Cannabis is the world’s most-used illicit psychoactive plant, yet direct prehistoric evidence for its consumption is rare. In this study, we present the earliest direct evidence of cannabis use: offerings of plant parts and chemical compounds in ancient human hair recovered from a monumental tomb in Siberia. The findings suggest that the plant was used for its psychoactive qualities across Eurasia, where specific wild populations might have had naturally higher active compound levels. We show that the practice of cannabis consumption dates back at least 2800 years, anchoring debates around contemporary usage and informing discussions on cannabis in medicine, public health, law, and industry.

Agropastoralism has been a widespread subsistence strategy in Central Asia from prehistory to the present. While significant research has aimed at understanding past agropastoral communities in the region, reconstructing a generalized economic model remains challenging due to the complex topographic and ecological conditions, as well as its social and political variability. It is likely that subsistence strategies were flexible and adapted to local conditions. Most of what we know about these communities comes from burial sites, with comparatively less information derived from temporary encampments or occupation contexts. Caves and rockshelters have been readily used by pastoralists for millennia. In this study, we present the results of a multi‐proxy study of a Holocene sequence from one of the most archeologically significant cave sites in Central Asia: the Sel'Ungur Cave of Kyrgyzstan. We combined chronometric dating with phytolith, carpological, and fecal‐spherulite concentration analyses, as well as micromorphological, micro‐XRF, and micro‐FTIR studies. The deposits are primarily composed of charred materials and ash, forming the fumier facies. Micromorphological and micro‐analytical methods have enabled us to identify penning activities and periodic burning as the dominant site formation processes. High‐temperature burning destroyed diagnostic features necessary for more precise identification of herd animals. Notably, “vitrified” dung fragments were observed and inferred through micromorphology and micro‐XRF. Through phytolith and archaeobotanical analyses, we were able to infer that livestock mainly grazed locally. The low abundance of domesticated plants—wheat, millet, and barley—as well as fruit seeds, such as grape, pistachio, and walnut, points toward the use of these as a supplement to the herder's diet. The presence of local and allochthonous domesticated plant species alongside evidence for herding suggests the implementation of a mixed economic strategy, likely combining transhumance and agropastoralism. Chronological analysis of the fumier deposits indicates that Sel'Ungur Cave was used as a pen between the 12th and 15th centuries.

Cotton is one of the most culturally significant crops in Central Asia today, and it has a complex history, long predating the collective-labour and intensive-irrigation systems of the Soviet period. In this paper, we explore the ancient history of cotton cultivation in Central Asia. We aim to understand when cotton cultivation switched from low-investment to intensive large-scale agriculture and to theorise about the dispersal routes, type of cotton cultivated, and processing systems that existed before the introduction of hybrid forms of cotton from the Americas in the nineteenth century. We incorporate new archaeobotanical data, historical-linguistic evidence and archaeological materials into our discussion. Furthermore, we provide an overview of archaeobotanical evidence from across Europe, Asia and North Africa, aiming to assess common trends in the spread of cotton.

The Prunus genus contains many of the most economically significant arboreal crops, cultivated globally, today. Despite the economic significance of these domesticated species, the pre-cultivation ranges, processes of domestication, and routes of prehistoric dispersal for all of the economically significant species remain unresolved. Among the European plums, even the taxonomic classification has been heavily debated over the past several decades. In this manuscript, we compile archaeobotanical evidence for the most prominent large-fruiting members of Prunus, including peach, apricot, almonds, sloes, and the main plum types. By mapping out the chronology and geographic distributions of these species, we are able to discuss aspects of their domestication and dispersal more clearly, as well as identify gaps in the data and unanswered questions. We suggest that a clearer understanding of these processes will say a lot about ancient peoples, as the cultivation of delayed return crops is an indicator of a strong concept of land tenure and the specialization of these cultivation strategies seems to be tied to urbanism and reliable markets. Likewise, the evolution of domestication traits in long-generation perennials, especially within Rosaceae, represents awareness of grafting and cloning practices.

The materials of most of the archaeological sites of the Eastern Pamirs are known from lifting samples. One of them is the Kurteke rock shelter, that was discovered in 1960 by V.A. Ranov. At that time at the site there were distinguished two cultural layers dated to the Neolithic-Eneolithic and Eneolithic-Bronze period. This site is also interesting because on the walls of the rock shelter , directly above the cultural layers there are rock paintings of anthropomorphic and geometric figures. Modern data have shown that the first layer associated with the settlement of the site belongs to the final Pleistocene (older than 13 thousand years ago). In the course of the new stage of the study, palynological and carpological analysis of the soil, the study of undetectable faunal remains using the ZooMS method, and the documentation of rock carvings of the site were carried out. A comprehensive interdisciplinary study of the Kurteke materials showed that the stone industry presented here is typical of the mountainous part of Central Asia; the climate during both periods of human settlement of the site was arid, and despite the presence of cereal plants, no direct indications of their domestication were found; the faunistic composition of the site is represented by taxa typical for the territory of the Eastern Pamirs today; in the rock art there are images common in the territory of Central and Central Asia in the Bronze Age.

The Batagay mega slump is the largest active thaw slump on the planet. Enormously rapid thermal erosion gave access to permafrost sediments that deposited since the Middle Pleistocene. Permafrost is an excellent medium for the preservation of ancient organic matter. The Batagay exposure is well known for some spectacular findings of Pleistocene megaherbivore carcasses including the youngest steppe bison found in Eurasia so far, dated to 8.2 ka BP. The extraordinarily long sequence of Pleistocene deposits in Batagay is therefore an excellent archive of the palaeoenvironmental history in the Yana highlands - a region with uniquely stable cold-continental climate known as the pole of cold in the northern hemisphere. This region is regarded as refugial area for extrazonal steppe plants and now extinct large grazers together constituting the Pleistocene mammoth steppe, which covered vast areas in high and mid latitudes of the northern hemisphere during cold stages. Modern vegetation around the study site consists of light taiga mainly composed of larch, shrub alder, shrub birches and stone pine. To understand the processes that resulted in the demise of Pleistocene megafauna and in the biological turnover during the late Quaternary, we reconstructed vegetation and environmental conditions during the two climate extremes of the late Pleistocene, the onset of the last glacial maximum and the last interglacial using remains of plants and insects preserved in organic-rich material. The results from studies of plant material gathered in a fossil ground squirrel nest suggest that grassland vegetation corresponding to modern meadow steppes in Central Yakutia and northern Mongolia existed in the study area during the last cold stage. During the last interglacial, open coniferous woodland similar to modern larch taiga was the primary vegetation at the site. Abundant charcoal indicates wildfire events during the last interglacial. Zoogenic disturbances of the local vegetation were indicated by the presence of ruderal plants, especially by the abundant nitrophytic Urtica dioica, suggesting that the area was an interglacial refugium for large herbivores. Meadow steppes, which formed the primary vegetation during cold stages and provided potentially suitable pastures for herbivores, were a significant constituent of the plant cover in the Yana Highlands also under the full warm stage conditions of the last interglacial. Consequently, meadow steppes occurred in the Yana Highlands during the entire investigated timespan of the Pleistocene documenting a remarkable environmental stability. The documented fossil record also proves that modern steppe occurrences in the Yana Highlands did not establish as late as in the Holocene, as suggested by some scholars, but instead are relicts of a formerly continuous steppe belt extending from Central Siberia to Northeast Yakutia during the Pleistocene.
