Zhirendong
Zhiren Cave () is a karstic cave in the Mulan Mountains that overlooks the Hejiang River in Chongzuo, Guangxi, China. Zhiren Cave is an early Late Pleistocene site that has yielded the fossil remains of possibly anatomically modern humans with some mixed archaic human features. Fossils The fossil remains were discovered by Chinese paleontologists in 2007. The fossils were covered by a continuous layer of flowstone, a layer that was initially dated to around 113,000 to 100,000 BP. A more thorough re-dating was later undertaken, and gives an estimated date of around 116,000 to 106,000 BP. Some of the large mammal remains discovered at Zhiren Cave include those from '' Pongo pygmaeus'', ''Elephas kiangnanensis'', ''Elephas maximus'', '' Megatapirus augustus'', ''Rhinoceros sinensis'', ''Megalovis guangxiensis'', Cervus unicolor, '' Ursus thibetanus'', '' Arctonyx collaris'' and '' Panthera pardus''. Around 25% of the large mammal species discovered at the site are now extinct. Thre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Recent African Origin Of Modern Humans
In paleoanthropology, the recent African origin of modern humans, also called the "Out of Africa" theory (OOA), recent single-origin hypothesis (RSOH), replacement hypothesis, or recent African origin model (RAO), is the dominant model of the geographic origin and early migration of anatomically modern humans (''Homo sapiens''). It follows the early expansions of hominins out of Africa, accomplished by ''Homo erectus'' and then ''Homo neanderthalensis''. The model proposes a "single origin" of ''Homo sapiens'' in the taxonomic sense, precluding parallel evolution in other regions of traits considered anatomically modern, but not precluding multiple admixture between ''H. sapiens'' and archaic humans in Europe and Asia. ''H. sapiens'' most likely developed in the Horn of Africa between 300,000 and 200,000 years ago, although an alternative hypothesis argues that diverse morphological features of ''H. sapiens'' appeared locally in different parts of Africa and converged due t ...

Limestone Caves
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limestone co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caves Of Guangxi
A cave or cavern is a natural void in the ground, specifically a space large enough for a human to enter. Caves often form by the weathering of rock and often extend deep underground. The word ''cave'' can refer to smaller openings such as sea caves, rock shelters, and grottos, that extend a relatively short distance into the rock and they are called ''exogene'' caves. Caves which extend further underground than the opening is wide are called ''endogene'' caves. Speleology is the science of exploration and study of all aspects of caves and the cave environment. Visiting or exploring caves for recreation may be called ''caving'', ''potholing'', or ''spelunking''. Formation types The formation and development of caves is known as ''speleogenesis''; it can occur over the course of millions of years. Caves can range widely in size, and are formed by various geological processes. These may involve a combination of chemical processes, erosion by water, tectonic forces, microorganism ...

Archaeological Sites In China
Archaeology or archeology is the scientific study of human activity through the recovery and analysis of material culture. The archaeological record consists of artifacts, architecture, biofacts or ecofacts, sites, and cultural landscapes. Archaeology can be considered both a social science and a branch of the humanities. It is usually considered an independent academic discipline, but may also be classified as part of anthropology (in North America – the four-field approach), history or geography. Archaeologists study human prehistory and history, from the development of the first stone tools at Lomekwi in East Africa 3.3 million years ago up until recent decades. Archaeology is distinct from palaeontology, which is the study of fossil remains. Archaeology is particularly important for learning about prehistoric societies, for which, by definition, there are no written records. Prehistory includes over 99% of the human past, from the Paleolithic until the advent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fuyan Cave
Fuyan Cave () is a complex of limestone caves in Tangbei village, Lefutang town, Daoxian, Hunan province, south central China famous for the discovery of the oldest evidence for unambiguously fully modern humans outside Africa. 47 human teeth, dating to between 80,000 and 120,000 years ago, were discovered at Fuyan Cave. The teeth are also unusual for showing signs of cavities, a feature typically not found in teeth older than 50,000 years. However, a later study focusing on autosomal DNA analysis of the remains challenged this assertion, and found that the remains were younger than previously suspected. Geology Fuyan consists of three caves connected by tunnels. The cave system has a volume of and ranges over . Discovery Fuyan Cave was discovered in 1984. The cave is located at latitude 25°39′02.7″N, longitude 111°28′49.2″E, at 232 m above sea level. The cave was excavated in 2011 over an area of .
