Abstract It has long been believed that climate shifts during the last 2 million years had a pivotal role in evolution of our genus Homo 1–3 . However, given limited number representative palaeo-climate datasets from regions anthropological interest, it remained challenging to quantify this linkage. Here, we use an unprecedented transient Pleistocene coupled general circulation model simulation combination with extensive compilation fossil and archaeological records study spatiotemporal...
The relationship between initial
To investigate the role of vegetation and ecosystem diversity on hominin adaptation migration, we identify past human habitat preferences over time using a transient 3-million-year earth system-biome model simulation an extensive fossil archaeological database. Our analysis shows that early African hominins predominantly lived in open environments such as grassland dry shrubland. Migrating into Eurasia, adapted to broader range biomes time. By linking location age sites with corresponding...
We identify past human habitat preferences over time to investigate the role of vegetation and ecosystem diversity on hominin adaptation migration. Using a transient 3-million-year earth system-biome model simulation an extensive fossil archaeological database we distinguish in what previous Hominin lived. Our analysis shows that early African hominins predominantly lived open environments such as grassland dry shrubland. Hominins adapted broader range biomes by migrating into Eurasia. By...
Abstract. Palaeoclimate information on multiple climate variables at different spatiotemporal scales is becoming increasingly important to understand environmental and societal responses change. A lack of high-quality reconstructions past hydroclimate has recently been identified as a critical research gap. Speleothems, with their precise chronologies, widespread distribution, ability record changes in local regional variability, are an ideal source such information. Here, we present new...
Abstract. Middle Holocene cultures have been widely studied around the Eastern-Mediterranean basin in last 30 years and past cultural activities commonly linked with regional climate changes. However, many cases such linkage is equivocal, part due to existing climatic evidence that has derived from areas outside distribution of ancient settlements, leading uncertainty complex spatial heterogeneity both demography. A few high-resolution well-dated paleoclimate records were recently...
Abstract The progress of science is tied to the standardization measurements, instruments, and data. This especially true in Big Data age, where analyzing large data volumes critically hinges on being standardized. Accordingly, lack community‐sanctioned standards paleoclimatology has largely precluded benefits advances field. Building upon recent efforts standardize format terminology paleoclimate data, this article describes Paleoclimate Community reporTing Standard (PaCTS), a crowdsourced...
When, where, and how often hominin interbreeding happened is largely unknown. We study the potential for Neanderthal-Denisovan admixture using species distribution models that integrate extensive fossil, archaeological, genetic data with transient coupled general circulation model simulations of global climate biomes. Our Pleistocene hindcast past hominins' habitat suitability reveals pronounced climate-driven zonal shifts in main overlap region Denisovans Neanderthals central Eurasia. These...
Smart contracts, as one of the important applications blockchain technology, provide possibility for automated execution payment systems. This article explores an algorithm smart contracts in systems based on and big data technology to address issues low accuracy efficiency contract execution. utilizes immutability decentralization features ensure security transparency transactions. At same time, combined with powerful analytical capabilities data, deep mining transaction is carried out...
The Late Quaternary period was characterized by the widespread extinction of over 50% global megafaunal species, followed a rapid decline in biodiversity. relative roles adverse climatic conditions and emergence modern humans these extinctions remain unresolved due to sparsity palaeoecological evidence. Here we present new spatially explicit dynamical model (ICCP Global Mammal Model, IGMM) that simulates climate-induced changes habitat suitability biomass distribution more than 2000...
Mid-Pleistocene transition (MPT), a climate state underwent low temperature and dry condition, has been suggested as candidate for massive genomic bottleneck in African hominins ~0.9 million years ago (Ma). However, no sufficient evidence supports such attribution to deterioration the human genetic bottleneck. Here, we use an agent-based model forced by realistic time-evolving conditions investigate population changes of hominins. With our climate-driven simulations, collapses are found...
Abstract Chinese speleothem oxygen isotope (δ 18 O) variations have been widely interpreted as recording the evolution of Asian Monsoon. However, calibration δ O to monsoon intensity has not yet carried out in a quantitative way. To understand climatic significance O, we measured monthly precipitation data at Heshang Cave, China, where records were previously obtained. We examined influence local climate and large‐scale atmospheric circulation on by correlating meteorological various...

Abstract Characterization of moisture origins is crucial to understanding hydroclimatic processes. Nevertheless, documenting past atmospheric contents and their sources remains challenging partially due insufficient moisture-tracing proxies. Here, we present triple oxygen isotope compositions in 21 cave speleothems from monsoonal Asia examine spatial origin differences eastern over the 300 years. Our data suggest an isotopic equilibrium fractionation during speleothem formation, thus parent...
Abstract Understanding the hydrological processes of colloids within karst vadose zone is vital to security groundwater and providing appropriate paleohydrological explanations colloid‐facilitated metals in speleothem. This study addresses mobilization mechanisms driving colloidal organic matter (COM) transport using a 15‐year long monthly monitoring dataset from cave drip point (HS4) Heshang Cave, Qingjiang Valley, China. Variations COM concentrations were reported as fluorescence...
