While a clear human presence may be recognised in the Andes by 12 000–11 000 cal BP, most archaeological research has focused on occupation of the Andean highlands. To understand the initial occupation of inland areas of South America, the authors consider regional connections and spatial exploitation strategies of hunter-gatherers highlighted in a recent survey of Andean sites. Focusing on north-central Chile, artefacts and radiocarbon dates from three rock shelters suggest sporadic and brief occupation during the Terminal Pleistocene–Early Holocene. Co-occurrence of marine and montane resources, the authors argue, demonstrates a strategy of high mobility and local adaptation in early Andean occupation, using rock shelters as landmarks to navigate and learn new landscapes.

Broad cultural similarities are apparent between Neolithic sites across the Middle Nile Valley, yet local variation may also be witnessed. The dearth of well-preserved skeletal assemblages in this region means that biological connections between populations, and thus potential modes for the transmission of material culture, are not well understood. Here, the authors compare dental morphological traits in five Neolithic cemeteries (c. 5600–3800 BC) and 14 time-successive sites to explore biological relatedness along the Middle Nile Valley. Their findings parallel the artefactual evidence, suggesting that the spread of the Nubian Neolithic may have been as nuanced as the populations who practised it.

During the fourth millennium BC, public institutions developed at several large settlements across greater Mesopotamia. These are widely acknowledged as the first cities and states, yet surprisingly little is known about their emergence, functioning and demise. Here, the authors present new evidence of public institutions at the site of Shakhi Kora in the lower Sirwan/upper Diyala river valley of north-east Iraq. A sequence of four Late Chalcolithic institutional households precedes population dispersal and the apparent regional rejection of centralised social forms of organisation that were not then revisited for almost 1500 years.

Administrative innovations in South-west Asia during the fourth millennium BC, including the cylinder seals that were rolled on the earliest clay tablets, laid the foundations for proto-cuneiform script, one of the first writing systems. Seals were rich in iconography, but little research has focused on the potential influence of specific motifs on the development of the sign-based proto-cuneiform script. Here, the authors identify symbolic precursors to fundamental proto-cuneiform signs among late pre-literate seal motifs that describe the transportation of vessels and textiles, highlighting the synergy of early systems of clay-based communication.

The emergence of early cities required new agricultural practices and archaeobotanical crop-processing models have been used to investigate the social and economic organisation of urban ‘consumer’ and non-urban ‘producer’ sites. Archaeobotanical work on the Indus Valley has previously identified various interpretations of labour and subsistence practices. Here, the authors analyse a large archaeobotanical assemblage from Harappa, Pakistan (3700–1300 BC), questioning some of the assumptions of traditional crop-processing models. The ubiquity of small weed seeds, typically removed during the early stages of crop processing, is argued to result from dung burning. This additional taphonomic consideration adds nuance to the understanding of Harappa's labour organisation and food supply with implications for crop-processing models in other contexts.

Direct physical evidence for violent interpersonal conflict is seen only sporadically in the archaeological record for prehistoric Britain. Human remains from Charterhouse Warren, south-west England, therefore present a unique opportunity for the study of mass violence in the Early Bronze Age. At least 37 men, women and children were killed and butchered, their disarticulated remains thrown into a 15m-deep natural shaft in what is, most plausibly, interpreted as a single event. The authors examine the physical remains and debate the societal tensions that could motivate a level and scale of violence that is unprecedented in British prehistory.

Cuneiform tablets indicate the importance of textile manufacturing in the Bronze Age Old Assyrian Colony Period and Hittite Empire, yet the organic traces of this industry rarely survive. Two burnt textile fragments found at Beycesultan offer an unexpected insight into the Bronze Age textile industry in Anatolia. Here, the authors present the results of chromatographic and microscopic analyses that indicate one fragment was made from hemp using the nålbinding, or single-needle knitting, technique and was dyed with the woad or indigo plant, while the other was a natural tabby weave. Both add to our understanding of the diversity of textile production in the Bronze Age.

Textual sources from the Egyptian New Kingdom highlight a societal desire to preserve tombs for life after death, yet extensive architectural renovations and tomb robbing often followed the interment of elite individuals. Rather than posing a threat to conceptions of the afterlife, the author argues that these post-mortem activities were conducted with respect and the intention of forming connections. Using the identification of an unusual ritual structure from the Third Intermediate Period inside the reused Nineteenth Dynasty tomb of Paenmuaset (TT362) at Thebes (Luxor) as a basis, the author explores respect in ever-changing burial spaces as a key feature of tomb reuse.

Recent research on the organisation and growth of large settlements (both urban and non-urban) has prompted a reassessment of factors driving population aggregation. Systematic aerial and ground survey of the South Caucasus mega-fortress Dmanisis Gora, described here, contributes to the understanding of large fortress settlements in the South Caucasus (c. 1500–500 BC) as part of this wider debate. Substantial defensive walls and stone architecture in the outer settlement contrast with low-intensity occupation, possibly by a seasonally mobile segment of the population. The exceptional size of Dmanisis Gora helps add new dimensions to population aggregation models in Eurasia and beyond.

Enclosed rectangular farmsteads from the Hallstatt period in Central Europe are often cast as the seats of high-status farmers, whose land and social standing could be inherited and consolidated. Excavations at Landshut-Hascherkeller in Bavaria reveal the developmental trajectory of one such site through the stratigraphic disentanglement of its numerous ditches. Here, the authors argue that the coalescence of two rectangular farmsteads into a larger settlement complex at Hascherkeller reflects the union of neighbouring families and the resultant massing of status. The article situates this process in a segmented social system that counterpoints the typified Hallstatt hierarchy, suggesting that two social structures coexisted in the Hallstatt culture.

Salt works along the Yucatan coasts of Mexico and Belize provide a record of salt production for inland trade during the height of Late Classic Maya civilisation (AD 550–800). At the Paynes Creek Salt Works in Belize, production focused on the creation of salt cakes by boiling brine in pots supported over fires in dedicated salt kitchens. Underwater excavations at the Early Classic (AD 250–550) site of Jay-yi Nah now indicate there was a longer and evolving tradition of salt making in the area, one that initially employed large, incurved bowls to meet local or down-the-line trade needs before inland demand for salt soared.

At Ollantaytambo, in the Cusco region of Peru, the Inka (c. AD 1400–1532) built an elaborate anthropogenic landscape to facilitate intensive agriculture. After the 1532 Spanish invasion of the region, this landscape was reshaped by the introduction of new plants and animals, colonial land-management practices and demographic transformations. Here, the author employs botanical data from a derelict Inka-era reservoir to evaluate the timing and character of colonial transformations to the local agroecology. These transformations, they argue, tended towards agricultural deintensification, but this process did not begin until decades after the Spanish invasion.

Cultural landscapes affiliated with the Indigenous Sámi of the northern boreal forests are laden with cognitive elements of social and religious significance. Here, the authors focus on trees bearing incised markings and use an archaeological and ethnohistoric interpretive framework to explore the significance of such trees in Sámi landscapes. Intensive forestry is destroying culturally modified trees at an alarming rate, and their significance as the bearers of culture and history is being stripped from forest landscapes. As a step towards understanding their importance, this work makes a plea for the documentation, interpretation and protection of the remaining trees.
