ABSTRACT The transition from hunting and gathering to agriculture is a major turning point in human history. In North China, although crops were cultivated as early as 10,000 BP, they only became staple foods with the establishment of a fully functional agricultural system between 6000 and 5000 BP. Thus, exploring the subsistence strategies of this transitional period is crucial for understanding how hunter‐gatherers gradually evolved into farmers. The Peiligang culture (c. 9000–7000 BP) is one of the most significant early Neolithic cultures in this region. In this study, we investigated the crust residues from the pottery Ding‐tripods (鼎) dating to the middle Peiligang culture (8800–8200 cal bp) at the Xielaozhuang site using a multidisciplinary approach that includes FTIR, XRD, SEM‐EDS, and starch granule analyses. Our results indicate that a mixture containing bone powder, Panicoideae, Triticeae, and acorns was prepared in these pottery Ding‐tripods. This finding represents one of the earliest known uses of bone powder globally, contributing valuable insights to the ongoing debate regarding fragmented bone assemblages and bone grease extraction. Moreover, combined with macrobotanical and zooarchaeological data, our findings suggest that agriculture had not yet fully supplanted hunting and gathering, as wild plants and animals continued to play a critical role in the diet at the Xielaozhuang site during the Peiligang culture. The use of bone powder alongside wild plant starches illustrates how these early communities invested significant time and effort into transforming inedible resources into consumable food, a strategy crucial for obtaining sufficient calories to sustain a sedentary lifestyle, especially during periods of resource scarcity. These insights illuminate the subsistence strategies of early Neolithic societies transitioning from reliance on hunting‐gathering to more settled practices. [ABSTRACT FROM AUTHOR]

This study investigates the impact of intraregional conflict on food security and subsistence practices in the Central Illinois River Valley (CIRV) during the Mississippian period, particularly between AD 1200 and 1400, a time characterized by escalations in intergroup violence. Utilizing integrated faunal and botanical datasets from two critical archaeological sites – the Lamb site, representing the preconflict phase, and the C. W. Cooper site, indicative of the conflict onset phase – this research elucidates how prolonged warfare necessitated substantial adaptations in subsistence strategies among CIRV Mississippian communities. While much previous research has centered on elite aspects of Mississippian warfare, this study shifts the focus to the broader societal impacts on the daily lives of residents of the CIRV. Findings demonstrate significant shifts in foraging behaviors and resource utilization patterns, reflecting strategic responses to the challenges and hazards posed by persistent warfare. By highlighting the adaptability of these communities in the face of warfare and environmental stressors, this research contributes valuable perspectives to the anthropological understanding of the interrelations between warfare and food systems.

Hunting strategies in the Paleolithic period represent a significant and complex challenge, influencing the lifestyles of early human populations dependent on the seasonal activity of herds. Varying seasonally, a composition of a herd caused changes in the speed of animals movements, their aggressiveness, hides and the fatness and flavor of their meat. The morphological criteria for determining grazer sex and age have long been established in zooarchaeology. However, many traits associated with bison sex are poorly defined for archeozoological collections due to the fragmented and scattered nature of the bone remains. The objective of presented study was to demonstrate the potential utility of proteomic tooth enamel analysis detecting the AmelX and AmelY peptide fragments for prey-sex determination in cases where morphological criteria did not work. In the study, the tooth enamel samples from 18 animals were analyzed, including eight modern specimens of known sex, and ten Pleistocene specimens of unknown sex from four different Paleolithic sites. A blind test conducted for the modern collection yielded a 100% accuracy. This outcome prompted the development of the criteria for sex determination in the bison based on proteomic analysis of tooth enamel. [ABSTRACT FROM AUTHOR]

The large number of rural Roman settlements known from the Low Countries is generally characterised by a poor preservation of ecological proxies due to the absence of waterlogged contexts. The riverside site of Wijmeers (Wichelen, Belgium), a small rural settlement located in the Lower Scheldt basin, represents a rare exception to this pattern. Due to the presence of a waterlogged sequence with Roman (late 1st–3rd centuries AD) waste layers, located only a few metres from a main building structure, and the covering of the site with alluvial sediments shortly after its abandonment, the preservation condition of charred and uncharred organic materials was exceptional. The combined study of these proxies (pollen, seeds, charcoal, mollusc shells and animal bones) presents unique insights into the subsistence economy of a Roman rural household in the Lower Scheldt valley in general, and especially its exploitation of the valley and river environments. Besides this cultural–economical perspective, the site provides key information for understanding the chronology of fluvial and alluvial processes in the Lower Scheldt Basin for a large part of the Subatlantic period (Iron Age to Early Middle Ages, ca 800 BC–900 AD).

Archaeological research in northern Sweden has customarily proposed models based on assumed migration patterns to portray resource utilization of prehistoric hunter-gatherers. An average hunting household needs about 500km2 for its subsistence. This assumption, as well as the temporal and spatial distribution of animal resources available for hunting households in the interior of Northern Sweden, is investigated using Agent Based Modelling (ABM) with explicitly identified factors and conditions. ABM simulations were run in order to analyse the relationships between hunters, moose (Alces alces), predators, landscapes and how human migration patterns could be adjusted in order to coincide with moose migrations. The results suggest that wolves and human hunters could coexist if the landscape had a moose density of 0.6 moose/km2 or more and if each hunting household possessed territories of 400–500km2. In accordance with the model’s parameters, the simulation identifies those factors that are particularly sensitive to change and those factors that are necessary in order to maintain an ecological balance between hunters and their prey.

Over the last few decades, research has significantly enhanced our understanding of the role played by shellfish in human subsistence during the Mesolithic period along the Atlantic coast of Europe. Instrumental to this advance has been the analysis of stable oxygen isotope measurements (δ18O) from mollusc shells, which offers valuable insights into the seasonality of shellfish exploitation. The δ18O values serve as reliable indicators of past seasonal seawater temperature variations experienced by the molluscs, enabling us to accurately determine the time of year when past humans collected them. Recent studies using this approach have successfully identified seasonal exploitation patterns of the topshell Phorcus lineatus (da Costa, 1778) in Atlantic Europe. However, uncertainties remain regarding the exploitation schedule of Patella depressa Pennant 1777, one of the most abundantly collected species in Mesolithic sites. Here we used shell δ18O values of P. depressa from the Mesolithic sites of El Mazo (Northern Iberia) to determine its seasonality of exploitation. Our study reveals that P. depressa was prevalently exploited during colder months. Modern specimens of the same limpet species were also collected during two annual cycles to assess potential seasonal changes in meat yield return. Results obtained has profound implications for better understanding how last coastal foragers managed available littoral resources throughout the year. [ABSTRACT FROM AUTHOR]

We can see an increasing consumption of meat together with the corresponding behavioral adaptations in early hominins, such as Homo erectus. This new development was driven by one or more behavioral adaptations, such as a shift to a higher-quality diet, increased social interactions and/or changes in the life history strategies. The methods by which these hominins obtained meat—through scavenging the carcasses of large herbivores or hunting themselves—remain a topic of debate. They seem to have thrived in expanding grasslands, which offered few resources except for herds of large, gregarious mammals. In our study, we developed an agent-based model that simulates the behavior of a group of hunter-gatherers foraging in a reconstructed tropical grassland environment. The environmental parameters, including plant availability and prey population densities, are derived from the Serengeti National Park. In this model, agents gather or hunt various species either alone or as a group, using strategies early hominins may already have access to. The basic behavior and the implemented hunting strategies are based on data from recent hunter-gatherer societies living in tropical grasslands. Our model demonstrates how foragers may have thrived in tropical grasslands by either adopting fast hunting strategies, which often require access to sophisticated hunting tools, or by cooperating extensively, which would rely on an enhanced social structure to promote cooperative behavior. Our model can be used to study other scenarios by offering the option to change the environmental conditions and aspects of the agent behavior.

In recent decades, investigations in the southern Iberian Peninsula have increased our understanding of the socio-economic impact of the spread of the Neolithic in southwestern Europe, including changes in marine resources exploitation. Nevertheless, considerable uncertainty still exists around the seasonality of such subsistence systems and the putative role of marine fish and shellfish to the evolving agro-pastoral economies. Earlier studies on the European Atlantic coast (including Iberia) have shown that the stable oxygen isotope (δ18O) values from the topshell Phorcus lineatus (da Costa, 1778) can be reliably used to derive seasonal sea surface temperatures (SST) during its lifespan. This information can be used by archaeologists to estimate the seasonality of mollusc collection in the past, and to shed light into settlement and subsistence patterns. This paper presents the results of a stable isotope study on archaeological shells of P. lineatus recovered from the Neolithic settlement of Campo de Hockey (Cádiz, Spain). We analysed shells from both funerary and residential contexts and found that P. lineatus was consumed year-round, but with a stronger preference during winter. Our results therefore contribute to advance our understanding of the role of coastal environments in early farming societies of southwestern Europe. [ABSTRACT FROM AUTHOR]

One relevant dimension through which human populations articulate their occupation of the landscape involves the accumulation and interpersonal transmission of information pertaining to the spatio-temporal distribution, accessibility, and desirability of resources. The high productivity and resource diversity of coastal circumpolar landscapes enables them to sustain larger hunter-gatherer populations throughout the year. In circumpolar landscapes, marine mammals are a particularly highly ranked resource, as major sources of essential fats, proteins, and other nutrients. The adoption of specialized toolkits for marine mammal exploitation in open waters, encompassing watercraft and detachable harpoons, would have ensured that marine mammal hunting was a particularly rewarding and predictable endeavor. The first consistent adoption of toggling harpoons in southwestern Alaska is documented primarily at the height of the cold Neoglacial (ca. 4500–2500 BP), mirroring trends along the western Bering Sea coast. While maritime resource exploitation in northwestern Alaska also appears to have begun during the Neoglacial—particularly in the Kotzebue Sound area—specialized technological adaptations reflecting full-time maritime adaptations became more prominent in the wider region during the subsequent warmer period, in the context of population growth and increasing social connectivity. In contrast, the appearance of detachable harpoons at sites in the Beagle Channel (southern Tierra del Fuego) does not appear to be associated with any significant climatic changes, developing locally around 6500 BP after an initial period of human settlement in the region which lacked such adaptations. Therefore, we argue that the pathways toward the adoption of specialized toolkits enabling a maritime-oriented subsistence strategy in circumpolar coastal environments emerged primarily as the outcome of the consolidation of knowledge networks derived from the habituation of hunter-gatherer-fisher communities to predictable ecological conditions during periods in which the coastal landscapes they inhabited had become relatively stable.

Palaeolithic sites are complex palimpsests due to the recurrent presence of human groups and carnivores through time, as documented in several European caves and rock shelters. Within these contexts, it can be challenging to identify the main contributors to bone accumulations and interpret human subsistence strategies and the role of carnivores. Consequently, taphonomic analyses are crucial for distinguishing the origins of these occupation episodes. One example of alternating occupations is found at El Castillo cave (Cantabria, Spain), specifically in the so-called Transitional Aurignacian level (∼46-42 ka uncal BP). According to a recent study conducted at this level (Luret et al., 2020), the human groups had a hunting specialisation focused on red deer, while carnivores had little influence on the assemblage. However, these interpretations were based only on the faunal assemblage from the recent excavations (1980–2011). A previous excavation phase was conducted on this site from 1910 to 1914, and after that, the faunal remains recovered were separated across several institutions, lacking a complete archaeozoological and taphonomic analysis of the whole level. In this work, a new taxonomic assessment and, for the first time, a taphonomic study of the macrofauna recovered in the Aurignacian Delta level during the initial excavations, stored at Museo Nacional y Centro de Investigación de Altamira (Cantabria, Spain), is carried out. This work provides new information about the human and carnivore groups that occupied El Castillo, constructing new hypotheses to interpret this relevant archaeological level.

Human societies face challenges in transitioning towards low‐carbon economies and sustainable management of land use and natural resources. Documenting and learning from past transitions helps policy‐makers cope with such challenges. The agricultural revolution in Cantabrian Spain (ca. 7000 cal a bp) was one major adaptation of hunter‐gatherers to a changing environment that started with the Last Glacial Maximum (ca. 24 000 cal a bp) and lasted until the Mid‐Holocene (ca. 5300 cal a bp). Classic approaches to documenting prehistoric cultural timelines are based on manufacturing and technology, thus limited in their ability to describe the sustainability of past societies. Energy regimes, a functional societal approach independent from time, investigate and consider patterns of resource and energy use in various cohabiting and cooperating cultural phases. To examine past energy regimes, a database of archaeological remains was compiled to document four indicators: mobility, economy, overexploitation and societal complexity. Statistical analyses were conducted to elucidate trends, changes and continuity in subsistence strategies by hunter‐gatherers and sedentary societies. Results show that energy regimes act as a complement to cultural phases, adding novel functional analyses of past societies to cultural stratigraphy units common in archaeology, shedding light on the sustainability of past societal transitions.

Today's image of people inhabiting the vast steppe landscapes of Mongolia is inseparably linked to mobile animal herding. Indeed, archaeologists have confirmed that humananimal communities comprised of human herders and domestic livestock roamed across Mongolia's grassland environment and utilized semi-arid to arid regions such as the Gobi steppe desert for thousands of years. However, it is much rarer to catch a glimpse of the time before the advent of pastoralism in this part of the world. During the Neolithic (ca. 6000-1800 B.C.), the Gobi was much less of a desert than it is today. Sparsely scattered archaeological sites testify to the presence of hunter-gatherer groups that successfully exploited rich wetland environments. As a result of the pedestrian survey carried out by the Dornod Mongol Survey in the greater region of Delgerkhaan Uul, we discovered in situ remains of a Neolithic habitation site. Excavations at the Margal site uncovered a stratified hearth and a lithic assemblage embedded in a habitation layer and accompanied by a few faunal bone fragments. Our finds correspond with the Oasis 2 stage (ca. 6000-3000 B.C.) of the scheme established by Janz and colleagues dividing the Mongolian Neolithic into phases based on habitation, as well as subsistence patterns and technology. However, some typical Oasis 2 markers such as pottery and grinding tools are missing from the small assemblage uncovered from test excavations in 2017 and 2018. Margal likely belonged to a regional network of extended hunter-gatherer occupation relying on wild plant and faunal resources. The site represents the first of its kind in the region and has potential to shed light on huntergatherer subsistence and habitation decisions. In concert with adjacent archaeological surface scatters and contextualized in the supraregional network of hunter-gatherer habitation, it will contribute to refining current models of lifeways and transformations in Mongolian prehistory.

The contribution of shellfish to ancient subsistence has been overlooked in many archaeological studies in Central-East Polynesia. Archaeomalacology, however, can shed light on a wider range of exploited mollusks. In this paper we investigate the exploitation of the chiton Acanthopleura gemmata from the Hane Dune site, Ua Huka, Marquesas Islands. Although several previous studies have highlighted the importance of chitons in Hane's archaeological record, little information has been presented about this important subsistence item as it is seldom identified with precision and is usually quantified by weight. Using zooarchaeological methods, spatial analysis, and biometry, we demonstrate the importance of chitons in past 'Enata subsistence. We highlight the intensive exploitation of A. gemmata during the first three centuries of occupation of the site, beginning ca. AD 950, until its abrupt depletion, correlated with the progressive exploitation of the limpet Cellana radiata. Through this case study, we stress the importance of precise taxonomic identification and refined recovery protocols to better understand subsistence trends. [ABSTRACT FROM AUTHOR]

Saint-Marcel Cave, in the terminal part of the Ardèche Gorge, is a vast karstic network, and also a key Mousterian site close to the Rhône Valley. Numerous occupations dated between the last interglacial (MIS 5e) and the end of MIS 3/beginning of MIS 2 are well documented beneath the natural porch. Recently, two discoveries of Mousterian lithic industries in the entrance gallery, 150 and 500 m from the porch, have been uncovered. They attest to deep incursions by Neanderthals into very large galleries in the karst network, at considerable distances from the daylight zone. The association of these lithic industries with Pleistocene faunal assemblages, mainly from cave bear dens, suggests that Neanderthals exploited Ursidae. These discoveries thus provide new data for understanding how these hominids adapted their subsistence economy or symbolic practices to the underground environment. Neanderthal's use and frequentation of karst networks has long been ignored due to the lack of incontrovertible evidence. The discovery of Neanderthal activity in the deep network of Bruniquel Cave (France) around -170 000 years ago shed new light on our perception of the relationship between these hominids and the underground world. The multiplication of examples of Neanderthal consumption activities and raw material exploitation (skin, bones) of large carnivores, and in particular bears, gives us fresh insights into the diversity of the behavior of these hominids and their organization. In Europe, many sites have yielded such evidence. The exploitation of large carnivores by Neanderthal thus seems much less marginal than it appeared until recently. [ABSTRACT FROM AUTHOR]

The article presents an overview of the currently available palaeoecological data on the prehistoric anthropogenic impact on the environment and emergence of farming in the south-eastern Baltic, an area poorly studied in palaeoenvironmental and archaeological terms. The recently obtained palynological data from the lake and bog sediments along with the existing archaeological finds allow us to consider several stages of prehistoric farming in the south-eastern Baltic. The first indications of forest management – the creation of open deforested areas, wood burning and probably cultivation (propagation) of hazel appear during the Mesolithic, 10 300–6500 cal BP. At about 6500–5200 cal BP, evidence of the first agricultural activity and local animal husbandry emerges. From 5200 cal BP onwards, farming probably occupies a permanent place in the subsistence strategy of the ancient population of the south-eastern Baltic.

Early Mediaeval Archaeology was long influenced by traditional narratives related to so-called Völkerwanderungen. Based on the interpretation of ancient written sources, the “Migration Period” was traditionally perceived as a time of catastrophic changes triggered by the collapse of the Western Roman Empire and massive migration waves of “barbarian” groups across Europe. In the last decades, isotope analyses have been increasingly used to test these traditional narratives by exploring past mobility patterns, shifts in dietary habits, and changes in subsistence strategies or in socio-economic structures among early medieval societies. To evaluate the achievements of isotope studies in understanding the complexity of the so-called Migration Period, this paper presents a review of 50 recent publications. Instead of re-analysing the data per se, this review first explores the potentials and limitations of the various approaches introduced in the last decades. In a second step, an analysis of the interpretations presented in the reviewed studies questions to what extend traditional expectations are supported by isotope data from the Migration Period. Beside revising the concept of massive migrations, isotope data reveal so-far underestimated mobility patterns and open new perspectives in the investigation of early medieval world.

Quantitative paleoclimate reconstructions can provide crucial climate context to test the hypothesis of climatic impact on prehistoric human activities. However, the climate change in Nenjiang River Basin is poorly understood due to the lack of reliable paleoclimate records. In this study, we report paired quantitative temperature (MAAT 0) and soil pH records based on the branched glycerol dialkyl glycerol tetraether (brGDGTs) since the mid-Holocene in an alluvial sedimentary sequence near the Honghe Neolithic site in the middle reaches of Nenjiang River Basin. The result of MAAT 0 shows an obvious cooling interval at 6.5–4.0 kyr BP, which is consistent with paleotemperature reconstruction results in EASM margin. The strengthened westerlies may play a crucial role in shaping the cooling mid-Holocene in EASM margin. The soil pH variations yield a peak at 6.0–3.5 kyr BP, which is roughly consistent with other precipitation reconstruction from northeastern China. From the middle Neolithic to Bronze period, the prehistoric humans gradually settled in Nenjiang River Basin. Cool-wet climate during 6.0–4.0 kyr BP provide enough water & wildlife resources and broader space for human survival and thus prompted the settlement and cultivation development. With the deterioration of the climate since 4.0 kyr BP, the ancient inhabitants have to move southward along the Nenjiang River to lower reaches to find more suitable places for settlement.

The mechanisms of the origin and dispersal of millet agriculture in northern China are poorly understood. We used plant macroremains, stable isotope compositions of human bone collagen, and pollen records from the Sitai site to reconstruct changes in subsistence strategies and their relationship with the ecological environment from the early to middle Holocene on the Inner Mongolian Plateau in northern China. Charred weed-like seeds, the bones of small mammals, eggshell fragments, together with microliths, indicate the practice of hunter-gatherer subsistence strategies during 10,500–10,200 cal yr BP. Deciduous broadleaved forest-steppe vegetation was present around the Sitai site during the early middle Holocene (8000–7000 cal yr BP). Additionally, isotopic compositions of human bones and plant remains reveal that millet agriculture and hunting-gathering appeared in the early middle Holocene. The spread of millet agriculture on the Inner Mongolian Plateau was likely favored by an increase in precipitation between 8000 and 7000 cal yr BP. The development of millet agriculture on the Inner Mongolia Plateau and the Loess Plateau was the prelude to its subsequent spread to the Tibet Plateau. [ABSTRACT FROM AUTHOR]

The late Early Pleistocene archaeological site of Fuente Nueva 3 (Orce, Guadix-Baza Depression, SE Spain), dated to ~1.4 Ma, provides evidence on the subsistence strategies of the first hominin population that dispersed in Western Europe. The site preserves Oldowan tool assemblages associated with abundant remains of large mammals. A small proportion of these remains show cut marks and percussion marks resulting from defleshing and bone fracturing, and a small proportion of bones also show tooth marks. Previous taphonomic studies of FN3 suggested that the hominins had secondary access to the prey leftovers abandoned by sabretooth cats and other primary predators. However, a recent analysis by Yravedra et al. (2021) of the frequency of anthropogenic marks and tooth marks has concluded that the hominins had primary access to the carcasses of a wide variety of ungulate prey, even though the frequency of evisceration marks is strikingly low. In this rebuttal, we analyse the patterns of bone preservation in FN3, which show that the exploitation of bone marrow by the hominins after hammerstone breakage was a usual activity at the site. Our study also reviews the evidence available on the lesser abilities of sabretooth cats for carcass processing compared to pantherine felids. This reinforces the hypothesis that primary predators provided the hominins the opportunity to scavenge sizeable chunks of meat and bone marrow of their prey carcasses before the arrival of hyaenas. Finally, we also provide new inferences on resource availability and competition intensity among the members of the carnivore guild in FN3, which reinforce our interpretation that a secondary access by the Oldowan hominins to the prey leftovers of sabretooth cats was an optimal foraging strategy in the Guadix-Baza Depression.

Human subsistence strategies in East Asia changed significantly during the Bronze Age. The notable spatial variability in these strategies has been mainly attributed to the asynchronous introduction and adoption of new crops and livestock, as well as climate changes. However, the impact of differential local environments on spatial patterns of subsistence strategies in diverse geomorphic areas, such as the Hengduan Mountain Region (HMR), is poorly understood. In this study, we present new carbon and nitrogen isotopic data of human bone collagen from the Adong and Gaozhai tombs in the HMR. Adong is located in a mountain area, and Gaozhai is located on a river terrace. Both sites were dated to the early third Millennium BP (before the present). Our results suggest that human diets at Gaozhai were dominated by C3 foods. Human diets at Adong, alternatively, displayed more differentiation, with greater consumption of C4 foods. Further evidence is needed to discuss the significant differences in δ15N values of human bone collagen between the Gaozhai and Adong tombs. By comparing published isotopic, archaeobotanical, and zooarchaeological data, as well as the altitude and precipitation at the archaeological sites, we propose that precipitation may have affected the diversity of human dietary strategies in the Bronze Age HMR. We conclude that at higher altitudes, humans adopted diverse subsistence strategies and obtained meat resources by hunting. Some of this preferential behavior is likely explained by the survival pressure in the highlands of the HMR during the Bronze Age.

This study examines faunal assemblages from the Proto-Zhou sites of Sunjia and Xitou, in the Jing River Valley (Central Shaanxi Province), to address questions concerning the exploitation of different animal resources in the context of the Shang-Zhou dynastic transition in the 11th century BCE. Although the assemblages from Sunjia and Xitou were small and sub-optimally preserved, this study demonstrates that the inclusion of such assemblages is essential to building upon our understanding of the human exploitation of animal resources. Our zooarchaeological analysis shows an increase in husbandry, with pig farming being complemented by extensive caprine and cattle herding. A diversified use of animal resources, and especially the larger number of bovids, could have been prompted by the need for a wider and more efficient exploitation of the immediate environment, in response to growing climatic deterioration, in addition to an increase in interactions with northern pastoral communities. Identified patterns of livestock biometry and relative taxonomic abundance show various degrees of agricultural engagement and a relatively complex livestock economy, suggesting the development of socio-economic complexity in the Jing River Valley in the late second millennium BCE.

The Holocene is defined by the impact of agricultural societies on their natural environments and resources, a paradigmatic shift triggered by the Agricultural Revolution. In Cantabrian Spain, the adoption of a sedentary economy (ca. 7000 cal yr BP) remains misunderstood, with contemporary Mesolithic and Neolithic sites apparently random dispersed. Energy Regimes, a time-independent and functional analysis of past societies, considers two cultures that cohabit and/or cooperate, based on their differential pattern of use of energy and resources, as well as on the variation in land-use strategies. We test and implement the framework of Energy Regimes through a targeted review, to examine the hunter-gatherer subsistence strategies in Cantabrian Spain. Archeological proxies such as demography, mobility, complexity of society, economy, and overexploitation of resources identified in 95 articles and books, allow us to apply Energy Regimes to reexamine transitions in hunter-gatherer societies. Neolithization in Cantabrian Spain is the result of a long process that started with the Solutrean cultural phase ca. 24,000 cal yr BP, during the Last Glacial Maximum. Hunter-gatherers developed onward novel subsistence strategies with subtle changes in energy use until the transition toward a sedentary economy. Energy Regimes provide new insights for other regional contexts where time-bounded analyses conceal the complexity of energy transition processes in Europe and beyond. [ABSTRACT FROM AUTHOR]

Whether, and in what ways, the association between changes in climate and the shifting of imperial frontiers (i.e. the Great Wall) could be mediated by the social responses of major ethnic groups is a question that remains unanswered. Ulanqab is a region in Inner Mongolia associated with a long history of Great Wall construction from the Warring States to the Ming dynasties (~500 BCE–1644 CE) and the Great Wall is often regarded as the boundary of the Central Plains dynasty. This paper uses Ulanqab as a case study to investigate the historical inter-relationship between changes in climate and subsistence strategies on the one hand, and the positioning of the Great Wall on the other. We determined the precise geographical coordinates of the Great Wall in this region during each dynastic period of Chinese history, and compared its location to (1) the empire’s boundaries in each dynasty, (2) evidence that is available on climate change from high-resolution paleo-climate reconstructions and (3) subsistence strategies (whether agriculture, pastoralism, or nomadism) that people adopted as recorded in historical documents. Geo-referenced information from associated archaeological sites was also used to determine the extent of habitation in different areas. We found that during the period of agriculturalist empires (the Han and Ming dynasties), the Great Wall was a frontier between farming and animal husbandry, and was located to the south of the Daqing Mountains. In contrast, during the period of pastoralist empires (the Zhao Kingdom [of the Warring States], Northern Wei and Jurched Jin periods), the Great Wall was the frontier between animal husbandry and nomadism, and was located to the north of the Daqing Mountains. These mountains (42.5°N) seem to have been the northern limit of human settlements that were based on animal husbandry and farming. We observed that, when precipitation and temperature increased, this resulted in an augmentation of agricultural production that most likely facilitated the northward expansion of the agriculturalist peoples. A decrease in precipitation, on the other hand, resulted in the shrinkage of pastures and food, triggering a southward expansion that was characteristic of the pastoralist peoples. This study attempts to provide new insights into the interrelationships among changes in climate, human societies and geopolitics in Chinese history. [ABSTRACT FROM AUTHOR]

The aim of this work is to examine the rodent exploitation strategies employed by the human groups that occupied the Dry Puna of Argentina during the Early and Mid-Holocene. We analyze the characteristics of the archaeological bone assemblages and present stable isotope compositions of Chinchillidae remains recovered in two Puna sites dated between 10,600–5200 years BP. Since rodent population dynamics and diets are largely reliant on local resources given their reduced spatial range, these results provide new valuable information to explore local environmental conditions in the past and how these influenced the rodent exploitation strategies employed by the hunter-gatherers that inhabited this area during the Early-Mid Holocene transition. Thus, this work presents detailed zooarchaeological data as well as δ 13C VPDB and δ 15N AIR values measured on bone collagen extracted from Lagidium sp. and other chinchillid remains recovered at Hornillos 2 and Inca Cueva 4, two archaeological sites dating to this period. These results are compared with the δ 13C VPDB and δ 15N AIR values measured on modern plants collected in the vicinity of both sites to address rodent dietary change through time as well as human procurement strategies. Our results show certain continuities for the Early-Mid Holocene transition, underlining the importance of areas such as Inca Cueva and Hornillos for past human groups, given the consistent availability of key resources for subsistence. • Past rodent exploitation strategies are studied in the Dry Puna of Argentina. • Chinchillids were an important resource during the early and mid-Holocene. • Zooarchaeology and stable isotope analysis are combined to achieve new results. • Results show continuities between early and mid-Holocene human occupations. • The areas studied were used as refugia within a changing environment.

The study of Neanderthal-Environment interactions very often lacks precise data that match the chrono-geographical frame of human activities. Here, we reconstruct Neanderthals' hunting grounds within three distinct habitats using dental microwear analysis combined with zooarchaeological data. The predation patterns toward ungulates are discussed in term of frequency (NISP/MNI) and potential meat intake (MAM). Unit IIIa of Teixoneres Cave (MIS 3, NE Spain) corresponds to a mosaic landscape, Unit IIIb was more forested, and, in the "Ensemble" II of Pié Lombard (MIS 4, SE France), forest cover dominated. At Pié Lombard, Neanderthals rely on a high diversity of taxa from closed and semi-open hunting grounds, mostly two ungulate species as well as rabbits and several bird taxa. At Teixoneres Cave, mainly open areas are exploited in summer with a predation mostly focused on large gregarious ungulates. The larger size of ungulate herds in open spaces may have allowed Neanderthals to restrict their subsistence behaviour only to very few species, in specific hunting strategies. In Unit IIIa, they do not appear to have made any selection within the most abundant species, while in Unit IIIb, they focused on aurochs and also opportunistically and heavily on newborn red deer. Neanderthal subsistence strategies seem, therefore, only partially linked to the hunting grounds they had access to. While it impacted the diversity of the prey they selected, Neanderthal groups were able to develop distinct hunting strategies within similar environments. • Confronting zooarchaeological indices and dental microwear allows the reconstruction of past human hunting grounds. • Neanderthal in open hunting grounds lead to a specialization on large gregarious ungulates. • Neanderthal predation in closed hunting grounds relies on a greater diversity of prey.

The site of Körtiktepe in southeastern Turkey is one of few sites in the Upper Mesopotamia basin that attests continuous, permanent occupation across the boundary from end of the colder, drier Younger Dryas (YD) into the comparatively wetter and warmer Early Holocene (EH). This allows for the study of the degree of environmental change experienced on a local level over this boundary as well as for the study of the adaptations that the occupants of the site undertook in response to these changes. The mammal assemblage of Körtiktepe remains relatively stable across the YD – EH transition with the main contributors to diet being mouflon (Ovis orientalis) and red deer (Cervus elaphus) in approximately the same quantities, although the contribution of aurochs (Bos primigenius) increases in the EH. The most significant changes can be seen in the shift in avifauna remains, with a sharp increase of waterbirds during the EH. It is proposed that these shifts reflect changes in the local environment with an increase in woodland cover as well as expansion of local waterways, which is generally consistent with previously published archaeobotanical studies. In terms of species exploited, mortality profiles as well as size distribution of mammals, a great deal of continuity is observed. This suggests that over this particular period the local impact of the beginning of the Early Holocene was not overly dramatic, allowing for cultural continuity of previously established subsistence strategies.

The archaeological discussion still appears to largely disregard the role of natural resources in the early agricultural economy of Central Europe. Cereal cultivation and animal husbandry strategies remain a central area of studies. Wild resources are the only proxy data helping to reconstruct the strategies mentioned above. The data for the assessment of the wild resource role in consumption strategies are scarce. Plant and animal remains preserved within the archaeological sites represent one of the very few sources of information. The dominant funeral rite – cremation – leaves no opportunity for insight into the human bones’ diet composition signatures. This study’s primary goal is to gather in one place all information concerning wild resource food use based on archaeological data, which is scattered through various publications. The study’s time scope corresponds to Lusatian, post-Lusatian (Pomeranian Face Urn Culture), and contemporary cultures (Western Baltic Kurgans Culture). It covers roughly the time span 1400–400 BC, which is the late Bronze and early Iron Ages. Only data from a homogenous settlement context was included within the presented review. Although the reviewed literature methodology does not always meet the modern standard, it still offers insight into broader plant and animal food use in the past. The animal bone analysis is usually based on hand-collected bone material or sifted soil samples. Malacological materials come from sampled features. Some clam mussels were also identified among the bone materials submitted for zooarchaeological analysis. All plant materials come from sampled features undergoing soil analysis.

The chronology and environmental context of the first hominin dispersal in Europe have been subject to debate and controversy. The oldest settlements in Eurasia (e.g., Dmanisi, ∼1.8 Ma) suggest a scenario in which the Caucasus and southern Asia were occupied ∼0.4 Ma before the first peopling of Europe. Barranco León (BL) and Fuente Nueva 3 (FN3), two Early Pleistocene archeological localities dated to ∼1.4 Ma in Orce (Guadix-Baza Depression, SE Spain), provide the oldest evidence of hominin presence in Western Europe. At these sites, huge assemblages of large mammals with evidence of butchery and marrow processing have been unearthed associated to abundant Oldowan tools and a deciduous tooth of Homo sp. in the case of BL. Here, we: (i) review the Early Pleistocene archeological sites of Europe; (ii) discuss on the subsistence strategies of these hominins, including new estimates of resource abundance for the populations of Atapuerca and Orce; (iii) use cartographic data of the sedimentary deposits for reconstructing the landscape habitable in Guadix-Baza; and (iv) calculate the size of the hominin population using an estimate of population density based on resource abundance. Our results indicate that Guadix-Baza could be home for a small hominin population of 350–280 individuals. This basin is surrounded by the highest mountainous reliefs of the Alpine-Betic orogen and shows a limited number of connecting corridors with the surrounding areas, which could have limited gene flow with other hominin populations. Isolation would eventually lead to bottlenecks, genetic drift and inbreeding depression, conditions documented in the wild dog population of the basin, which probably compromised the viability of the hominin population in the medium to long term. This explains the discontinuous nature of the archeological record in Guadix-Baza, a situation that can also be extrapolated to the scarcity of hominin settlements for these ancient chronologies in Europe.

In this study, we analyze the diet of forager–horticulturalist societies of southeast South America through different isotopic markers (δ13Ccollagen, δ13Capatite, and δ15N). The economy of these populations was based on hunting, fishing, gathering, and, to a greater or lesser extent, horticulture, showing a different emphasis on each one of these options. The samples analyzed here were recovered from different environments, including the Atlantic coast, the highlands of the Brazilian plateau, and the lowland forests of the upper valleys of the Uruguay and Paraná rivers, within a general east–west sampling transect. Most of the samples correspond to individuals recovered from the Guarani and Itararé‐Taquara archeological units. We have also included a smaller sample of foragers clustered in the so‐called Vieira Tradition, perhaps with some food production, and two individuals buried in shell mounds ("sambaquis") of the south Brazilian Atlantic coast ("Coastal Tradition"), whose economy was strongly based on marine resources and wild plants. The results indicate that, regardless of the archeological unit in question, the individuals recovered from the seashore settlements show a diet based mostly on marine protein, with a minor contribution of other resources, except in a Guarani sample, where a significant intake of maize is observed. The individuals recovered in the highlands of the Brazilian plateau ("Itararé‐Taquara") present the highest incidence of plant consumption of the entire sample analyzed, within a C3 monoisotopic pattern, probably strongly influenced by the consumption of the araucaria pine nut, and no isotopic signals related to maize intake. Guarani samples recovered from sites located in tropical forests in the interior of the continent show an unquestionable and systematic impact of maize on the diet, in addition to an important consumption of C3 animal proteins. The individuals assigned to the so‐called Vieira Tradition show a diet based on C3 protein and both C3 and C4 lipids and carbohydrates. The latter could be related to a small consumption of maize. These results demonstrate the multidirectionality of subsistence strategies in southeastern South America during the late Holocene. [ABSTRACT FROM AUTHOR]

While Etruscan sites have received considerable attention over the years, scholarly focus has rarely been directed on the faunal remains from the various celebrated archaeological localities. The present is a zooarchaeological analysis of archaeofaunal material from Gonfienti, a renowned Etruscan locality near Prato, in north-central Tuscany. The vast, complex archaeological site includes a large building, called Edifice 1, that was constructed starting from the sixth century BC. Predominant taphonomic signatures, human-induced damage, archaeobiological evidence and mortality patterns obtained from the study of the faunal remains from the building’s main phase of occupation revealed that the householders depended principally on cattle and subordinately on domestic suids for much of their subsistence, although game also formed part of the diet. The zooarchaeological interpretations match up very well with the interpretations of the excavators and archaeologists concerning the function of Edifice 1 and the use of some of its rooms. In addition, the low incidence of in situ weathering, extensive corrosion of cortical bone surfaces possibly by exposure to alkaline solutions and the relatively high frequency of waterfowls in the studied samples suggest that the area hosting Edifice 1 experienced very humid conditions and was surrounded by large wetland expanses at the time of its main Etruscan occupation.

Understanding the ways in which human groups use the environment for their survival is one of the main fields of study in Prehistory. Subsistence strategies, understood as the set of techniques, processes and activities through which human groups organise the tasks related to their survival, are a fundamental element for understanding the economic and sociocultural processes derived from these practices in the past. In this sense, archaeozoological and taphonomic studies are the main tool to reconstruct the ways in which our ancestors acquired, processed, consumed, and managed meat resources for their survival. In this research we examine the ways in which hunter-gatherer groups in the Spanish Cantabrian region exploited ungulates through a palaeoecological and palaeoeconomic analysis of a total of 32 archaeological levels at 19 sites dated between 20 and 17 ky cal BP. To this end, through research on faunal resources in this region, we will address the ways in which prey was acquired and transported, the age ranges, the seasonality of the captures and the nutritional energy contribution to the diet of the human groups, taking into account the cost of acquiring them, thus generating an updated view of subsistence strategies in the Cantabrian region. • Palaeoecological and palaeoeconomic analyses allow to determine subsistence strategies in the Lower Magdalenian. • The Magdalenian groups hunted mainly red deer, being the prey that provided the greatest amount of caloric energy. • Environment and orography of the sites, together with the search, hunting and handling time, influence the subsistence. • Magdalenian hunter-gatherers tend to hunt the most economically beneficial animals first.

Shovakh cave is a late Middle Paleolithic cave site in Northern Israel, situated ca. 8 km from the Sea of Galilee. The Cave was originally was excavated by Sally Binford in 1962, and results of the analyses of its lithic assemblages played a major role in the then-raging Bordes-Binford debate, as well as in the initiation of the field of inquires known as “technological organization.” A renewed excavation in 2016 led to a better understanding of site formation at the cave and to a refined chrono-stratigraphic framework of the Middle Paleolithic occupations at the site. Here we present the results of the analyses of lithic and faunal assemblages combining material from both the original and renewed excavations at the site. Together with the results of the geoarcheological work, we are able to offer a refined reconstruction of the modes of occupation in the site as well as of its role within late MP settlement systems in the Levant. We show that during three periods of site occupation, settlements in Shovakh were mostly ephemeral, a rare phenomenon among the late MP cave sites. At the same time, the lithic and faunal assemblages suggest that the nature of these ephemeral occupations differed temporally and spatially. In each of these cases, the fitting scenario for Shovakh’s occupations is as a “transient camp,” used over short-term occupations. [ABSTRACT FROM AUTHOR]

Excavated from 2009 to 2019 by the Tübingen-Armenian Paleolithic Project, Aghitu-3 Cave is the only stratified Upper Paleolithic site in Armenia. Sedimentary deposits range from 39,000 to 24,000 calibrated years before present (ka cal BP). The main Paleolithic occupations occurred during the accumulation of Archaeological Horizon (AH) VI between 36 and 32 ka cal BP and AH III between 29 and 24 ka cal BP. AH VI was deposited under warm and humid conditions, while AH III shows evidence for cooler and drier conditions. Here we report the results of a comprehensive zooarchaeological study aimed at characterizing early modern human hunting behavior in the Armenian Highlands. Our results indicate a focus on adult goats and equids. Bird remains are present, but we found no evidence of human exploitation. Carcass transport strategies appear more selective than those inferred for other assemblages in the region, suggesting that foragers at Aghitu-3 were exploiting larger hunting territories. Finally, we present the results of a pilot microwear and mesowear study on caprine teeth. The latter found evidence for a highly abrasive grazing diet, which in turn suggests that occupation during the formation of AH III took place in spring or summer. [ABSTRACT FROM AUTHOR]

In spite of the increased number of investigations of the Mesolithic period in Atlantic Europe, including studies that have focused on reconstructing human diets, the information about the role of shellfish in human subsistence strategies is still very limited. In this study, an experimental programme to collect modern molluscs was carried out in northern Iberia over a three-year period in order to establish the meat yield of the four main species recovered from archaeological sites in this coastal area. The resulting dataset enabled accurate estimates of the meat yield from the shell remains recovered in the shell midden deposits of El Mazo cave (Asturias, N Spain). Results show that the mollusc meat yield contributed at least 20% of the meat yield obtained from ungulates. This value is notably higher than in previous studies, showing that molluscs had a more important role in human subsistence strategies than previously recognised. The mollusc meat contribution relative to ungulates would be even higher if estimates were based on the number of identified bone remains, instead of the minimum number of individuals, which is a more subjective method and tends to overestimate the amount of mammal meat consumed by human populations. In any case, and independently of the methodology applied, our data show a greater dietary importance of shellfish during the Mesolithic than previously published for Atlantic Europe.

The lack of archaeological work has long impeded our understanding of prehistoric and historical human inhabitation and East-West interactions on the southeastern Tibetan Plateau (TP). In this study, we conducted a series of systematic archaeological investigations in the Nyingchi region, on the southeastern TP. We examined archaeological stratigraphies from 10 sites and collected charred seeds and charcoals for accelerator mass spectrometry (AMS) dating. The 26 radiocarbon dates show that the earliest inhabitation in the Nyingchi region can be traced back to as early as the fifth millennium BP. In addition, results of summed probability distribution (SPD) of radiocarbon dates suggest that intensive human activities occurred between c. 2700 and 2000 cal. yr BP. Together with the pottery net sinkers found in previous investigation, the newly identified archaeobotanical assemblages, including crops such as barley (Hordeum vulgare), naked barley (Hordeum vulgare var. nudum), wheat (Triticum aestivum) and pea (Pisum sativum), also confirm that cultivation and fishing were important subsistence strategies for people living in the prehistoric Nyingchi. The discoveries of domesticated crops from Southwest Asia also suggest that the southeastern TP, represented by the Nyingchi region, was part of the early communication network between the East and the West, predating historical Highland Silk Road.

The Neolithic period is archaeologically well documented in Central Europe, and several studies considered dietary habits and migration patterns. However, even though Switzerland and the alpine region are well known for Neolithic cultures, most of today’s knowledge about the population comes from organic materials such as wood, faunal, or botanic remains and not from the human remains themselves. This comprehensive study presents dietary reconstructions from stable isotope data (δ13C, δ15N, δ34S) of humans (n = 88) and fauna (n = 60) dating to the Neolithic from 21 sites that cluster in three main Swiss regions (Jura, Midland, Eastern Switzerland). The general data show a terrestrial C3 plant–based diet, and the δ15N values indicate regional differences between the groups, while males and females consumed similar proportions of animal proteins. It is assumed that freshwater fish was part of the diet at least in some regions. The data indicate that different subsistence strategies were practiced (animal husbandry/pastoralism vs. agriculture) possibly in relation to cultural influences. The δ34S values suggest some mobility in general, while indications for patrilocal societies are seen as females exhibit greater δ34S ranges. Overall, we conclude that most likely different subsistence strategies were practised, while no social stratigraphy based on nutritional access could be observed for the studied populations.

Objectives: This study examines long bone diaphyseal rigidity and shape of hunter‐gatherers at Roonka to make inferences about subsistence strategies and mobility of inhabitants of semi‐arid southeastern Australia. Roonka is a cemetery site adjacent to the Lower Murray River, which contains over 200 individuals buried throughout the Holocene. Archaeological evidence indicates that populations living near this river corridor employed mobile, risk averse foraging strategies. Methods: This prediction of lifestyle was tested by comparing the cross‐sectional geometric properties of the humerus, radius, ulna, femur, tibia, and fibula of individuals from Roonka to samples of varying subsistence strategies. Bilateral asymmetry of the upper limb bones was also examined. Results: Roonka males and females have moderately high lower limb diaphyseal rigidity and shape. In the upper limb, females have low rigidity and bilateral asymmetry while males have moderately high rigidity and bilateral asymmetry. This pattern is similar to other foraging groups from Australia and southern Africa that have behaviorally adapted to arid and semi‐arid environments. Discussion: Lower limb results suggest that populations in the Lower Murray River Valley had relatively elevated foraging mobility. Upper limb rigidity and bilateral asymmetry indicate a sexual division of labor at Roonka. Females resemble other samples that had mixed subsistence strategies that involved hunting, gathering, and processing tasks. Males display a pattern similar to groups that preferentially hunted large game, but that supplemented this source with smaller game and riverine resources. [ABSTRACT FROM AUTHOR]

In Part 2 of this two-part article, we further employ the lens of evolutionary medicine to explore similarities in premodern biocultural features of birth, arguing that these were an outgrowth of our common evolutionary heritage as bipedal primates. These practices grew out of the empiricism of millennia of trial and error and supported humans to give birth in closer alignment with our evolved biology. We argue that many common obstetric procedures today work against this evolved biology. In seeking to manage birth, we sometimes generate an obstetric paradox wherein we (over)intervene in human childbirth to try to keep it safe, yet thereby cause harm. We describe premodern birthing patterns in three sections: (a) eating and drinking at will and unrestrained movement in labor with upright pushing; (b) obligate midwifery and continuous labor support; and (c) the low-intervention birth/long-term breastfeeding/co-sleeping adaptive complex, and discuss how these are still relevant today. We conclude with a set of suggestions for improving the global technocratic treatment of birth and with a futuristic epilogue about a 7th, cyborgian pig that asks: What will become of birth as humans continue to coevolve with our technologies?

A multicrop agricultural system, including millet, wheat, rice, and soybeans, first emerged in China in the Late Longhang period and is considered to be one of the most important basic foundations underpinning the origin and development of early states in China. However, there is still a lack of studies on the specific subsistence strategies of humans from the Bronze Age, specifically addressing how widespread the multicrop agricultural system was. To explore these questions above, carbon and nitrogen isotope analysis on human bones from the Nanwa site (ca 1720–256 BC & 960–1279 AD) was undertaken to investigate the palaeodiet and subsistence strategies of the Nanwa humans. This paper also reviews the existing stable isotope data of Bronze Age humans on the Central Plains of China. The Nanwa humans from the Erlitou and Yinxu periods have a mean δ13C value of −9.4 ± 0.7‰ and −9.1 ± 0.9‰, suggesting a predominantly C4 diet, probably derived from millet agriculture or domesticated animals fed on millet. Nanwa humans of the Eastern Zhou Dynasty have a relatively low mean δ13C value of −10.5 ± 2.4‰, indicating a consumption of much more C3 foods, likely derived from rice, wheat, soybean, or animals that fed on those plants. A temporal stable isotopic comparison from the Erlitou period to the Eastern Zhou Dynasty on the Central Plains of China shows the majority of the Bronze Age humans have high mean δ13C value (−9.5 ± 1.8‰), suggesting a predominantly C4‐based diet. We infer that millet agriculture was still the primary economy for humans during the Bronze Age. However, there is a relatively large proportion of humans from the Eastern Zhou Dynasty that have decreased δ13C values, indicating a much more C3 foods consumption and diversity diet, presumably derived from a multicrop agricultural system of millet, wheat, rice, and soybean. It is possible that the trend moved from a narrowly focused, mainly millet‐based diet, to a more diverse agricultural system and was triggered by a combination of factors such as climate change, agricultural reform, social stratification, wars, migration, and so on.
