World Heritage Site
–
A World Heritage Site is a landmark which has been officially recognized by the United Nations, specifically by the United Nations Educational, Scientific and Cultural Organization. Sites are selected on the basis of having cultural, historical, scientific or some form of significance. UNESCO regards these sites as being important to the interests of humanity. The programme catalogues, names, and conserves sites of outstanding cultural or natural importance to the common culture, under certain conditions, listed sites can obtain funds from the World Heritage Fund. The program was founded with the Convention Concerning the Protection of the Worlds Cultural and Natural Heritage, since then,192 state parties have ratified the convention, making it one of the most adhered to international instruments. As of July 2016,1052 sites are listed,814 cultural,203 natural, in 1959, the governments of Egypt and Sudan requested UNESCO to assist their countries to protect and rescue the endangered monuments and sites. In 1960, the Director-General of UNESCO launched an appeal to the Member States for an International Campaign to Save the Monuments of Nubia, the campaign, which ended in 1980, was considered a success. The project cost $80 million, about $40 million of which was collected from 50 countries, the projects success led to other safeguarding campaigns, saving Venice and its lagoon in Italy, the ruins of Mohenjo-daro in Pakistan, and the Borobodur Temple Compounds in Indonesia. UNESCO then initiated, with the International Council on Monuments and Sites, the United States initiated the idea of cultural conservation with nature conservation. The International Union for Conservation of Nature developed similar proposals in 1968, the Convention came into force on 17 December 1975. As of June 2016, it has been ratified by 192 states, including 188 UN member states plus the Cook Islands, the Holy See, Niue, a country must first list its significant cultural and natural sites, the result is called the Tentative List. A country may not nominate sites that have not been first included on the Tentative List, next, it can place sites selected from that list into a Nomination File. The Nomination File is evaluated by the International Council on Monuments and Sites and these bodies then make their recommendations to the World Heritage Committee. There are ten selection criteria – a site must meet at least one of them to be included on the list, up to 2004, there were six criteria for cultural heritage and four criteria for natural heritage. In 2005, this was modified so there is now only one set of ten criteria. Nominated sites must be of outstanding value and meet at least one of the ten criteria. Thus, the Geneva Convention treaty promulgates, Article 53, PROTECTION OF CULTURAL OBJECTS AND OF PLACES OF WORSHIP. There are 1,052 World Heritage Sites located in 165 States Party, of these,814 are cultural,203 are natural and 35 are mixed properties

Geographic coordinate system
–
A geographic coordinate system is a coordinate system used in geography that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are chosen such that one of the numbers represents a vertical position. A common choice of coordinates is latitude, longitude and elevation, to specify a location on a two-dimensional map requires a map projection. The invention of a coordinate system is generally credited to Eratosthenes of Cyrene. Ptolemy credited him with the adoption of longitude and latitude. Ptolemys 2nd-century Geography used the prime meridian but measured latitude from the equator instead. Mathematical cartography resumed in Europe following Maximus Planudes recovery of Ptolemys text a little before 1300, in 1884, the United States hosted the International Meridian Conference, attended by representatives from twenty-five nations. Twenty-two of them agreed to adopt the longitude of the Royal Observatory in Greenwich, the Dominican Republic voted against the motion, while France and Brazil abstained. France adopted Greenwich Mean Time in place of local determinations by the Paris Observatory in 1911, the latitude of a point on Earths surface is the angle between the equatorial plane and the straight line that passes through that point and through the center of the Earth. Lines joining points of the same latitude trace circles on the surface of Earth called parallels, as they are parallel to the equator, the north pole is 90° N, the south pole is 90° S. The 0° parallel of latitude is designated the equator, the plane of all geographic coordinate systems. The equator divides the globe into Northern and Southern Hemispheres, the longitude of a point on Earths surface is the angle east or west of a reference meridian to another meridian that passes through that point. All meridians are halves of great ellipses, which converge at the north and south poles, the prime meridian determines the proper Eastern and Western Hemispheres, although maps often divide these hemispheres further west in order to keep the Old World on a single side. The antipodal meridian of Greenwich is both 180°W and 180°E, the combination of these two components specifies the position of any location on the surface of Earth, without consideration of altitude or depth. The grid formed by lines of latitude and longitude is known as a graticule, the origin/zero point of this system is located in the Gulf of Guinea about 625 km south of Tema, Ghana. To completely specify a location of a feature on, in, or above Earth. Earth is not a sphere, but a shape approximating a biaxial ellipsoid. It is nearly spherical, but has an equatorial bulge making the radius at the equator about 0. 3% larger than the radius measured through the poles, the shorter axis approximately coincides with the axis of rotation

Cave
–
A cave is a hollow place in the ground, specifically a natural underground space large enough for a human to enter. Caves form naturally by the weathering of rock and often extend deep underground, the word cave can also refer to much smaller openings such as sea caves, rock shelters, and grottos. A cavern is a type of cave, naturally formed in soluble rock with the ability to grow speleothems. Speleology is the science of exploration and study of all aspects of caves, visiting or exploring caves for recreation may be called caving, potholing, or spelunking. The formation and development of caves is known as speleogenesis, which can occur over the course of millions of years, caves are formed by various geologic processes and can be variable sizes. These may involve a combination of processes, erosion from water, tectonic forces, microorganisms, pressure. Isotopic dating techniques can be applied to cave sediments, in order to determine the timescale when geologic events may have occurred to help form and it is estimated that the maximum depth of a cave cannot be more than 3,000 metres due to the pressure of overlying rocks. For karst caves the maximum depth is determined on the basis of the limit of karst forming processes. Most caves are formed in limestone by dissolution, solutional caves or karst caves are the most frequently occurring caves and such caves form in rock that is soluble. Most occur in limestone, but they can form in other rocks including chalk, dolomite, marble, salt. Rock is dissolved by acid in groundwater that seeps through bedding planes, faults, joints. Over geological epochs cracks expand to become caves and cave systems, the largest and most abundant solutional caves are located in limestone. Limestone dissolves under the action of rainwater and groundwater charged with H2CO3, the dissolution process produces a distinctive landform known as karst, characterized by sinkholes and underground drainage. Limestone caves are often adorned with calcium carbonate formations produced through slow precipitation and these include flowstones, stalactites, stalagmites, helictites, soda straws and columns. These secondary mineral deposits in caves are called speleothems, the portions of a solutional cave that are below the water table or the local level of the groundwater will be flooded. Lechuguilla Cave in New Mexico and nearby Carlsbad Cavern are now believed to be examples of type of solutional cave. They were formed by H2S gas rising from below, where reservoirs of oil give off sulfurous fumes and this gas mixes with ground water and forms H2SO4. The acid then dissolves the limestone from below, rather than from above, caves formed at the same time as the surrounding rock are called primary caves

Cave painting
–
Cave paintings are painted drawings on cave walls or ceilings, mainly of prehistoric origin, to some 40,000 years ago in Eurasia. The exact purpose of the Paleolithic cave paintings is not known, evidence suggests that they were not merely decorations of living areas since the caves in which they have been found do not have signs of ongoing habitation. They are also located in areas of caves that are not easily accessible. Some theories hold that cave paintings may have been a way of communicating with others, the paintings are remarkably similar around the world, with animals being common subjects that give the most impressive images. Humans mainly appear as images of hands, mostly hand stencils made by blowing pigment on a hand held to the wall. The earliest known cave paintings/drawings of animals are at least 35,000 years old and are found in Pettakere cave on the island of Sulawesi in Indonesia, previously it was believed that the earliest paintings were in Europe. The earliest non-figurative rock art dates back to approximately 40,000 years ago, nearly 340 caves have now been discovered in France and Spain that contain art from prehistoric times. But subsequent technology has made it possible to date the paintings by sampling the pigment itself, the choice of subject matter can also indicate chronology. For instance, the reindeer depicted in the Spanish cave of Cueva de las Monedas places the drawings in the last Ice Age. The oldest date given to a cave painting is now a pig that has a minimum age of 35,400 years old at Pettakere cave in Sulawesi. Indonesian and Australian scientists have dated other non-figurative paintings on the walls to be approximately 40,000 years old, the method they used to confirm this was dating the age of the stalactites that formed over the top of the paintings. The art is similar in style and method to that of the Indonesian caves as there were also hand stencils and this date coincides with the earliest known evidence for Homo sapiens in Europe. Because of the cave arts age, some scientists have conjectured that the paintings may have made by Neanderthals. The earliest known European figurative cave paintings are those of Chauvet Cave in France and these paintings date to earlier than 30,000 BCE according to radiocarbon dating. Some researchers believe the drawings are too advanced for this era, the radiocarbon dates from these samples show that there were two periods of creation in Chauvet,35,000 years ago and 30,000 years ago. In 2009, cavers discovered drawings in Coliboaia Cave in Romania, an initial dating puts the age of an image in the same range as Chauvet, about 32,000 years old. Some caves probably continued to be painted over a period of thousands of years. This was created roughly between 10,000 and 5,500 years ago, and painted in rock shelters under cliffs or shallow caves, though individual figures are less naturalistic, they are grouped in coherent grouped compositions to a much greater degree

Upper Paleolithic
–
The Upper Paleolithic is the third and last subdivision of the Paleolithic or Old Stone Age. Very broadly, it dates to between 50,000 and 10,000 years ago, roughly coinciding with the appearance of behavioral modernity, modern humans are believed to have emerged about 195,000 years ago in Africa. Although these humans were modern in anatomy, their lifestyle changed very little from their contemporaries, such as Homo erectus, about 50,000 years ago, there was a marked increase in the diversity of artifacts. In Africa, bone artifacts and the first art appear in the archeological record, between 45,000 and 43,000 years ago, this new tool technology spread with human migration to Europe. The new technology generated an explosion of modern humans which is believed to have contributed to the extinction of the Neanderthals. The Upper Paleolithic has the earliest known evidence of organized settlements, in the form of campsites, artistic work blossomed, with cave painting, petroglyphs, carvings and engravings on bone or ivory. The first evidence of fishing is also noted, from artifacts in places such as Blombos cave in South Africa. More complex social groupings emerged, supported by more varied and reliable food sources and this probably contributed to increasing group identification or ethnicity. By 50, 000–40,000 BP, the first humans set foot in Australia, by 45,000 BP, humans lived at 61° north latitude in Europe. By 30,000 BP, Japan was reached, and by 27,000 BP humans were present in Siberia above the Arctic Circle, at the end of the Upper Paleolithic, a group of humans crossed the Bering land bridge and quickly expanded throughout North and South America. Both Homo erectus and Neanderthals used the same crude stone tools, archaeologist Richard G. Klein, who has worked extensively on ancient stone tools, describes the stone tool kit of archaic hominids as impossible to categorize. It was as if the Neanderthals made stone tools, and were not much concerned about their final forms and he argues that almost everywhere, whether Asia, Africa or Europe, before 50,000 years ago all the stone tools are much alike and unsophisticated. These new stone-tool types have been described as being distinctly differentiated from each other, the invaders, commonly referred to as the Cro-Magnons, left many sophisticated stone tools, carved and engraved pieces on bone, ivory and antler, cave paintings and Venus figurines. The Neanderthals continued to use Mousterian stone tool technology and possibly Chatelperronian technology and these tools disappeared from the archeological record at around the same time the Neanderthals themselves disappeared from the fossil record, about 40,000 years ago. Settlements were often located in valley bottoms, possibly associated with hunting of passing herds of animals. Hunting was important, and caribou/wild reindeer may well be the species of single greatest importance in the anthropological literature on hunting. Technological advances included significant developments in flint tool manufacturing, with industries based on fine blades rather than simpler and shorter flakes, burins and racloirs were used to work bone, antler and hides. Advanced darts and harpoons also appear in period, along with the fish hook, the oil lamp, rope

Vallon-Pont-d'Arc
–
Vallon-Pont-dArc is a commune in the Ardèche department in southern France. Vallon-Pont-dArc is a capital of prehistoric and cultural tourism and this small village, peaceful in wintertime, sees its population expand ten-fold in summer. Its tourist importance largely comes from the fact that it is the point for the river descent of the Gorges de lArdèche. Vallon-Pont-dArc is situated at the threshold of one of the most beautiful tourist sites of France, the famous Pont dArc, a natural arch of more than 30 metres height, carved out by the Ardèche and classified as a Great Site of France, gave it its name. 1.8 km southeast of the village, the River Ibie flows into the Ardèche,1801, Saint-Martin-dArc renamed to Chames 1825, Chames renamed to Vallon 25 September 1948, Vallon becomes Vallon-Pont-dArc The Pont dArc The Chauvet Cave is not open to the public. An exposition site, copied from the cave, is open to the public so they can discover the oldest paleolithic paintings -32.000 B. C. Every summer, many events are organized, the lavender feast, deceased in 1971 the painter René Aberlenc Communes of the Ardèche department INSEE

Limestone
–
Limestone is a sedimentary rock, composed mainly of skeletal fragments of marine organisms such as coral, forams and molluscs. Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate, about 10% of sedimentary rocks are limestones. The solubility of limestone in water and weak acid solutions leads to karst landscapes, most cave systems are through limestone bedrock. The first geologist to distinguish limestone from dolomite was Belsazar Hacquet in 1778, like most other sedimentary rocks, most limestone is composed of grains. Most grains in limestone are skeletal fragments of organisms such as coral or foraminifera. Other carbonate grains comprising limestones are ooids, peloids, intraclasts and these organisms secrete shells made of aragonite or calcite, and leave these shells behind when they die. Limestone often contains variable amounts of silica in the form of chert or siliceous skeletal fragment, some limestones do not consist of grains at all, and are formed completely by the chemical precipitation of calcite or aragonite, i. e. travertine. Secondary calcite may be deposited by supersaturated meteoric waters and this produces speleothems, such as stalagmites and stalactites. Another form taken by calcite is oolitic limestone, which can be recognized by its granular appearance, the primary source of the calcite in limestone is most commonly marine organisms. Some of these organisms can construct mounds of rock known as reefs, below about 3,000 meters, water pressure and temperature conditions cause the dissolution of calcite to increase nonlinearly, so limestone typically does not form in deeper waters. Limestones may also form in lacustrine and evaporite depositional environments, calcite can be dissolved or precipitated by groundwater, depending on several factors, including the water temperature, pH, and dissolved ion concentrations. Calcite exhibits a characteristic called retrograde solubility, in which it becomes less soluble in water as the temperature increases. Impurities will cause limestones to exhibit different colors, especially with weathered surfaces, Limestone may be crystalline, clastic, granular, or massive, depending on the method of formation. Crystals of calcite, quartz, dolomite or barite may line small cavities in the rock, when conditions are right for precipitation, calcite forms mineral coatings that cement the existing rock grains together, or it can fill fractures. Travertine is a banded, compact variety of limestone formed along streams, particularly there are waterfalls. Calcium carbonate is deposited where evaporation of the leaves a solution supersaturated with the chemical constituents of calcite. Tufa, a porous or cellular variety of travertine, is found near waterfalls, coquina is a poorly consolidated limestone composed of pieces of coral or shells. During regional metamorphism that occurs during the building process, limestone recrystallizes into marble

Prehistoric art
–
At this point ancient art begins, for the older literate cultures. The end-date for what is covered by the term thus varies greatly between different parts of the world, from the Upper Palaeolithic through the Mesolithic, cave paintings and portable art such as figurines and beads predominated, with decorative figured workings also seen on some utilitarian objects. In the Neolithic evidence of early pottery appeared, as did sculpture, Early rock art also first appeared in the Neolithic. It also saw the development in areas of artisans, a class of people specializing in the production of art. By the Iron Age, civilizations with writing had arisen from Ancient Egypt to Ancient China, some cultures, notably the Maya civilization, independently developed writing during the time they flourished, which was then later lost. These cultures may be classified as prehistoric, especially if their writing systems have not been deciphered, the earliest undisputed art originated with the Aurignacian archaeological culture in the Upper Paleolithic. However, there is evidence that the preference for the aesthetic emerged in the Middle Paleolithic. Some archaeologists have interpreted certain Middle Paleolithic artifacts as early examples of artistic expression, there are other claims of Middle Paleolithic sculpture, dubbed the Venus of Tan-Tan and the Venus of Berekhat Ram. In 2002 in Blombos cave, situated in South Africa, stones were discovered engraved with grid or cross-hatch patterns and this suggested to some researchers that early Homo sapiens were capable of abstraction and production of abstract art or symbolic art. Several archaeologists including Richard Klein are hesitant to accept the Blombos caves as the first example of actual art, the oldest undisputed works of figurative art were found in the Schwäbische Alb, Baden-Württemberg, Germany. The earliest of these, the Venus figurine known as the Venus of Hohle Fels, monumental open-air art in Europe from this period includes the rock-art at Côa Valley and Mazouco in Portugal, Domingo García and Siega Verde in Spain, and Rocher gravé de Fornols in France. A cave at Turobong in South Korea containing human remains has found to contain carved deer bones. Petroglyphs of deer or reindeer found at Sokchang-ri may also date to the Upper Paleolithic, potsherds in a style reminiscent of early Japanese work have been found at Kosan-ri on Jeju island, which, due to lower sea levels at the time, would have been accessible from Japan. The oldest petroglyphs are dated to approximately the Mesolithic and late Upper Paleolithic boundary, the earliest undisputed African rock art dates back about 10,000 years. The first naturalistic paintings of humans found in Africa date back about 8,000 years apparently originating in the Nile River valley, noted sites containing early art include Tassili nAjjer in southern Algeria, Tadrart Acacus in Libya, and the Tibesti Mountains in northern Chad. Rock carvings at the Wonderwerk Cave in South Africa have been dated to this age, contentious dates as far back as 29,000 years have been obtained at a site in Tanzania. A site at the Apollo 11 Cave complex in Namibia has been dated to 27,000 years, göbekli Tepe in Turkey has circles of massive T-shaped stone pillars dating back to the 10th–8th millennium BCE, the worlds oldest known megaliths. Many of the pillars are decorated with abstract, enigmatic pictograms, Asia was the cradle for several significant civilizations, most notably those of China and South Asia

UNESCO
–
The United Nations Educational, Scientific and Cultural Organization is a specialized agency of the United Nations based in Paris. It is the heir of the League of Nations International Committee on Intellectual Cooperation, UNESCO has 195 member states and nine associate members. Most of its offices are cluster offices covering three or more countries, national and regional offices also exist. UNESCO pursues its objectives through five major programs, education, natural sciences, social/human sciences, culture and it is also a member of the United Nations Development Group. UNESCO and its mandate for international cooperation can be traced back to a League of Nations resolution on 21 September 1921, on 18 December 1925, the International Bureau of Education began work as a non-governmental organization in the service of international educational development. However, the work of predecessor organizations was largely interrupted by the onset of World War II. On 30 October 1943, the necessity for an organization was expressed in the Moscow Declaration, agreed upon by China, the United Kingdom, the United States. This was followed by the Dumbarton Oaks Conference proposals of 9 October 1944, a prominent figure in the initiative for UNESCO was Rab Butler, the Minister of Education for the United Kingdom. At the ECO/CONF, the Constitution of UNESCO was introduced and signed by 37 countries, the Preparatory Commission operated between 16 November 1945, and 4 November 1946—the date when UNESCOs Constitution came into force with the deposit of the twentieth ratification by a member state. The first General Conference took place between 19 November to 10 December 1946, and elected Dr. Julian Huxley to Director-General and this change in governance distinguished UNESCO from its predecessor, the CICI, in how member states would work together in the organizations fields of competence. In 1956, the Republic of South Africa withdrew from UNESCO claiming that some of the organizations publications amounted to interference in the racial problems. South Africa rejoined the organization in 1994 under the leadership of Nelson Mandela, UNESCOs early work in the field of education included the pilot project on fundamental education in the Marbial Valley, Haiti, started in 1947. This project was followed by missions to other countries, including, for example. In 1948, UNESCO recommended that Member States should make free primary education compulsory, in 1990, the World Conference on Education for All, in Jomtien, Thailand, launched a global movement to provide basic education for all children, youths and adults. Ten years later, the 2000 World Education Forum held in Dakar, Senegal, UNESCOs early activities in culture included, for example, the Nubia Campaign, launched in 1960. The purpose of the campaign was to move the Great Temple of Abu Simbel to keep it from being swamped by the Nile after construction of the Aswan Dam, during the 20-year campaign,22 monuments and architectural complexes were relocated. This was the first and largest in a series of campaigns including Mohenjo-daro, Fes, Kathmandu, Borobudur, the organizations work on heritage led to the adoption, in 1972, of the Convention concerning the Protection of the World Cultural and Natural Heritage. The World Heritage Committee was established in 1976 and the first sites inscribed on the World Heritage List in 1978, since then important legal instruments on cultural heritage and diversity have been adopted by UNESCO member states in 2003 and 2005

Speleology
–
Speleology and caving are often connected, as the physical skills required for in situ study are the same. In Romania, the term speology is used, this is derived from a Greek word for cave, speos, rather than the Latin, spelaeum. Speleology is a field that combines the knowledge of chemistry, biology, geology, physics, meteorology and cartography to develop portraits of caves as complex. In 1895 Martel founded the Société de Spéléologie, the first organization devoted to science in the world. The creation of an accurate, detailed map is one of the most common technical activities undertaken within a cave, caves provide a home for many unique biota. Cave ecologies are diverse, and not sharply distinct from surface habitats. Generally however, the deeper the cave becomes, the more rarefied the ecology, cave environments fall into three general categories, Endogean the parts of caves that are in communication with surface soils through cracks and rock seams, groundwater seepage, and root protrusion. Parahypogean the threshold regions near cave mouths that extend to the last penetration of sunlight and these can be in regular contact with the surface via wind and underground rivers, or the migration of animals, or can be almost entirely isolated. Deep hypogean environments can host autonomous ecologies whose primary source of energy is not sunlight, cave organisms fall into three basic classes, There are also so-called accidental trogloxenes which are surface organisms that enter caves for no survival reason. Some may even be troglophobes, which survive in caves for any extended period. Examples include deer which fell through a sinkhole, frogs swept into a cave by a flash flood, the two factors that limit cave ecologies are generally energy and nutrients. To some degree moisture is available in actively forming Karst caves. Cut off from the sunlight and steady deposition of plant detritus, the majority of energy in cave environments comes from the surplus of the ecosystems outside. One major source of energy and nutrients in caves is dung from trogloxenes, because of their rarity and position in the ecosystem they are threatened by a large number of human activities. Dam construction, limestone quarrying, water pollution and logging are just some of the disasters that can devastate or destroy underground biological communities. Speleologists also work with archaeologists in studying underground ruins, tunnels, sewers and aqueducts, such as the various inlets and outlets of the Cloaca Maxima in Rome

Fossil
–
Fossils are the preserved remains or traces of animals, plants, and other organisms from the remote past. The totality of fossils, both discovered and undiscovered, and their placement in fossiliferous rock formations and sedimentary layers is known as the fossil record. The study of fossils across geological time, how they were formed, such a preserved specimen is called a fossil if it is older than some minimum age, most often the arbitrary date of 10,000 years. The observation that fossils were associated with certain rock strata led early geologists to recognize a geological timescale in the 19th century. The development of dating techniques in the early 20th century allowed geologists to determine the numerical or absolute age of the various strata. Like extant organisms, fossils vary in size from microscopic, even single bacterial cells one micrometer in diameter, to gigantic, such as dinosaurs, Fossils may also consist of the marks left behind by the organism while it was alive, such as animal tracks or feces. These types of fossil are called trace fossils, as opposed to body fossils, finally, past life leaves some markers that cannot be seen but can be detected in the form of biochemical signals, these are known as chemofossils or biosignatures. The process of fossilization varies according to type and external conditions. Permineralization is a process of fossilization that occurs when an organism is buried, the empty spaces within an organism become filled with mineral-rich groundwater. Minerals precipitate from the groundwater, occupying the empty spaces and this process can occur in very small spaces, such as within the cell wall of a plant cell. Small scale permineralization can produce very detailed fossils, for permineralization to occur, the organism must become covered by sediment soon after death or soon after the initial decay process. The degree to which the remains are decayed when covered determines the later details of the fossil, some fossils consist only of skeletal remains or teeth, other fossils contain traces of skin, feathers or even soft tissues. This is a form of diagenesis, in some cases the original remains of the organism completely dissolve or are otherwise destroyed. The remaining organism-shaped hole in the rock is called an external mold, if this hole is later filled with other minerals, it is a cast. An endocast or internal mold is formed when sediments or minerals fill the cavity of an organism. This is a form of cast and mold formation. If the chemistry is right, the organism can act as a nucleus for the precipitation of minerals such as siderite, if this happens rapidly before significant decay to the organic tissue, very fine three-dimensional morphological detail can be preserved. Nodules from the Carboniferous Mazon Creek fossil beds of Illinois, USA, are among the best documented examples of such mineralization, replacement occurs when the shell, bone or other tissue is replaced with another mineral

Archaeology
–
Archaeology, or archeology, is the study of human activity through the recovery and analysis of material culture. The archaeological record consists of artifacts, architecture, biofacts or ecofacts, Archaeology can be considered both a social science and a branch of the humanities. In North America, archaeology is considered a sub-field of anthropology, 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 as a field is distinct from the discipline of palaeontology, Archaeology is particularly important for learning about prehistoric societies, for whom there may be no written records to study. Prehistory includes over 99% of the human past, from the Paleolithic until the advent of literacy in societies across the world, Archaeology has various goals, which range from understanding culture history to reconstructing past lifeways to documenting and explaining changes in human societies through time. The discipline involves surveying, excavation and eventually analysis of data collected to learn more about the past, in broad scope, archaeology relies on cross-disciplinary research. Archaeology developed out of antiquarianism in Europe during the 19th century, Archaeology has been used by nation-states to create particular visions of the past. Nonetheless, today, archaeologists face many problems, such as dealing with pseudoarchaeology, the looting of artifacts, a lack of public interest, the science of archaeology grew out of the older multi-disciplinary study known as antiquarianism. Antiquarians studied history with attention to ancient artifacts and manuscripts. Tentative steps towards the systematization of archaeology as a science took place during the Enlightenment era in Europe in the 17th and 18th centuries, in Europe, philosophical interest in the remains of Greco-Roman civilization and the rediscovery of classical culture began in the late Middle Age. Antiquarians, including John Leland and William Camden, conducted surveys of the English countryside, one of the first sites to undergo archaeological excavation was Stonehenge and other megalithic monuments in England. John Aubrey was a pioneer archaeologist who recorded numerous megalithic and other monuments in southern England. He was also ahead of his time in the analysis of his findings and he attempted to chart the chronological stylistic evolution of handwriting, medieval architecture, costume, and shield-shapes. Excavations were also carried out in the ancient towns of Pompeii and Herculaneum and these excavations began in 1748 in Pompeii, while in Herculaneum they began in 1738. The discovery of entire towns, complete with utensils and even human shapes, however, prior to the development of modern techniques, excavations tended to be haphazard, the importance of concepts such as stratification and context were overlooked. The father of archaeological excavation was William Cunnington and he undertook excavations in Wiltshire from around 1798, funded by Sir Richard Colt Hoare. Cunnington made meticulous recordings of neolithic and Bronze Age barrows, one of the major achievements of 19th century archaeology was the development of stratigraphy. The idea of overlapping strata tracing back to successive periods was borrowed from the new geological and paleontological work of scholars like William Smith, James Hutton, the application of stratigraphy to archaeology first took place with the excavations of prehistorical and Bronze Age sites

Jean Clottes
–
Jean Clottes is a prominent French prehistorian. He was born in the French Pyrenees in 1933 and began to study archaeology in 1959 and he initially focused on Neolithic dolmens, which were the topic of his 1975 Ph. D. thesis at the University of Toulouse. After being appointed director of antiquities for the Midi-Pyrénées in 1971. In the following years he led a series of excavations of sites in the region. In 1992, he was named General Inspector for Archaeology at the French Ministry of Culture and he formally retired in 1999, but remains an active contributor to the field. To date he has written over 300 scientific papers, and has edited, co-edited, written and he has also lectured around the world, taught at the University of Toulouse and the University of California at Berkeley, and engaged in numerous public outreach and professional service activities. He has received honors from the French government and also from the Blue Tuareg people of the Sahara Desert. Radiocarbon dating showed that the paintings of Chauvet are approximately 30, 000-32,000 years old, in 1994 he joined with South African anthropologist David Lewis-Williams to study prehistoric art in light of known neuropsychological phenomena associated with shamanic trances. Together they concluded there is a strong argument for believing that much of prehistoric art was in fact produced in the context of shamanic practices. In 1996 they published their findings in the book Les Chamanes de la Préhistoire, the book received heavy criticism from some other researchers. However, other experts have found the ideas compelling, and suggested that academic infighting or jealousy may have played a role in the criticism, in response to their critics, Clottes and Lewis-Williams published an expanded version of their book in 2001. David Lewis-Williams later went on to develop aspects of their thesis more fully in his own book The Mind in the Cave and its sequel, Inside the Neolithic Mind

The Aurignacian culture is an archaeological culture of the Upper Palaeolithic. It is the earliest modern human culture in Europe, and is associated with the immigration of anatomically modern humans from the Near East and it first appeared in Eastern Europe around 43,000 BP, and in Western Europe between 40,000 and 36,000 years BP. It was replaced by the Gravettian culture around 28,000 to 26,000 years ago, the name originates from the type site of Aurignac, Haute-Garonne, which is a town in the south-west of France near Toulouse or Andorra. The oldest undisputed example of figurative art, the Venus of Hohle Fels. It was discovered in September 2008 in a cave at Schelklingen in Baden-Württemberg in southern Germany, the Bacho Kiro site is one of the earliest known Aurignacian burials. The Aurignacian tool industry is characterized by worked bone or antler points with grooves cut in the bottom. Their flint tools include blades and bladelets struck from prepared cores rather than using crude flakes. )The people of this culture also produced some of the earliest known cave art, such as the animal engravings at Trois Freres. They also made pendants, bracelets, and ivory beads, as well as three-dimensional figurines, perforated rods, thought to be spear throwers or shaft wrenches, also are found at their sites. The sophistication and self-awareness demonstrated in the work led archaeologists to consider the makers of Aurignacian artifacts the first modern humans in Europe, human remains and Late Aurignacian artifacts found in juxtaposition support this inference. Although finds of human remains in direct association with Proto-Aurignacian technologies are scarce in Europe. At least three robust, but typically anatomically-modern individuals from the Peștera cu Oase cave in Romania, were dated directly from the bones to ca, although not associated directly with archaeological material, these finds are within the chronological and geographical range of the Early Aurignacian in southeastern Europe. On genetic evidence it has argued that both Aurignacian and the Dabba culture of North Africa came from an earlier big game hunting Aurignacian culture of the Levant. Many 35, 000-year-old animal figurines were discovered in the Vogelherd Cave in Germany, one of the horses, amongst six tiny mammoth and horse ivory figures found previously at Vogelherd, was sculpted as skillfully as any piece found throughout the Upper Paleolithic. The production of ivory beads for body ornamentation was also important during the Aurignacian, there is a notable absence of painted caves, however, which begin to appear within the Solutrean. Typical statuettes consist of women that are called Venus figurines and they emphasize the hips, breasts, and other body parts associated with fertility. Feet and arms are lacking or minimized, one of the most ancient figurines was discovered in 2008 in the Hohle Fels cave in Germany. The figurine has been dated to 35,000 years ago, the oldest undisputed musical instrument was the Hohle Fels Flute discovered in the Hohle Fels cave in Germanys Swabian Alb in 2008. The flute is made from a wing bone perforated with five finger holes

Pont d'Arc
–
The Pont dArc is a large natural bridge, located in the Ardèche département in the south of France,5 km from the town of Vallon-Pont-dArc. The arch, carved out by the Ardèche River, is 60 m wide and 54 m high and it is a very popular canoeing and kayaking area and is heavily visited by tourists. It is usually described as the entrance to the Ardèche Canyon. In the near vicinity of the arch is the Chauvet-Pont-dArc Cave, containing the earliest known cave paintings

Geology
–
Geology is an earth science concerned with the solid Earth, the rocks of which it is composed, and the processes by which they change over time. Geology can also refer generally to the study of the features of any terrestrial planet. Geology gives insight into the history of the Earth by providing the evidence for plate tectonics, the evolutionary history of life. Geology also plays a role in engineering and is a major academic discipline. The majority of data comes from research on solid Earth materials. These typically fall into one of two categories, rock and unconsolidated material, the majority of research in geology is associated with the study of rock, as rock provides the primary record of the majority of the geologic history of the Earth. There are three types of rock, igneous, sedimentary, and metamorphic. The rock cycle is an important concept in geology which illustrates the relationships between three types of rock, and magma. When a rock crystallizes from melt, it is an igneous rock, the sedimentary rock can then be subsequently turned into a metamorphic rock due to heat and pressure and is then weathered, eroded, deposited, and lithified, ultimately becoming a sedimentary rock. Sedimentary rock may also be re-eroded and redeposited, and metamorphic rock may also undergo additional metamorphism, all three types of rocks may be re-melted, when this happens, a new magma is formed, from which an igneous rock may once again crystallize. Geologists also study unlithified material which typically comes from more recent deposits and these materials are superficial deposits which lie above the bedrock. Because of this, the study of material is often known as Quaternary geology. This includes the study of sediment and soils, including studies in geomorphology, sedimentology and this theory is supported by several types of observations, including seafloor spreading, and the global distribution of mountain terrain and seismicity. This coupling between rigid plates moving on the surface of the Earth and the mantle is called plate tectonics. The development of plate tectonics provided a basis for many observations of the solid Earth. Long linear regions of geologic features could be explained as plate boundaries, mid-ocean ridges, high regions on the seafloor where hydrothermal vents and volcanoes exist, were explained as divergent boundaries, where two plates move apart. Arcs of volcanoes and earthquakes were explained as convergent boundaries, where one plate subducts under another, transform boundaries, such as the San Andreas Fault system, resulted in widespread powerful earthquakes. Plate tectonics also provided a mechanism for Alfred Wegeners theory of continental drift and they also provided a driving force for crustal deformation, and a new setting for the observations of structural geology

Radiocarbon dating
–
Radiocarbon dating is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. The method was developed by Willard Libby in the late 1940s, Libby received the Nobel Prize for his work in 1960. The radiocarbon dating method is based on the fact that radiocarbon is constantly being created in the atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting radiocarbon combines with oxygen to form radioactive carbon dioxide. When the animal or plant dies, it stops exchanging carbon with its environment, and from that point onwards the amount of 14C it contains begins to decrease as the 14C undergoes radioactive decay. Measuring the amount of 14C in a sample from a plant or animal such as a piece of wood or a fragment of bone provides information that can be used to calculate when the animal or plant died. The idea behind radiocarbon dating is straightforward, but years of work were required to develop the technique to the point where accurate dates could be obtained. Research has been ongoing since the 1960s to determine what the proportion of 14C in the atmosphere has been over the past fifty thousand years. The resulting data, in the form of a curve, is now used to convert a given measurement of radiocarbon in a sample into an estimate of the samples calendar age. Other corrections must be made to account for the proportion of 14C in different types of organisms, additional complications come from the burning of fossil fuels such as coal and oil, and from the above-ground nuclear tests done in the 1950s and 1960s. Conversely, nuclear testing increased the amount of 14C in the atmosphere, measurement of radiocarbon was originally done by beta-counting devices, which counted the amount of beta radiation emitted by decaying 14C atoms in a sample. The development of dating has had a profound impact on archaeology. In addition to permitting more accurate dating within archaeological sites than previous methods, histories of archaeology often refer to its impact as the radiocarbon revolution. Radiocarbon dating has allowed key transitions in prehistory to be dated, such as the end of the last ice age, and they synthesized 14C using the laboratorys cyclotron accelerator and soon discovered that the atoms half-life was far longer than had been previously thought. This was followed by a prediction by Serge A. Korff, then employed at the Franklin Institute in Philadelphia and it had previously been thought that 14C would be more likely to be created by deuterons interacting with 13C. At some time during World War II, Willard Libby, who was then at Berkeley, learned of Korffs research, in 1945, Libby moved to the University of Chicago where he began his work on radiocarbon dating. He published a paper in 1946 in which he proposed that the carbon in living matter might include 14C as well as non-radioactive carbon, by contrast, methane created from petroleum showed no radiocarbon activity because of its age. The results were summarized in a paper in Science in 1947, Libby and James Arnold proceeded to test the radiocarbon dating theory by analyzing samples with known ages

Gravettian
–
The Gravettian was an archaeological industry of the European Upper Paleolithic that succeeded the Aurignacian c.31,000 BC. It is archaeologically the last unified European culture, and lasted until c.22,000 BC, at this point it developed into the Epigravettian in Italy, the Balkans, and Russia, and was replaced abruptly by the Solutrean in France and Spain. The origins of the Gravettian people are not clear, they seem to appear all over Europe. Like their Aurignacian predecessors, they are well-known for their Venus figurines, the culture was first identified at the site of La Gravette in Southwestern France. One typical artefact of the industry, once considered diagnostic, is a pointed blade with a straight blunt back. These were used to hunt big game including bison, horse, reindeer, Gravettians also used nets to hunt small game. Archaeologists usually describe two regional variants, the western Gravettian, known namely from cave sites in France, Spain and Britain, and the eastern Gravettian in Central Europe and Russia. The eastern Gravettians — they include the Pavlovian culture — were specialized mammoth hunters, whose remains are found not in caves. The Aurignacian and Gravettian cultures are featured in Earths children, a series of set in prehistory. In this piece of fiction, the Venus figurines play an important role at the center of a fertility rite

Hearths
–
In historic and modern usage, a hearth /ˈhɑːrθ/ is a brick- or stone-lined fireplace, with or without an oven, used for heating and originally also used for cooking food. In a medieval hall, the hearth commonly stood in the middle of the hall, later, such hearths were moved to the side of the room and provided with a chimney. In fireplace design, the hearth is the part of the fireplace where the fire burns, usually consisting of masonry at floor level or higher, the word hearth derives from an Indo-European root, *ker-, referring to burning, heat, and fire. In archaeology, a hearth is a firepit or other feature of any period. Hearths are common features of many eras going back to prehistoric campsites and they were used for cooking, heating, and the processing of some stone, wood, faunal, and floral resources. Farming or excavation—deform or disperse hearth features, making difficult to identify without careful study. Lined hearths are easily identified by the presence of fire-cracked rock, often present are fragmented fish and animal bones, carbonized shell, charcoal, ash, and other waste products, all embedded in a sequence of soil that has been deposited atop the hearth. Unlined hearths, which are easily identified, may also include these materials. Because of the nature of most of these items, they can be used to pinpoint the date the hearth was last used via the process of radiocarbon dating. Although carbon dates can be affected if the users of the hearth burned old wood or coal. This was the most common way to cook, and to interior spaces in cool seasons. Kapnikon was a tax raised on households without exceptions for the poor, in England, a tax on hearths was introduced on 19 May 1662. Householders were required to pay a charge of two shillings per annum for each hearth, with half the payment due at Michaelmas and half at Lady Day. Exemptions to the tax were granted, to those in receipt of relief, those whose houses were worth less than 20 shillings a year. Also exempt were charitable institutions such as schools and almshouses, and industrial hearths with the exception of smiths forges, the returns were lodged with the Clerk of the Peace between 1662 and 1688. A revision of the Act in 1664 made the tax payable by all who had more than two chimneys The tax was abolished by William III in 1689 and the last collection was for Lady Day of that year and it was abolished in Scotland in 1690. Hearth tax records are important to historians as they provide an indication of the size of each assessed house at the time. The numbers of hearths are generally proportional to the size of the house, the assessments can be used to indicate the numbers and local distribution of larger and smaller houses

Cave bear
–
The cave bear was a species of bear that lived in Europe and Asia during the Pleistocene and became extinct about 24,000 years ago during the Last Glacial Maximum. Both the word cave and the scientific name spelaeus are used because fossils of species were mostly found in caves. This reflects the views of experts that cave bears may have spent more time in caves than the brown bear, Cave bear skeletons were first described in 1774 by Johann Friederich Esper in his book Newly Discovered Zoolites of Unknown Four Footed Animals. While scientists at the time considered that the skeletons could belong to apes, canids, felids, or even dragons or unicorns, twenty years later, Johann Christian Rosenmüller, an anatomist at the Leipzig University, gave the species its binomial name. The bones were so numerous that most researchers had little regard for them, during World War I, with the scarcity of phosphate dung, earth from the caves where cave bear bones occurred were used as a source of phosphates. When the dragon caves in Austrias Steiermark region were exploited for this purpose, only the skulls, many caves in Central Europe have skeletons of cave bears inside, for example the Heinrichshöhle in Hemer, the Dechenhöhle in Iserlohn, Germany. A complete skeleton, five complete skulls, and 18 other boness were found inside Jaskinia Niedźwiedzia in 1966 in Poland, in Romania, in a cave called Bears Cave,140 cave bear skeletons were discovered in 1983. Both the cave bear and the bear are thought to be descended from the Plio-Pleistocene Etruscan bear that lived about 5.3 Mya to 10,000 years ago. The last common ancestor of cave bears and brown bears lived between 1.2 and 1.4 Mya. The immediate precursor of the bear was probably Ursus deningeri. Ursus spelaeus deningeroides, while other authorities consider both taxa to be variants of the same species. Cave bears found in different regions vary in age, thus facilitating investigations into evolutionary trends, the three anterior premolars were gradually reduced, then disappeared, possibly in response to a largely vegetarian diet. In a fourth of the found in the Conturines, the third premolar is still present. The last remaining premolar became conjugated with the molars, enlarging the crown and granting it more cusps. This phenomenon, known as molarization, improved the mastication capacities of the molars and this allowed the cave bear to gain more energy for hibernation, while eating less than its ancestors. The cave bear had a broad, domed skull with a steep forehead. Its stout body had long thighs, massive shins and in-turning feet, Cave bears were comparable in size to the largest modern-day bears. The average weight for males was 400 to 500 kilograms, with a specimen weighing 817 kg or more

Skull
–
The skull is a bony structure that forms the head of the skeleton in most vertebrates. It supports the structures of the face and provides a cavity for the brain. The skull is composed of two parts, the cranium and the mandible, in the human these two parts are the neurocranium and the viscerocranium or facial skeleton that includes the mandible as its largest bone. The skull forms the anterior most portion of the skeleton and is a product of cephalisation—housing the brain, and several sensory structures such as the eyes, ears, nose, in the human these sensory structures are part of the facial skeleton. In some animals such as horned ungulates, the skull also has a function by providing the mount for the horns. The English word skull is probably derived from Old Norse skulle, while the Latin word cranium comes from the Greek root κρανίον, the skull is made up of a number of fused flat bones, and contains many foramina and processes, and several cavities or sinuses. For details and the constituent bones, see neurocranium and viscerocranium, the human skull is the bony structure that forms the head in the human skeleton. It supports the structures of the face and forms a cavity for the brain, like the skulls of other vertebrates, it protects the brain from injury. The skull consists of two parts, of different embryological origin—the neurocranium and the facial skeleton, the neurocranium forms the protective cranial cavity that surrounds and houses the brain and brainstem. The facial skeleton is formed by the supporting the face. Except for the mandible, all of the bones of the skull are joined together by sutures—synarthrodial joints formed by bony ossification, sometimes there can be extra bone pieces within the suture known as wormian bones or sutural bones. The human skull is considered to consist of twenty-two bones—eight cranial bones. In the neurocranium these are the bone, two temporal bones, two parietal bones, the sphenoid, ethmoid and frontal bones. The bones of the skeleton are the vomer, two nasal conchae, two nasal bones, two maxilla, the mandible, two palatine bones, two zygomatic bones, and two lacrimal bones. Some of these bones—the occipital, parietal, frontal, in the neurocranium, and the nasal, lacrimal, the skull also contains sinus cavities and numerous foramina. The sinuses are lined with respiratory epithelium and their known functions are the lessening of the weight of the skull, the aiding of resonance to the voice and the warming and moistening of the air drawn through the nasal cavity. The foramina are openings in the skull, the largest of these is the foramen magnum that allows the passage of the spinal cord as well as nerves and blood vessels. The many processes of the include the mastoid process and the zygomatic process

Capra (genus)
–
Capra is a genus of mammals, the goats or wild goats, composed of up to nine species, including the wild goat, the markhor, and several species known as ibex. The domestic goat is a subspecies of the wild goat. Evidence of goat domestication dates back more than 8,500 years, wild goats are animals of mountain habitats. They are very agile and hardy, able to climb on bare rock, the Rocky Mountain goat is in a separate genus, Oreamnos. All members of the Capra genus are bovids, and more specifically caprids, as such they are ruminants, meaning they chew the cud, and have four-chambered stomachs which play a vital role in digesting, regurgitating, and redigesting their food. The genus has sometimes taken to include Ovis and Ammotragus. In this smaller genus, some authors have recognized two species, the markhor on one side and all other forms included in one species on the other side. Recent studies based on mitochondrial DNA suggest that the Siberian ibex and the Nubian ibex represent distinct species, the Alpine ibex forms a group with the Spanish ibex. The West Caucasian tur appears to be closely related to the wild goat than to the East Caucasian tur. The markhor is relatively separated from other forms—previously it had been considered to be a separate branch of the genus. Almost all wild species are allopatric —the only geographical overlaps are the wild goat with the East Caucasian tur. In both cases, the species do not usually interbreed in the wild, but in captivity, all Capra species can interbreed. Along with sheep, goats were among the first domesticated animals, the domestication process started at least 10,000 years ago in what is now northern Iran. Easy human access to hair, meat, and milk were the primary motivations. Goat skins were used until the Middle Ages for water and wine bottles when traveling and camping. Evidence of the ibex is widely present in the record, particularly in the Near East. Ibex motifs are common on cylinder seals and pottery, both painted and embossed. Excavations from Minoan Crete at Knossos, for example, have yielded specimens from about 1800 BC, from the similar age a gold jewelry ibex image was found at the Akrotiri archaeological site on Santorini in present-day Greece

Origin of the domestic dog
–
The origin of the domestic dog is not clear. The domestic dog is a member of genus Canis that forms part of the wolf-like canids, the closest living relative of the dog is the gray wolf and there is no evidence of any other canine contributing to its genetic lineage. The dog and the extant gray wolf form two clades, with modern wolves not closely related to the wolves that were first domesticated. The archaeological record shows the first undisputed dog remains buried beside humans 14,700 years ago and these dates imply that the earliest dogs arose in the time of human hunter-gatherers and not agriculturists. The dog was the first domesticated species, where the genetic divergence of dog and wolf took place remains controversial, with the most plausible proposals spanning Western Europe, Central Asia, and East Asia. The Western Eurasian dog population was partially and gradually replaced by East Asian dogs introduced by humans at least 6,400 years ago. Six million years ago at the close of the Miocene era, the climate was gradually cooling and this would lead to the glaciations of the Pliocene. In many areas the forests and savannahs were being replaced with steppe or grasslands, on opposite sides of the planet, two very different lineages would adapt to these changes and their evolution would produce two species that would become the most widely distributed of mammals. In eastern Africa, a split was occurring among the large primates, the two lineages would ultimately meet on the Eurasian continent. Further Information, Canid evolution Dog evolution is the descent with modification that led to the domestic dog. This process encompasses small-scale evolution and large-scale evolution, the domestic dog is the most widely abundant large carnivore. When and where dogs were first domesticated has vexed geneticists for the past 20 years, the range of natural variation among these characters that may have existed in ancient wolf populations, and the time it took for these traits to appear in dogs, are unknown. However, recent studies based on genetics propose four generalizations about dogs, over the past million years, numerous wolf-like forms existed but their turnover has been high, and modern wolves are not the lineal ancestors of dogs. This indicates that an extant wolf population that is the ancestor to dogs has not been found and is presumed extinct, the dog is not a separate species to the wolf. The dog was the first domesticated species and appeared more than 15,000 years before present, studies support two population bottlenecks had occurred to the dog lineage, one due to the initial domestication and one due to the formation of dog breeds. Dogs show both ancient and modern lineages, the ancient lineages appear most in Asia but least in Europe because the Victorian era development of modern dog breeds used little of the ancient lineages. All dog populations show some evidence of admixture between modern and ancient dogs. Some ancient dog populations that once occupied Europe and the New World no longer exist and this implies that some ancient dog populations were entirely replaced and others admixed over a long period of time

Steppe bison
–
It is believed to have evolved somewhere in South Asia, which would have it appearing at roughly the same time and region as the aurochs with which its descendants are sometimes confused. European cave paintings appear to depict both B. bonasus and B. priscus, the steppe bison was over 2 m tall at the shoulder, and resembled the modern bison species, reaching 900 kg in weight. The tips of the horns were a meter apart, the horns themselves being over half a meter long. Steppe bison appear in art, notably in the Cave of Altamira and Lascaux, and the carving Bison Licking Insect Bite. Blue Babe is the mummy of a 36, 000-year-old male steppe bison which was discovered north of Fairbanks, Alaska, in July 1979. The mummy was noticed by a miner who named the mummy Blue Babe - Babe for Paul Bunyans mythical giant ox. In 2011, a 9, 300-year-old mummy was found at Yukagir in Siberia, specimen found in Japan were named as Hanaizumimori cattle Leptobison hanaizumiensis, and bisons possibly herded with aurochs

Postage stamp
–
Postage stamp may also refer to a formatting artifact in the display of film or video, Windowbox. A postage stamp is a piece of paper that is purchased and displayed on an item of mail as evidence of payment of postage. Typically, stamps are printed on special paper, show a national designation and a denomination on the front. They are sometimes a source of net profit to the issuing agency, stamps are usually rectangular, but triangles or other shapes are occasionally used. The stamp is affixed to an envelope or other postal cover the customer wishes to send, the item is then processed by the postal system, where a postmark, sometimes known as a cancellation mark, is usually applied in overlapping manner to stamp and cover. This procedure marks the stamp as used to prevent its reuse, in modern usage, postmarks generally indicate the date and point of origin of the mailing. The mailed item is delivered to the address the customer has applied to the envelope or parcel. Postage stamps have facilitated the delivery of mail since the 1840s, before then, ink and hand-stamps, usually made from wood or cork, were often used to frank the mail and confirm the payment of postage. The first adhesive postage stamp, commonly referred to as the Penny Black, was issued in the United Kingdom in 1840, there are varying accounts of the inventor or inventors of the stamp. The postage stamp resolved this issue in a simple and elegant manner, concurrently with the first stamps, the UK offered wrappers for mail. S. Postal service for priority or express mailing, the postage stamp afforded convenience for both the mailer and postal officials, more effectively recovered costs for the postal service, and ultimately resulted in a better, faster postal system. With the conveniences stamps offered, their use resulted in greatly increased mailings during the 19th and 20th centuries, as postage stamps with their engraved imagery began to appear on a widespread basis, historians and collectors began to take notice. The study of stamps and their use is referred to as philately. Stamp collecting can be both a hobby and a form of study and reference, as government-issued postage stamps. The postage for the item was prepaid by the use of a hand-stamp to frank the mailed item. Though this stamp was applied to a letter instead of a piece of paper it is considered by many historians as the worlds first postage stamp. Rowland Hill The Englishman Sir Rowland Hill began interest in postal reform in 1835, in 1836, a Member of Parliament, Robert Wallace, provided Hill with numerous books and documents, which Hill described as a half hundred weight of material. Hill commenced a study of these documents, leading him to the 1837 publication of a pamphlet entitled Post Office Reform its Importance

Romania
–
Romania is a sovereign state located in Southeastern Europe. It borders the Black Sea, Bulgaria, Ukraine, Hungary, Serbia and it has an area of 238,391 square kilometres and a temperate-continental climate. With over 19 million inhabitants, the country is the member state of the European Union. Its capital and largest city, Bucharest, is the sixth-largest city in the EU, the River Danube, Europes second-longest river, rises in Germany and flows in a general southeast direction for 2,857 km, coursing through ten countries before emptying into Romanias Danube Delta. The Carpathian Mountains, which cross Romania from the north to the southwest are marked by one of their tallest peaks, Moldoveanu, modern Romania was formed in 1859 through a personal union of the Danubian Principalities of Moldavia and Wallachia. The new state, officially named Romania since 1866, gained independence from the Ottoman Empire in 1877, at the end of World War I, Transylvania, Bukovina and Bessarabia united with the sovereign Kingdom of Romania. Romania lost several territories, of which Northern Transylvania was regained after the war, following the war, Romania became a socialist republic and member of the Warsaw Pact. After the 1989 Revolution, Romania began a transition back towards democracy and it has been a member of NATO since 2004, and part of the European Union since 2007. A strong majority of the population identify themselves as Eastern Orthodox Christians and are speakers of Romanian. The cultural history of Romania is often referred to when dealing with artists, musicians, inventors. For similar reasons, Romania has been the subject of notable tourist attractions, Romania derives from the Latin romanus, meaning citizen of Rome. The first known use of the appellation was attested in the 16th century by Italian humanists travelling in Transylvania, Moldavia, after the abolition of serfdom in 1746, the word rumân gradually fell out of use and the spelling stabilised to the form român. Tudor Vladimirescu, a leader of the early 19th century. The use of the name Romania to refer to the homeland of all Romanians—its modern-day meaning—was first documented in the early 19th century. The name has been officially in use since 11 December 1861, in English, the name of the country was formerly spelt Rumania or Roumania. Romania became the predominant spelling around 1975, Romania is also the official English-language spelling used by the Romanian government. The Neolithic-Age Cucuteni area in northeastern Romania was the region of the earliest European civilization. Evidence from this and other sites indicates that the Cucuteni-Trypillian culture extracted salt from salt-laden spring water through the process of briquetage

Species
–
In biology, a species is the basic unit of biological classification and a taxonomic rank. A species is defined as the largest group of organisms in which two individuals can produce fertile offspring, typically by sexual reproduction. While this definition is often adequate, looked at more closely it is problematic, for example, with hybridisation, in a species complex of hundreds of similar microspecies, or in a ring species, the boundaries between closely related species become unclear. Other ways of defining species include similarity of DNA, morphology, all species are given a two-part name, a binomial. The first part of a binomial is the genus to which the species belongs, the second part is called the specific name or the specific epithet. For example, Boa constrictor is one of four species of the Boa genus, Species were seen from the time of Aristotle until the 18th century as fixed kinds that could be arranged in a hierarchy, the great chain of being. In the 19th century, biologists grasped that species could evolve given sufficient time, Charles Darwins 1859 book The Origin of Species explained how species could arise by natural selection. Genes can sometimes be exchanged between species by horizontal transfer, and species may become extinct for a variety of reasons. In his biology, Aristotle used the term γένος to mean a kind, such as a bird or fish, a kind was distinguished by its attributes, for instance, a bird has feathers, a beak, wings, a hard-shelled egg, and warm blood. A form was distinguished by being shared by all its members, Aristotle believed all kinds and forms to be distinct and unchanging. His approach remained influential until the Renaissance, when observers in the Early Modern period began to develop systems of organization for living things, they placed each kind of animal or plant into a context. Many of these early delineation schemes would now be considered whimsical, animals likewise that differ specifically preserve their distinct species permanently, one species never springs from the seed of another nor vice versa. In the 18th century, the Swedish scientist Carl Linnaeus classified organisms according to shared physical characteristics and he established the idea of a taxonomic hierarchy of classification based upon observable characteristics and intended to reflect natural relationships. At the time, however, it was widely believed that there was no organic connection between species, no matter how similar they appeared. However, whether or not it was supposed to be fixed, by the 19th century, naturalists understood that species could change form over time, and that the history of the planet provided enough time for major changes. Jean-Baptiste Lamarck, in his 1809 Zoological Philosophy, described the transmutation of species, proposing that a species could change over time, in 1859, Charles Darwin and Alfred Russel Wallace provided a compelling account of evolution and the formation of new species. Darwin argued that it was populations that evolved, not individuals and this required a new definition of species. Darwin concluded that species are what appear to be, ideas

Ice age
–
An ice age is a period of long-term reduction in the temperature of Earths surface and atmosphere, resulting in the presence or expansion of continental and polar ice sheets and alpine glaciers. Within a long-term ice age, individual pulses of cold climate are termed glacial periods, in the terminology of glaciology, ice age implies the presence of extensive ice sheets in both northern and southern hemispheres. In 1742 Pierre Martel, an engineer and geographer living in Geneva, two years later he published an account of his journey. He reported that the inhabitants of that valley attributed the dispersal of erratic boulders to the glaciers, later similar explanations were reported from other regions of the Alps. In 1815 the carpenter and chamois hunter Jean-Pierre Perraudin explained erratic boulders in the Val de Bagnes in the Swiss canton of Valais as being due to glaciers previously extending further. An unknown woodcutter from Meiringen in the Bernese Oberland advocated a similar idea in a discussion with the Swiss-German geologist Jean de Charpentier in 1834, comparable explanations are also known from the Val de Ferret in the Valais and the Seeland in western Switzerland and in Goethes scientific work. Such explanations could also be found in parts of the world. When the Bavarian naturalist Ernst von Bibra visited the Chilean Andes in 1849–1850, meanwhile, European scholars had begun to wonder what had caused the dispersal of erratic material. From the middle of the 18th century, some discussed ice as a means of transport, the Swedish mining expert Daniel Tilas was, in 1742, the first person to suggest drifting sea ice in order to explain the presence of erratic boulders in the Scandinavian and Baltic regions. In 1795, the Scottish philosopher and gentleman naturalist, James Hutton, two decades later, in 1818, the Swedish botanist Göran Wahlenberg published his theory of a glaciation of the Scandinavian peninsula. He regarded glaciation as a regional phenomenon, only a few years later, the Danish-Norwegian geologist Jens Esmark argued a sequence of worldwide ice ages. In a paper published in 1824, Esmark proposed changes in climate as the cause of those glaciations and he attempted to show that they originated from changes in Earths orbit. During the following years, Esmarks ideas were discussed and taken over in parts by Swedish, Scottish, at the University of Edinburgh Robert Jameson seemed to be relatively open to Esmarks ideas, as reviewed by Norwegian professor of glaciology Bjørn G. Andersen. Jamesons remarks about ancient glaciers in Scotland were most probably prompted by Esmark, in Germany, Albrecht Reinhard Bernhardi, a geologist and professor of forestry at an academy in Dreissigacker, since incorporated in the southern Thuringian city of Meiningen, adopted Esmarks theory. In a paper published in 1832, Bernhardi speculated about former polar ice caps reaching as far as the zones of the globe. When he read his paper before the Schweizerische Naturforschende Gesellschaft, most scientists remained sceptical, finally, Venetz convinced his friend Jean de Charpentier. De Charpentier transformed Venetzs idea into a theory with a limited to the Alps. In fact, both men shared the same volcanistic, or in de Charpentiers case rather plutonistic assumptions, about the Earths history, in 1834, de Charpentier presented his paper before the Schweizerische Naturforschende Gesellschaft

Predation
–
In an ecosystem, predation is a biological interaction where a predator feeds on its prey. Predators may or may not kill their prey prior to feeding on it, but the act of predation often results in the death of the prey, thus predation is often, though not always, carnivory. Other categories of consumption are herbivory, fungivory, and detritivory, all of these are consumer-resource systems. It can often be difficult to separate various types of feeding behaviors. For example, some parasites prey on their host and then lay their eggs on it, for their offspring to feed on it while it continues to live, the key characteristic of predation is the predators direct impact on the prey population. Selective pressures imposed on one another leads to an evolutionary arms race between prey and predator, resulting in various antipredator adaptations. Ways of classifying predation include grouping by trophic level or diet, by specialization, Predators can be classified by their interactions with their prey. Two factors are considered here, how close the predator and prey are, and whether the prey is killed by the predator. A true predator is one that kills and eats another living thing, Predators may hunt actively for prey in pursuit predation, or sit and wait for prey to approach within striking distance, as in ambush predators. Some predation entails venom that subdues a prey before the predator ingests it, as in the box jellyfish, or disables it, in some cases, the venom contributes to the digestion of the prey, as in rattlesnakes and some spiders. In contrast, baleen whales eat millions of microscopic plankton at once, seed and egg predation are true predation, as seeds and eggs are potential organisms. Predators need not eat prey entirely, for example, some predators cannot digest bones, some may eat only part of an organism, but still consistently cause its death. Grazing organisms do not often kill their prey, while some herbivores like zooplankton live on unicellular phytoplankton and therefore, by the individualized nature of the organism, kill their prey, many others only eat a small part of the plant. Grazing livestock may pull some grass out at the roots, but most is simply grazed upon, kelp is frequently grazed in subtidal kelp forests, but regrows at the base of the blade continuously to cope with browsing pressure. Animals may also be grazed upon, female mosquitos land on hosts briefly to gain sufficient proteins for the development of their offspring, starfish may be grazed on, being capable of regenerating lost arms. Parasites can at times be difficult to distinguish from grazers and their feeding behavior is similar in many ways, however they are noted for their close association with their host species. This close living arrangement may be described by the symbiosis, living together. Parasitic organisms range from the mistletoe, a parasitic plant

Panthera leo spelaea
–
Panthera leo spelaea or P. spelaea, commonly known as the European or Eurasian cave lion, is an extinct subspecies of lion. It is known from fossils and many examples of prehistoric art, P. leo spelaea has been proposed as a separate species Panthera spelaea. One authority considered the cave lion to be closely related to the tiger based on a comparison of skull shapes. Therefore, the cave lion ranged from Europe to Alaska over the Bering land bridge until the late Pleistocene, a recent DNA study indicates that it is a separate species which diverged from a common ancestor shared with the lion 1. It differed from Panthera leo spelaea by its size and from the American lion by its smaller size. In October 2015 two frozen cave lion cubs, estimated to be at least 10,000 years old, were discovered in Yakutia, Siberia in permafrost. Research on the specimens, named Uyan and Dina, indicated the cubs were likely barely a week old at the time of their deaths, further evidence shows the cubs were, like modern lions, hidden at a den site until they were old enough to join the pride. Researchers think that the cubs were trapped and killed by a landslide, and that without air, a second expedition to the site where the cubs were found is planned for 2016, in hopes of finding either the remains of a third cub or possibly the cubs mother. P. leo spelaea evolved from the earlier Panthera leo fossilis, genetic evidence indicates this lineage was isolated from extant lions after its dispersal to Europe. P. l. spelaea lived from 370,000 to 10,000 years ago, apparently, it became extinct about 12,400 14C years ago, as the Würm glaciation receded. The following cladogram shows the relationship between P. spelaea and other pantherines according to Barnett et al. besides Linnaeus, This subspecies was one of the largest lions. The skeleton of a male, which was found in 1985 near Siegsdorf, had a shoulder height of around 1.2 m. This is similar to the size of a large modern lion. A large specimen is estimated to weigh 317-362 kg, the size of this male has been exceeded by other specimens of this subspecies. Therefore, this cat may have been over 10% bigger than modern lions, the cave lion is known from Paleolithic cave paintings, ivory carvings, and clay figurines. Other archaeological artifacts indicate they were featured in Paleolithic religious rituals, in 2008, a well-preserved cave lion specimen was unearthed near the Maly Anyuy River in Chukotka, Russia, which still retained some clumps of hair. Some paintings of them in caves show several hunting together, which suggests the hunting strategy of contemporary lionesses, isotopic analyses of bone collagen samples extracted from fossils suggest reindeer and cave bear cubs were prominent in the diets of northwestern European cave lions. There was a suggestion of a shift in dietary preferences subsequent to the disappearance of the cave hyena, the last cave lions seem to have focused on reindeer, up to the brink of local extinction or extirpation of both species

Cave hyena
–
The cave hyena, also known as the Ice Age spotted hyena, was a paleosubspecies of spotted hyena which ranged from the Iberian Peninsula to eastern Siberia. It is one of the best known mammals of the Ice Age and is represented in many European bone caves. The cave hyena was a specialised animal, with its progressive and regressive features being more developed than in its modern African relative. The cause of the cave hyenas extinction is not fully understood, though it could have been due to a combination of factors, including climate change, the European cave hyena was much larger than its modern African cousin, having been estimated to weigh 190 kg. As with the African subspecies, female cave hyenas were larger than their male counterparts, paleolithic rock art depicting the cave hyena shows that it retained the spotted pelt of its African relative. Several den sites found in Europe indicate that the cave hyena preferentially targeted large prey, with wild horses predominating, followed by steppe bison, the cave hyenas favouring of horses is consistent with the behaviour of the modern African spotted hyena, which mostly hunts zebras. Secondary prey species included reindeer, red deer, giant deer, European ass, chamois, a small number of wolf remains have also been discovered in hyena den sites. The cave hyena likely killed wolves due to competition, though their presence in the cave site indicates that they were also fed upon. Similarly, cave lion and bear remains have been discovered in hyena den sites, the first recorded mention of the cave hyena in literature occurs in Kundmanns 1737 tome Rariora Naturæ et Artis, where the author misidentified a hyenas mandibular ramus as that of a calf. In 1774, Esper erroneously described hyena teeth discovered in Gailenreuth as those of a lion, bucklands findings were followed by further discoveries by Clift and Whidbey in Oreston, Plymouth. He elaborated his view in his Ossemens Fossiles, noting how the cave hyenas digital extremities were shorter and thicker than those of the spotted hyena and his views were largely accepted throughout the first half of the 19th century, finding support in de Blainville and Richard Owen among others. Further justifications in separating the two animals included differences in the portion of the lower carnassial. Writing again in 1877, he stated after comparing the two animals skulls that there are no characters of specific value. Analyses of the DNA sequences of the cytochrome b genes in both modern African and Pleistocene spotted hyenas demonstrated that the two were the same species. Kills partially processed by Neanderthals and then by cave hyenas indicate that hyenas would occasionally steal Neanderthal kills, many caves show alternating occupations by hyenas and Neanderthals. The presence of large populations in the Russian Far East may have delayed the human colonisation of North America. There is fossil evidence of humans in Middle Pleistocene Europe butchering, the cave hyena is depicted in a few examples of Upper Palaeolithic rock art in France. A painting from the Chauvet Cave depicts a hyena outlined and represented in profile, because of the specimens steeped profile, it is thought that the painting was originally meant to represent a cave bear, but was modified as a hyena

Minotaur
–
In Greek mythology, the Minotaur was a creature with the head of a bull and the body of a man or, as described by Roman poet Ovid, a being part man and part bull. The Minotaur dwelt at the center of the Labyrinth, which was an elaborate maze-like construction designed by the architect Daedalus and his son Icarus, the Minotaur was eventually killed by the Athenian hero Theseus. The term Minotaur derives from the Ancient Greek Μῑνώταυρος, a compound of the name Μίνως, in Crete, the Minotaur was known by the name Asterion, a name shared with Minos foster-father. Minotaur was originally a noun in reference to this mythical figure. The use of minotaur as a noun to refer to members of a generic species of bull-headed creatures developed much later. After he ascended the throne of the island of Crete, Minos competed with his brothers to rule, Minos prayed to Poseidon, the sea god, to send him a snow-white bull, as a sign of support. He was to kill the bull to show honor to the deity and he thought Poseidon would not care if he kept the white bull and sacrificed one of his own. To punish Minos, Poseidon made Pasiphaë, Minoss wife, fall deeply in love with the bull, Pasiphaë had craftsman Daedalus make a hollow wooden cow, and climbed inside it in order to mate with the white bull. The offspring was the monstrous Minotaur, Pasiphaë nursed him, but he grew and became ferocious, being the unnatural offspring of a woman and a beast, he had no natural source of nourishment and thus devoured humans for sustenance. Minos, after getting advice from the oracle at Delphi, had Daedalus construct a labyrinth to hold the Minotaur. Its location was near Minos palace in Knossos, the Minotaur is commonly represented in Classical art with the body of a man and the head and tail of a bull. One of the figurations assumed by the river spirit Achelous in seducing Deianira is as a man with the head of a bull, from Classical times through the Renaissance, the Minotaur appears at the center of many depictions of the Labyrinth. This alternative tradition survived into the Renaissance, and still figures in modern depictions. Androgeus, son of Minos, had killed by the Athenians. Others say he was killed at Marathon by the Cretan bull, his mothers former taurine lover, the common tradition is that Minos waged war to avenge the death of his son and won. Catullus, in his account of the Minotaurs birth, refers to another version in which Athens was compelled by the plague to pay penalties for the killing of Androgeos. Aegeus had to avert the plague caused by his crime by sending young men at the time as the best of unwed girls as a feast to the Minotaur. Minos required that seven Athenian youths and seven maidens, drawn by lots, when the third sacrifice approached, Theseus volunteered to slay the monster

Red ochre
–
Ochre (/ˈoʊkər/ OH-kər, from Greek, ὠχρός, ōkhrós, or ocher, is a natural earth pigment containing hydrated iron oxide, which ranges in color from yellow to deep orange or brown. It is also the name of the produced by this pigment. A variant of ochre containing an amount of hematite, or dehydrated iron oxide, has a reddish tint known as red ochre. Ochre is a family of pigments, which includes yellow ochre, red ochre, purple ochre, sienna. The major ingredient of all the ochres is iron oxide-hydroxide, known as limonite, which gives them a yellow color. Yellow ochre, FeO·nH 2O, is a hydrated iron hydroxide also called gold ochre Red ochre, Fe 2O3, takes its color from the mineral hematite. Purple ochre, is identical to red ochre chemically but of a different hue caused by different light diffraction properties associated with an average particle size. Brown ochre, also FeO, is a hydrated iron oxide. Sienna contains both limonite and an amount of manganese oxide, which makes it darker than ochre. Umber pigments contain a proportion of manganese which make them a dark brown. When natural sienna and umber pigments are heated, they are dehydrated and some of the limonite is transformed into hematite, giving them more reddish colors, called burnt sienna and burnt umber. Ochres are non-toxic, and can be used to make an oil paint that dries quickly, modern ochre pigments often are made using synthetic iron oxide. Pigments which use natural ochre pigments indicate it with the name PY-43 on the label, pieces of ochre engraved with abstract designs have been found at the site of the Blombos Cave in South Africa, dated to around 75,000 years ago. In Wales, the paleolithic burial called the Red Lady of Paviland from its coating of red ochre has been dated to around 33,000 years before present. Paintings of animals made with red and yellow ochre pigments have been found in sites at Pech Merle in France. The cave of Lascaux has an image of a horse colored with yellow estimated to be 17,300 years old. In Ancient Egypt, yellow was associated with gold, which was considered to be eternal, the skin and bones of the gods were believed to be made of gold. The Egyptians used yellow extensively in tomb painting, though occasionally they used orpiment

Pigment
–
A pigment is a material that changes the color of reflected or transmitted light as the result of wavelength-selective absorption. This physical process differs from fluorescence, phosphorescence, and other forms of luminescence, many materials selectively absorb certain wavelengths of light. Materials that humans have chosen and developed for use as pigments usually have properties that make them ideal for coloring other materials. A pigment must have a high tinting strength relative to the materials it colors and it must be stable in solid form at ambient temperatures. For industrial applications, as well as in the arts, permanence, pigments that are not permanent are called fugitive. Fugitive pigments fade over time, or with exposure to light, pigments are used for coloring paint, ink, plastic, fabric, cosmetics, food, and other materials. Most pigments used in manufacturing and the arts are dry colorants. This powder is added to a binder, a neutral or colorless material that suspends the pigment. A distinction is made between a pigment, which is insoluble in its vehicle, and a dye, which either is itself a liquid or is soluble in its vehicle. A colorant can act as either a pigment or a dye depending on the vehicle involved, in some cases, a pigment can be manufactured from a dye by precipitating a soluble dye with a metallic salt. The resulting pigment is called a lake pigment, the term biological pigment is used for all colored substances independent of their solubility. In 2006, around 7.4 million tons of inorganic, organic, asia has the highest rate on a quantity basis followed by Europe and North America. By 2020, revenues will have risen to approx, the global demand on pigments was roughly US$20.5 billion in 2009, around 1. 5-2% up from the previous year. It is predicted to increase in a growth rate in the coming years. The worldwide sales are said to increase up to US$24.5 billion in 2015, pigments appear the colors they are because they selectively reflect and absorb certain wavelengths of visible light. White light is an equal mixture of the entire spectrum of visible light with a wavelength in a range from about 375 or 400 nanometers to about 760 or 780 nm. When this light encounters a pigment, parts of the spectrum are absorbed by the molecules or ions of the pigment, in organic pigments such as diazo or phthalocyanine compounds the light is absorbed by the conjugated systems of double bonds in the molecule. Some of the inorganic pigments such as vermilion or cadmium yellow absorb light by transferring an electron from the ion to the positive ion

Abstract art
–
Abstract art uses a visual language of shape, form, color and line to create a composition which may exist with a degree of independence from visual references in the world. Western art had been, from the Renaissance up to the middle of the 19th century, underpinned by the logic of perspective, the arts of cultures other than the European had become accessible and showed alternative ways of describing visual experience to the artist. By the end of the 19th century many artists felt a need to create a new kind of art which would encompass the fundamental changes taking place in technology, science and philosophy. The sources from which individual artists drew their theoretical arguments were diverse, Abstract art, non-figurative art, non-objective art, and nonrepresentational art are loosely related terms. They are similar, but perhaps not of identical meaning, Abstraction indicates a departure from reality in depiction of imagery in art. This departure from accurate representation can be slight, partial, or complete, even art that aims for verisimilitude of the highest degree can be said to be abstract, at least theoretically, since perfect representation is likely to be exceedingly elusive. Artwork which takes liberties, altering for instance color and form in ways that are conspicuous, total abstraction bears no trace of any reference to anything recognizable. In geometric abstraction, for instance, one is unlikely to find references to naturalistic entities, Figurative art and total abstraction are almost mutually exclusive. But figurative and representational art often contains partial abstraction, both geometric abstraction and lyrical abstraction are often totally abstract. It is at level of visual meaning that abstract art communicates. One can enjoy the beauty of Chinese calligraphy or Islamic calligraphy without being able to read it, in Chinese painting, abstraction can be traced to the Tang dynasty painter Wang Mo, who is credited to have invented the splashed-ink painting style. While none of his paintings remain, this style is seen in some Song Dynasty Paintings. A late Song painter named Yu Jian, adept to Tiantai buddhism and his paintings show heavily misty mountains in which the shapes of the objects are barely visible and extremely simplified. This type of painting was continued by Sesshu Toyo in his later years, another instance of abstraction in Chinese painting is seen in Zhu Deruns Cosmic Circle. The painting is a reflection of the Daoist metaphysics in which chaos, in Tokugawa Japan some zen monk-painters created Enso, a circle who represents the absolute enlightenment. Usually made in one spontaneous brush stroke, it became the paradigm of the minimalist aesthetic that guided part of the zen painting, three art movements which contributed to the development of abstract art were Romanticism, Impressionism and Expressionism. Artistic independence for artists was advanced during the 19th century, patronage from the church diminished and private patronage from the public became more capable of providing a livelihood for artists. Expressionist painters explored the use of paint surface, drawing distortions and exaggerations

Ritual
–
A ritual is a sequence of activities involving gestures, words, and objects, performed in a sequestered place, and performed according to set sequence. Rituals may be prescribed by the traditions of a community, including a religious community, Rituals are characterized but not defined by formalism, traditionalism, invariance, rule-governance, sacral symbolism, and performance. Rituals are a feature of all human societies. Even common actions like hand-shaking and saying hello may be termed rituals, the field of ritual studies has seen a number of conflicting definitions of the term. One given by Kyriakidis is that a ritual is an outsiders or etic category for a set activity that, to the outsider, seems irrational, non-contiguous, or illogical. The term can be used also by the insider or emic performer as an acknowledgement that this activity can be seen as such by the uninitiated onlooker, the English word ritual derives from the Latin ritualis, that which pertains to rite. In Roman juridical and religious usage, ritus was the way of doing something, or correct performance. The word ritual is first recorded in English in 1570, there are hardly any limits to the kind of actions that may be incorporated into a ritual. Catherine Bell argues that rituals can be characterized by formalism, traditionalism, invariance, rule-governance, sacral symbolism, Ritual utilizes a limited and rigidly organized set of expressions which anthropologists call a restricted code. Maurice Bloch argues that ritual obliges participants to use this formal oratorical style, which is limited in intonation, syntax, vocabulary, loudness, in adopting this style, ritual leaders speech becomes more style than content. Because this formal speech limits what can be said, it induces acceptance, compliance, Bloch argues that this form of ritual communication makes rebellion impossible and revolution the only feasible alternative. Ritual tends to support forms of social hierarchy and authority. Rituals appeal to tradition and are concerned to repeat historical precedents accurately. Traditionalism varies from formalism in that the ritual may not be yet still makes an appeal to historical. An example is the American Thanksgiving dinner, which may not be formal, thus, the appeal to history is important rather than accurate historical transmission. Catherine Bell states that ritual is also invariant, implying careful choreography and this is less an appeal to traditionalism than a striving for timeless repetition. The key to invariance is bodily discipline, as in prayer and meditation meant to mold dispositions. This bodily discipline is frequently performed in unison, by groups, Rituals tend to be governed by rules, a feature somewhat like formalism
37.
Shamanism
–
The word shaman probably originates from the Tungusic Evenki language of North Asia. The term was introduced to the west after Russian forces conquered the shamanistic Khanate of Kazan in 1552, Mircea Eliade writes, A first definition of this complex phenomenon, and perhaps the least hazardous, will be, shamanism = technique of religious ecstasy. Shamanism encompasses the premise that shamans are intermediaries or messengers between the world and the spirit worlds. Shamans are said to treat ailments/illness by mending the soul, alleviating traumas affecting the soul/spirit restores the physical body of the individual to balance and wholeness. The shaman also enters supernatural realms or dimensions to obtain solutions to problems afflicting the community, Shamans may visit other worlds/dimensions to bring guidance to misguided souls and to ameliorate illnesses of the human soul caused by foreign elements. The shaman operates primarily within the world, which in turn affects the human world. The restoration of balance results in the elimination of the ailment, hundreds of books and academic papers on the subject have been produced, with a peer-reviewed academic journal being devoted to the study of shamanism. The word shaman probably originates from the Evenki word šamán, most likely from the dialect spoken by the Sym Evenki peoples. The Tungusic term was adopted by Russians interacting with the indigenous peoples in Siberia. It is found in the memoirs of the exiled Russian churchman Avvakum, adam Brand, a merchant from Lübeck, published in 1698 his account of a Russian embassy to China, a translation of his book, published the same year, introduced the word shaman to English speakers. The etymology of the Evenki word is sometimes connected to a Tungus root ša- to know, other scholars assert that the word comes directly from the Manchu language, and as such would be the only commonly used English word that is a loan from this language. This proposal has been thoroughly critiqued since 1917, ethnolinguist Juha Janhunen regards it as an anachronism and an impossibility that is nothing more than a far-fetched etymology. Ethnolinguists did not develop as a discipline nor achieve contact with these communities until the late 19th century, there is no single agreed-upon definition for the word shamanism among anthropologists. The English historian Ronald Hutton noted that by the dawn of the 21st century, the first of these uses the term to refer to anybody who contacts a spirit world while in an altered state of consciousness. The second definition limits the term to refer to those who contact a spirit world while in a state of consciousness at the behest of others. Problematically, scholars advocating the third view have failed to agree on what the defining technique should be, the fourth definition identified by Hutton uses shamanism to refer to the indigenous religions of Siberia and neighboring parts of Asia. According to the Golomt Center for Shamanic Studies, a Mongolian organisation of shamans, Shamans are normally called by dreams or signs which require lengthy training. However, shamanic powers may be inherited, turner and colleagues mention a phenomenon called shamanistic initiatory crisis, a rite of passage for shamans-to-be, commonly involving physical illness and/or psychological crisis

Magic (paranormal)
–
Magic or sorcery is the use of rituals, symbols, actions, gestures, and language with the aim of exploiting supernatural forces. The term magic has a variety of meanings, and there is no agreed upon definition of what it is or how it can be used. Religious scholars have defined magic in many different ways, one approach, associated with the anthropologists Edward Tylor and James G. Frazer, has magic and science be opposites. Many scholars of religion have rejected the utility of the term magic, the term magic comes from the Old Persian magu, a word that applied to a form of religious functionary about which little is known. This meaning of the term was adopted by Latin in the first century BCE. The concept was incorporated into Christian theology during the first century CE. This concept was pervasive throughout the Middle Ages, although in the modern period Italian humanists reinterpreted the term in a positive sense to establish the idea of natural magic. Both negative and positive understandings of the term were retained in Western culture over the following centuries, throughout Western history, there have been examples of individuals claiming to be practitioners of magic and referring to themselves as magicians. This trend has proliferated in the period, with a growing number of magicians appearing within the esoteric milieu. Scholars of religion have failed to agree on a definition of magic is. The subject has one of intense dispute, with some scholars criticizing the validity of the term in the first place. Even among those throughout history who have described themselves as magicians, there has been some debate among scholars as to whether to use the term magic at all. The scholar of religion Jonathan Z. Smith for example argued that it had no utility as a term that scholars should use. Religious historian Wouter Hanegraaff agreed, stating that the magic is an important object of historical research. Since the 1990s its usage among scholars has declined, within Western culture, magic has been linked to the idea of the Other. Using the term magic when discussing non-Western cultures or pre-modern forms of Western society raises problems, alternately, this term implies that all categories of magic are ethnocentric and that such Western preconceptions are an unavoidable component of scholarly research. Magic is one of the most heavily theorized concepts in the study of religion, the intellectualist approach to defining magic is associated with two prominent British anthropologists, Edward Tylor and James G. Frazer. This was an approach that viewed magic as being the theoretical opposite of science, in his 1871 book Primitive Culture, Tylor characterized magic as beliefs based on the error of mistaking ideal analogy for real analogy

Etching
–
Etching is traditionally the process of using strong acid or mordant to cut into the unprotected parts of a metal surface to create a design in intaglio in the metal. In modern manufacturing, other chemicals may be used on other types of material, as a method of printmaking, it is, along with engraving, the most important technique for old master prints, and remains in wide use today. In a number of variants such as microfabrication etching and photochemical milling it is a crucial technique in much modern technology. In traditional pure etching, a plate is covered with a waxy ground which is resistant to acid. The artist then scratches off the ground with an etching needle where he or she wants a line to appear in the finished piece. The échoppe, a tool with an oval section, is also used for swelling lines. The plate is dipped in a bath of acid, technically called the mordant or etchant. The acid bites into the metal where it is exposed, leaving behind lines sunk into the plate, the remaining ground is then cleaned off the plate. The plate is inked all over, and then the ink wiped off the surface, the plate is then put through a high-pressure printing press together with a sheet of paper. The paper picks up the ink from the lines, making a print. The process can be repeated many times, typically several hundred impressions could be printed before the shows much sign of wear. The work on the plate can also be added to by repeating the whole process, Etching has often been combined with other intaglio techniques such as engraving or aquatint. The process as applied to printmaking is believed to have been invented by Daniel Hopfer of Augsburg, Hopfer was a craftsman who decorated armour in this way, and applied the method to printmaking, using iron plates. Apart from his prints, there are two examples of his work on armour, a shield from 1536 now in the Real Armeria of Madrid. The switch to copper plates was made in Italy. On the other hand, the handling of the ground and acid need skill and experience, prior to 1100 AD, the New World Hohokam independently utilized the technique of acid etching in marine shell designs. Jacques Callot from Nancy in Lorraine made important technical advances in etching technique and he developed the échoppe, a type of etching-needle with a slanting oval section at the end, which enabled etchers to create a swelling line, as engravers were able to do. Callot also appears to have responsible for an improved, harder, recipe for the etching ground

Woolly rhinoceros
–
The woolly rhinoceros is an extinct species of rhinoceros that was common throughout Europe and northern Asia during the Pleistocene epoch and survived the last glacial period. The genus name Coelodonta means cavity tooth, the woolly rhinoceros was a member of the Pleistocene megafauna. As the last and most derived member of the Pleistocene rhinoceros lineage, stocky limbs and thick woolly pelage made it well suited to the steppe-tundra environment prevalent across the Palearctic ecozone during the Pleistocene glaciations. Like the vast majority of rhinoceroses, the plan of the woolly rhinoceros adhered to a conservative morphology. A study of 40, 000- to 70, 000-year-old DNA samples showed its closest extant relative is the Sumatran rhinoceros, the appearance of woolly rhinos is known from mummified individuals from Siberia as well as cave paintings. An adult woolly rhinoceros was typically around 3 to 3.8 metres in length, with a weight of around 1. The woolly rhinoceros could grow to be 2 m tall, the size was thus comparable to, or slightly larger than. Two horns on the skull were made of keratin, the horn being 61 cm in length, with a smaller horn between its eyes. It had thick, long fur, small ears, short, thick legs, Cave paintings suggest a wide dark band between the front and hind legs, but the feature is not universal, and the identification of pictured rhinoceroses as woolly rhinoceros is uncertain. Its shape was only from prehistoric cave drawings until a completely preserved specimen was discovered in a tar pit in Starunia. The specimen, a female, is now on display in the Polish Academy of Sciences Museum of Natural History in Kraków. Several frozen specimens have also found in Siberia, the latest in 2007. The woolly rhinoceros used its horns for defensive purposes and to attract mates, during Greenland Stadial 2 the North Sea retreated northward, as sea levels were up to 125 metres lower than today. The woolly rhinoceros roamed the exposed Doggerland and much of Northern Europe and was common in the cold, arid desert that is southern England and its geographical range expanded and contracted with the alternating cold and warm cycles, forcing populations to migrate as glaciers receded. The woolly rhinoceros co-existed with woolly mammoths and several other larger mammals of the Pleistocene megafauna. A close relative, Elasmotherium, had a southern range. It is believed they migrated there to northern Asia and Europe when the Ice Age began. Females gave birth to one or two calves, controversy has long surrounded the precise dietary preference of Coelodonta as past investigations have found both grazing and browsing modes of life to be plausible

Territory (animal)
–
In ethology, territory is the sociographical area that an animal of a particular species consistently defends against conspecifics. Animals that defend territories in this way are referred to as territorial, territoriality is only shown by a minority of species. More commonly, an individual or a group of animals has an area that it habitually uses but does not necessarily defend, this is called the home range. The home ranges of different groups of animals often overlap, or in the overlap areas, within the home range there may be a core area that no other individual group uses, but, again, this is as a result of avoidance. The ultimate function of animals inhabiting and defending a territory is to increase the fitness or inclusive fitness of the animals expressing the behaviour. Fitness in this biological sense relates to the ability of an animal to survive, the proximate functions of territory defense vary. For some animals, the reason for such behaviour is to acquire and protect food sources, nesting sites, mating areas. Territories have been classified as six types, Type A, An all-purpose territory in which all activities occur, e. g. courtship, mating, nesting and foraging Type B, A mating and nesting territory, not including most of the area used for foraging. Type C, A nesting territory which includes the nest plus an area around it. Type D, A pairing and mating territory, the type of territory defended by males in lekking species. Type F, Winter territory which typically includes foraging areas and roost sites, may be equivalent to the Type A territory, or for a migratory species, may be on the wintering grounds. Reports of territory size can be confused by a lack of distinction between home range and the defended territory, the size and shape of a territory can vary according to its purpose, season, the amount and quality of resources it contains, or the geography. The size is usually a compromise of resource needs, defense costs, predation pressure, some species of squirrels may claim as much as 10 hectares of territory. For European badgers, a home range may be as small as 30 hectares in a rural habitat. On average, a territory may be approximately 50 hectares, with main setts normally at least 500 metres apart. In urban areas, territories can be as small as 5 hectares, if they can obtain food from bird tables. Spotted hyenas have highly variable territory sizes, ranging from less than 4,000 hectares in the Ngorongoro Crater to over 100,000 hectares in the Kalahari, sanderlings forage on beaches and sandflats. When on beaches, they feed either in flocks or individual territories of 10 to 120 metres of shoreline, the time to develop territories varies between animals

Magdalenian
–
The Magdalenian refers to one of the later cultures of the Upper Paleolithic in western Europe, dating from around 17,000 to 12,000 years ago. It is named after the site of La Madeleine, a rock shelter located in the Vézère valley, commune of Tursac. The culture was geographically widespread, and later Magdalenian sites have found from Portugal in the west to Poland in the east. It is the epoch of Gabriel de Mortillets cave chronology system. The Magdalenian epoch was a one, represented by numerous stations, whose contents show progress in the arts. It was characterized by a cold and dry climate, the existence of humans in association with the reindeer, the use of bone and ivory for various implements, already begun in the preceding Solutrian epoch, was much increased, and the period is essentially a Bone age. The bone instruments are varied, spear-points, harpoon-heads, borers, hooks. Most remarkable is the evidence La Madeleine affords of prehistoric art, numbers of bones, reindeer antlers and animal teeth were found, with rude pictures, carved or etched on them, of seals, fishes, reindeer, mammoths and other creatures. The man is naked which, together with the snake, suggests a warm climate, the fauna of the Madelenian epoch seems, indeed, to have included tigers and other tropical species side by side with reindeer, blue foxes, Arctic hares and other polar creatures. Madelenian humans appears to have been of low stature, dolichocephalic, with low retreating forehead, the culture spans approximatively from 17,000 to 12,000 BP, toward the end of the last ice age. The Magdalenian tool culture is characterised by regular blade industries struck from carinated cores, typologically, the Magdalenian is divided into six phases which are generally agreed to have chronological significance. Similarly, finds from the forest of Beauregard near Paris often have been suggested as belonging to the earliest Magdalenian, the earliest Magdalenian sites are all found in France. The Epigravettian is a similar culture appearing at the time in Italy, the Balkans, Moldavia, Romania. The later phases of the Magdalenian are also synonymous with the human re-settlement of north-western Europe after the Last Glacial Maximum during the Late Glacial Maximum, research in Switzerland, southern Germany, and Belgium has provided AMS radiocarbon dating to support this. Being hunter gatherers, Magdalenians did not simply re-settle permanently in north-west Europe, however, as they often followed herds, by the end of the Magdalenian, the lithic technology shows a pronounced trend toward increased microlithisation. The bone harpoons and points have the most distinctive chronological markers within the typological sequence, as well as flint tools, the Magdalenians are best known for their elaborate worked bone, antler, and ivory that served both functional and aesthetic purposes, including perforated batons. Cave sites such as the world famous Lascaux contain the best known examples of Magdalenian cave art, in northern Spain and south west France this tool culture was superseded by the Azilian culture. In northern Europe a slightly different situation exists, with different variants of the Tjongerian techno-complex following it
