The active compounds found in many plants have been widely used in traditional medicine and ritual activities. However, archaeological evidence for the use of such plants, especially in the Palaeolithic period, is limited due to the poor preservation and fragility of seed, fruit, and other botanical macro-remains. In this study, we investigate the presence and possible uses of Ephedra during the Late Pleistocene based on the analysis of exceptionally preserved plant macrofossils recovered from c. 15 ka year-old archaeological deposits at Grotte des Pigeons in northeastern Morocco. This cave has yielded the earliest carbonized plant macrofossils of Ephedra, which were found concentrated in a human burial deposit along with other special finds. Ephedra is a plant known to produce high amounts of alkaloids, primarily ephedrine and pseudoephedrine, which have been utilized in traditional medicine. Direct radiocarbon dates on both Ephedra and the human remains indicate that they were contemporaneous. To understand the uses of Ephedra by people at the site, we discuss the different pathways through which plant remains could have arrived. We suggest that the charred cone bracts of Ephedra likely represent residues of the processing and consumption of the plant's fleshy cones, which may have been valued for both their nutritional and therapeutic properties. Furthermore, we interpret the presence of Ephedra and its deposition in the burial area as evidence that this plant played a significant role during the funerary activities. [ABSTRACT FROM AUTHOR]

Finger flutings are channels drawn in soft sediments covering walls, floors and ceilings of some limestone caves in Europe and Australia and in some cases date as far back as 50,000 years ago. Initial research focused on why they were made, but more recently, as part of a growing interest in the individual in the past, researchers began asking questions about who made them. This shift in direction has led to claims that by measuring the width of flutings made with the three middle fingers of either hand, archaeologists can infer the ordinal age, sex and individuality of the 'fluter'. These claims rest on a single dataset created in 2006. In this paper, we undertake the first critical analysis of that dataset and its concomitant methodologies. We argue that sample size, uneven distribution of sex and age within the sample, non-standardised medium, human variability, the lack of comparability between an experimental context and real cave environments and assumptions about demographic modelling effectively negate all previous claims. To sum, we find no substantial evidence for the claims that an age, sex and individual tracing can be revealed by measuring finger flutings as described by Sharpe and Van Gelder (Antiquity 80: 937-947, 2006a; Cambridge Archaeological Journal 16: 281–95, 2006b; Rock Art Research 23: 179–98, 2006c). As a case study, we discuss Koonalda Cave in southern Australia. Koonalda has the largest and most intact display of finger flutings in the world and is also part of a cultural landscape maintained and curated by Mirning people. [ABSTRACT FROM AUTHOR]

In this article, we present the results of the research carried out at the Gravettian occupation level of Cueva del Arco (Spain). For this purpose, a multidisciplinary investigation has been carried out in which all the elements recovered in the excavations carried out since 2015 at this site have been studied. The results are contextualised alongside all of the existing Gravettian sites in Mediterranean Iberia. The study of the material culture, the fauna, the landscape, and the dating has allowed us to approach the occupations of the site from many perspectives and has permitted us to conclude that Cueva del Arco was occupied sporadically at the beginning of the Gravettian period by a small human group in what would be the beginning of the consolidation of the anatomically modern humans (AMH) in this territory. Furthermore, these occupations were preceded by others belonging to the Aurignacian, which left hardly any remains in the cave. The data presented in this article lead us to believe that Cueva del Arco is a site of great importance for the knowledge of the beginning of the AMH settlement in the Iberian Mediterranean, both in its expansion towards the south and in its definitive consolidation in this territory.

Despite the presence of a theoretical model describing the settlement patterns of Palaeolithic sites in Northwestern Iberia, it has not yet been empirically tested using statistical analysis. This study explores the settlement patterns of the Palaeolithic period in Northwestern Iberia within two regions that share similar chronology and research traditions: the Northern and Central Mountain ranges of Northwestern Iberia. Employing Geographic Information Systems (GIS) and spatial statistics, the methodology has provided robust empirical support for several aspects of the theoretical model. The study rigorously tested the theoretical model proposed in the existing literature using statistical analysis and a comprehensive dataset of 50 variables. The findings highlight significant regional distinctions in the settlement patterns of Palaeolithic sites within both areas of Northwestern Iberia. This research not only confirms certain hypotheses related to Palaeolithic site locations but also underscores the need for further examination and refinement of others, particularly considering the notable regional variations.

The creation of rock art in the deep areas of caves was one of the most unique symbolic activities of Magdalenian societies in southwestern Europe between 13.5 and 21 thousand years ago. Previous research has suggested that these works of art were not placed in caves at random but rather their location corresponds to a pre-established structure. However, despite the suggestive idea of pre-planning the decoration of the endokarst, it is challenging to demonstrate the relationship between different works and between them and their immediate spatial context due to the lack of common objective criteria. In this study, we have examined the iconographic and spatial characteristics of 500 Magdalenian graphic units in nine caves in the Cantabrian and Pyrenees mountain ranges (southwestern Europe) to identify patterns of graphic construction based on their cave location. We designed a workflow that includes geomorphological analysis for a virtual reconstruction of the state of the caves during the Magdalenian, analysis of graphic units (GU) through geographic information systems (GIS) using a Python script, and multivariate statistical study of the spatial and iconographic parameters of these figures. This has allowed us to identify different groups of figures: some were specifically created to be seen, using various techniques and selecting locations with good visibility, accessibility, or capacity to accommodate people, while others sought the opposite. There is also a correlation between the techniques used and their location in caves, perhaps aiming for resource economization. These data support the existence of different uses for the deep sectors of caves during the Magdalenian period. [ABSTRACT FROM AUTHOR]

The Pleistocene sediments of Nihewan Basin in NE China are intensively studied since ca. 100 years because of its rich mammalian fossil record and abundant stone-artifact-bearing layers. To better understand the mechanisms underlying past climate and environmental changes in the basin, three sediment sections at the Dachangliang location were investigated using a multi-proxy toolbox of sedimentological, magnetic susceptibility (MS) and micropalaeontological analyses. The exposed sediments are lithologically mostly relatively homogeneous, with grain sizes in a relatively small range. However, variations in colour, bedding structures, concentrations of magnetic minerals and the ostracod assemblage were used to correlate the three sections to form the synthetic NH-T section of 86.2-m total length. The sediments mainly represent varicoloured silt of probably reworked loess deposits, partially interbedded with fine sand layers and minor contributions of clay particles. These sediments are interpreted to have accumulated in wetlands alternating with deposition on an alluvial plain, and with a lacustrine setting which probably existed from time to time. These different depositional settings are expressed in the three dominant fine to coarse silt-sized components and the ostracod-assemblage changes (mostly Limnocythere flexa, Ilyocypris spp. and Leucocythere sp.). The recorded ostracods of laterally apparently consistent white marl beds (dominantly Cytherissa lacustris) were used to stratigraphically correlate these sections. The resulting NH-T section was further correlated with the three proximal artefact-bearing sections Majuangou, Banshan and Xiantai which have published magnetostratigraphic data. The correlation shows that the investigated sedimentary sequence was probably formed between ca. 1.7 and 0.9 Ma. The relatively continuous synthetic sequence NH-T represents three main wetter periods with three intervening drier intervals, possibly synchronous with interglacial (S23-S20, S15-S13 and S10-S9) and glacial (L20- L18, L17-L16 and L13-L11) periods which were previously inferred from the palaeoclimatic records of the Chinese Loess Plateau (CLP) in the SW of the Nihewan Basin.

The Radochowska Cave is known primarily from the find of a cave bear skull, intended to be placed intentionally by Palaeolithic hunters in a 'stone cage'. This find was supposed to be proof of the existence of the cult of bear hunters at this site. Critical analysis did not give a clear answer to its occurrence or a clear negation of this phenomenon. Research is not facilitated by the fact that a large part of the collection was lost after World War II. The found part, especially numerously represented by predatory mammals, made it possible to verify the old lists of fauna and extend them with a number of new species, often unknown from the Polish Sudetes, such as Cuon alpinus europaeus or Panthera pardus. The analysis showed the presence of two main faunistic associations. The older one, dated to MIS 3, is represented by a number of cold-loving forms. Remains of Holocene species and those from the very end of the last glaciation represent the second faunal assemblage. [ABSTRACT FROM AUTHOR]

Photography played an important part in the revelation of deep time in the later nineteenth century, leading to the invention of a new epoch – the palaeolithic. This article investigates how photography participated in creating palaeoliths, eoliths, and stone collectables in the late nineteenth and early twentieth century when the boundaries between artefacts and non-artefacts, culture and nature, were at issue. I examine the emergence of visual conventions for depicting ancient stone implements in archaeological publications and museums and the development of standardized artefact photography. I investigate how the mechanical objectivity of photography was deployed in archaeological experiments demonstrating that eoliths, like photographs, could be produced using non-human agencies. I explore the utopian and left-wing cultures of collecting and photographing figure-stones and picture-stones; collecting cultures based around an alternative connoisseurship of pareidolia – the "primitive" skill of discerning animals, faces and body parts in stones. Comparing case studies of authenticated, unauthenticated, and, hoax artefacts, I examine how authentication practices preserved the personal authority of archaeological specialists, by emphasizing encounters between experts and stones, over those between experts and photographs. Photography always had the potential to destabilize the power relations of archaeological authentication, but, in practice, reinforced and extended them. [ABSTRACT FROM AUTHOR]

This paper is a response to the conference session 'Generic MSA: fact or fiction?' held as part of the PanAfrican Association Conference in 2022 in Unguja, Tanzania. It questions the validity of the concept of a 'generic Middle Stone Age' and goes beyond the simple debate of terminology that has persisted for nearly 75 years. Instead, it uses this as a starting point to discuss the past, present and future of lithic analyses, including the history of terminology in the African Stone Age, the current topics of lithic enquiry and the role of lithic analysis following the Third Science Revolution. It highlights the effect of tensions between science versus humanities approaches and provides suggestions for future lithic analysts. Lithic studies remain of great importance but are only one source of evidence in modern interdisciplinary human origins research. The paper contends that there is not a single approach suitable for all sites or regions since analyses are contingent upon the questions being asked. Instead, it emphasises opportunities for multivocality and suggests that despite the focus here on the Middle Stone Age the conclusions reached are more widely applicable to other times and places.

We propose a transmission time investment model for integrating the tenets of human behavioral ecology and cultural evolutionary theory to investigate agency and optimality in the social transmission of lithic technologies. While the cultural transmission process is often overlooked in discussions of optimality, we view it as a critical area for the application of adaptive reasoning to further understand the mechanisms responsible for change in lithic technologies. The proposed model modifies a technological intensification model based on the marginal value theorem (Bettinger et al. Journal of Archaeological Science, 33(4), 538–545, 2006; Mohlenhoff and Codding Evolutionary Anthropology, 26(5), 218–227, 2017) to explore how transmissibility may have affected the complexity of socially transmitted lithic production systems during the Pleistocene. This transmission investment model is contrasted with a passive demographic model derived from traditional explanations for changes in lithic technologies. To highlight how optimal considerations of transmissibility may have affected the long-term evolution of lithic technologies, we apply this model to three Pleistocene archaeological case studies investigating increases and decreases in lithic technological complexity. We propose that technological changes in each of these case studies is consistent with the predictions of the model, suggesting that time management strategies may have played a role in the long-term evolution of Pleistocene technologies. It is unlikely that transmission constraints alone were wholly responsible for the observed patterns, and future research should refine the measures of time availability and cost used here, as well as explore the interplay between transmission investment and other optimizing and social constraints.

Prehistoric wooden projectiles likely have a complex evolutionary story in a similar way to stone tools, depending on their functions, and the cognitive and physical capabilities of hominins who used them. The technologies of some ancient projectiles (e.g., spears, arrows) can be studied more directly because they were equipped with stone points which survive archaeologically, but other implements made entirely of wood are extremely rare archaeological finds and need an indirect study of their ethnological diversity to try to shed light on their evolution. The evolution of throwing sticks is often restricted to the invention of boomerangs which, as returning objects, have fascinated Europeans, particularly since the early 19th century colonisation of Australia. However, the innovation of returning boomerangs is probably relatively recent, compared to their entire technological evolution. The resulting technological diversity of forms through time is reflected in the different morphological types of ethnological throwing sticks found on the Australian continent but is also present in other parts of the world. A scheme of evolution for throwing sticks is proposed here, according to the technology that can be observed on numerous ethnological objects studied in museum collections, and experience gained from throwing replicas, which allow us to distinguish different development phases for these projectiles.

The pathogenic environment has been a constant shaping presence in human evolution. Despite its importance, this factor has been given little consideration and research. Here, we use experimental archaeology and microscopic analysis to present and support a novel hypothesis on the pathogenic properties of bifacial butchery tools during the Middle Pleistocene. Use-wear evidence from the Acheulean site of Boxgrove, Sussex suggests that a sample of flint bifaces were used for butchery tasks for a remarkably limited duration. Circumstantial evidence from other Acheulean sites, such as the apparent discard of bifaces at single-episode butchery sites, and biface caching sites, also suggest limited-use, and extend this interpretation beyond Boxgrove. There is no current utilitarian explanation for why such an apparently over-engineered tool would be discarded after such a limited duration of use. This pilot study demonstrates, via experimental investigation, that residual animal tissue from performing butchery tasks cannot be completely removed from the flake scars of flint bifaces using prehistorically available cleaning methods. It is argued that the animal tissue is likely to begin spoiling within hours of butchery, which poses a significant risk of introducing pathogens into foodstuffs if the biface is reused, resulting in foodborne illness. Subsequently, hominins likely learned to minimise this risk by discarding each flint bifacial tool after a single episode of butchery.

Here, we present the first-ever attempt to combine palaeoenvironmental records (n = 17) from dated stratigraphic sequences with Geographic Information System (GIS) spatial modelling of archaeological sites (3 phases; n = 306 sites) in the Ganga Plain. The spatial modelling assesses the distribution of archaeological sites and phases on maps showing changing elevation, geology, geomorphology, biome, and rainfall variability within the Ganga Plain, aiming to evaluate the human-environment relationship during the Late Quaternary Period. The compilation of oxygen and hydrogen isotopic composition (δ18O and δD values) and pollen-based environment reconstructions for the last ∼100 ka indicates high rainfall conditions during ∼100–75 ka, ∼10–5 ka, and ∼3.6–1.3 ka. Fluctuating rainfall conditions were observed during ∼75–25 ka and ∼18–15 ka, while the period from ∼25 to 18 ka was the weakest monsoon phase, marking the Last Glacial Maximum. Arid conditions were also observed during ∼15–10 ka and ∼5–3.6 ka. The archaeological review suggests the presence of the Acheulian culture, diverse Mesolithic cultures, and the Neolithic phase marked by advanced agriculture and pottery production in the Ganga Plain. The past environmental analyses show changes in settlement areas correlating with rainfall variations. Frequent climate changes and increasing population density during the Late Pleistocene-Early Holocene boundary probably forced prehistoric humans to adopt agricultural practices. The distribution of archaeological sites representing different cultural phases on the modern spatial maps of landscape variability (e.g., elevation, rainfall, geomorphology, and geology) reflects an intricate relationship between prehistoric human settlements, monsoonal rainfall, and climate-driven landform processes. Our assessment suggests that the integration of archaeological sites, geological mapping, vegetation analysis, and palaeoclimate records has the potential to provide valuable insights into ancient human-environment interactions. Therefore, we recommend continued interdisciplinary research in these fields to further enhance our knowledge of prehistoric societies and their responses to changing landscapes and climates in the Ganga Plain.

Archaeologists use a method of evaluating the characteristics of flakes, called scoring, to distinguish geofacts (pseudo‐artefacts or eoliths) from artefacts. Lower total scores are considered indicative of a natural source of the finds, while higher ones support the opposite. However, this method has some limitations. The most important are the small quantity of assemblages subject to such an analysis and the unclear boundary drawn by a ranking within a point‐based score evaluation between collections with finds of cultural and anthropic origin. Here, we present a method that minimizes these limitations. It consists of a statistical approach using scoring percentages, a new method of visualizing them and the application of clustering. This way, we obtained clear differences between pseudo‐artefacts and artefacts by considering flakes from six flint assemblages from Central Europe as well as an experimental assemblage.

Societal Impact Statement Cave art has been an integral part of human history, providing a glimpse into the lives and cultures of our ancestors. Prehistoric botanical art is an important medium that can help us to redefine our intimate relationship with plants. The findings from our work provide some evidence from the European Palaeolithic period that modern plant awareness disparity (PAD) might be more deeply rooted in our past. By inspiring a deeper appreciation and understanding of the natural world, cave art can help people to reconnect with plants, thus tackling PAD.

Archaeological excavations have revealed important sites from the prehistoric sites, with the cultural achievements of the early lithic tools of hunters-gatherers in the Palaeolithic, to the emergence of the farmer-village societies in the Neolithic, reaching on to urbanisation and the complex societies of the Chalcolithic. On the other hand, natural landscapes reveal the distribution of prehistoric sites near resources related to open-air lands or in caves. The biggest asset of presenting prehistoric sites is in not only boosting tourism and local economy, but also diversifying cultural activities. This covers not only the preserving and restoration work on the original sites, but also a "Discovery Centre" by creating sites like "Open-air Stand" with a permanent exhibition, as well as indoor and outdoor spaces. These can be dedicated to workshops, conferences and temporary exhibitions, and allows visitors to learn and practice "Early Human Lifestyle" activities. Attracting visitors to prehistoric sites and museums complements the sites with new job opportunities via restaurants, gift shops and bookstores, in order to achieve prosperity and welfare within the partnerships. This paper comes into three directions and depends on the UN’s Sustainable Development Goals "SDGs"; first, analysing the problem and challenges, second a more dynamic design of prehistoric sites, while the third is for the strategy's feasibility, refreshing and possible benchmarks.

In the Upper Palaeolithic levels of the site of Grotta Continenza (Abruzzo, Italy), numerous shells shaped as half-moons have been found. These artifacts, being important examples of ancient ornaments, have been regularly subjects of study, but the production process has only been hypothesised. This research, with the support of an experimental protocol, presents a possible manufacturing sequence for their creation.

The application of Zooarchaeology by Mass Spectrometry (ZooMS) on Pleistocene sites in Europe and northern Asia has resulted in the discovery of important new hominin fossils and has expanded the range of identified fauna. However, no systematic, large-scale application of ZooMS on Palaeolithic sites in East Asia has been attempted thus far. Here, we analyse 866 morphologically non-diagnostic bones from Jinsitai Cave in northeast China and Yumidong Cave in South China, from archaeological horizons dating to 150–10 ka BP. Bones from both sites revealed a high degree of collagen preservation and potentially time-related deamidation patterns, despite being located in very distinct environmental settings. At Jinsitai, we identified 31 camel bones, five of which were radiocarbon dated to 37–20 ka BP. All dated specimens correspond to colder periods of Marine Isotope Stages 3 and 2. We regard the presence of camels at Jinsitai as evidence of wild camels being a megafauna taxon targeted, most likely by early modern humans, during their expansion across northeast Asia. This large-scale application of ZooMS in China highlights the potential of the method for furthering our knowledge of the palaeoanthropological and zooarchaeological records of East Asia.

The relationship between tool form and function is fundamental to hominin behaviour and evolution. Acheulean handaxes are known for their general consistency across more than a million years and three continents, albeit with some variation in size and shape. However, the influence of this variation on cutting has only rarely been studied, mostly in either butchery or generalized cutting tasks. Yet evidence indicates that handaxes were used for woodworking by at least 1.5 mya. Here, we experimentally tested whether woodworking could have exerted selective pressures on handaxe form. Additionally, these data were compared with a previous experiment that tested flakes during woodworking. For handaxes, no significant relationships were detected in woodworking efficiency. Accordingly, woodworking likely did not exert strong selective pressures on handaxe variability. However, the effectiveness shown by handaxes further demonstrates the functional flexibility of this technology, which is likely a factor contributing to their use over broad temporal, geographical and ecological spans. When comparing handaxes with flakes, only the smallest flakes were found to be significantly less efficient than handaxes. Therefore, the functional demands of woodworking were likely influencing hominin technological decisions about flake morphology, or the selection of flakes for woodworking, more than they were handaxe morphology.

Predictive spatial analysis in archaeology refers to the use of geostatistical and computational techniques to assess the relationships between the distribution of archaeological sites and the environmental context. It is increasingly becoming an essential tool in scientific-academic research and rescue archaeology. In the interconnection between these two working contexts, this study aims to explore the advantages of applying an inductive approach, combining Geographical Information Systems (GIS) and geostatistical methods, to identify areas with different degrees of probability for the preservation of the Palaeolithic record in the lower valley of the Lis River (Leiria region, central Portugal). Topographic, hydrographic, geological, and geomorphological data were collected, processed, and integrated into a spatial database, using a GIS, to define the environmental conditioning factors. After applying a spatial multicollinearity procedure, slope, topographical position index, cost-weighted distance to access the watercourses, heat load index and lithology were chosen as input variables for the predictive modelling. Archaeological data, corresponding to the location of known Palaeolithic sites, were also retrieved from the official records. Three models were implemented using regression and multi-criteria methods; for Model 1 a Generalised Additive Model (GAM) was applied, while for Model 2 and Model 3 two distinct combinations of Probabilistic Frequency Ratio (PFR) and Analytic Hierarchy Process (AHP) were used. The spatial cross-tabulation between the obtained predictive maps and the location of the known Palaeolithic sites shows that all the models are acceptable. However, the combinations of PFR + AHP seem to evidence greater efficacy compared to the GAM. Model 3 offers the best performance (90%), followed by Model 2 (87%) and Model 1 (68%). Possible sources of inaccuracies in the input data and the spatial modelling results were critically discussed. Model 3 generated the most robust and reliable predictive prototype map. The maps produced can serve local and regional agencies as a complement and aid decision-making in public policies for spatial planning, and in the conservation/management of cultural heritage. These cartographic representations can provide quicker identification of areas of interest, for example, in the context of rescue archaeology, along with a substantial reduction in time and costs for project promoters, as well as helping in the environmental impact assessments.

Geoconservation measures in the River Tejo, the Portuguese reach of the Tagus, are compared with those in the Thames downstream of London (UK). Both are fluvio-estuarine reaches with staircases of Pleistocene depositional terraces, each with important sedimentary, palaeontological and archaeological records. In both rivers, conservation measures are in place that aim to protect these records, promote research and inform the public. Inevitably there are differences in approach. Whereas Thames Quaternary interests are protected by a network of British statutory site designations, outreach is to the fore in the Tejo. Contrasting examples are highlighted here. The Tejo has interpretative materials in local museums and detailed explanatory displays at the low-terrace archaeo-geological site of Foz do Enxarrique, near the border with Spain, and at other sites. The Thames, in contrast, has few examples of physical outreach provision and limited formal protection for Pleistocene archaeological material outside the geological network, although extensive informal protection is provided by interaction between local geological groups and county and local-authority administrations. There is also a considerable difference in the degree of threat, with the Tejo above Lisbon being a relatively undeveloped valley, albeit with sporadic quarrying for aggregate, whereas the Lower Thames is an established area for infrastructure development, lying to the east of London, close to the river crossing of the orbital motorway. The different climate in the two regions profoundly influences the longevity of exposures in Quaternary deposits, with significant implications for management strategies. The comparison exercise reveals that each region would benefit from greater development of approaches used more prominently in the other; outreach measures in the Portuguese style would greatly enhance some of the Thames sites, but formal designation of Tejo exposures could prevent damaging operations being undertaken by owners who lack knowledge of their value, as exemplified by a case study of sites at Alpiarça, ~ 130 km upstream from Lisbon.

Aims/hypothesisThe evidence for the role of contemporary dietary patterns, trends and predominant aspects of energy intake in a typical American diet and in type 2 diabetes risk is limited. Therefore, we examined the association between dietary pattern scores created to reflect the 2015 Dietary Guidelines for Americans (DGA) Scientific Report, a Palaeolithic (Palaeo) diet, a diet high in 'empty calories', and the A Priori Diet Quality Score (APDQS) (cohort reference) and type 2 diabetes risk over time.MethodsWe carried out a prospective analysis of 4719 young adult black and white men and women from the Coronary Artery Risk Development in Young Adults (CARDIA) study with repeated dietary histories collected at study years 0, 7 and 20. Using multivariable Cox proportional hazards regression models, we examined the association between time-dependent cumulative average dietary pattern scores and incident type 2 diabetes.ResultsDuring the 30 year follow-up period, 680 (14.4%) incident cases of type 2 diabetes occurred. There was no association between the 2015 DGA, Palaeo or empty calorie scores and type 2 diabetes risk in the overall population. Participants in the fourth quartile of the APDQS, reflecting a more healthful dietary pattern, had a 45% lower risk of type 2 diabetes compared with those in the lowest quartile (HR 0.55 [95% CI 0.41, 0.74]). In stratified analyses there was an inverse association for the 2015 DGA in non-smokers per SD (HR 0.86 [95% CI 0.74, 0.99]) and an inverse association for the empty calorie score in white women (HR 0.76 [95% CI 0.60, 0.96]) as well as in a subgroup analysis of the Palaeo index of participants who maintained a high score over 20 years (per SD, HR 0.59 [95% CI 0.39, 0.88]).Conclusions/interpretationHigher levels of the APDQS, which largely aligns with the 2015 DGA, were strongly inversely associated with 30 year type 2 diabetes risk in the CARDIA cohort; the results from the other patterns were nuanced and need to be considered in the context of the study and potential biases.

From the period of the Neanderthals to those of the Late Neolithic populations, the Bükk Mountains region played an important part in the lives of various prehistoric societies, and the varied geological history of this territory provided distinct circumstances for the production of stone implements. The major goal of our research is to outline the current state of information concerning the prehistoric use of the diverse silicified source materials of the Bükk mountains. The results of these studies are presented concerning four selected local rock types, cited in the archaeological literature as the silicified sandstone of Egerbakta, the radiolarite and hornstone (black chert), the silicified marlstone and the quartz-porphyry (metarhyolite). Except for the latter, little attention has previously been paid to studying them in detail. Our new petrographic analyses revealed two variants of the raw material from Egerbakta: a silicified sandstone and a diatomaceous detrital chert. The other samples turned out to be radiolarites. This result confirmed what was already suggested for the hornstones (black cherts), however, it has new consequences for the “silicified marlstone”. Regarding the prehistoric use of the selected raw materials, archaeological data show interesting dynamics through time. The Mousterian groups of the region used a large spectrum of rocks for lithic tools with a preference for hornstone (black cherts) and radiolarite in the southern part, and the quartz-porphyry (metarhyolite) in the northeastern part. The Bábonyian/Micoquian assemblages are characterized by a bifacial toolkit and an apparent preference for quartz-porphyry (metarhyolite). At the beginning of the Upper Palaeolithic, a new attitude appears in the region: the Aurignacian groups almost completely ignored local sources. During the Neolithization of the Carpathian Basin, the lithic assemblages of the Alföld Linear Pottery culture became more and more habituated to the locally available rock types, albeit their raw material economy was based on limnosilicites and obsidian. Another change took place during the Late Neolithic when supra-regional sources became dominant over local or regional sources.

Understanding mobility and landscape use is important in reconstructing subsistence behavior, range, and group size, and it may contribute to our understanding of phenomena such as the dynamics of biological and cultural interactions between distinct populations of Upper Pleistocene humans. However, studies using traditional strontium isotope analysis are generally limited to identifying locations of childhood residence or nonlocal individuals and lack the sampling resolution to detect movement over short timescales. Here, using an optimized methodology, we present highly spatially resolved 87Sr/86Sr measurements made by laser ablation multicollector inductively coupled plasma mass spectrometry along the growth axis of the enamel of two marine isotope stage 5b, Middle Paleolithic Neanderthal teeth (Gruta da Oliveira), a Tardiglacial, Late Magdalenian human tooth (Galeria da Cisterna), and associated contemporaneous fauna from the Almonda karst system, Torres Novas, Portugal. Strontium isotope mapping of the region shows extreme variation in 87Sr/86Sr, with values ranging from 0.7080 to 0.7160 over a distance of c. 50 km, allowing short-distance (and arguably short-duration) movement to be detected. We find that the early Middle Paleolithic individuals roamed across a subsistence territory of approximately 600 km2, while the Late Magdalenian individual parsimoniously fits a pattern of limited, probably seasonal movement along the right bank of the 20-km-long Almonda River valley, between mouth and spring, exploiting a smaller territory of approximately 300 km2 . We argue that the differences in territory size are due to an increase in population density during the Late Upper Paleolithic. [ABSTRACT FROM AUTHOR]

The Baffoni Cave is a cavern that lies in the Genga territory, in the province of Ancona, Italy. It is part of a complex of caves, the most famous of which are the Frasassi Caves. The whole territory is rich in archaeological features, with the most ancient specimen found within the Genga territory being a flint biface dating to the Lower Palaeolithic (Montanari and Pignocchi, 2022, p. 125). In 1952-1954, an archaeological expedition led by Dr Antonio Mario Radmilli searched the Baffoni Cave. Among the other specimens, three objects caught the attention of the scholar: a sandstone with signs of use, a bronze dagger and what initially appeared to be a clay mould for making unidentified metal objects.

Palaeoanthropologists and evolutionary psychologists have successfully used the increasing size of the brain during human evolution to infer cognitive and social outcomes. Archaeologists have applied similar reasoning to the development of technology in deep history. This paper goes beyond these approaches by considering the house as a metaphor for the structure of hominin minds. It is argued that the study of the mind in deep history requires, (1) a recognition that mind is distributed between bodies, brains, and the world. The implications are examined through a magnetic resonance imaging (MRI) study (that unwraps the cerebellum and which suggests that folding rather than cortex size may be more important for understanding cognition.; (2) unmasking the ingrained container- habitus that has been used to describe and investigate minds either in the present or deep past. This bias is explored by entering the eccentric house-mind of Sir John Soane (1753-1837) with its many compartments, paintings, and antiquities; and (3) an exploration of alternative embodied metaphors to enable archaeologists to study distributed mind in deep history. The metaphor ARCHITECTURE WITHOUT WALLS is discussed and briefly compared to the evidence for ‘houses’ in the Middle and Upper Pleistocene. The evidence indicates that hominins have always had complex, distributed minds but only recently in our deep history did we come to think predominantly through and with artificial containers such as houses. Late in human history these constructions became a common-sense habitus that expressed and fashioned our cognitive experience of the world.

This contribution presents a systematic and diachronic study of possible acts of cannibalism and interpersonal violence spanning from the Lower Palaeolithic to the Mesolithic period, analysing edited archaeological and anthropological data and rock art contexts. The primary objective of this critical review is to assess the existence of violence and analyse its patterns and explore its variability from the earliest forms of the genus Homo to the most recent Mesolithic hunter-gatherer groups. This study attempts a historic-religious analysis of cannibalism to evaluate the potential occurrences of ritual forms. Furthermore, the results reveal the presence of interpersonal violence, albeit with notable variations in intensity and methodology. Overall, this research equips us with valuable insights for a more profound comprehension of aggression within hunter-gatherer societies and its evolution during the Middle Pleistocene-Early Holocene.

The Bistriţa Valley is located in the north-east of Romania, crossing the entire Eastern Carpathian chain. To the Palaeolithic communities in Eastern and Central Europe, the Carpathian arc must have been a difficult obstacle to overcome. In the mountain sector of the Bistriţa Valley, the two areas of concentration of Palaeolithic settlements - the Răpciuni Basin (Ceahlău) and Bicaz-Izvorul Alb - have been variously addressed in terms of the extent of the archaeological investigations. In this study we have tried to take a different view regarding the definition and chrono-cultural sequence of Palaeolithic sites in the mountain sector of the Bistriţa Valley. The idea of the existence of an Aurignacian in this area has been abandoned, as the arguments provided by the absolute chronology definitely exclude such an assumption, whereas the occupations attributed to the Gravettian have been adapted to the sequence of this culture at Poiana Cireţului. Therefore, one may now speak of a Gravettian I and II in the Ceahlău Basin. [ABSTRACT FROM AUTHOR]

Tabun Cave, located on the slopes of Mount Carmel (Israel), constitutes one of the key Levantine Palaeolithic sites because of its exceptionally long sequence (ca. 25 m) that has yielded a suite of lithic industries spanning the Lower and Middle Palaeolithic periods. This site is also known to have produced human remains found in the Middle Palaeolithic layers: a Neanderthal female skeleton (C1), and a mandible (C2) commonly classified as Homo sapiens but whose attribution is still debated. Determining the chronology of Levantine Palaeolithic caves has often been limited by severe diagenetic processes, affecting the accuracy of age results obtained using trapped-charge dating methods. Characterising the mineralogical composition of the sediments in such conditions is an important step that was done in this study using Fourier transform infrared (FTIR) spectroscopy. We show that most of our sediment samples underwent diagenesis from the decomposition of guano, ash or bones, based on the presence of authigenic phosphates, which may impact the dose rate. Considering this information, we report here age results obtained using post-infrared infrared stimulated luminescence (pIRIR 290) of polymineral fine grains for Tabun Cave. Our pIRIR 290 ages are in overall agreement with thermoluminescence (TL) dating results obtained previously on burnt flints, reinforcing the antiquity of key transitions in the Middle Pleistocene record from Tabun Cave. The ages suggest that the Lower to Middle Palaeolithic transition at Tabun, possibly coinciding with the arrival of Homo sapiens in the Levant, may be constrained between 265 ± 26 ka (late Lower Palaeolithic, Bed 72, Unit X) and 288 ± 29 ka (early Middle Palaeolithic, Beds 63–64, Unit IX), while the age of the base of the overlying mid-Middle Palaeolithic Layer C (Unit I; Beds 22-19) ranges between 204 ± 18 ka and 192 ± 14 ka. Consequently, the Tabun C2 mandible discovered at the base of Layer C may prove to be among the oldest Homo sapiens fossils found outside Africa. [ABSTRACT FROM AUTHOR]

The dataset described in this paper presents an annotated compilation of absolute dates obtained from archaeological sites located in northern Iberia corresponding broadly to the Cantabrian region (Spain). It consists mainly of radiocarbon dates chronologically framed between 45–30 ka BP. This is the period when the last Neanderthals disappeared and the first Anatomically Modern Humans dispersed into northern Iberia, widely considered a key region for understanding the patterns and processes of this transition. Providing chronological information as well as serving as palaeodemographic proxies, this novel compilation facilitates new analyses of this key period. The dataset contains 224 dates from 37 archaeological sites and more than 87% of the dates included have been positively assessed for use. It is available at Github and linked to Zenodo with the aim to ensure accessibility, reproducibility and continued extension.

The Vârghiș Gorges karst system (Perșani Mountains, Eastern Carpathians) constituted a point of interest for speleologists, paleontologists and archaeologists since the second half of the 19th century. Their efforts succeeded in highlighting the notable archaeological potential of the area, although the actual research results were not always thoroughly reported. Since 2014, our team reunited specialists from 10 different institutions and various fields of research and initiated archaeological excavations, coupled with achaeozoological, sedimentological and chronometric investigations, in several caves within the Vârghiș Gorges. As the paper below will show, although the results obtained so far are definitively informative, further investigation are clearly needed, in order to accurately clarify aspects pertaining to the intricate cultural and chronological framework.

Recent (2006– 2009) excavations at the Palaeolithic site from La Adam Cave (central Dobrogea, south-eastern Romania) yielded numerous fossil remains, that were analysed in order to obtain more information on the Late Pleistocene faunal assemblage from the area of the cave, on the animal and anthropic contributions to bone accumulation in the cave, and on the taphonomic processes present at the site. The faunal remains analysed were highly fragmented, which prevented the precise taxonomic assessment for most of them. However, numerous specimens bear signs of chemical corrosion and carnivore bite marks, only a few showing signs of anthropic activity. The cave seems to have functioned as shelter for the carnivores, with cave bear remains dominating numerically. Other large carnivores, such as cave hyenas, most probably also contributed to bone accumulation, with large and middle-sized ruminants being their most common prey
