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 . The 2011 excavation revealed 5 hominin teeth and fossil remains from 3 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dental Caries
Tooth decay, also known as cavities or caries, is the breakdown of teeth due to acids produced by bacteria. The cavities may be a number of different colors from yellow to black. Symptoms may include pain and difficulty with eating. Complications may include inflammation of the tissue around the tooth, tooth loss and infection or abscess formation. The cause of cavities is acid from bacteria dissolving the hard tissues of the teeth ( enamel, dentin and cementum). The acid is produced by the bacteria when they break down food debris or sugar on the tooth surface. Simple sugars in food are these bacteria's primary energy source and thus a diet high in simple sugar is a risk factor. If mineral breakdown is greater than build up from sources such as saliva, caries results. Risk factors include conditions that result in less saliva such as: diabetes mellitus, Sjögren syndrome and some medications. Medications that decrease saliva production include antihistamines and antide ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stalagmites
A stalagmite (, ; from the Greek , from , "dropping, trickling") is a type of rock formation that rises from the floor of a cave due to the accumulation of material deposited on the floor from ceiling drippings. Stalagmites are typically composed of calcium carbonate, but may consist of lava, mud, peat, pitch, sand, sinter, and amberat (crystallized urine of pack rats). The corresponding formation hanging down from the ceiling of a cave is a stalactite. Mnemonics have been developed for which word refers to which type of formation; one is that ''stalactite'' has a C for "ceiling", and ''stalagmite'' has a G for "ground", another is that, as with ants in the pants, the mites go up and the tights (tites) come down. Formation and type Limestone stalagmites The most common stalagmites are speleothems, which usually form in limestone caves. Stalagmite formation occurs only under certain pH conditions within the cavern. They form through deposition of calcium carbonate ...

Holocene
The Holocene ( ) is the current geological epoch. It began approximately 11,650 cal years Before Present (), after the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene has been identified with the current warm period, known as MIS 1. It is considered by some to be an interglacial period within the Pleistocene Epoch, called the Flandrian interglacial.Oxford University Press – Why Geography Matters: More Than Ever (book) – "Holocene Humanity" section https://books.google.com/books?id=7P0_sWIcBNsC The Holocene corresponds with the rapid proliferation, growth and impacts of the human species worldwide, including all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban living in the present. The human impact on modern-era Earth and its ecosystems may be considered of global si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Niah Cave
Niah National Park, located within Miri Division, Sarawak, Malaysia, is the site of the Niah Caves limestone cave and archeological site. History Alfred Russel Wallace lived for 8 months at Simunjan District with a mining engineer, Robert Coulson, who had explored what is now northern Sarawak for mineral ores. Coulson later wrote to Wallace about finding bones in a number of caves in Sarawak. On further enquiry, Wallace learned that one cave in question "was situated in the district between Sarawak and Bruni (Brunei), on a mountain some distance inland." In March 1864, Wallace favoured Coulson to explore the caves. However, later in May 1864, G. J. Ricketts, a British Consul to Sarawak was appointed to undertake the work. Ricketts did not remain in the post for long and subsequently Alfred Hart Everett was chosen to undertake the work. Everett surveyed 32 caves in three areas, including Niah/Subis (near Miri) and "Upper Sarawak Proper" (to the south of Kuching). In the 1950s ...

Xujiayao
Xujiayao, located in the Nihewan Basin in China, is an early Late Pleistocene paleoanthropological site famous for its archaic hominin fossils. Location Xujiayao is located on the west bank of the Liyi River, a tributary of the Sanggan River. Xujiayao actually consists of two sites, Locality 73113 and Locality 74093. Locality 73113 is located near Xujiayao village in Yanggao County, Shanxi, while Locality 74093 is located near Houjiayao village in Yangyuan County, Hebei. Most of the fossils and artefacts were found at Locality 74093. Discovery and excavations Xujiayao was discovered by researchers from the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) in 1974. IVPP carried out excavations in 1976, 1977, and 1979. Later excavations, in 2007 and 2008, were carried out by the Hebei Provincial Institute of Cultural Relics.

Qafzeh
Mount Precipice ( he, הר הקפיצה, "''Har HaKfitsa''"; ar, جبل القفزة, "''Jebel al-Qafzeh''", "Mount of the Leap"), also known as Mount of Precipitation, Mount of the Leap of the Lord and Mount Kedumim is located just outside the southern edge of Nazareth, 2.0 km southwest of the modern city center. It is believed by some to be the site of the Rejection of Jesus described in the Gospel of Luke (). According to the story, the people of Nazareth, not accepting Jesus as Messiah tried to push him from the mountain, but "he passed through the midst of them and went away." Archaeological excavations in the Qafzeh Cave in the mountain found human remains, whose estimated age is 100,000 years old. The human skeletons were associated with red ochre which was found only alongside the bones, suggesting that the burials were symbolic in nature. Previous to this discovery, scientists believed that human symbolic reasoning evolved much later, about 50,000 years ago. Duri ...

Neanderthals
Neanderthals (, also ''Homo neanderthalensis'' and erroneously ''Homo sapiens neanderthalensis''), also written as Neandertals, are an Extinction, extinct species or subspecies of archaic humans who lived in Eurasia until about 40,000 years ago. While the "causes of Neanderthal disappearance about 40,000 years ago remain highly contested," demographic factors such as small population size, inbreeding and genetic drift, are considered probable factors. Other scholars have proposed competitive replacement, assimilation into the modern human genome (bred into extinction), great climate change, climatic change, disease, or a combination of these factors. It is unclear when the line of Neanderthals split from that of Early modern human, modern humans; studies have produced various intervals ranging from 315,000 to more than 800,000 years ago. The date of divergence of Neanderthals from their ancestor ''Homo heidelbergensis, H. heidelbergensis'' is also unclear. The oldest potential ...

Zhiren Cave
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. Three p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
