Chitin
–
Chitin n is a long-chain polymer of an N-acetylglucosamine, a derivative of glucose, and is found in many places throughout the natural world. The structure of chitin is comparable to the cellulose, forming crystalline nanofibrils or whiskers. In terms of function, it may be compared to the protein keratin, chitin has proved versatile for several medicinal, industrial and biotechnological purposes. The English word chitin comes from the French word chitine, which first appeared in 1821 and derived from the Greek word χιτών, a similar word, chiton, refers to a marine animal with a protective shell. The structure of chitin was solved by Albert Hofmann in 1929, chitin is a modified polysaccharide that contains nitrogen, it is synthesized from units of N-acetyl-D-glucosamine. Therefore, chitin may be described as cellulose with one group on each monomer replaced with an acetyl amine group. This allows for increased hydrogen bonding between adjacent polymers, giving the chitin-polymer matrix increased strength, in its pure, unmodified form, chitin is translucent, pliable, resilient, and quite tough. Combined with calcium carbonate, as in the shells of crustaceans and molluscs and this composite material is much harder and stiffer than pure chitin, and is tougher and less brittle than pure calcium carbonate. Another difference between pure and composite forms can be seen by comparing the body wall of a caterpillar to the stiff. The elaborate chitin gyroid construction in butterfly wings creates a model of optical devices having potential for innovations in biomimicry, scarab beetles in the genus Cyphochilus also utilize chitin to form extremely thin scales that diffusely reflect white light. These scales are networks of randomly ordered filaments of chitin with diameters on the scale of hundreds of nanometres, the multiple scattering of light is thought to play a role in the unusual whiteness of the scales. In addition, some wasps, such as Protopolybia chartergoides, orally secrete material containing predominantly chitin to reinforce the outer nest envelopes. Chitosan is produced commercially by deacetylation of chitin, chitosan is soluble in water, chitin producing organisms like protozoa, fungi, arthropods, and nematodes are often pathogens in other species. Keratinocytes in skin can also react to chitin or chitin fragments, according to in vitro studies, chitin is sensed by receptors, such as FIBCD1, KLRB1, REG3G, Toll-like receptor 2, CLEC7A, and mannose receptors. Plants also have receptors that can cause a response to chitin, namely chitin elicitor receptor kinase 1, the first chitin receptor was cloned in 2006. When the receptors are activated by chitin, genes related to plant defense are expressed, and jasmonate hormones are activated, commensal fungi that have ways to interact with the host immune response that as of 2016 were not well understood. Some pathogens produce chitin-binding proteins that mask the chitin they shed from these receptors, zymoseptoria tritici is an example of a fungal pathogen that has such blocking proteins, it is a major pest in wheat crops. Chitin was probably present in the exoskeletons of Cambrian arthropods such as trilobites, the oldest preserved chitin dates to the Oligocene, about 25 million years ago, consisting of a scorpion encased in amber

Archaeological site
–
Sites may range from those with few or no remains visible above ground, to buildings and other structures still in use. Beyond this, the definition and geographical extent of a site can vary widely, depending on the period studied and it is almost invariably difficult to delimit a site. It is sometimes taken to indicate a settlement of some sort although the archaeologist must also define the limits of human activity around the settlement, any episode of deposition such as a hoard or burial can form a site as well. Development-led archaeology undertaken as cultural resources management has the disadvantage of having its sites defined by the limits of the intended development, even in this case however, in describing and interpreting the site, the archaeologist will have to look outside the boundaries of the building site. According to Jess Beck in “How Do Archaeologists find sites. ”The areas with a number of artifacts are good targets for future excavation. The most common person to have found artifacts are farmers who are plowing their fields or just cleaning them up often find archaeological artifacts, many people who are out hiking and even pilots find artifacts they usually end up reporting them to archaeologist to do further investigation. When they find sites, they have to first record the area and if they have the money, there are many ways to find sites, one example can be through surveys. Surveys involve walking around analyzing the land looking for artifacts. ”This helps archaeologists in the future. In case there was no time, or money during the finding of the site, archaeologists can come back, archaeologist can also sample randomly within a given area of land as another form of conducting surveys. Surveys are very useful, according to Jess Beck, “it can tell you where people were living at different points in the past. ”Geophysics is a branch of survey becoming more and more popular in archaeology, because it uses different types of instruments to investigate features below the ground surface. It is not as reliable, because although they can see what is under the surface of the ground it does not produce the best picture, Archaeologists have to still dig up the area in order to uncover the truth. There are also two most common types of survey, which is, magnetometer and ground penetrating radar. Magnetometry is the technique of measuring and mapping patterns of magnetism in the soil and it uses an instrument called a magnetometer which is required to measure and map traces of soil magnetism. The ground penetrating radar is a method that uses radar pulses to image the subsurface and it uses electro magnetic radiation in the microwave band of the radio spectrum, and detects the reflected signals from subsurface structures. There are many tools that can be used to find artifacts. This tool is helpful to archaeologists who want to explore in a different area. They can use this tool to see what has already been discovered, with this information available, archaeologists can expand their research and add more to what has already been found. Traditionally, sites are distinguished by the presence of artifacts and features

Formative stage
–
It is the third of five stages defined by Gordon Willey and Philip Phillips in their 1958 book Method and Theory in American Archaeology. There are alternative classification systems, and this ranking would overlap what others classify as the Woodland period cultures, cultures of the Formative Stage are supposed to possess the technologies of pottery, weaving, and developed food production. Social organization is supposed to involve permanent towns and villages, as well as the first ceremonial centers, ideologically, an early priestly class or theocracy is often present or in development. Examples of cultures considered to be Formative include the Adena, Olmec, Old Copper, Oasisamerica, Woodland, sometimes also referred to as the Pre-Classic stage, it followed the Archaic stage and was superseded by the Classic stage

Processual archaeology
–
This idea implied that the goals of archaeology were, in fact, the goals of anthropology, which were to answer questions about humans and human society. All they felt could be done was to catalogue, describe, colin Renfrew, a proponent of the new processual archaeology, observed in 1987 that it focuses attention on the underlying historical processes which are at the root of change. Archaeology, he noted has learnt to speak with authority and accuracy about the ecology of past societies, their technology, their economic basis. Now it is beginning to interest itself in the ideology of early communities, their religions, the theoretical frame at the heart of processual archaeology is cultural evolutionism. Processual archaeologists are, in almost all cases, cultural evolutionists and it is from this perspective that they believe they can understand past cultural systems through the remains they left behind. This is because processual archaeologists adhere to Leslie Whites theory that culture can be defined as the means of environmental adaptation for humans. In other words, they study cultural adaptation to environmental rather than the bodily adaptation over generations. This focus on environmental adaptation is based on the cultural ecology, as exosomatic adaptation, culture is determined by environmental constraints. The result of this is that processual archaeologists propose that cultural change happens within a predictable framework, moreover, since that framework is predictable, then science is the key to unlocking how those components interacted with the cultural whole. Thus one should be able to completely reconstruct these cultural processes. Hence came the name processual archaeology and its practitioners were also called new archaeologists. Methodologically, the advocates of the New Archaeology had to come up with ways of analyzing the remains in a more scientific fashion. The problem was no framework for this kind of analysis existed. Different researchers had different approaches to this problem, Lewis Binford felt that ethno-historical information was necessary to facilitate an understanding of archaeological context. Ethno-historical research involves living and studying the life of those who would have used the artifacts - or at least a similar culture, the new methodological approaches of the processual research paradigm include logical positivism, the use of quantitative data, and the hypothetico-deductive model. Systems theory has proved to be a bag for archaeology as a whole. It works well when trying to describe how elements of a culture interact, from some obvious reasoning he proceeded to some radically new conclusions. As a result, he argued, archaeology had suffered a loss of innocence as archaeologists became sceptical of the work of their forebears, processualisms development transformed archaeology, and is sometimes called the New Archaeology

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

Rijksdienst voor het Cultureel Erfgoed
–
Rijksdienst voor het Cultureel Erfgoed often abbreviated as Cultureel Erfgoed, is a Dutch heritage organisation working for the protection and conservation of National Heritage Sites. It is located in Amersfoort, province of Utrecht, Cultureel Erfgoed is a department of the Dutch Ministry of Education, Culture and Science. They also subsidize grants in the fields of both movable and immovable cultural heritage, registered city or village views considered to be important to the countrys heritage are also protected by the Rijksdienst voor Cultureel Erfgoed. In 1875 the Dutch Ministry of Internal Affairs founded the department Kunsten en Wetenschap, in 1947 this organisation was renamed to the Rijksdienst voor de Monumentenzorg. The archeological and cultural property departments merged in 2006 and became the Rijksdienst voor Archeologie, in 2009 this organisation was renamed to the Rijksdienst voor het Cultureel Erfgoed it moved into a new building in Amersfoort. In April/May 2011 the RCE released its image collection of 550,000 images on beeldbank. cultureelerfgoed. nl, in September 2012 the first uploads to Wikimedia Commons were made. In December 2012 a bot was started to upload images

Taphonomy
–
Taphonomy is the study of decaying organisms over time and how they may become fossilized. e. Taphonomists study such phenomena as biostratinomy, decomposition, diagenesis, one motivation behind taphonomy is to better understand biases present in the fossil record. During the late century, taphonomic data began to be applied to other paleontological subfields such as paleobiology, paleoceanography, ichnology. Archaeologists study taphonomic processes in order to determine how plant and animal remains accumulate and this is critical to determining whether these remains are associated with human activity. In addition, taphonomic processes may alter biological remains after they are deposited at a site, some remains survive better than others over time, and can therefore bias an excavated collection. Forensic taphonomy is concerned with the study of the decomposition of human remains, Experimental taphonomy testing usually consists of exposing the remains of organisms to various altering processes, and then examining the effects of the exposure. Taphonomy has undergone an explosion of interest since the 1980s, with focusing on certain areas. Microbial, biogeochemical, and larger-scale controls on the preservation of different tissue types, in particular, covered within this field is the dominance of biological versus physical agents in the destruction of remains from all major taxonomic groups. Processes that concentrate biological remains, especially the degree to which different types of assemblages reflect the species composition, the spatio-temporal resolution and ecological fidelity of species assemblages, particularly the relatively minor role of out-of-habitat transport contrasted with the major effects of time-averaging. The Mars Science Laboratory mission objectives evolved from assessment on ancient Mars habitability to developing predictive models on taphonomy. It has been suggested that biominerals could be important indicators of extraterrestrial life, furthermore, organic components that are often associated with biominerals are believed to play crucial roles in both pre-biotic and biotic reactions. The search for evidence of habitability, taphonomy, and organic carbon on the planet Mars is now a primary NASA objective, because of the very select processes that cause preservation, not all organisms have the same chance of being preserved. Any factor that affects the likelihood that an organism is preserved as a fossil is a source of bias. Some of the most common sources of bias are listed below and this perhaps represents the biggest source of bias in the fossil record. First and foremost, organisms that contain hard parts have a far greater chance of being represented in the record than organisms consisting of soft tissue only. As a result, animals with bones or shells are overrepresented in the fossil record, many animals that moult, on the other hand, are overrepresented, as one animal may leave multiple fossils due to its discarded body parts. Among plants, wind-pollinated species produce so much more pollen than animal-pollinated species, most fossils form in conditions where material is deposited to the bottom of water bodies. In continental environments, fossilization is especially likely in small lakes that fill in with organic and inorganic material

Anthropology
–
Anthropology is the study of various aspects of humans within past and present societies. Social anthropology and cultural anthropology study the norms and values of societies, linguistic anthropology studies how language affects social life. Biological or physical anthropology studies the development of humans. The abstract noun anthropology is first attested in reference to history and its present use first appeared in Renaissance Germany in the works of Magnus Hundt and Otto Casmann. Their New Latin anthropologia derived from the forms of the Greek words ánthrōpos and lógos. It began to be used in English, possibly via French anthropologie, various short-lived organizations of anthropologists had already been formed. The Société Ethnologique de Paris, the first to use Ethnology, was formed in 1839 and its members were primarily anti-slavery activists. When slavery was abolished in France in 1848 the Société was abandoned and these anthropologists of the times were liberal, anti-slavery, and pro-human-rights activists. Anthropology and many other current fields are the results of the comparative methods developed in the earlier 19th century. For them, the publication of Charles Darwins On the Origin of Species was the epiphany of everything they had begun to suspect, Darwin himself arrived at his conclusions through comparison of species he had seen in agronomy and in the wild. Darwin and Wallace unveiled evolution in the late 1850s, there was an immediate rush to bring it into the social sciences. When he read Darwin he became a convert to Transformisme. His definition now became the study of the group, considered as a whole, in its details. Broca, being what today would be called a neurosurgeon, had taken an interest in the pathology of speech and he wanted to localize the difference between man and the other animals, which appeared to reside in speech. He discovered the speech center of the brain, today called Brocas area after him. The title was translated as The Anthropology of Primitive Peoples. The last two volumes were published posthumously, Waitz defined anthropology as the science of the nature of man. By nature he meant matter animated by the Divine breath, i. e. he was an animist and he stresses that the data of comparison must be empirical, gathered by experimentation

Anthrozoology
–
Anthrozoology is the subset of ethnobiology that deals with interactions between humans and other animals. It is a field that overlaps with other disciplines including anthropology, ethnology, medicine, psychology, veterinary medicine. A major focus of research is the quantifying of the positive effects of human-animal relationships on either party. It includes scholars from fields such as anthropology, sociology, biology, history, the interaction and enhancement within captive animal interactions. In the UK, the University of Exeter runs an MA in Anthrozoology which explores human-animal interactions from anthropological perspectives, there are now three primary lists for HAS scholars and students—H-Animal, the Human-Animal Studies listserv, and NILAS, as well as the Critical Animal Studies list. There are now over a dozen journals covering HAS issues, many of them founded in the last decade, and hundreds of HAS books, most of them published in the last decade. Brill, Berg, Johns Hopkins, Purdue, Columbia, Reaktion, Palgrave-McMillan, University of Minnesota, University of Illinois, beginning in 2011, ASI has partnered with Wesleyan Animal Studies, who will be hosting the fellowship in conjunction with ASI. There are also a handful of HAS conferences per year, including organized by ISAZ and NILAS. Finally, there are more HAS courses being taught now than ever before, the ASI website lists over 300 courses in twenty-nine disciplines at over 200 colleges and universities, not including over 100 law school courses.

Biology
–
Biology is a natural science concerned with the study of life and living organisms, including their structure, function, growth, evolution, distribution, identification and taxonomy. Modern biology is a vast and eclectic field, composed of branches and subdisciplines. However, despite the broad scope of biology, there are certain unifying concepts within it that consolidate it into single, coherent field. In general, biology recognizes the cell as the unit of life, genes as the basic unit of heredity. It is also understood today that all organisms survive by consuming and transforming energy and by regulating their internal environment to maintain a stable, the term biology is derived from the Greek word βίος, bios, life and the suffix -λογία, -logia, study of. The Latin-language form of the term first appeared in 1736 when Swedish scientist Carl Linnaeus used biologi in his Bibliotheca botanica, the first German use, Biologie, was in a 1771 translation of Linnaeus work. In 1797, Theodor Georg August Roose used the term in the preface of a book, karl Friedrich Burdach used the term in 1800 in a more restricted sense of the study of human beings from a morphological, physiological and psychological perspective. The science that concerns itself with these objects we will indicate by the biology or the doctrine of life. Although modern biology is a recent development, sciences related to. Natural philosophy was studied as early as the ancient civilizations of Mesopotamia, Egypt, the Indian subcontinent, however, the origins of modern biology and its approach to the study of nature are most often traced back to ancient Greece. While the formal study of medicine back to Hippocrates, it was Aristotle who contributed most extensively to the development of biology. Especially important are his History of Animals and other works where he showed naturalist leanings, and later more empirical works that focused on biological causation and the diversity of life. Aristotles successor at the Lyceum, Theophrastus, wrote a series of books on botany that survived as the most important contribution of antiquity to the plant sciences, even into the Middle Ages. Scholars of the medieval Islamic world who wrote on biology included al-Jahiz, Al-Dīnawarī, who wrote on botany, biology began to quickly develop and grow with Anton van Leeuwenhoeks dramatic improvement of the microscope. It was then that scholars discovered spermatozoa, bacteria, infusoria, investigations by Jan Swammerdam led to new interest in entomology and helped to develop the basic techniques of microscopic dissection and staining. Advances in microscopy also had a impact on biological thinking. In the early 19th century, a number of biologists pointed to the importance of the cell. Thanks to the work of Robert Remak and Rudolf Virchow, however, meanwhile, taxonomy and classification became the focus of natural historians

Ecology
–
Ecology is the scientific analysis and study of interactions among organisms and their environment. It is a field that includes biology, geography. Ecology includes the study of interactions that organisms have with other, other organisms. Ecosystems are composed of dynamically interacting parts including organisms, the communities make up. Ecosystem processes, such as production, pedogenesis, nutrient cycling. These processes are sustained by organisms with specific life history traits, biodiversity, which refers to the varieties of species, genes, and ecosystems, enhances certain ecosystem services. Ecology is not synonymous with environment, environmentalism, natural history and it is closely related to evolutionary biology, genetics, and ethology. An important focus for ecologists is to improve the understanding of how biodiversity affects ecological function, Ecology is a human science as well. For example, the Circles of Sustainability approach treats ecology as more than the environment out there and it is not treated as separate from humans. Organisms and resources compose ecosystems which, in turn, maintain biophysical feedback mechanisms that moderate processes acting on living and non-living components of the planet, the word ecology was coined in 1866 by the German scientist Ernst Haeckel. Ecological thought is derivative of established currents in philosophy, particularly from ethics and politics, ancient Greek philosophers such as Hippocrates and Aristotle laid the foundations of ecology in their studies on natural history. Modern ecology became a more rigorous science in the late 19th century. Evolutionary concepts relating to adaptation and natural selection became the cornerstones of modern ecological theory, the scope of ecology contains a wide array of interacting levels of organization spanning micro-level to a planetary scale phenomena. Ecosystems, for example, contain abiotic resources and interacting life forms, an ecosystems area can vary greatly, from tiny to vast. A single tree is of consequence to the classification of a forest ecosystem. Several generations of a population can exist over the lifespan of a single leaf. Each of those aphids, in turn, support diverse bacterial communities, biodiversity describes the diversity of life from genes to ecosystems and spans every level of biological organization. The term has several interpretations, and there are ways to index, measure, characterize

Ethnography
–
Ethnography is the systematic study of people and cultures. It is designed to explore cultural phenomena where the researcher observes society from the point of view of the subject of the study, an ethnography is a means to represent graphically and in writing the culture of a group. The word can thus be said to have a double meaning, the resulting field study or a case report reflects the knowledge and the system of meanings in the lives of a cultural group. The typical ethnography is a study and so includes a brief history, and an analysis of the terrain, the climate. In all cases it should be reflexive, make a contribution toward the understanding of the social life of humans, have an aesthetic impact on the reader. An ethnography records all observed behavior and describes all symbol-meaning relations, the word ethnography is derived from the Greek ἔθνος, meaning a company, later a people, nation and -graphy meaning field of study. Ethnographic studies focus on large groups of people who interact over time. Ethnography is a design, where the researcher explains about shared learnt patterns of values, behaviour, beliefs. The field of anthropology originated from Europe and England designed in late 19th century and it spread its roots to the United States at the beginning of the 20th century. Some of the main contributors like EB Tylor from Britain and Lewis H Morgan, franz Boas, Bronislaw Malinowski, Ruth Benedict and Margaret Mead, were a group of researchers from United States who contributed the idea of cultural relativism to the literature. He gives the point of the native and this became the origin of field work. Since Malinowski was very firm with his approach he applied it practically and he was interested in learning the language of the islanders and stayed there for a long time doing his field work. The field of ethnography became very popular in the late 19th century, again, in the latter part of the 19th century, the field of anthropology became a good support for scientific formation. Though the field was flourishing it had a lot of threat to encounter, post colonialism, the research climate shifted towards post-modernism and feminism. Therefore, the field of anthropology moved into discipline of social science, gerhard Friedrich Müller developed the concept of ethnography as a separate discipline whilst participating in the Second Kamchatka Expedition as a professor of history and geography. Whilst involved in the expedition, he differentiated Völker-Beschreibung as an area of study. This became known as ethnography, following the introduction of the Greek neologism ethnographia by Johann Friedrich Schöpperlin, there are different forms of ethnography, confessional ethnography, life history, feminist ethnography etc. Two popular forms of ethnography are realist ethnography and critical ethnography, realist ethnography, is a traditional approach used by cultural anthropologists

Paleopathology
–
Paleopathology, also spelled palaeopathology, is the study of ancient diseases. Studying pathologies, these abnormalities in individuals and systems, may be intrinsic to the system itself or caused by an extrinsic factor. Any living organism can have a pathology, studies have historically focused on humans, but there is no evidence that humans are more prone to pathologies than any other animal. The majority of the work has historically been done by anthropologists studying diseases in ancient cultures, medically trained professionals have also made substantial contributions, especially in modern comparative studies. Paleontologists have sporadically contributed to the field, focusing on non-avian dinosaurs, humans have always been interested in deviations from health. Ancient texts that are thousands of years old record instances of such as leprosy. Historically, disease has often been correlated with morality, but this view has gradually given way to modern disease theory, the true genesis of the field of human palaeopathology is generally considered to have occurred between the mid nineteenth century and World War I. This clarification included a review of human paleopathology published by H. U, williams in 1929 and a book published by Pales in 1930 on paleopathology and comparative pathology. It was at point that palaeopathology can truly be considered to have become a scientific discipline. Arthropathies, that is joint diseases such as osteoarthritis and gout, are not uncommon. The first exhaustive reference of human paleopathology evidence in skeletal tissue was published in 1976 by Ortner & Putschar, in identifying pathologies, physical anthropologists rely heavily on good archaeological documentation regarding location, age of site and other environmental factors. These provide the foundation on which further analysis is built and are required for accurate populations studies, from there, the paleopathology researcher determines a number of key biological indicators on the specimen including age and sex. These provide a foundation for further analysis of material and evaluation of lesions or other anomalies identified. Archaeologists increasingly use paleopathology as an important main tool for understanding the lives of ancient peoples, for example, cranial deformation is evident in the skulls of the Maya, where a straight line between nose and forehead may have been preferred over an angle or slope. There is also evidence for trepanation, or drilling holes in the cranium, partially or completely healed trepanations indicate that this procedure was often survived. Several diseases are present in the archaeological record, through archaeological evaluation these diseases can be identified and sometimes can explain the cause of death for certain individuals. Aside from looking at sex, age, etc. of a skeleton, tuberculosis is presumed to have been transmitted from domesticated cattle to humans through ingestion of contaminated meats and the drinking of contaminated milk. It is also possible to contract tuberculosis through contact with infected persons, when an infected person coughs, they eject infected mucus from their body which can possibly infect those close by

Paleontology
–
Paleontology or palaeontology is the scientific study of life that existed prior to, and sometimes including, the start of the Holocene Epoch. It includes the study of fossils to determine organisms evolution and interactions with each other, paleontological observations have been documented as far back as the 5th century BC. The science became established in the 18th century as a result of Georges Cuviers work on comparative anatomy, and developed rapidly in the 19th century. The term itself originates from Greek παλαιός, palaios, i. e. old, ancient, ὄν, on, i. e. being, creature and λόγος, logos, i. e. speech, thought, study. Paleontology lies on the border between biology and geology, but differs from archaeology in that it excludes the study of modern humans. It now uses techniques drawn from a range of sciences, including biochemistry, mathematics. The final quarter of the 20th century saw the development of molecular phylogenetics, molecular phylogenetics has also been used to estimate the dates when species diverged, but there is controversy about the reliability of the molecular clock on which such estimates depend. The simplest definition is the study of ancient life, paleontology is one of the historical sciences, along with archaeology, geology, astronomy, cosmology, philology and history itself. This means that it aims to describe phenomena of the past, hence it has three main elements, description of the phenomena, developing a general theory about the causes of various types of change, and applying those theories to specific facts. Sometimes the smoking gun is discovered by an accident during other research. Paleontology lies on the boundary between biology and geology since paleontology focuses on the record of past life but its source of evidence is fossils. In addition paleontology often uses techniques derived from other sciences, including biology, osteology, ecology, chemistry, techniques developed in engineering have been used to analyse how ancient organisms might have worked, for example how fast Tyrannosaurus could move and how powerful its bite was. As knowledge has increased, paleontology has developed specialised subdivisions, vertebrate paleontology concentrates on fossils of vertebrates, from the earliest fish to the immediate ancestors of modern mammals. Invertebrate paleontology deals with fossils of such as molluscs, arthropods. Paleobotany focuses on the study of plants, but traditionally includes the study of fossil algae. Palynology, the study of pollen and spores produced by plants and protists. Micropaleontology deals with all microscopic fossil organisms, regardless of the group to which they belong, one example is the development of oxygenic photosynthesis by bacteria, which hugely increased the productivity and diversity of ecosystems. This also caused the oxygenation of the atmosphere, together, these were a prerequisite for the evolution of the most complex eukaryotic cells, from which all multicellular organisms are built

Paleozoology
–
Perhaps the best known macrofossils group is the dinosaurs. This is because hard organic parts, such as bones, teeth, and shells resist decay, exclusively soft-bodied animals—such as jellyfish, flatworms, nematodes, and insects—are consequently rarely fossilized, as these groups do not produce hard organic parts. Vertebrate paleozoology refers to the use of morphological, temporal, vertebrates are classified as a subphylum of Chordata, a phylum used to classify species adhering to a rod-shaped, flexible body type called a notochord. They differ from other phyla in that other phyla may have cartilage or cartilage-like tissues forming a sort of skeleton, evolutionary origins of vertebrates as well as the phylum Chordata have not been scientifically determined. Many believe vertebrates diverged from an ancestor of chordates and echinoderms. This belief is supported by the prehistoric marine creature Amphioxus. Amphioxus does not possess bone, making it an invertebrate, but it has common features with vertebrates including a segmented body and this could imply that Amphioxus is a transitional form between an early chordate, echinoderm or common ancestor, and vertebrates. Quantitative paleozoology is a process of taking a census of fossil types rather than inventory and they differ in that inventory refers to a detailed log of individual fossils, whereas census attempts to group individual fossils to tally the total number of a species. This information can be used to determine which species were most dominant, in the early 1930s, paleontologists Chester Stock and Hildegarde Howard devised special units for quantitative paleozoology and quantitative paleontology. The first unit used, Number of Identified Species, specified exact quantity of fossils from a species recorded. Stock and Howard determined this unit to be problematic for quantitative purposes as an excess of a small fossil—such as teeth—could exaggerate quantity of the species, there was also an amount of confusion as to whether bone fragments should be assembled and counted as one bone or tallied individually. Stock and Howard then devised the Minimum Number of Individuals, which estimated the number of animals needed to produce the fossils recorded. Five would thus be the MNI, in rare cases where enough of a collection of fossils can be assembled into individuals as to provide an accurate number of individuals, the unit used is Actual Number of Individuals, or ANI. Another unit commonly used in quantitative paleozoology is biomass, biomass is defined as the amount of tissue in an area or from a species. It is calculated by estimating an average based on similar modern species. This yields an estimate of how much the population of a species may have weighed. A similar measurement to biomass is meat weight, to determine meat weight, MNI is multiplied by the amount of meat an individual is thought to have provided, then multiplied by the percentage of that meat thought to be edible. This gives an estimate of “pounds of usable meat” per individual which might have been harvested by prehistoric hunters, for example, a male Wapiti has an average weight of 400 kg, and in a particular study, the MNI of Wapiti was found to be 10

Zoology
–
The term is derived from Ancient Greek ζῷον, zōion, i. e. animal and λόγος, logos, i. e. knowledge, study. The history of zoology traces the study of the kingdom from ancient to modern times. This ancient work was developed in the Middle Ages by Muslim physicians. During the Renaissance and early period, zoological thought was revolutionized in Europe by a renewed interest in empiricism. Microscopy revealed the unknown world of microorganisms, laying the groundwork for cell theory. The growing importance of natural theology, partly a response to the rise of mechanical philosophy, over the 18th and 19th centuries, zoology became an increasingly professional scientific discipline. Naturalists began to reject essentialism and consider the importance of extinction, cell theory provided a new perspective on the fundamental basis of life. These developments, as well as the results from embryology and paleontology, were synthesized in Charles Darwins theory of evolution by natural selection. In 1859, Darwin placed the theory of evolution on a new footing, by his discovery of a process by which organic evolution can occur. Darwin gave new direction to morphology and physiology, by uniting them in a biological theory. The end of the 19th century saw the fall of spontaneous generation, cell biology studies the structural and physiological properties of cells, including their behavior, interactions, and environment. This is done on both the microscopic and molecular levels, for single-celled organisms such as bacteria as well as the cells in multicellular organisms such as humans. Understanding the structure and function of cells is fundamental to all of the biological sciences, the similarities and differences between cell types are particularly relevant to molecular biology. Anatomy considers the forms of macroscopic structures such as organs and organ systems and it focuses on how organs and organ systems work together in the bodies of humans and animals, in addition to how they work independently. Anatomy and cell biology are two studies that are related, and can be categorized under structural studies. Physiology studies the mechanical, physical, and biochemical processes of living organisms by attempting to understand how all of the function as a whole. The theme of structure to function is central to biology, for example, what is learned about the physiology of yeast cells can also apply to human cells. The field of animal physiology extends the tools and methods of physiology to non-human species

Animal husbandry
–
Animal husbandry is the management and care of farm animals by human beings, in which genetic qualities and behavior, considered to be advantageous to humans, are further developed. The term can refer to the practice of breeding and raising livestock to promote desirable traits in animals for utility, sport, pleasure. Animal husbandry has been practiced for thousands of years since the first domestication of animals, selective breeding for desired traits was first established as a scientific practice by Robert Bakewell during the British Agricultural Revolution in the 18th century. One of his most important breeding programs was with sheep, using native stock, he was able to quickly select for large, yet fine-boned sheep, with long, lustrous wool. The Lincoln Longwool was improved by Bakewell and in turn the Lincoln was used to develop the subsequent breed, named the New Leicester and it was hornless and had a square, meaty body with straight top lines. These sheep were exported widely and have contributed to modern breeds. Under his influence, English farmers began to breed cattle for use primarily as beef for consumption -, long-horned heifers were crossed with the Westmoreland bull to eventually create the Dishley Longhorn. Over the following decades, farm animals increased dramatically in size, in 1700, the average weight of a bull sold for slaughter was 370 pounds. By 1786, that weight had more than doubled to 840 pounds, in more modern times herds are tended on horses, all-terrain vehicles, motorbikes, four-wheel drive vehicles, and helicopters, depending on the terrain and livestock concerned. Today, herd managers often oversee thousands of animals and many staff, farms, stations and ranches may employ breeders, herd health specialists, feeders, and milkers to help care for the animals. Techniques such as artificial insemination and embryo transfer are used today, not only as methods to guarantee that females breed regularly. This may be done by transplanting embryos from high-quality females into lower-quality surrogate mothers - freeing up the higher-quality mother to be reimpregnated and this practice vastly increases the number of offspring which may be produced by a small selection of the best quality parent animals. On one hand, this improves the ability of the animals to feed to meat, milk, or fiber more efficiently. On the other, it decreases genetic diversity, increasing the severity of disease outbreaks among other risks. The semi-natural, unfertilized pastures formed by traditional methods in Europe, were managed and maintained by the grazing and mowing of livestock. Animal agriculture is responsible for 20%-33% of all fresh water consumption in the world today, livestock or livestock feed occupies 1/3 of the earth’s ice-free land. Animal agriculture is the cause of species extinction, ocean dead zones, water pollution. Animal agriculture contributes to species extinction in many ways, the widespread use of pesticides, herbicides and chemical fertilizers used in the production of feed crops often interferes with the reproductive systems of animals and poison waterways

Belief
–
Belief is the state of mind in which a person thinks something to be the case, with or without there being empirical evidence to prove that something is the case with factual certainty. Another way of defining belief sees it as a representation of an attitude positively oriented towards the likelihood of something being true. In the context of Ancient Greek thought, two related concepts were identified with regards to the concept of belief, pistis and doxa, simplified, we may say that pistis refers to trust and confidence, while doxa refers to opinion and acceptance. The English word orthodoxy derives from doxa, Jonathan Leicester suggests that belief has the purpose of guiding action rather than indicating truth. In epistemology, philosophers use the belief to refer to personal attitudes associated with true or false ideas. However, belief does not require active introspection and circumspection, for example, we never ponder whether or not the sun will rise. We simply assume the sun will rise, since belief is an important aspect of mundane life, according to Eric Schwitzgebel in the Stanford Encyclopedia of Philosophy, a related question asks, how a physical organism can have beliefs. Epistemology is concerned with delineating the boundary between justified belief and opinion, and involved generally with a philosophical study of knowledge. The primary problem in epistemology is to exactly what is needed in order for us to have knowledge. Plato dismisses this possibility of a relation between belief and knowledge even when the one who opines grounds his belief on the rule. Among American epistemologists, Gettier and Goldman, have questioned the true belief definition. Mainstream psychology and related disciplines have traditionally treated belief as if it were the simplest form of mental representation, philosophers have tended to be more abstract in their analysis, and much of the work examining the viability of the belief concept stems from philosophical analysis. The concept of belief presumes a subject and an object of belief, Beliefs are sometimes divided into core beliefs and dispositional beliefs. For example, if asked do you believe tigers wear pink pajamas, a person might answer that they do not, despite the fact they may never have thought about this situation before. This has important implications for understanding the neuropsychology and neuroscience of belief, if the concept of belief is incoherent, then any attempt to find the underlying neural processes that support it will fail. Jerry Fodor is one of the defenders of this point of view. Most notably, philosopher Stephen Stich has argued for this understanding of belief. In these cases science hasnt provided us with a detailed account of these theories

Cultural diplomacy
–
In essence cultural diplomacy reveals the soul of a nation, which in turn creates influence. Though often overlooked, cultural diplomacy can and does play an important role in achieving national security aims, culture is a set of values and practices that create meaning for society. This includes both high culture and popular culture and this is what governments seek to show foreign audiences when engaging in cultural diplomacy. It is a type of power, which is the ability to get what you want through attraction rather than coercion or payments. It arises from a culture, political ideals and policies. This indicates that the value of culture is its ability to attract foreigners to a nation, Cultural diplomacy is also a component of public diplomacy. Public diplomacy is enhanced by a society and culture, but simultaneously public diplomacy helps to amplify and advertise that society. It could be argued that the component of public diplomacy can only be fully effective where there is already a relationship that gives credibility to the information being relayed. This comes from knowledge of the others culture, Cultural diplomacy has been called the linchpin of public diplomacy because cultural activities have the possibility to demonstrate the best of a nation. In this way, cultural diplomacy and public diplomacy are intimately linked, if that is correct, cultural diplomacy can only be said to take place when formal diplomats, serving national governments, try to shape and channel this natural flow to advance national interests. Cultural diplomacy attempts to manage the environment by utilizing these sources and achievements. An important aspect of this is listening- cultural diplomacy is meant to be a two-way exchange and this exchange is then intended to foster a mutual understanding and thereby win influence within the target nation. Cultural diplomacy derives its credibility not from being close to government institutions and it is seen as a silent weapon in gaining control over another nation with the use of non-violent methods to perpetrate a relationship of mutual understanding and support among the countries involved. Ultimately, the goal of diplomacy is to influence a foreign audience and use that influence. In turn, cultural diplomacy can help a nation better understand the nation it is engaged with. Cultural diplomacy is a way of conducting international relations without expecting anything in return in the way that traditional diplomacy typically expects, generally, cultural diplomacy is more focused on the longer term and less on specific policy matters. The intent is to build up influence over the term for when it is needed by engaging people directly. This influence has implications ranging from security to increasing tourism

Diet (nutrition)
–
In nutrition, diet is the sum of food consumed by a person or other organism. The word diet often implies the use of intake of nutrition for health or weight-management reasons. Although humans are omnivores, each culture and each person holds some food preferences or some food taboos and this may be due to personal tastes or ethical reasons. Individual dietary choices may be more or less healthy, complete nutrition requires ingestion and absorption of vitamins, minerals, and food energy in the form of carbohydrates, proteins, and fats. Dietary habits and choices play a significant role in the quality of life, health, some cultures and religions have restrictions concerning what foods are acceptable in their diet. For example, only Kosher foods are permitted by Judaism, although Buddhists are generally vegetarians, the practice varies and meat-eating may be permitted depending on the sects. In Hinduism, vegetarianism is the ideal, jains are strictly vegetarian and consumption of roots is not permitted. Raw foodism is another contemporary trend and these diets may require tuning or supplementation such as vitamins to meet ordinary nutritional needs. A particular diet may be chosen to seek weight loss or weight gain, changing a subjects dietary intake, or going on a diet, can change the energy balance and increase or decrease the amount of fat stored by the body. Some foods are recommended, or even altered, for conformity to the requirements of a particular diet. These diets are recommended in conjunction with exercise. Specific weight loss programs can be harmful to health, while others may be beneficial, the terms healthy diet and diet for weight management are often related, as the two promote healthy weight management. Having a healthy diet is a way to prevent health problems, and will provide the body with the balance of vitamins, minerals. An eating disorder is a disorder that interferes with normal food consumption. It is defined by abnormal eating habits that may involve either insufficient or excessive diet, a healthy diet may improve or maintain optimal health. In developed countries, affluence enables unconstrained caloric intake and possibly inappropriate food choices, health agencies recommend that people maintain a normal weight by limiting consumption of energy-dense foods and sugary drinks, eat plant-based food, limit red and processed meat, and limit alcohol.

Nutrition
–
Nutrition is the science that interprets the interaction of nutrients and other substances in food in relation to maintenance, growth, reproduction, health and disease of an organism. It includes food intake, absorption, assimilation, biosynthesis, catabolism, the diet of an organism is what it eats, which is largely determined by the availability, the processing and palatability of foods. A healthy diet includes preparation of food and storage methods that preserve nutrients from oxidation, heat or leaching, and they also provide preventive and therapeutic programs at work places, schools and similar institutions. Government regulation especially in terms of licensing, is less universal for the CCN than that of RD or RDN. Another advanced Nutrition Professional is a Certified Nutrition Specialist or CNS and these Board Certified Nutritionists typically specialize in obesity and chronic disease. In order to become certified, potential CNS candidate must pass an examination. This exam covers specific domains within the health sphere including, Clinical Intervention, a poor diet can cause the wasting of kwashiorkor in acute cases, and the stunting of marasmus in chronic cases of malnutrition. The first recorded dietary advice, carved into a Babylonian stone tablet in about 2500 BC, scurvy, later found to be a vitamin C deficiency, was first described in 1500 BC in the Ebers Papyrus. According to Walter Gratzer, the study of nutrition probably began during the 6th century BC, in China, the concept of Qi developed, a spirit or wind similar to what Western Europeans later called pneuma. Food was classified into hot and cold in China, India, Malaya, humours developed perhaps first in China alongside qi. Ho the Physician concluded that diseases are caused by deficiencies of elements, the first recorded nutritional experiment with human subjects is found in the Bibles Book of Daniel. Daniel and his friends were captured by the king of Babylon during an invasion of Israel, selected as court servants, they were to share in the kings fine foods and wine. But they objected, preferring vegetables and water in accordance with their Jewish dietary restrictions, the kings chief steward reluctantly agreed to a trial. Daniel and his friends received their diet for ten days and were compared to the kings men. Appearing healthier, they were allowed to continue with their diet, around 475 BC, Anaxagoras stated that food is absorbed by the human body and, therefore, contains homeomerics, suggesting the existence of nutrients. Around 400 BC, Hippocrates, who recognized and was concerned with obesity, the works that are still attributed to him, Corpus Hippocraticum, called for moderation and emphasized exercise. Salt, pepper and other spices were prescribed for various ailments in various preparations for example mixed with vinegar, in the 2nd century BC, Cato the Elder believed that cabbage could cure digestive diseases, ulcers, warts, and intoxication. Living about the turn of the millennium, Aulus Celsus, an ancient Roman doctor, believed in strong and weak foods

Disease
–
A disease is a particular abnormal condition, a disorder of a structure or function, that affects part or all of an organism. The study of disease is called pathology which includes the study of cause, Disease is often construed as a medical condition associated with specific symptoms and signs. When caused by pathogens, even in the literature, the term disease is often misleadingly used in the place of its causal agent. This language habitat can cause confusion in the communication of the principle in epidemiology. Diseases can affect not only physically, but also emotionally. Death due to disease is called death by natural causes, there are four main types of disease, infectious diseases, deficiency diseases, genetic diseases, and physiological diseases. Diseases can also be classified as communicable and non-communicable, the deadliest diseases in humans are coronary artery disease, followed by cerebrovascular disease and lower respiratory infections. In many cases, terms such as disease, disorder, morbidity, there are situations, however, when specific terms are considered preferable. Disease The term disease broadly refers to any condition that impairs the normal functioning of the body, for this reason, diseases are associated with dysfunctioning of the bodys normal homeostatic processes. The term disease has both a count sense and a noncount sense, by contrast, an infection that is asymptomatic during its incubation period, but expected to produce symptoms later, is usually considered a disease. Non-infectious diseases are all other diseases, including most forms of cancer, heart disease, acquired disease disease that began at some point during ones lifetime, as opposed to disease that was already present at birth, which is congenital disease. Acquired sounds like it could mean caught via contagion, but it simply means acquired sometime after birth and it also sounds like it could imply secondary disease, but acquired disease can be primary disease. It is often, genetic and can be inherited and it can also be the result of a vertically transmitted infection from the mother such as HIV/AIDS. Genetic disease disease that is caused by genetic mutation and it is often inherited, but some mutations are random and de novo. Hereditary or inherited disease a type of disease caused by mutation that is hereditary Iatrogenic disease A disease condition caused by medical intervention. Idiopathic disease disease whose cause is unknown, as medical science has advanced, many diseases whose causes were formerly complete mysteries have been somewhat explained or even extensively explained. Bacterial infections can be primary or secondary to a viral infection or burn. Terminal disease disease with death as an inevitable result Illness Illness is generally used as a synonym for disease, however, this term is occasionally used to refer specifically to the patients personal experience of his or her disease

Domestication
–
Charles Darwin recognized the small number of traits that made domestic species different from their wild ancestors. There is a difference between domestic and wild populations. The dog was the first domesticated vertebrate, and was established across Eurasia before the end of the Late Pleistocene era, well before cultivation and before the domestication of other animals. Among birds, the domestic species today is the chicken, important for meat and eggs, though economically valuable poultry include the turkey, guineafowl. Birds are also kept as cagebirds, from songbirds to parrots. The longest established invertebrate domesticates are the bee and the silkworm. Terrestrial snails are raised for food, while species from several phyla are kept for research, the domestication of plants began at least 12,000 years ago with cereals in the Middle East, and the bottle gourd in Asia. Agriculture developed in at least 11 different centres around the world, domesticating different crops, Domestication means belonging to the house. Animals domesticated for home companionship are usually called pets, while those domesticated for food or work are called livestock or farm animals and this definition recognizes both the biological and the cultural components of the domestication process and the impacts on both humans and the domesticated animals and plants. All past definitions of domestication have included a relationship between humans with plants and animals, but their differences lay in who was considered as the partner in the relationship. This new definition recognizes a mutualistic relationship in both partners gain benefits. Domestication has vastly enhanced the reproductive output of crop plants, livestock, Domestication syndrome is the suite of phenotypic traits arising during domestication that distinguish crops from their wild ancestors. The domestication of animals is the relationship between animals with the humans who have influence on their care and reproduction. Charles Darwin recognized the small number of traits that made domestic species different from their wild ancestors, there is a genetic difference between domestic and wild populations. Domestication should not be confused with taming, the beginnings of animal domestication involved a protracted coevolutionary process with multiple stages along different pathways. The dog was the first domesticant, and was established across Eurasia before the end of the Late Pleistocene era, well before cultivation and before the domestication of other animals. Humans did not intend to domesticate animals from, or at least they did not envision a domesticated animal resulting from, in both of these cases, humans became entangled with these species as the relationship between them, and the human role in their survival and reproduction, intensified. Although the directed pathway proceeded from capture to taming, the two pathways are not as goal-oriented and archaeological records suggest that they take place over much longer time frames

Environment (biophysical)
–
The biophysical environment can vary in scale from microscopic to global in extent. It can also be subdivided according to its attributes, examples include the marine environment, the atmospheric environment and the terrestrial environment. The number of environments is countless, given that each living organism has its own environment. The term environment is used as a short form for the biophysical environment. The expression the environment often refers to a global environment in relation to humanity. All life that has survived must have adapted to conditions of its environment, temperature, light, humidity, soil nutrients, etc. all influence any species, within any environment. However life in turn modifies, in forms, its conditions. Some long term modifications along the history of our planet have been significant and this process consisted in the breakdown of carbon dioxide by anaerobic microorganisms that used the carbon in their metabolism and released the oxygen to the atmosphere. This led to the existence of oxygen-based plant and animal life, other interactions are more immediate and simple, such as the smoothing effect that forests have on the temperature cycle, compared to neighboring unforested areas. Environmental science is the study of the interactions within the biophysical environment, part of this scientific discipline is the investigation of the effect of human activity on the environment. Ecology, a sub-discipline of biology and a part of environmental sciences, is mistaken as a study of human induced effects on the environment. Environmental studies is an academic discipline that is the systematic study of interaction of humans with their environment. It is a field of study that includes the natural environment, built environments. Environmentalism is a social and philosophical movement that, in a large part, seeks to minimise. The issues of concern for environmentalists usually relate to the environment with the more important ones being climate change, species extinction, pollution. One of the studies related include employing Geographic Information Science to study the biophysical environment, biophysics subject to the context List of conservation topics List of environmental issues Lists of environmental topics Miller, G. Tyler. McCallum, Malcolm L. Gwendolynn W. Bury, google search patterns suggest declining interest in the environment

Ethnic group
–
An ethnic group or ethnicity is a category of people who identify with each other based on similarities, such as common ancestral, language, social, cultural or national experiences. Unlike other social groups, ethnicity is often an inherited status based on the society in which one lives, in some cases, it can be adopted if a person moves into another society. Ethnic groups, derived from the historical founder population, often continue to speak related languages. By way of language shift, acculturation, adoption and religious conversion, it is possible for individuals or groups to leave one ethnic group. Ethnicity is often used synonymously with terms such as nation or people. In English, it can also have the connotation of something exotic, generally related to cultures of more recent immigrants, the largest ethnic groups in modern times comprise hundreds of millions of individuals, while the smallest are limited to a few dozen individuals. Conversely, formerly separate ethnicities can merge to form a pan-ethnicity, whether through division or amalgamation, the formation of a separate ethnic identity is referred to as ethnogenesis. The term ethnic is derived from the Greek word ἔθνος ethnos, the inherited English language term for this concept is folk, used alongside the latinate people since the late Middle English period. In Early Modern English and until the mid-19th century, ethnic was used to mean heathen or pagan, as the Septuagint used ta ethne to translate the Hebrew goyim the nations, non-Hebrews, non-Jews. The Greek term in antiquity could refer to any large group, a host of men. In the 19th century, the term came to be used in the sense of peculiar to a race, people or nation, the abstract ethnicity had been used for paganism in the 18th century, but now came to express the meaning of an ethnic character. The term ethnic group was first recorded in 1935 and entered the Oxford English Dictionary in 1972, depending on the context that is used, the term nationality may either be used synonymously with ethnicity, or synonymously with citizenship. The process that results in the emergence of an ethnicity is called ethnogenesis, the Greeks at this time did not describe foreign nations but had also developed a concept of their own ethnicity, which they grouped under the name of Hellenes. Herodotus gave an account of what defined Greek ethnic identity in his day, enumerating shared descent. Whether ethnicity qualifies as a universal is to some extent dependent on the exact definition used. Many social scientists, such as anthropologists Fredrik Barth and Eric Wolf and they regard ethnicity as a product of specific kinds of inter-group interactions, rather than an essential quality inherent to human groups. According to Thomas Hylland Eriksen, the study of ethnicity was dominated by two distinct debates until recently, one is between primordialism and instrumentalism. In the primordialist view, the participant perceives ethnic ties collectively, as a given, even coercive

Food processing
–
Food processing is the transformation of raw ingredients, by physical or chemical means into food, or of food into other forms. Food processing combines raw food ingredients to produce food products that can be easily prepared and served by the consumer. Salt-preservation was especially common for foods that constituted warrior and sailors diets until the introduction of canning methods and these tried and tested processing techniques remained essentially the same until the advent of the industrial revolution. Examples of ready-meals also date back to before the preindustrial revolution, both during ancient times and today in modern society these are considered processed foods. Modern food processing technology developed in the 19th and 20th centuries was developed in a part to serve military needs. Although initially expensive and somewhat hazardous due to the used in cans. Pasteurization, discovered by Louis Pasteur in 1864, improved the quality of preserved foods and introduced the wine, beer, in the late 20th century, products such as dried instant soups, reconstituted fruits and juices, and self cooking meals such as MRE food ration were developed. In western Europe and North America, the half of the 20th century witnessed a rise in the pursuit of convenience. Food processing companies marketed their products especially towards middle-class working wives, frozen foods found their success in sales of juice concentrates and TV dinners. Processors utilised the perceived value of time to appeal to the population. Benefits of food processing include toxin removal, preservation, easing marketing and distribution tasks, modern supermarkets would not exist without modern food processing techniques, and long voyages would not be possible. Processed foods are less susceptible to early spoilage than fresh foods and are better suited for long distance transportation from the source to the consumer. When they were first introduced, some processed foods helped to alleviate food shortages, processing can also reduce the incidence of food borne disease. Fresh materials, such as produce and raw meats, are more likely to harbour pathogenic micro-organisms capable of causing serious illnesses. The extremely varied modern diet is only possible on a wide scale because of food processing. Transportation of more exotic foods, as well as the elimination of much hard labour gives the modern eater easy access to a variety of food unimaginable to their ancestors. The act of processing can often improve the taste of food significantly, mass production of food is much cheaper overall than individual production of meals from raw ingredients. Therefore, a profit potential exists for the manufacturers and suppliers of processed food products

Landscape
–
A landscape is the visible features of an area of land, its landforms and how they integrate with natural or man-made features. The character of a landscape helps define the self-image of the people who inhabit it and it is the dynamic backdrop to people’s lives. Landscape can be as varied as farmland, a landscape park, the activity of modifying the visible features of an area of land is referred to as landscaping. There are several definitions of what constitutes a landscape, depending on context, the term landscape emerged around the turn of the sixteenth century to denote a painting whose primary subject matter was natural scenery. Land may be taken in its sense of something to people belong. The suffix ‑scape is equivalent to the more common English suffix ‑ship, the roots of ‑ship are etymologically akin to Old English sceppan or scyppan, meaning to shape. The suffix ‑schaft is related to the verb schaffen, so that ‑ship, the word landscape, first recorded in 1598, was borrowed from a Dutch painters term. An example of this usage can be found as early as 1662 in the Book of Common Prayer, Could we but climb where Moses stood. Setting, In works of narrative, it includes the moment in time and geographic location in which a story takes place. Picturesque, The word literally means in the manner of a picture, fit to be made into a picture, and used as early as 1703, gilpin’s Essay on Prints defined picturesque as a term expressive of that peculiar kind of beauty, which is agreeable in a picture. A view, A sight or prospect of some landscape or extended scene, wilderness, An uncultivated, uninhabited, and inhospitable region. Cityscape, The urban equivalent of a landscape, in the visual arts a cityscape is an artistic representation, such as a painting, drawing, print or photograph, of the physical aspects of a city or urban area. Seascape, A photograph, painting, or other work of art depicts the sea. Geomorphology is the study of the origin and evolution of topographic and bathymetric features created by physical or chemical processes operating at or near Earths surface. Geomorphology is practiced within physical geography, geology, geodesy, engineering geology, archaeology and this broad base of interests contributes to many research styles and interests within the field. The surface of Earth is modified by a combination of processes that sculpt landscapes, and geologic processes that cause tectonic uplift and subsidence. Many of these factors are strongly mediated by climate, the Earth surface and its topography therefore are an intersection of climatic, hydrologic, and biologic action with geologic processes.

Seasonality
–
In time series data, seasonality is the presence of variations that occur at specific regular intervals less than a year, such as weekly, monthly, or quarterly. Seasonal fluctuations in a series can be contrasted with cyclical patterns. The latter occur when the data exhibits rises and falls that are not of a fixed period and these fluctuations are usually due to economic conditions and are often related to the business cycle. The period of time usually extends beyond a year and the fluctuations are usually of at least two years. Organizations facing seasonal variations, such as vendors, are often interested in knowing their performance relative to the normal seasonal variation. It is necessary for organizations to identify and measure seasonal variations within their market to help plan for the future. This can prepare them for the temporary increases or decreases in labor requirements and this may require training, periodic maintenance, and so forth that can be organized in advance. There are several reasons for studying seasonal variation, The description of the seasonal effect provides a better understanding of the impact this component has upon a particular series. After establishing the pattern, methods can be implemented to eliminate it from the time-series to study the effect of other components such as cyclical. This elimination of the effect is referred to as de-seasonalizing or seasonal adjustment of data. To use the past patterns of the variations to contribute to forecasting. The run sequence plot is a recommended first step for analyzing any time series, although seasonality can sometimes be indicated by this plot, seasonality is shown more clearly by the seasonal subseries plot or the box plot. The seasonal subseries plot does an excellent job of showing both the differences and also the within-group patterns. The box plot shows the seasonal difference quite well, but it does not show within group patterns, however, for large data sets, the box plot is usually easier to read than the seasonal subseries plot. The seasonal plot, seasonal subseries plot, and the box plot all assume that the periods are known. In most cases, the analyst will in fact, know this, for example, for monthly data, the period is 12 since there are 12 months in a year. However, if the period is not known, the plot can help. If there is significant seasonality, the plot should show spikes at lags equal to the period

Technology
–
Technology is the collection of techniques, skills, methods and processes used in the production of goods or services or in the accomplishment of objectives, such as scientific investigation. Technology can be the knowledge of techniques, processes, and the like, the human species use of technology began with the conversion of natural resources into simple tools. The steady progress of technology has brought weapons of ever-increasing destructive power. It has helped develop more advanced economies and has allowed the rise of a leisure class, many technological processes produce unwanted by-products known as pollution and deplete natural resources to the detriment of Earths environment. Various implementations of technology influence the values of a society and raise new questions of the ethics of technology, examples include the rise of the notion of efficiency in terms of human productivity, and the challenges of bioethics. Philosophical debates have arisen over the use of technology, with disagreements over whether technology improves the condition or worsens it. The use of the technology has changed significantly over the last 200 years. Before the 20th century, the term was uncommon in English, the term was often connected to technical education, as in the Massachusetts Institute of Technology. The term technology rose to prominence in the 20th century in connection with the Second Industrial Revolution, the terms meanings changed in the early 20th century when American social scientists, beginning with Thorstein Veblen, translated ideas from the German concept of Technik into technology. In German and other European languages, a distinction exists between technik and technologie that is absent in English, which translates both terms as technology. By the 1930s, technology referred not only to the study of the industrial arts, dictionaries and scholars have offered a variety of definitions. Ursula Franklin, in her 1989 Real World of Technology lecture, gave another definition of the concept, it is practice, the way we do things around here. The term is used to imply a specific field of technology, or to refer to high technology or just consumer electronics. Bernard Stiegler, in Technics and Time,1, defines technology in two ways, as the pursuit of life by other than life, and as organized inorganic matter. Technology can be most broadly defined as the entities, both material and immaterial, created by the application of mental and physical effort in order to some value. In this usage, technology refers to tools and machines that may be used to solve real-world problems and it is a far-reaching term that may include simple tools, such as a crowbar or wooden spoon, or more complex machines, such as a space station or particle accelerator. Tools and machines need not be material, virtual technology, such as software and business methods. W. Brian Arthur defines technology in a broad way as a means to fulfill a human purpose

The mummies are buried in long barrows similar to the tomb mounds of western Scythian culture in modern Ukraine. The type site are the Pazyryk burials of the Ukok Plateau, the Pazyryk are considered to have had a war-like life. Other kurgan cemeteries associated with the culture include those of Bashadar, Tuekta, Ulandryk, Polosmak, there are so far no known sites of settlements associated with the burials, suggesting a purely nomadic lifestyle. At Pazyryk these included the bodies of horses and a man whose body was covered with tattoos of Scythian animal motifs. The remarkable textiles recovered from the Pazyryk burials include the oldest woollen knotted-pile carpet known, the oldest embroidered Chinese silk, red and ochre predominate in the carpet, the main design of which is of riders, stags, and griffins. Many of the Pazyryk felt hangings, saddlecloths, and cushions were covered with elaborate designs executed in appliqué feltwork, dyed furs, clothing, whether of felt, leather, or fur, was also lavishly ornamented. Horse reins either had animal designs cut out on them or were studded with wooden ones covered in gold foil and their tail sheaths were ornamented, as were their headpieces and breastpieces. Some horses were provided with leather or felt masks made to resemble animals, many of the trappings took the form of iron, bronze, and gilt wood animal motifs either applied or suspended from them, and bits had animal-shaped terminal ornaments. Altaic animals frequently display muscles delineated with dot and comma markings, although such markings are sometimes included in Assyrian, Achaemenian, and even Urartian animal representations of the ancient Middle East, they seldom appear on those of purely Scythian origin. Roundels containing a dot serve the purpose on the stag. Animal processions of the Assyro-Achaemenian type also appealed to many Central Asian tribesmen and are featured in their arts, certain geometric designs and sun symbols, such as the circle and rosette, recur at Pazyryk but are completely outnumbered by animal motifs. Such specifically Scythian features as zoomorphic junctures—i. e, the addition of a part of one animal to the body of another—are rarer in the Altaic region than in southern Russia. The stag and its relatives, however, figure as prominently in Altaic as in Scythian art, DNA samples recovered from the remains of two Pazyryk males showed them to be members of Y-chromosome haplogroup N1b-P43.

Pazyryk burials
–
Numerous comparable burials have been found in neighboring western Mongolia. The tombs are Scythian-type kurgans, barrow-like tomb mounds containing wooden chambers covered over by large cairns of boulders and stones, the spectacular burials at Pazyryk are responsible for the introduction of the term kurgan, a Russian word of Turkic origin, into general usage to describe these tombs. The region of the Pazyryk kurgans is considered the site of the wider Pazyryk culture. The site is included in the Golden Mountains of Altai UNESCO World Heritage Site, the bearers of the Pazyryk culture were horse-riding pastoral nomads of the steppe, and some may have accumulated great wealth through horse trading with merchants in Persia, India and China. These finds were preserved when water seeped into the tombs in antiquity and froze, encasing the burial goods in ice, certain geometric designs and sun symbols, such as the circle and rosette, recur at Pazyryk but are completely outnumbered by animal motifs. Such specifically Scythian features as zoomorphic junctures—i. e, the addition of a part of one animal to the body of another—are rarer in the Altaic region than in southern Russia. The stag and its relatives, however, figure as prominently in Altaic as in Scythian art, at Pazyryk too are found bearded mascarons of well-defined Greco-Roman origin, which were doubtless inspired by the Hellenistic kingdoms of the Cimmerian Bosporus. The first tomb at Pazyryk, barrow 1, was excavated by the archaeologist M. P. Gryaznov in 1929 and these finds are now exhibited at the Hermitage Museum in St. Petersburg. Craniological studies of samples from the Pazyryk burials determined that skulls were generally of Europoid type, rudenkos most striking discovery was the body of a tattooed Pazyryk chief, a thick-set, powerfully built man who had died when he was about 50. Parts of the body had deteriorated, but much of the tattooing was still clearly visible, subsequent investigation using reflected infrared photography revealed that all five bodies discovered in the Pazyryk kurgans were tattooed. No instruments specifically designed for tattooing were found, but the Pazyryks had extremely fine needles with which they did miniature embroidery, the chief was elaborately decorated with an interlocking series of striking designs representing a variety of fantastic beasts. The best preserved tattoos were images of a donkey, a mountain ram, two monsters resembling griffins decorate the chest, and on the left arm are three partially obliterated images which seem to represent two deer and a mountain goat. On the front of the leg a fish extends from the foot to the knee. A monster crawls over the foot, and on the inside of the shin is a series of four running rams which touch each other to form a single design. The left leg also bears tattoos, but these designs could not be clearly distinguished, in addition, the chiefs back is tattooed with a series of small circles in line with the vertebral column. This tattooing was probably done for therapeutic reasons, contemporary Siberian tribesmen still practice tattooing of this kind to relieve back pain. The most famous undisturbed Pazyryk burial so far recovered is the Ice Maiden or Altai Lady found by archaeologist Natalia Polosmak in 1993 at Ukok, near the Chinese border. The find was a example of a single woman given a full ceremonial burial in a wooden chamber tomb in the fifth century BC

Prehistory
–
Prehistory means literally before history, from the Latin word for before, præ, and Greek ιστορία. Neighbouring civilisations were the first to follow, most other civilisations reached the end of prehistory during the Iron Age. The period when a culture is written about by others, but has not developed its own writing is known as the protohistory of the culture. By definition, there are no records from human prehistory. Clear techniques for dating were not well-developed until the 19th century and this article is concerned with human prehistory as defined here above. There are separate articles for the history of the Earth. However, for the race as a whole, prehistory ends when recorded history begins with the accounts of the ancient world around the 4th millennium BC. For example, in Egypt it is accepted that prehistory ended around 3200 BC, whereas in New Guinea the end of the prehistoric era is set much more recently. The three-age system is the periodization of prehistory into three consecutive time periods, named for their respective predominant tool-making technologies, Stone Age Bronze Age Iron Age. The notion of prehistory began to surface during the Enlightenment in the work of antiquarians who used the word primitive to describe societies that existed before written records, the first use of the word prehistory in English, however, occurred in the Foreign Quarterly Review in 1836. The main source for prehistory is archaeology, but some scholars are beginning to more use of evidence from the natural and social sciences. This view has been articulated by advocates of deep history, human population geneticists and historical linguists are also providing valuable insight for these questions. Human prehistory differs from history not only in terms of its chronology, restricted to material processes, remains and artifacts rather than written records, prehistory is anonymous. Because of this, reference terms that use, such as Neanderthal or Iron Age are modern labels with definitions sometimes subject to debate. Palaeolithic means Old Stone Age, and begins with the first use of stone tools, the Paleolithic is the earliest period of the Stone Age. The early part of the Palaeolithic is called the Lower Palaeolithic, evidence of control of fire by early humans during the Lower Palaeolithic Era is uncertain and has at best limited scholarly support. The most widely accepted claim is that H. erectus or H. ergaster made fires between 790,000 and 690,000 BP in a site at Bnot Yaakov Bridge, Israel. The use of fire enabled early humans to cook food, provide warmth, Early Homo sapiens originated some 200,000 years ago, ushering in the Middle Palaeolithic

Cougar
–
The cougar, also commonly known as the mountain lion, puma, panther, or catamount, is a large felid of the subfamily Felinae native to the Americas. Its range, from the Canadian Yukon to the southern Andes of South America, is the greatest of any large wild terrestrial mammal in the Western Hemisphere, an adaptable, generalist species, the cougar is found in most American habitat types. It is the second-heaviest cat in the New World, after the jaguar, secretive and largely solitary by nature, the cougar is properly considered both nocturnal and crepuscular, although there are daytime sightings. The cougar is more related to smaller felines, including the domestic cat, than to any species of subfamily Pantherinae. The cougar is a predator and pursues a wide variety of prey. Primary food sources are ungulates, particularly deer, but also livestock and it also hunts species as small as insects and rodents. This cat prefers habitats with dense underbrush and rocky areas for stalking, the cougar is territorial and survives at low population densities. Individual territory sizes depend on terrain, vegetation, and abundance of prey, while large, it is not always the apex predator in its range, yielding to the jaguar, gray wolf, American black bear, and grizzly bear. It is reclusive and mostly avoids people, fatal attacks on humans are rare, but have recently been increasing in North America as more people enter their territories. Intensive hunting following European colonization of the Americas and the human development of cougar habitat has caused populations to drop in most parts of its historical range. In particular, the cougar was extirpated in eastern North America in the beginning of the 20th century, reports of eastern cougars still surface, although it was declared extirpated in 2011. With its vast range across the length of the Americas, P. concolor has dozens of names and various references in the mythology of the indigenous Americans and in contemporary culture. Currently, it is referred to as puma by most scientists, Mountain lion was a term first used in writing in 1858 from the diary of George A. Jackson of Colorado. Other names include catamount, mountain screamer, and painter, lexicographers regard painter as a primarily upper-Southern US regional variant on panther. The word panther is used to specifically designate the black panther, a melanistic jaguar or leopard, and the Florida panther. P. concolor holds the Guinness record for the animal with the greatest number of names, Cougar may be borrowed from the archaic Portuguese çuçuarana, the term was originally derived from the Tupi language susuarana, meaning similar to deer. A current form in Brazil is suçuarana and it may also be borrowed from the Guaraní language term guaçu ara or guazu ara. Less common Portuguese terms are onça-parda or leão-baio, or unusually non-native puma or leão-da-montanha, people in rural regions often refer to both the cougar and the jaguar as simply gata, and outside of the Amazon, both are colloquially referred to as simply onça by many people

Jaguar
–
The jaguar is a big cat, a feline in the Panthera genus, and is the only extant Panthera species native to the Americas. The jaguar is the third-largest feline after the tiger and the lion, the jaguars present range extends from Southwestern United States and Mexico across much of Central America and south to Paraguay and northern Argentina. Apart from a known and possibly breeding population in Arizona and the bootheel of New Mexico and this spotted cat most closely resembles the leopard physically, although it is usually larger and of sturdier build and its behavioral and habitat characteristics are closer to those of the tiger. While dense rainforest is its habitat, the jaguar will range across a variety of forested. Its preferred habitats are swamps and wooded regions, but jaguars also live in scrublands. The jaguar is notable, along with the tiger, as a feline that enjoys swimming, the jaguar is largely a solitary, opportunistic, stalk-and-ambush predator at the top of the food chain. It is a species, playing an important role in stabilizing ecosystems. The jaguar has a powerful bite, even relative to the other big cats. This allows it to pierce the shells of armored reptiles and to employ an unusual killing method, the jaguar is a near threatened species and its numbers are declining. Threats include loss and fragmentation of habitat, while international trade in jaguars or their parts is prohibited, the cat is still frequently killed by humans, particularly in conflicts with ranchers and farmers in South America. Although reduced, its range remains large, given its historical distribution, the jaguar has featured prominently in the mythology of numerous indigenous American cultures, including those of the Maya and Aztec. The word jaguar comes to English from one of the Tupi–Guarani languages, presumably the Amazonian trade language Tupinambá, the Tupian word, yaguara beast, is sometimes translated as dog. The specific word for jaguar is yaguareté, with the suffix -eté meaning real or true, the first component of its taxonomic designation, Panthera, is Latin, from the Greek word for leopard, πάνθηρ, the type species for the genus. Onca is the Portuguese onça, with the cedilla dropped for reasons, found in English as ounce for the snow leopard. It derives from the Latin lyncea lynx, with the letter L confused with the definite article, the jaguar, Panthera onca, is the only extant New World member of the genus Panthera.8 million years ago. Phylogenetic studies generally have shown the clouded leopard is basal to this group, the position of the remaining species varies between studies and is effectively unresolved. Based on morphological evidence, British zoologist Reginald Pocock concluded the jaguar is most closely related to the leopard, however, DNA evidence is inconclusive and the position of the jaguar relative to the other species varies between studies. Fossils of extinct Panthera species, such as the European jaguar, analysis of jaguar mitochondrial DNA has dated the species lineage to between 280,000 and 510,000 years ago, later than suggested by fossil records
35.
Mesolithic
–
In archaeology, the Mesolithic is the culture between Paleolithic and Neolithic. The term Epipaleolithic is often used for areas outside northern Europe, Mesolithic has different time spans in different parts of Eurasia. It was originally post-Pleistocene, pre-agricultural material in northwest Europe about 10,000 to 5000 BC, in the archaeology of Northern Europe, for example for archaeological sites in Great Britain, Germany, Scandinavia, Ukraine, and Russia, the term Mesolithic is almost always used. In the archaeology of other areas, the term Epipaleolithic may be preferred by most authors, in the New World, neither term is used. Other authors use the term Mesolithic for a variety of Late Paleolithic cultures subsequent to the end of the last glacial period whether they are transitional towards agriculture or not, conversely, those that are in course of transition toward artificial food production are assigned to the Mesolithic. Therefore, care must be taken in translating Mesolithic as Middle Stone Age, subdivisions of earlier and later were added to the Stone Age by Thomsen and especially his junior colleague and employee Jens Jacob Asmussen Worsaae. John Lubbock kept these divisions in his work Pre-historic Times in 1865 and he saw no need for an intermediate category. When Hodder Westropp introduced the Mesolithic in 1866, as an intermediate between Paleolithic and Neolithic, a storm of controversy immediately arose around it. A British school led by John Evans denied any need for an intermediate, the ages blended together like the colors of a rainbow, he said. A European school led by Louis Laurent Gabriel de Mortillet asserted that there was a gap between the earlier and later, edouard Piette claimed to have filled the gap with his discovery of the Azilian Culture. Knut Stjerna offered an alternative in the Epipaleolithic, a continuation of the use of Paleolithic technology, the start and end dates of the Mesolithic vary by geographical region. Childes view prevails that the term covers the period between the end of the Pleistocene and the start of the Neolithic. If the Mesolithic is more similar to the Paleolithic it is called the Epipaleolithic, the Paleolithic was an age of purely hunting and gathering while in the Neolithic domestication of plants and animals had occurred. Some Mesolithic peoples continued with intensive hunting, others were practising the initial stages of domestication. The type of remains the diagnostic factor, The Mesolithic featured composite devices manufactured with Mode V chipped stone tools. The Paleolithic had utilized Modes I–IV and the Neolithic mainly abandoned the chipped microliths in favor of polished, not chipped, the first period, known as Mesolithic 1, followed the Aurignacian or Levantine Upper Paleolithic periods throughout the Levant. By the end of the Aurignacian, gradual changes took place in stone industries, small stone tools called microliths and retouched bladelets can be found for the first time. The microliths of this period differ greatly from the Aurignacian artifacts

Lake Baikal
–
Lake Baikal is a rift lake in Russia, located in southern Siberia, between Irkutsk Oblast to the northwest and the Buryat Republic to the southeast. Lake Baikal is the largest freshwater lake by volume in the world, with 23,615.39 km3 of fresh water, it contains more water than the North American Great Lakes combined. With a maximum depth of 1,642 m, Baikal is the worlds deepest lake and it is considered among the worlds clearest lakes and is considered the worlds oldest lake — at 25 million years. It is the seventh-largest lake in the world by surface area, like Lake Tanganyika, Lake Baikal was formed as an ancient rift valley, having the typical long crescent shape with a surface area of 31,722 km2. Baikal is home to thousands of species of plants and animals, the lake was declared a UNESCO World Heritage Site in 1996. The region to the east of Lake Baikal is referred to as Transbaikalia, Lake Baikal is in a rift valley, created by the Baikal Rift Zone, where the Earths crust is slowly pulling apart. At 636 km long and 79 km wide, Lake Baikal has the largest surface area of any lake in Asia, at 31,722 km2. The bottom of the lake is 1,186.5 m below sea level, but below this lies some 7 km of sediment, placing the rift floor some 8–11 km below the surface, the deepest continental rift on Earth. In geological terms, the rift is young and active—it widens about 2 cm per year, the fault zone is also seismically active, hot springs occur in the area and notable earthquakes happen every few years. The lake is divided into three basins, North, Central, and South, with depths about 900 m,1,600 m, fault-controlled accommodation zones rising to depths about 300 m separate the basins. The North and Central basins are separated by Academician Ridge, while the area around the Selenga Delta, the lake drains into the Angara tributary of the Yenisei. Notable landforms include Cape Ryty on Baikals northwest coast, Baikals age is estimated at 25 million years, making it the most ancient lake in geological history. It is unique among large, high-latitude lakes, as its sediments have not been scoured by overriding continental ice sheets. Russian, U. S. and Japanese cooperative studies of deep-drilling core sediments in the 1990s provide a record of climatic variation over the past 6.7 million years. Longer and deeper sediment cores are expected in the near future, Lake Baikal is the only confined freshwater lake in which direct and indirect evidence of gas hydrates exists. The lake is surrounded by mountains. The Baikal Mountains on the shore and the taiga are technically protected as a national park. It contains 27 islands, the largest, Olkhon, is 72 km long and is the third-largest lake-bound island in the world, the lake is fed by as many as 330 inflowing rivers

Ukok Plateau
–
Ukok Plateau is a remote and pristine grasslands area located in the heart of southwestern Siberia, the Altai Mountains region of Russia near the borders with China, Kazakhstan and Mongolia. The plateau is recognized as part of the UNESCO World Heritage Site entitled Golden Mountains of Altai as an important environmental treasure and it provides a habitat for many of the worlds endangered species including one of its least studied predatory animals, the snow leopard. Other endangered species protected there include the mountain sheep, the steppe eagle. Currently the Ukok Plateau is being threatened by plans for a gas pipeline between China and Russia and it is also being threatened by a proposal to build a road through it as well as overuse of the steppe by ranchers. The Mongolian word uheg - literally means elongated cabinet, box, according to the oral testimony of S. Umurzakova Ukok in Kyrgyz used to refer to flat-topped mountains, ie plateaus. The Ukok Plateau is the plain located between South-Altai and Sailugem and ridges at a height of 2, 200–2,500 m above sea level. There are 500–600 m high mountain peaks that tower above the plateau, the highest peak on the plateau is the mountain knot of Tavan-Bogdo-Ula where the highest mountain is Khüiten Peak that reaches 4,374 m above sea level. This is the second highest peak in Siberia after Belukha Mountain, the present-day eastern Altai-Sayan region areas of Ukok-Sailiugem could be considered the closest analogy to the ancient mammoth steppe environment. Many ancient Bronze Age tomb mounds have been found in the area and have associated with the Pazyryk culture which closely resembled that of the legendary Scythian people to the west. The term kurgen is in usage to describe such log-barrow burials. Excavations of this site have continued to yield notable archaeological finds, one famous finding is known as the Ice Maiden, excavated by Russian archaeologist Natalia Polosmak. The Ice Maiden and other finds were located just within a disputed strip of land between Russia and China. The residents of the Altai Republic are demanding the return of the artifacts from their current location in Novosibirsk. The Ukok plateau is linked to the world by heavy-going dirt roads through the Ukok, Ulan-Daba, Teplyi kluch. The Teplyi kluch pass is at an altitude of 2,907 m, one may get to these passes from Kosh-Agach village, which is easily reachable owing to a relatively improved M52 highway. Southward, beyond Kosh-Agach, the way becomes impassable for common means of transport, however, even they could become stuck in swamp mud in the Kalguty river valley, especially after a sunny day when frozen soil begins thawing. For most of the year the passes are snow-covered and avalanche-prone, during the short summer season all the slopes are prone to solifluction. S. I.

PubMed Identifier
–
PubMed is a free search engine accessing primarily the MEDLINE database of references and abstracts on life sciences and biomedical topics. The United States National Library of Medicine at the National Institutes of Health maintains the database as part of the Entrez system of information retrieval, from 1971 to 1997, MEDLINE online access to the MEDLARS Online computerized database primarily had been through institutional facilities, such as university libraries. PubMed, first released in January 1996, ushered in the era of private, free, home-, the PubMed system was offered free to the public in June 1997, when MEDLINE searches via the Web were demonstrated, in a ceremony, by Vice President Al Gore. Information about the journals indexed in MEDLINE, and available through PubMed, is found in the NLM Catalog. As of 5 January 2017, PubMed has more than 26.8 million records going back to 1966, selectively to the year 1865, and very selectively to 1809, about 500,000 new records are added each year. As of the date,13.1 million of PubMeds records are listed with their abstracts. In 2016, NLM changed the system so that publishers will be able to directly correct typos. Simple searches on PubMed can be carried out by entering key aspects of a subject into PubMeds search window, when a journal article is indexed, numerous article parameters are extracted and stored as structured information. Such parameters are, Article Type, Secondary identifiers, Language, publication type parameter enables many special features. As these clinical girish can generate small sets of robust studies with considerable precision, since July 2005, the MEDLINE article indexing process extracts important identifiers from the article abstract and puts those in a field called Secondary Identifier. The secondary identifier field is to store numbers to various databases of molecular sequence data, gene expression or chemical compounds. For clinical trials, PubMed extracts trial IDs for the two largest trial registries, ClinicalTrials. gov and the International Standard Randomized Controlled Trial Number Register, a reference which is judged particularly relevant can be marked and related articles can be identified. If relevant, several studies can be selected and related articles to all of them can be generated using the Find related data option, the related articles are then listed in order of relatedness. To create these lists of related articles, PubMed compares words from the title and abstract of each citation, as well as the MeSH headings assigned, using a powerful word-weighted algorithm. The related articles function has been judged to be so precise that some researchers suggest it can be used instead of a full search, a strong feature of PubMed is its ability to automatically link to MeSH terms and subheadings. Examples would be, bad breath links to halitosis, heart attack to myocardial infarction, where appropriate, these MeSH terms are automatically expanded, that is, include more specific terms. Terms like nursing are automatically linked to Nursing or Nursing and this important feature makes PubMed searches automatically more sensitive and avoids false-negative hits by compensating for the diversity of medical terminology. The My NCBI area can be accessed from any computer with web-access, an earlier version of My NCBI was called PubMed Cubby

Melittology is a branch of entomology concerning the scientific study of bees. Melittology covers the species found in the clade Anthophila within the superfamily Apoidea, comprising more than 20,000 species, including bumblebees, apiology – is the scientific study of honey bees. Honey bees are often chosen as a group to answer questions on the evolution of social systems. Apidology is a variant spelling of apiology used outside of the Western Hemisphere, primarily in Europe, apicology – the study of honey bee ecology. Melittologists and apiologists are served by a number of scientific societies, charles Butler, early English beekeeper and researcher.

Arachnology
–
Arachnology is the scientific study of spiders and related animals such as scorpions, pseudoscorpions, and harvestmen, collectively called arachnids. Those who study spiders and other arachnids are arachnologists, the word arachnology derives from Greek ἀράχνη, arachnē, spider, and -λογία, -logia. Arachnologists are primarily responsible for classifying arachnids and studying aspects of their biology, in the popular imagination they are sometimes referred to as spider experts. Other arachnologists perform research on the anatomy or physiology of arachnids, including the venom of spiders, others study the impact of spiders in agricultural ecosystems and whether they can be used as biological control agents. Arachnology can be broken down into more specific specialties and these topics include, acarology - the study of ticks and mites. Araneology - the study of spiders, scorpiology - the study of scorpions. Arachnologists are served by a number of societies, both national and international in scope. Their main role is to encourage the exchange of ideas between researchers, to meetings and congresses, and in a number of cases to publish academic journals. Some are also involved in outreach programs, like the European spider of the year. Many tarantulas thus become more known by their common names such as the Mexican redknee tarantula. Various societies now focus on the husbandry, care, study and captive breeding of tarantulas and they also typically produce journals or newsletters with articles and advice on these subjects

Batrachology is the branch of zoology concerned with the study of amphibians including frogs and toads, salamanders, newts, and caecilians. It is a sub-discipline of herpetology, which includes also non-avian reptiles, batrachologists may study the evolution, ecology, ethology, or anatomy of amphibians. There are over 7250 species of amphibians, jean Marius René Guibé Gabriel Bibron Oskar Boettger George Albert Boulenger Edward Drinker Cope François Marie Daudin Franz Werner

Biological anthropology
–
It is a subfield of anthropology that provides a biological perspective to the systematic study of human beings. As a subfield of anthropology, biological anthropology itself is divided into several branches. All branches are united in their application of evolutionary theory to understanding human morphology. Primatology, the study of primate behavior, morphology. Reasons via homology and analogy to infer how and why similar human traits evolved, human behavioral ecology, the study of behavioral adaptations from the evolutionary and ecologic perspectives. Human adaptation, the study of human responses to environmental stresses. Bioarchaeology, the study of past human cultures through examination of human remains recovered in an archaeological context, the examined human remains usually comprises bones, but may include preserved soft tissue. Researchers in bioarchaeology combine the skillsets of human osteology, paleopathology, and archaeology, paleopathology is the study of disease in antiquity. Scientific physical anthropology began in the 18th century with the study of racial classification, the first prominent physical anthropologist, the German physician Johann Friedrich Blumenbach of Göttingen, amassed a large collection of human skulls. In 1897 Columbia University appointed Franz Boas as a physical anthropologist for his expertise in measuring schoolchildren, from his German education and training, Boas emphasized the mutability of the human form and minimized race in favor of culture. Ales Hrdlicka, a physician, studied anthropology in France under Leonce Manouvrier before working at the Smithsonian Institution from 1902. Earnest Hooton, a Classics PhD from the University of Wisconsin, entered anthropology as an Oxford Rhodes Scholar under R. R. Marett, there was much intellectual continuity with Germans such as Eugen Fischer, Fritz Lenz and Erwin Baur. In 1951 Sherwood Washburn, a Hooton alumnus, introduced a new physical anthropology and he changed the focus from racial typology to concentrate upon the study of human evolution, moving away from classification towards evolutionary process. Anthropology expanded to comprehend paleoanthropology and primatology, in contrast to much of medical anthropology, it does not generally take a critical approach to biomedicine and Western medicine. Instead, it seeks to improve medical practice and biomedical science through the integration of cross-cultural or biocultural, behavioral. As an academic discipline, biomedical anthropology is closely related to human biology, currently, the only accredited degree program in biomedical anthropology is at Binghamton University. Other anthropology departments, such as that of the University of Washington, anthropometry, the measurement of the human individual Craniometry Ethology Evolutionary biology Evolutionary psychology Paleontology Physiognomy Primatology Sociobiology Michael A

Cetology
–
Cetology or Whalelore is the branch of marine mammal science that studies the approximately eighty species of whales, dolphins, and porpoise in the scientific order Cetacea. Cetologists, or those who practice cetology, seek to understand and explain cetacean evolution, distribution, morphology, behavior, community dynamics, observations about Cetacea have been recorded since at least classical times. Ancient Greek fishermen created an artificial notch on the fin of dolphins entangled in nets so that they could tell them apart years later. Approximately 2,300 years ago, Aristotle carefully took notes on cetaceans while traveling on boats with fishermen in the Aegean Sea, in his book Historia animalium, Aristotle was careful enough to distinguish between the baleen whales and toothed whales, a taxonomical separation still used today. He also described the Sperm Whale and the dolphin, stating that they can live for at least twenty-five or thirty years. His achievement was remarkable for its time, because today it is very difficult to estimate the life-span of advanced marine animals. After Aristotles death, much of the knowledge he had gained about cetaceans was lost, many of the medieval texts on cetaceans come mainly from Scandinavia and Iceland, most came about the mid-13th century. One of the better known is Speculum Regale, in this text is described various species that lived around the island of Iceland. It mentions orcs that had teeth and would demonstrate the same kind of aggression towards other cetaceans as wild dogs would to other terrestrial animals. The text even illustrated the hunting technique of Orcs, which are now called Orcas, the Speculum Regale describes other cetaceans, including the Sperm Whale and Narwhal. Many times they were seen as monsters, such as killers of men. They even bore odd names such as Pig Whale, Horse Whale, but not all creatures described were said to be fierce. Some were seen to be good, such as whales that drove shoals of herring towards the shore and this was seen as very helpful to fisherman. Many of the studies were based on dead specimens and myth. The little information that was gathered was usually length, and an outer body anatomy. Because these animals live in water their entire lives, early scientists did not have the technology to go study these animals further and it was not until the 16th century that things would begin to change. Then cetaceans would be proved to be rather than fish. But Pliny the Elder stated that they were fish, and it was followed by many naturalists, however, Pierre Belon and G. Rondelet persisted on convincing they were mammals

Coleopterology
–
Coleopterology is a branch of entomology, the scientific study of beetles of the order Coleoptera). Coleopterists have formed organizations to facilitate the study of beetles, among these is The Coleopterists Society, an international organization based in the United States. Such organizations may have both professionals and amateurs as members, interested in beetles, when speaking informally, coleopterists sometimes refer to their study as beetling. Some of the specific to beetle research are, The Coleopterist The Coleopterists Bulletin Coléoptères Elytron J. Cooter & M. V. L. Barclay. The beetles of the German Reich, a. Horion, ed. faunistics the Central European beetles. H. Joy, KW Harde, GA Lohse, eds, the beetles of Central Europe Goecke & Evers, Krefeld. KW Harde, F.

Conchology
–
Conchology is the study of mollusc shells. Conchology is one aspect of malacology, the study of molluscs, however, malacology is the study of molluscs as whole organisms and it includes the study of land and freshwater mollusc shells as well as seashells and extends to the study of a gastropods operculum. Conchology is now seen as an archaic study, because relying on only one aspect of an organisms morphology can be misleading. However, a shell often gives at least some insight into molluscan taxonomy, even in current museum collections it is common for the dry material to greatly exceed the amount of material that is preserved whole in alcohol. Conchologists mainly deal with four orders, the gastropods, bivalves, Polyplacophora. Cephalopods only have internal shells, with the exception of the Nautiloidea. Some groups, such as the sea slug nudibranchs, have lost their shells altogether, the terms shell collector and conchologist can be regarded as two distinct categories. Not all shell collectors are conchologists, some are concerned with the aesthetic value of shells instead of their scientific study. It is also true that not all conchologists are shell collectors, there is some debate in the conchological community, with some people regarding all shell collectors as conchologists. Molluscs have probably been used by primates as a food long before humans evolved. Shell collecting, the precursor of conchology, probably goes back as far as there have been living near beaches. Stone Age seashell necklaces have been found, sometimes in areas far from the ocean, Shell jewellery is found at almost all archaeological sites, including at ancient Aztec ruins, digs in ancient China, and the Indus Valley. During the Renaissance people began taking interest in objects of beauty to put in cabinets of curiosities. Because of their attractiveness, variety, durability and ubiquity, shells became a part of these collections. Towards the end of the 17th century, people looking at shells with scientific interest. Martin Lister in 1685–1692 published Historia Conchyliorum, which was the first comprehensive conchological text, george Rumpf, or Rumphius, published the first mollusc taxonomy. He suggested single shelled ones, snails or whelks, and two-shelled ones, many of Rumpfs terms were adopted by Carl Linnaeus. Rumpf continued to do important scientific work after he went blind, the study of zoology, including conchology, was revolutionized by Swedish naturalist Carl Linnaeus and his system of binomial nomenclature
