The Ubaid period in south-west Asia constitutes a key period of social and political change anticipating the emergence of complex societies in the following millennium. Well-preserved archaeobotanical assemblages have enormous potential to document these changes at both the site and individual household levels. The conflagration that consumed Structure 4 at the Ubaid settlement of Kenan Tepe in south-eastern Turkey provides a case study through the analysis of almost 70 000 charred macrobotanical remains. The results suggest that labour may have been pooled between households to process emmer wheat to spikelet stage after harvesting. Final processing was conducted on the roof of the house by members of the individual household as need arose. The pooling of resources may reflect the intensification of production and the emergence of elites during the Ubaid period in this region.

The earliest tin bronze artefacts in Eurasia are generally believed to have appeared in the Near East in the early third millennium BC. Here we present tin bronze artefacts that occur far from the Near East, and in a significantly earlier period. Excavations at Pločnik, a Vinča culture site in Serbia, recovered a piece of tin bronze foil from an occupation layer dated to the mid fifth millennium BC. The discovery prompted a reassessment of 14 insufficiently contextualised early tin bronze artefacts from the Balkans. They too were found to derive from the smelting of copper-tin ores. These tin bronzes extend the record of bronze making by c. 1500 years, and challenge the conventional narrative of Eurasian metallurgical development.

Stone-built installations known as ‘leopard traps’ are found throughout the deserts of the Middle East. They have generally been considered to be recent in date, and to have been built by Bedouin or other local communities to trap carnivores that threatened their flocks. But how much older might they be? Survey in the hyper-arid ‘Uvda Valley of the southern Negev Desert in Israel discovered 23 ‘leopard traps’, 19 of them clustered in a relatively small area. This study describes the architecture and function of these structures and presents the first optically stimulated luminescence ages for two of them. These results demonstrate that the traps are ancient and were already in use before the late fourth millennium BC, not long after the adoption of herding by the desert dwellers.

The author revisits the celebrated cemetery of the Bronze Age Kerma culture by the third cataract of the Nile and re-examines its monumental tumuli. The presence of daggers and drinking vessels in secondary burials are associated with skeletal remains that can be attributed to fighting men, encouraging their interpretation as members of a warrior elite. Here, on the southern periphery of the Bronze Age world, is an echo of the aggressive aristocracy of Bronze Age Europe.

The thriving study of acoustic archaeology is here applied to an excavated plaza site in Peru, where the authors show that an intimate sound-space was intended, one which featured panpipe music as well as the spoken word. Their method involved the measurement of three sound levels of speech at various distances from the plaza, giving us an easy-to-use mode of on-site investigation, which will surely win wide application. The study also showed a dramatic change from the use of acoustics in a previous period, where sound was canalised in U-shaped temples in order to address large numbers of people.

Intriguing wooden objects, excavated (mostly unstratigraphically) from peat bogs in the Trans-Urals region of Russia, are here dated by AMS and found to belong to the Aeneolithic and Bronze Age. In spite of a long sojourn in museums, and conservation with various chemicals, the dates obtained were consistent and reliable.

High altitude snowfields provide repositories of well-preserved organic remains of considerable antiquity, as spectacular discoveries such as the Similaun Iceman illustrate. In Scandinavia, melting snow patches have been systematically surveyed by volunteer groups for almost a century, and a growing collection of archaeological artefacts has been recovered. Only recently, however, has AMS dating confirmed that some of the finds go back as far as the Neolithic. Here fragments of five Neolithic arrowshafts and a Neolithic longbow discovered in 2010–11 in the Oppdal area of Norway are described. They throw light on Neolithic bow and arrow technology and tangentially on the hunting techniques which may have attracted hunters to these snow patches in search of game. The progressive and accelerated melting of the snow patches in recent years draws attention to processes of climate change and the urgency of discovering and recovering these fragile perishable artefacts.

It has long been recognised that the proportions of Neolithic domestic animal species—cattle, pig and sheep/goat—vary from region to region, but it has hitherto been unclear how much this variability is related to cultural practices or to environmental constraints. This study uses hundreds of faunal assemblages from across Neolithic Europe to reveal the distribution of animal use between north and south, east and west. The remarkable results present us with a geography of Neolithic animal society—from the rabbit-loving Mediterranean to the beef-eaters of the north and west. They also demonstrate that the choices made by early Neolithic herders were largely determined by their environments. Cultural links appear to have played only a minor role in the species composition of early Neolithic animal societies.

When did cattle come to South Africa? Radiocarbon dates on a newly found cow horn indicates a time in the early first millennium AD. In a study of the likely context for the advent of cattle herding, the authors favour immigrants moving along a western route through Namibia.

The author shows how better recovery techniques have allowed the early history of the Mediterranean olive to be rewritten. Small scale exploitation is detectable in the Neolithic, and is widespread by the Early Bronze Age. Users appear to be first attracted by the olive wood, the fruit benefitting from the pruning effect as the olive bush becomes a tree. This process eventually results in domestication—but this is an unintended consequence of a production process driven by demand. The story now aligns better with the model put forward in Colin Renfrew's thesis of 1972.

Systematic field exploration in Tennessee has located a wealth of new rock art—some deep in caves, some in the open air. The authors show that these have a different repertoire and use of colour, and a different distribution in the landscape—the open sites up high and the caves down low. The landscape has been reorganised on cosmological terms by the pre-Columbian societies. This research offers an exemplary rationale for reading rock art beyond the image and the site.

Stable isotope analysis has provided crucial new insights into dietary change at the Neolithic transition in north-west Europe, indicating an unexpectedly sudden and radical shift from marine to terrestrial resources in coastal and island locations. Investigations of early Neolithic skeletal material from Sumburgh on Shetland, at the far-flung margins of the Neolithic world, suggest that this general pattern may mask significant subtle detail. Analysis of juvenile dentine reveals the consumption of marine foods on an occasional basis. This suggests that marine foods may have been consumed as a crucial supplementary resource in times of famine, when the newly introduced cereal crops failed to cope with the demanding climate of Shetland. This isotopic evidence is consistent with the presence of marine food debris in contemporary middens. The occasional and contingent nature of marine food consumption underlines how, even on Shetland, the shift from marine to terrestrial diet was a key element in the Neolithic transition.

The majority of the early crops grown in Europe had their origins in south-west Asia, and were part of a package of domestic plants and animals that were introduced by the first farmers. Broomcorn millet, however, offers a very different narrative, being domesticated first in China, but present in Eastern Europe apparently as early as the sixth millennium BC. Might this be evidence of long-distance contact between east and west, long before there is any other evidence for such connections? Or is the existing chronology faulty in some way? To resolve that question, 10 grains of broomcorn millet were directly dated by AMS, taking advantage of the increasing ability to date smaller and smaller samples. These showed that the millet grains were significantly younger than the contexts in which they had been found, and that the hypothesis of an early transmission of the crop from east to west could not be sustained. The importance of direct dating of crop remains such as these is underlined.

The Chengdu plain of south-west China lies outside the main centres of early domestication in the Huanghe and Yangzi valleys, but its importance in Chinese prehistory is demonstrated by the spectacular Sanxingdui bronzes of the second millennium BC and by the number of walled enclosures of the third millennium BC associated with the Baodun culture. The latter illustrate the development of social complexity. Paradoxically, however, these are not the outcome of a long settled agricultural history but appear to be associated with the movement of the first farming communities into this region. Recent excavations at the Baodun type site have recovered plant remains indicating not only the importance of rice cultivation, but also the role played by millet in the economy of these and other sites in south-west China. Rice cultivation in paddy fields was supplemented by millet cultivation in neighbouring uplands. Together they illustrate how farmers moving into this area from the Middle Yangzi adjusted their cultivation practices to adapt to their newly colonised territories.

Large curvilinear enclosures are now established as a principal instrument of human activity in Central Europe from the Neolithic into the Bronze Age (Antiquity, passim). Here the authors introduce us to examples from southern Iberia and make the case that they should be regarded as part of the same continent-wide phenomenon.

It is a pleasure to present this vivid account of elite tombs on China's Northern Frontier, together with a closely argued case for cultural hybridity within the postcolonial paradigm. This incisive exposition of political interaction on a frontier will resonate with all of us who work with ‘imperial-barbarian’ relations—on any continent.

The bronze razor with the horse-head handle appeared in Scandinavia in the fifteenth century BC. Where did it come from and what did it mean? The author shows that the razor had some antecedents in the Aegean, although none of these objects were imported to the north. He argues that the Scandinavian warrior class consciously adopted elements of the Mycenaean warrior package, including a clean-shaven face. This vividly exposes new aspects of the busy and subtle nature of international communication in the Bronze Age.

Finely crafted bronze vessels are one of the most distinctive products of early China, and illustrate the emphasis placed on formalised rituals in which these vessels are thought to have played a part. When found in graves, they have also been assumed to testify to the status of the deceased. In this study, it is shown that the repertoire of ritual vessels of bronze are often matched by similar vessels of pottery that were placed in elite graves. Together these suites of vessels indicate not only the status of the deceased but also the social standing of the mourners present during the funerary ceremonies, and in particular, perhaps, the principal heir. Funerals were occasions of ceremony and display in which both sets of vessels—bronze and pottery—may have been used by different participants, including (symbolically) the dead. Thus, early China presents another demonstration of the active and visible role that ostentatious grave goods were designed to play in the living context of funerary ceremonial. The conclusions also emphasise the greater understanding to be achieved by considering different categories of material together, rather than studying pottery and bronzes as separate domains.

The study of stable isotopes surviving in human bone is fast becoming a standard response in the analysis of cemeteries. Reviewing the state of the art for Roman Britain, the author shows clear indications of a change in diet (for the better) following the Romanisation of Iron Age Britain—including more seafood, and more nutritional variety in the towns. While samples from the bones report an average of diet over the years leading up to an individual's death, carbon and nitrogen isotope signatures taken from the teeth may have a biographical element—capturing those childhood dinners. In this way migrants have been detected—as in the likely presence of Africans in Roman York. While not unexpected, these results show the increasing power of stable isotopes to comment on populations subject to demographic pressures of every kind.

Terraced field systems are a feature of many regions of the world and have been dated as early as 6000 cal BC in the Levant (Kuijt et al. in Antiquity 81 (2007: 106–18)). The discovery of agricultural terraces in the northern Caucasus, reported here, extends their distribution into a new area. Relatively low population levels in the late medieval and early modern periods have preserved several blocks of terraced fields, some of them created at the beginning of the first millennium BC, others in the mid first millennium AD. The earlier terraced fields, associated with material and settlements of the Koban culture, culminated in over-exploitation of the land and exacerbated erosion during environmental change in the mid first millennium BC. The later series of terraced fields are of different form and are associated with the settlement in the area of communities of Alans in the first millennium AD. They largely avoided the areas rendered infertile by Koban period overexploitation. The morphology and chronology of the terraced field systems are explored using a combination of aerial photography, GIS analysis and field investigations.
