsp. tuberosum as a parent. Such cultivars became widely grown, and apparently generated the A × W phylogroup recombinants. Phylogroup A, and its interphylogroup recombinants, might pose a biosecurity risk.[Formula: see text] Copyright © 2021 The Author(s).

The extensive use of mollusc shell as a versatile raw material is testament to its importance in prehistoric times. The consistent choice of certain species for different purposes, including the making of ornaments, is a direct representation of how humans viewed and exploited their environment. The necessary taxonomic information, however, is often impossible to obtain from objects that are small, heavily worked or degraded. Here we propose a novel biogeochemical approach to track the biological origin of prehistoric mollusc shell. We conducted an in-depth study of archaeological ornaments using microstructural, geochemical and biomolecular analyses, including 'palaeoshellomics', the first application of palaeoproteomics to mollusc shells (and indeed to any invertebrate calcified tissue). We reveal the consistent use of locally-sourced freshwater mother-of-pearl for the standardized manufacture of 'double-buttons'. This craft is found throughout Europe between 4200-3800 BCE, highlighting the ornament-makers' profound knowledge of the biogeosphere and the existence of cross-cultural traditions., Competing Interests: JS, SA, PB, MB, TC, AC, FD, AG, MH, HK, GM, CM, KP, LP, HS, ST, CT, JT, JW, FM, BD No competing interests declared, (© 2019, Sakalauskaite et al.)

The history of southern Africa involved interactions between indigenous hunter-gatherers and a range of populations that moved into the region. Here we use genome-wide genetic data to show that there are at least two admixture events in the history of Khoisan populations (southern African hunter-gatherers and pastoralists who speak non-Bantu languages with click consonants). One involved populations related to Niger-Congo-speaking African populations, and the other introduced ancestry most closely related to west Eurasian (European or Middle Eastern) populations. We date this latter admixture event to ∼900-1,800 y ago and show that it had the largest demographic impact in Khoisan populations that speak Khoe-Kwadi languages. A similar signal of west Eurasian ancestry is present throughout eastern Africa. In particular, we also find evidence for two admixture events in the history of Kenyan, Tanzanian, and Ethiopian populations, the earlier of which involved populations related to west Eurasians and which we date to ∼2,700-3,300 y ago. We reconstruct the allele frequencies of the putative west Eurasian population in eastern Africa and show that this population is a good proxy for the west Eurasian ancestry in southern Africa. The most parsimonious explanation for these findings is that west Eurasian ancestry entered southern Africa indirectly through eastern Africa.
