The prehistoric human habitation of the Tibetan Plateau (TP) is well evidenced by the archaeological record, but poorly constrained in time and space. To test the plausibility of in situ survival during the last glacial maximum (LGM) and the coldest periods of the Pleistocene, this paper gauges the effects of LGM conditions and varying local ice coverage on the climate. Three different climate model scenarios are generated, and their outputs are used to drive vegetation simulations. This allows us to evaluate 10 archaeological sites that show evidence of human activity either pre- or post-LGM as possible human refugia. The results show that the higher the level of ice coverage on the plateau, the colder and drier the climate becomes, and barren unproductive land extends farther south. However, there are sites that remain habitable in all scenarios, with the southern and northeastern plateau identified as the areas with the highest likelihood of refugia during the LGM, specifically at the locations of Baishiya Karst Cave and Siling Co. There is a high probability of the TP being habitable during the LGM, as even the scenario with the most ice yields some regions with favourable conditions that are within the habitability criteria.

Mandibular and dental material of hyaenids from the Central Asian localities of Zasukhino-3 (Russia) and Nalaikha (Mongolia), dating to the late Early Pleistocene (0.9–0.78 Ma) was identified as giant hyena Pachycrocuta brevirostris based on morphological and size similarities. Comparative analysis of Eurasian P. brevirostris from different stratigraphic levels (from 2.1 to 0.5 Ma) revealed two evolutionary stages of the lower cheek teeth of the giant hyenas. The stages are determined as morphotypes A and B, directed toward the differentiation of the function of premolar and enhancing the cutting function of m1. We traced the microprocesses that occurred during the transition from the primitive structure of the m1 talonid to its more advanced state. This event occurred during the transition from the late Villafranchian to the Epivillafranchian (ca. 1.1–0.9 Ma). The stabilized advanced morphotype B was found in samples from Zasukhino-3, Nalaikha, and other close-in-age localities such as Lakhuti-2. The new finds from Asian Russia and Mongolia suggest that P. brevirostris from these regions represent a single giant hyena population occupying the northernmost part of their Asian range.

Fields of sandy paleodunes have been identified in Brazil, Colombia, Venezuela, and Guyana north of the South American continent. In this study, geochronological data obtained by optically stimulated luminescence (OSL) for paleodunes in the Middle Rio Negro region (Brazil) allowed the identification of two stages of dune deposition: the older from 169.74 ± 1.01 ka to 124.38 ± 0.91 ka and the younger from 18.89 ± 0.88 ka to 14.75 ± 0.77 ka. The older interval is the first reported in the Amazon; no correlated sediment has been documented. In contrast, the more recent depositional interval correlates to the interval of paleodune fields of the region called “dry corridor” in the Late Pleistocene–Holocene. In this study, we associated the genesis of paleodunes with the reworking of alluvial deposits from the Negro and Demini rivers, driven by river seasonality during the Pleistocene–Holocene, as evidenced by characteristic microtextural data.

This article analyses the fanghuiju 访惠聚 campaign as a core component of grassroots governance in Xinjiang. It traces its evolution from Mao-era mobilization practices to a systematized mechanism of authoritarian control in the Xi Jinping era. Moving beyond institutional and security-centric frameworks, the study situates fanghuiju as a regionally initiated, localized adaptation by the Xinjiang government and grassroots cadres that blends revolutionary traditions in China with contemporary innovations in surveillance, personalized datafication and ideological governance. Drawing on state media, policy documents and extensive analysis of work team literature, this paper argues that fanghuiju work teams represent a localized fusion of Maoist mobilization and Xi-era high-tech governance. They function as tools for grassroots surveillance, political indoctrination and socio-economic restructuring, marking a shift from episodic campaigns to permanent, embedded governance that blends top-down control with bottom-up engagement.

Since its rediscovery in the context of nineteenth-century colonial India, the study of the ancient Buddhist sculpture of Gandhara (northern Pakistan) has been hampered by very limited information about the provenance of finds. This is the result of poorly documented expeditions by archaeologists and antiquarians, as much as the enduring appeal of classically-influenced Gandharan art to collectors. The present study casts light on the modern itineraries of antiquities recovered on the North-West Frontier of late colonial India with new discoveries about the extraordinary Evert Barger expedition of 1938.

Although it made a major contribution to the collections of the Victoria and Albert Museum in London, its nominal sponsor, the Barger expedition was characterised by a surprisingly haphazard and unstrategic approach, even by the standards of the day, and it straddled the diplomatically sensitive boundary between the official jurisdiction of British India and the princely state of Swat. By exploring new information about three Barger sculptures in the Ashmolean Museum in Oxford, two of which were previously unprovenanced, this study unpacks the complex history of the Barger antiquities, correcting past misapprehensions and adding depth to a story of colonial archaeology that has tended to rely on generalisations.

Panoramic accounts of long-term socio-political change tend to marginalize the role of animals. Taking a materialist stance, we re-evaluate the ways livestock shaped the emergence of the tributary mode of production out of a kinship-ordered mode of production. This explicitly Marxist analytical framework foregrounds the interplay between value, wealth, and labour, while attending to the economic specificities of livestock that make it particularly dynamic. Drawing on ethnohistorical data, we identify wealth in livestock as heritable, expandable, flexible, and convertible, while inherently unstable. We offer the first synthesis tying these qualities together and present a holistic picture of how these qualities can catalyse the class formation by promoting differential accumulation of wealth, economic growth, and direct appropriation of value from producers. These dynamics offer an animal-centric explanatory lens to view the long-term trajectory of northern Mesopotamia from the Neolithic through the Late Chalcolithic (9700-3500 BCE), where caprines, cattle, and pigs were central to the development of urbanism and states. While our analysis is specific to the social formations, species, and human-animal relations in northern Mesopotamia, the framework we present can be applied to contexts globally to better understand the animal side of political economic dynamics of early complex societies.

The capacity to relate a signal to an arbitrary, specific and generally understood meaning—symbolism—is an integral feature of human language. Here, we explore two aspects of knapping technology at the Acheulean site of Boxgrove that may suggest symbolic communication. Tranchet tips are a difficult handaxe form to create, but are unusually prevalent at Boxgrove. We use geometric morphometrics to show that despite tranchet flaking increasing planform irregularity, handaxes with tranchet tips have more standardized 3D shapes than those without. This challenging standardization suggests tranchet tips at Boxgrove were part of a normative prescription for a particular handaxe form. Boxgrove presents some of the thinnest handaxes in the Acheulean world. To replicate such thin bifaces involves the technique of turning-the-edge. Since this technique is visually and causally opaque it may not be possible to learn through observation or even pointing, instead requiring arbitrary referents to teach naïve knappers. We use scar ordering on handaxes to show a variety of instances of turning-the-edge in different depositional units at Boxgrove, indicating it was socially transmitted to multiple knappers. The presence of societally understood norms, coupled with a technique that requires specific referents to teach its salient features, suggests symbolism was a feature of hominin communication at Boxgrove 480,000 years ago.

John Carter’s fervour as a recorder and polemicist for Gothic architecture has been debated since his lifetime, but his classical designs have attracted less interest. However, these give some insight into the influences upon aspiring young Georgian architects, as Carter was in the 1770s. His two sets of designs for Bywell Hall, Northumberland, the first published in the Builder’s Magazine in 1776, and a more detailed portfolio now in a private collection, are presented together for the first time. This is an opportunity to examine Carter’s early ideas and his thoughts on the appropriate styles to be employed for public, domestic and ecclesiastical buildings. Analysis of Carter’s designs demonstrates his desire to create impressive interior spaces, but poor consideration of the practicalities for family and servant life in country houses. Carter’s preference for Gothic over classical architecture, combined with humble origins and personality traits, prevented his aspiration to be an architect, but his drawing skills secured fame as one of the foremost architectural draughtsmen.

The nexus of artificial intelligence (AI) and memory is typically theorized as a ‘hybrid’ or ‘symbiosis’ between humans and machines. The dangers related to this nexus are subsequently imagined as tilting the power balance between its two components, such that humanity loses control over its perception of the past to the machines. In this article, I propose a new interpretation: AI, I posit, is not merely a non-human agency that changes mnemonic processes, but rather a window through which the past itself gains agency and extends into the present. This interpretation holds two advantages. First, it reveals the full scope of the AI–memory nexus. If AI is an interactive extension of the past, rather than a technology acting upon it, every application of it constitutes an act of memory. Second, rather than locating AI’s power along familiar axes – between humans and machines, or among competing social groups – it reveals a temporal axis of power: between the present and the past. In the article’s final section, I illustrate the utility of this approach by applying it to the legal system’s increasing dependence on machines, which, I claim, represents not just a technical but a mnemonic shift, where the present is increasingly falling under the dominion of the past – embodied by AI.

The Đurđevac Sands constitute a wide area of small-scale dune relief in the Podravina (NE Croatia), located along the central part of the southern Drava River valley. Even though it has been the subject of earlier investigations, the timing and characteristics of aeolian activity and pedogenesis remain unclear. In this study, field investigations and laboratory methods are combined to gather information on past aeolian systems in the southern part of the Pannonian Basin. The results indicate that weak soil formation during the Bølling-Allerød interstadial stabilized the dunes after the first episode of aeolian activity that took place since ca. 18 ka. The source material for dune building is thought to be fluvial sand from the Drava River, which was blown from exposed terraces. During the Younger Dryas and/or Early Holocene, a new phase of aeolian activity is recorded, with material showing stronger evidence of weathering compared to the underlying aeolian material. Finally, during the Mid and/or Late Holocene, dunes were overbuilt once again with fresh unweathered sand. In general, these new findings obtained from the Đurđevac Sands area correlate rather well with other regions in the Pannonian Basin, in terms of the timing and characteristics of soil formation and aeolian activity.
