- Analysis of 273 ancient horse genomes reveals that modern domestic horses originated in the Western Eurasian steppes, especially the lower Volga-Don region. Domestication of horses fundamentally transformed long-range mobility and warfare(1). However, modern domesticated breeds do not descend from the earliest domestic horse lineage associated with archaeological evidence of bridling, milking and corralling(2-4) at Botai, Central Asia around 3500 bc(3). Other longstanding candidate regions for horse domestication, such as Iberia(5) and Anatolia(6), have also recently been challenged. Thus, the genetic, geographic and temporal origins of modern domestic horses have remained unknown. Here we pinpoint the Western Eurasian steppes, especially the lower Volga-Don region, as the homeland of modern domestic horses. Furthermore, we map the population changes accompanying domestication from 273 ancient horse genomes. This reveals that modern domestic horses ultimately replaced almost all other local populations as they expanded rapidly across Eurasia from about 2000 bc, synchronously with equestrian material culture, including Sintashta spoke-wheeled chariots. We find that equestrianism involved strong selection for critical locomotor and behavioural adaptations at the GSDMC and ZFPM1 genes. Our results reject the commonly held association(7) between horseback riding and the massive expansion of Yamnaya steppe pastoralists into Europe around 3000 bc(8,9) driving the spread of Indo-European languages(10). This contrasts with the scenario in Asia where Indo-Iranian languages, chariots and horses spread together, following the early second millennium bc Sintashta culture(11,12).

- A collection of objects associated with prehistoric metallurgy, including casting moulds, a casting core, and a fragment of a tuyere, were found in three metallurgists’ graves in the Late Bronze Age cemetery in Legnica, south-west Poland. The finds from these graves presented an opportunity for a scientific investigation of several aspects of Bronze Age metallurgy in this region by applying various analytical procedures to characterise the remains of metals inside the casting moulds. We also analysed metal used for the repair of one of the moulds, and the razor from one of the graves that could have been cast in a mould discovered in another grave. One of the aims of this research project was to establish a possible provenance of the metal used by the population buried in these so-called metallurgists' graves using the chemical and lead isotope analysis. The casting moulds had clear wear marks providing proof of their use. In two cases, the moulds had thick greenish-black layers possibly representing remains of a corroded metal. The chemical compositions of these layers and metal from two other artefacts was investigated using ED XRF and SEM EDS. These analyses showed the diversity of the metals used for castings. Lead isotope analyses using MC ICP MS provided information about the possible origin of lead in the remains from the moulds. The most likely source of this lead is from the ores in the Erzgebirge, in eastern Germany, a few hundred kilometres south west from the site of the graves. The provenance of lead from the razor and from the repair of the mould can be either from the Erzgebirge or Slovak Ore Mountains, or a mixture of these ores. © 2022

- In the 12,000 years preceding the Industrial Revolution, human activities led to significant changes in land cover, plant and animal distributions, surface hydrology, and biochemical cycles. Earth system models suggest that this anthropogenic land cover change influenced regional and global climate. However, the representation of past land use in earth system models is currently oversimplified. As a result, there are large uncertainties in the current understanding of the past and current state of the earth system. In order to improve representation of the variety and scale of impacts that past land use had on the earth system, a global effort is underway to aggregate and synthesize archaeological and historical evidence of land use systems. Here we present a simple, hierarchical classification of land use systems designed to be used with archaeological and historical data at a global scale and a schema of codes that identify land use practices common to a range of systems, both implemented in a geospatial database. The classification scheme and database resulted from an extensive process of consultation with researchers worldwide. Our scheme is designed to deliver consistent, empirically robust data for the improvement of land use models, while simultaneously allowing for a comparative, detailed mapping of land use relevant to the needs of historical scholars. To illustrate the benefits of the classification scheme and methods for mapping historical land use, we apply it to Mesopotamia and Arabia at 6 kya (c. 4000 BCE). The scheme will be used to describe land use by the Past Global Changes (PAGES) LandCover6k working group, an international project comprised of archaeologists, historians, geographers, paleoecologists, and modelers. Beyond this, the scheme has a wide utility for creating a common language between research and policy communities, linking archaeologists with climate modelers, biodiversity conservation workers and initiatives.
