Cultural inheritance is a central issue in archaeology. If variation were not inherited, cultures could not evolve. Some archaeologists have dismissed cultural evolutionary theory in general, and the significance of inheritance specifically, substituting instead a view of culture change that results from agency and intentionality amid a range of options in terms of social identity, cultural values and behaviours. This emphasis projects the modern academic imagination onto the past. Much of the archaeological record, however, is consistent with an intergenerational inheritance process in which cultural traditions were the defining characteristics of behaviour.

As airborne lidar surveys reveal a growing sample of urbanised tropical landscapes, questions linger about the sampling bias of such research leading to inflated estimates of urban extent and population magnitude. ‘Found’ datasets from remote sensing conducted for non-archaeological purposes and thus not subject to archaeological site bias, provide an opportunity to address these concerns through pseudorandom sampling. Here, the authors present their analysis of an environmental lidar dataset from Campeche, Mexico, which reveals previously unrecorded urbanism and dense regional-scale settlement. Both characteristics, the authors argue, are therefore demonstrably ubiquitous across the central Maya Lowlands.

Classical archaeological chronologies are steeped in relative dating, but the application of absolute methods does not always support such clear-cut seriation. Here, the authors consider the significance of a Macedonian vase in reconciling the conventional and absolute chronologies of Early Iron Age Greece. Decorated with compass-drawn concentric circles and found in a Late Bronze Age context at ancient Eleon, Boeotia, the authors argue that this vessel establishes a chronological anchor and supports a twelfth-century BC emergence of the Protogeometric style in central Macedonia. A model for the indigenous development and dispersal of the Macedonian Protogeometric style is presented for future elaboration.

Substantial debate surrounds the relative lack of formal burials in Britain during the fifth century AD, which was a key period of social and economic transition following the withdrawal of the Roman army. Here, the authors argue that the ‘missing fifth century’ may be explained, in part, by the continuation of archaeologically invisible mortuary treatments practised in the preceding Iron Age and Roman period. Compilation of published radiocarbon dates from human remains found in cave and riverine contexts demonstrates that a variety of methods for the disposal of the dead—outside of formal cemeteries—existed in the first millennium AD.

The American sweet potato (Ipomoea batatas) is a globally important comestible crop that features prominently in Polynesian lore; however, the timing and mode of its Oceanic transplantation remain obscure. New research from the Māori cultivation site M24/11 in Aotearoa/New Zealand, presented here, offers a re-evaluation of evidence for the early use and distribution of the sweet potato in southern Polynesia. Consideration of plant microparticles from fourteenth-century archaeological contexts at the site indicates local cultivation of sweet potato, taro and yam. Of these, only sweet potato persisted through a post-1650 climatic downturn it seems, underscoring the enduring southern-Polynesian appeal of this hardy crop.

Investigations in the Tollense Valley in north-eastern Germany have provided evidence of a large and violent conflict in the thirteenth century BC. Typological analysis of arrowheads from the valley (10 flint and 54 bronze specimens) and comparison with type distributions in Central Europe, presented here for the first time, emphasise the supra-regional nature of the conflict. While the flint arrowheads are typical for the local Nordic Bronze Age, the bronze arrowheads show a mixture of local and non-local forms, adding to the growing evidence for a clash between local groups and at least one incoming group from southern Central Europe.

This Andean coast research has identified 113-plus geoglyphs spanning the Formative (1800–100 BC) to the Inka period (AD 1470–1532). The project combined digital technology and Remotely Piloted Airborne Systems to locate the sites. The authors also documented examples of ceramics and intricate road systems and suggest that the finds represent meticulously ritualised landscapes.

Calls for the restitution and repatriation of cultural objects continue to escalate. High-profile cases such as the Parthenon Frieze and the Benin Bronzes dominate international news cycles and provoke fierce debate; however, less attention has been paid to items that are quietly returned and to the potential positive outcomes for the institutions on both sides. This article discusses three Southeast Asian case studies to address this lacuna and urges institutions to become more proactive in their engagement with restitution and repatriation claims.

High-elevation environments present harsh challenges for the pursuit of agropastoral subsistence strategies and relatively little is known about the mechanisms early communities employed to adapt to such locations successfully. This article presents the sequential carbon and oxygen analysis of archaeological caprine teeth from Bangga (c. 3000–2200 BP), which is approximately 3750masl on the Tibetan Plateau. Made visible through this method, intra-tooth variation in isotopic composition allows insights into herding strategies that possibly included the provisioning of livestock with groundwater and agricultural fodder and summer grazing in saline or marsh environments. Such intensive provisioning differs markedly from lower-elevation agropastoralism.

A dearth of published archaeobotanical data from the Late Bronze Age of western Anatolia limits our understanding of agricultural production in this key area. Recent excavations at Çine-Tepecik provide insights into farming and the political economy in the kingdom of Mira within the lands of Arzawa. Archaeobotanical assemblages indicate that farming was structured to meet both domestic and institutional consumption; the former utilising a wide range of crop species while the latter focused on cereals. Plant remains provide further evidence for a ‘hybrid’ suite of farming practices across western Anatolia and contribute to debate around the spread of broomcorn millet cultivation.

Archaeological cultures present allegories of ethnic identities across the centuries or millennia but such conceptualisations are necessarily incomplete and lack the resolution to explore transitions between cultures. Here, exploration of the archaeological contexts, production methods, stylistic variation and radiocarbon dating of 20 preserved textile fragments facilitates an examination of cultural change at Huaca del Sol (Huacas de Moche, northern Peru). While occupants of the site experienced many outside cultural influences, including those from the highland Wari Empire, continuity in textile traditions suggests that some sense of Moche identity was maintained through the tenth century and after the perceived end of the Moche culture.

Combining non- and minimally invasive archaeological survey, geomorphological methods and linguistic studies enables a better understanding of the dynamic use of the Daugava waterway from the Bronze to the Viking ages. Results indicate a common origin period of many fortified settlements and also identify research questions about cultural fluctuations in the Baltic-Slavic–Scandinavian contact area.

Rice agriculture was brought to Japan during the first millennium BC by migrant communities of farmers from the Korean peninsula. Substantial geographic variation is observed in the uptake of this new subsistence economy, reflecting different forms of interaction between farmers and foragers. Here, the authors analyse a combination of settlement and radiocarbon data to determine the extent to which these different forms of interaction led to regional variations in population growth rate. Their results confirm the presence of different trajectories of growth, providing new insights into the diversity of demographic processes during the earliest stages of farming in Japan.

The ancient site of Nessana in the south-western Negev had an important role in the logistics of early-Christian pilgrimage to the Holy Land. The arid climate, which preserved organic material, and the richness of multilingual epigraphic evidence from this region make Nessana a key site for archaeological study of the material culture of pilgrimage.

In the ninth century AD, Moravia (now in Czechia) was the heartland of the first Slavic state-like formation in Central Europe. Traditionally, the archaeology of the region has been interpreted via historical records only; the FORMOR project aims to broaden this view by using archaeometry, archaeogenetics, bioarchaeology and introducing new theoretical approaches.

Regional variation in the historic development of agricultural societies in South-west Asia is increasingly apparent. Recent investigations at the wetland site of Balıklı (c. 8300–7900 BC) provide new insights into the initial processes of sedentism in Central Anatolia and the interaction of early communities within local and larger-scale networks. Located near major obsidian sources, excellent architectural preservation and faunal and botanical records at Balıklı suggest cultural connections to the upper Middle Euphrates region, yet inhabitants of the site do not appear to have participated in the wider South-west Asian obsidian-exchange networks and largely relied on wild resources.

The dynamics of our species’ dispersal into the Pacific remains intensely debated. The authors present archaeological investigations in the Raja Ampat Islands, north-west of New Guinea, that provide the earliest known evidence for humans arriving in the Pacific more than 55 000–50 000 years ago. Seafaring simulations demonstrate that a northern equatorial route into New Guinea via the Raja Ampat Islands was a viable dispersal corridor to Sahul at this time. Analysis of faunal remains and a resin artefact further indicates that exploitation of both rainforest and marine resources, rather than a purely maritime specialisation, was important for the adaptive success of Pacific peoples.
