Article Abstract
This paper investigates the MGS1 sedimentary profile and the DGS1 sedimentary profile (37° 41'-37° 45' N, 108° 29'-108° 35' E) to analyze the mean particle size (Mz), oxides and trace elements, chemical index of alteration (CIA), scanning electron microscopy (SEM) images, and their correlation with regional Holocene climate fluctuations in the Salawusu River Basin. The results demonstrate that the chemical element variations in MGS1 and DGS1 align with the aeolian dune facies, lacustrine facies, and paleosol. The climatic information reflected by oxides like SiO and trace elements like Sr shows temporal and spatial consistency, suggesting an obvious response to desert monsoon climate changes in northern China. The Holocene climate in the Salawusu River Basin is characterized by four periods of fluctuation: early Holocene warming (11,020-10,290 Yr BP), Holocene maximum warmth (10,290-6590 Yr BP), Holocene warm-cold transition (6590-3760 Yr BP), and Holocene cold-dry climate instability (3760-0 Yr BP).

8,000 years of wild and domestic animal body size data reveal long-term synchrony and recent divergence due to intensified human impact.

The long-term evolution of domestic mammal body size in Western Europe since the Early Neolithic is mainly attributed to human selection. However, the relative influence of environmental and anthropogenic factors in animal body size evolution, and the coevolution of wild and domestic species remain poorly understood. In the Northwestern Mediterranean, abundant archaeozoological data from well-contextualized sites and reliable paleoenvironmental reconstructions provide a unique opportunity to explore long-term morphological changes and their drivers over time.

This paper presents a rare example of the multi-proxy investigation results on the prehistoric settlement from vast areas of the Mongolian Gobi Desert, where, during favorable climatic conditions, postglacial hunter-gatherer groups occupied a seasonal lake district. The geoarchaeological research conducted at site FV92, located at the Luulityn Toirom Paleolake, provides insight into the problem of human relations with the changing environment of the Early Holocene, as well as the problem of the site formation process in the Gobi area. Sedimentological studies and luminescence dating of the Luulityn Toirom Lake sediments indicate the presence of the lake and favorable environmental conditions for human settlement in the Early Holocene in the period before 8130 ± 83 BP.

The dynamics of atmospheric CO concentrations during and following the last deglaciation have mainly been ascribed to carbon release from and uptake in oceans, primarily in the Southern Ocean. But recent studies also point toward a terrestrial influence. We quantify dynamic changes to northern terrestrial carbon stocks from the Last Glacial Maximum (21,000 years) until present at millennial time steps using a combination of paleo-data and climate-biome modeling.

Scholars are increasingly favoring models for the origins of agriculture that involve a protracted process of increasing interdependence within a series of mutualistic relationships between humans and plants, as opposed to a rapid single event or innovation. Nonetheless, these scholars continue to debate over when people first started foraging for grass seeds, when they began to readily utilize sickles, how prominent the early selection pressures were, and when the first traits of domestication fully introgressed into the cultivated grass population. Here, we present complementary archaeobotanical and archaeological (stone tool) evidence for cereal foragers from Toda-1 Cave in the Surkhan Darya, dating to 9200 cal BP.
