Conservation status
–
The conservation status of a group of organisms indicates whether the group still exists and how likely the group is to become extinct in the near future. Various systems of conservation status exist and are in use at international, multi-country, the IUCN Red List of Threatened Species is the best known worldwide conservation status listing and ranking system. Also included are species that have gone extinct since 500 AD, when discussing the IUCN Red List, the official term threatened is a grouping of three categories, critically endangered, endangered, and vulnerable. Widespread and abundant taxa are included in this category, Data deficient – Not enough data to make an assessment of its risk of extinction Not evaluated – Has not yet been evaluated against the criteria. The Convention on International Trade in Endangered Species of Wild Fauna and Flora aims to ensure that trade in specimens of wild animals. Many countries require CITES permits when importing plants and animals listed on CITES, in the European Union, the Birds and Habitats Directives are the legal instruments that evaluate the conservation status within the EU of species and habitats. NatureServe conservation status focuses on Latin America, United States, Canada, and it has been developed by scientists from NatureServe, The Nature Conservancy, and the network of natural heritage programs and data centers. It is increasingly integrated with the IUCN Red List system and its categories for species include, presumed extinct, possibly extinct, critically imperiled, imperiled, vulnerable, apparently secure, and secure. The system also allows ambiguous or uncertain ranks including inexact numeric ranks, NatureServe adds a qualifier for captive or cultivated only, which has a similar meaning to the IUCN Red List extinct in the wild status. The Red Data Book of the Russian Federation is used within the Russian Federation, in Australia, the Environment Protection and Biodiversity Conservation Act 1999 describes lists of threatened species, ecological communities and threatening processes. The categories resemble those of the 1994 IUCN Red List Categories & Criteria, prior to the EPBC Act, a simpler classification system was used by the Endangered Species Protection Act 1992. Some state and territory governments also have their own systems for conservation status, in Belgium, the Flemish Research Institute for Nature and Forest publishes an online set of more than 150 nature indicators in Dutch. In Canada, the Committee on the Status of Endangered Wildlife in Canada is a group of experts that assesses and designates which wild species are in danger of disappearing from Canada. Under the Species at Risk Act, it is up to the federal government, in China, the State, provinces and some counties have determined their key protected wildlife species. There is the China red data book, in Finland, a large number of species are protected under the Nature Conservation Act, and through the EU Habitats Directive and EU Birds Directive. In Germany, the Federal Agency for Nature Conservation publishes red lists of endangered species, india has the Wild Life Protection Act,1972, Amended 2003 and the Biological Diversity Act,2002. In Japan, the Ministry of Environment publishes a Threatened Wildlife of Japan Red Data Book, in the Netherlands, the Dutch Ministry of Agriculture, Nature and Food Quality publishes a list of threatened species, and conservation is enforced by the Nature Conservation Act 1998. Species are also protected through the Wild Birds and Habitats Directives, in New Zealand, the Department of Conservation publishes the New Zealand Threat Classification System lists

Near Threatened
–
The IUCN notes the importance of re-evaluating near-threatened taxa at appropriate intervals. The rationale used for near-threatened taxa usually includes the criteria of vulnerable which are plausible or nearly met, additionally, the 402 conservation-dependent taxa may also be considered near-threatened. Prior to 2001, the IUCN used the version 2.3 Categories and Criteria, with this category system, Near Threatened and Conservation Dependent were both subcategories of the category Lower Risk. IUCN Red List near threatened species, ordered by taxonomic rank, category, IUCN Red List near threatened species, ordered alphabetically

IUCN Red List
–
The IUCN Red List of Threatened Species, founded in 1964, is the worlds most comprehensive inventory of the global conservation status of biological species. The International Union for Conservation of Nature is the main authority on the conservation status of species. A series of Regional Red Lists are produced by countries or organizations, the IUCN Red List is set upon precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world, the aim is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to try to reduce species extinction. Major species assessors include BirdLife International, the Institute of Zoology, the World Conservation Monitoring Centre, collectively, assessments by these organizations and groups account for nearly half the species on the Red List. The IUCN aims to have the category of every species re-evaluated every five years if possible, the 1964 IUCN Red List of Threatened Plants used the older pre-criteria Red List assessment system. Plants listed may not, therefore, appear in the current Red List, IUCN advise that is best to check both the online Red List and the 1997 plants Red List publication. The 2006 Red List, released on 4 May 2006 evaluated 40,168 species as a whole, plus an additional 2,160 subspecies, varieties, aquatic stocks, on 12 September 2007, the World Conservation Union released the 2007 IUCN Red List of Threatened Species. Russ Mittermeier, chief of Swiss-based IUCNs Primate Specialist Group, stated that 16,306 species are endangered with extinction,188 more than in 2006, the Red List includes the Sumatran orangutan in the Critically Endangered category and the Bornean orangutan in the Endangered category. The study shows at least 1,141 of the 5,487 mammals on Earth are known to be threatened with extinction, and 836 are listed as Data Deficient. The Red List of 2012 was released 19 July 2012 at Rio+20 Earth Summit, nearly 2,000 species were added, the IUCN assessed a total of 63,837 species which revealed 19,817 are threatened with extinction. With 3,947 described as endangered and 5,766 as endangered. At threat are 41% of amphibian species, 33% of reef-building corals, 30% of conifers, 25% of mammals, the IUCN Red List has listed 132 species of plants and animals from India as Critically Endangered. Extinct – No known individuals remaining, extinct in the wild – Known only to survive in captivity, or as a naturalized population outside its historic range. Critically endangered – Extremely high risk of extinction in the wild, Endangered – High risk of extinction in the wild. Vulnerable – High risk of endangerment in the wild, near threatened – Likely to become endangered in the near future. Does not qualify for a more at-risk category, widespread and abundant taxa are included in this category. Data deficient – Not enough data to make an assessment of its risk of extinction, Not evaluated – Has not yet been evaluated against the criteria

Taxonomy (biology)
–
Taxonomy is the science of defining groups of biological organisms on the basis of shared characteristics and giving names to those groups. The exact definition of taxonomy varies from source to source, but the core of the remains, the conception, naming. There is some disagreement as to whether biological nomenclature is considered a part of taxonomy, the broadest meaning of taxonomy is used here. The word taxonomy was introduced in 1813 by Candolle, in his Théorie élémentaire de la botanique, the term alpha taxonomy is primarily used today to refer to the discipline of finding, describing, and naming taxa, particularly species. In earlier literature, the term had a different meaning, referring to morphological taxonomy, ideals can, it may be said, never be completely realized. They have, however, a value of acting as permanent stimulants. Some of us please ourselves by thinking we are now groping in a beta taxonomy, turrill thus explicitly excludes from alpha taxonomy various areas of study that he includes within taxonomy as a whole, such as ecology, physiology, genetics, and cytology. He further excludes phylogenetic reconstruction from alpha taxonomy, thus, Ernst Mayr in 1968 defined beta taxonomy as the classification of ranks higher than species. This activity is what the term denotes, it is also referred to as beta taxonomy. How species should be defined in a group of organisms gives rise to practical and theoretical problems that are referred to as the species problem. The scientific work of deciding how to define species has been called microtaxonomy, by extension, macrotaxonomy is the study of groups at higher taxonomic ranks, from subgenus and above only, than species. While some descriptions of taxonomic history attempt to date taxonomy to ancient civilizations, earlier works were primarily descriptive, and focused on plants that were useful in agriculture or medicine. There are a number of stages in scientific thinking. Early taxonomy was based on criteria, the so-called artificial systems. Later came systems based on a complete consideration of the characteristics of taxa, referred to as natural systems, such as those of de Jussieu, de Candolle and Bentham. The publication of Charles Darwins Origin of Species led to new ways of thinking about classification based on evolutionary relationships and this was the concept of phyletic systems, from 1883 onwards. This approach was typified by those of Eichler and Engler, the advent of molecular genetics and statistical methodology allowed the creation of the modern era of phylogenetic systems based on cladistics, rather than morphology alone. Taxonomy has been called the worlds oldest profession, and naming and classifying our surroundings has likely been taking place as long as mankind has been able to communicate

Animal
–
Animals are multicellular, eukaryotic organisms of the kingdom Animalia. The animal kingdom emerged as a clade within Apoikozoa as the group to the choanoflagellates. Animals are motile, meaning they can move spontaneously and independently at some point in their lives and their body plan eventually becomes fixed as they develop, although some undergo a process of metamorphosis later in their lives. All animals are heterotrophs, they must ingest other organisms or their products for sustenance, most known animal phyla appeared in the fossil record as marine species during the Cambrian explosion, about 542 million years ago. Animals can be divided broadly into vertebrates and invertebrates, vertebrates have a backbone or spine, and amount to less than five percent of all described animal species. They include fish, amphibians, reptiles, birds and mammals, the remaining animals are the invertebrates, which lack a backbone. These include molluscs, arthropods, annelids, nematodes, flatworms, cnidarians, ctenophores, the study of animals is called zoology. The word animal comes from the Latin animalis, meaning having breath, the biological definition of the word refers to all members of the kingdom Animalia, encompassing creatures as diverse as sponges, jellyfish, insects, and humans. Aristotle divided the world between animals and plants, and this was followed by Carl Linnaeus, in the first hierarchical classification. In Linnaeuss original scheme, the animals were one of three kingdoms, divided into the classes of Vermes, Insecta, Pisces, Amphibia, Aves, and Mammalia. Since then the last four have all been subsumed into a single phylum, in 1874, Ernst Haeckel divided the animal kingdom into two subkingdoms, Metazoa and Protozoa. The protozoa were later moved to the kingdom Protista, leaving only the metazoa, thus Metazoa is now considered a synonym of Animalia. Animals have several characteristics that set apart from other living things. Animals are eukaryotic and multicellular, which separates them from bacteria and they are heterotrophic, generally digesting food in an internal chamber, which separates them from plants and algae. They are also distinguished from plants, algae, and fungi by lacking cell walls. All animals are motile, if only at life stages. In most animals, embryos pass through a stage, which is a characteristic exclusive to animals. With a few exceptions, most notably the sponges and Placozoa and these include muscles, which are able to contract and control locomotion, and nerve tissues, which send and process signals
6.
Chordate
–
Chordates are deuterostomes, as during the embryo development stage the anus forms before the mouth. They are also bilaterally symmetric coelomates, in the case of vertebrate chordates, the notochord is usually replaced by a vertebral column during development, and they may have body plans organized via segmentation. There are also additional extinct taxa, the Vertebrata are sometimes considered as a subgroup of the clade Craniata, consisting of chordates with a skull, the Craniata and Tunicata compose the clade Olfactores. Of the more than 65,000 living species of chordates, the worlds largest and fastest animals, the blue whale and peregrine falcon respectively, are chordates, as are humans. Fossil chordates are known from at least as early as the Cambrian explosion, Hemichordata, which includes the acorn worms, has been presented as a fourth chordate subphylum, but it now is usually treated as a separate phylum. The Hemichordata, along with the Echinodermata, form the Ambulacraria, the Chordata and Ambulacraria form the superphylum Deuterostomia, composed of the deuterostomes. Attempts to work out the relationships of the chordates have produced several hypotheses. All of the earliest chordate fossils have found in the Early Cambrian Chengjiang fauna. Because the fossil record of early chordates is poor, only molecular phylogenetics offers a prospect of dating their emergence. However, the use of molecular phylogenetics for dating evolutionary transitions is controversial and it has also proved difficult to produce a detailed classification within the living chordates. Attempts to produce family trees shows that many of the traditional classes are paraphyletic. While this has been known since the 19th century, an insistence on only monophyletic taxa has resulted in vertebrate classification being in a state of flux. Although the name Chordata is attributed to William Bateson, it was already in prevalent use by 1880, ernst Haeckel described a taxon comprising tunicates, cephalochordates, and vertebrates in 1866. Though he used the German vernacular form, it is allowed under the ICZN code because of its subsequent latinization, among the vertebrate sub-group of chordates the notochord develops into the spine, and in wholly aquatic species this helps the animal to swim by flexing its tail. In fish and other vertebrates, this develops into the spinal cord, the pharynx is the part of the throat immediately behind the mouth. In fish, the slits are modified to form gills, a muscular tail that extends backwards behind the anus. This is a groove in the wall of the pharynx. In filter-feeding species it produces mucus to gather food particles, which helps in transporting food to the esophagus and it also stores iodine, and may be a precursor of the vertebrate thyroid gland

Bird
–
Birds, a subgroup of Reptiles, are the last living examples of Dinosaurs. Birds live worldwide and range in size from the 5 cm bee hummingbird to the 2.75 m ostrich. They rank as the class of tetrapods with the most living species, at ten thousand. Birds are the closest living relatives of crocodilians, the fossil record indicates that birds evolved from feathered ancestors within the theropod group of saurischian dinosaurs. True birds first appeared during the Cretaceous period, around 100 million years ago, Birds, especially those in the southern continents, survived this event and then migrated to other parts of the world while diversifying during periods of global cooling. Primitive bird-like dinosaurs that lie outside class Aves proper, in the broader group Avialae, have been found dating back to the mid-Jurassic period, around 170 million years ago. Birds have wings which are more or less developed depending on the species, the digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have evolved for swimming. Many species annually migrate great distances, Birds are social, communicating with visual signals, calls, and bird songs, and participating in such social behaviours as cooperative breeding and hunting, flocking, and mobbing of predators. The vast majority of species are socially monogamous, usually for one breeding season at a time, sometimes for years. Other species have breeding systems that are polygynous or, rarely, Birds produce offspring by laying eggs which are fertilised through sexual reproduction. They are usually laid in a nest and incubated by the parents, most birds have an extended period of parental care after hatching. Some birds, such as hens, lay eggs even when not fertilised, songbirds, parrots, and other species are popular as pets. Guano is harvested for use as a fertiliser, Birds prominently figure throughout human culture. About 120–130 species have become extinct due to human activity since the 17th century, human activity threatens about 1,200 bird species with extinction, though efforts are underway to protect them. Recreational birdwatching is an important part of the ecotourism industry, the first classification of birds was developed by Francis Willughby and John Ray in their 1676 volume Ornithologiae. Carl Linnaeus modified that work in 1758 to devise the taxonomic classification system currently in use, Birds are categorised as the biological class Aves in Linnaean taxonomy. Phylogenetic taxonomy places Aves in the dinosaur clade Theropoda, Aves and a sister group, the clade Crocodilia, contain the only living representatives of the reptile clade Archosauria

Parrot
–
Parrots, also known as psittacines /ˈsɪtəsaɪnz/, are birds of the roughly 393 species in 92 genera that make up the order Psittaciformes, found in most tropical and subtropical regions. The order is subdivided into three superfamilies, the Psittacoidea, the Cacatuoidea, and the Strigopoidea, Parrots have a generally pantropical distribution with several species inhabiting temperate regions in the Southern Hemisphere, as well. The greatest diversity of parrots is in South America and Australasia, characteristic features of parrots include a strong, curved bill, an upright stance, strong legs, and clawed zygodactyl feet. Many parrots are vividly coloured, and some are multi-coloured, most parrots exhibit little or no sexual dimorphism in the visual spectrum. They form the most variably sized bird order in terms of length, the most important components of most parrots diets are seeds, nuts, fruit, buds, and other plant material. A few species sometimes eat animals and carrion, while the lories and lorikeets are specialised for feeding on floral nectar, almost all parrots nest in tree hollows, and lay white eggs from which hatch altricial young. Parrots, along with ravens, crows, jays, and magpies, are among the most intelligent birds, some parrots are intelligent and talk at the level of a four-to-five year old human. Measures taken to conserve the habitats of some high-profile charismatic species have protected many of the less charismatic species living in the same ecosystems. Psittaciform diversity in South America and Australasia suggests that the order may have evolved in Gondwana, molecular studies suggest that parrots evolved approximately 59 million years ago in Gondwana. The three major clades of Neotropical parrots originated about 50 Mya, likewise, the earliest parrots do not have the specialised crushing bills of modern species. If so, they probably had not evolved their morphological autapomorphies yet, the combined evidence supported the hypothesis of Psittaciformes being near passerines, i. e. the mostly land-living birds that emerged in close proximity to the K-Pg extinction. Europe is the origin of the first undeniable parrot fossils, which date from about 50 Mya, the climate there and then was tropical, consistent with the Paleocene-Eocene thermal maximum. Initially, a neoavian named Mopsitta tanta, uncovered in Denmarks Early Eocene Fur Formation and dated to 54 Mya, was assigned to the Psittaciformes, fossils assignable to Psittaciformes date from slightly later in the Eocene, starting around 50 Mya. Several fairly complete skeletons of birds have been found in England. The fossil record—mainly from Europe—consists of bones clearly recognisable as belonging to parrots of modern type, at this point, however, is found the first unambiguous parrot fossil, an upper jaw that is indistinguishable from that of modern cockatoos. The Psittaciformes comprise three lineages, Strigopoidea, Psittacoidea and Cacatuoidea. Colourful feathers with high levels of psittacofulvin resist the feather-degrading bacterium Bacillus licheniformis better than white ones, lorikeets were previously regarded as a third family, Loriidae, but are now considered a tribe within the subfamily Lorinae, family Cacatuoidea. The two other tribes in the subfamily are the closely related fig parrots and budgerigar, the order Psittaciformes consists of roughly 393 species belonging to 92 genera

Psittacidae
–
The family Psittacidae is one of three families of true parrots. It comprises the approximately 10 species of subfamily Psittacinae and 148 species of subfamily Arinae, some of the most iconic birds in the world are represented here, such as the blue-and-gold macaw among the New World parrots and the African grey parrot among the Old World parrots. Two parrots, one extinct, formerly inhabited North America and it is estimated that the New World parrots, and by implication Old World parrots, last shared a common ancestor with the Australian parrots of Cacatuidae c.59 mya. The data place most of the diversification of psittaciforms around 40 mya, after the separation of Australia from West Antarctica, the family Psittacidae was introduced by the French polymath Constantine Samuel Rafinesque in 1815. Subfamily Loriinae and the tribes of subfamily Psittacinae are now placed in superfamily Psittacoidea of all true parrots which includes family Psittacidae

Psittacula
–
Members of the parrot genus Psittacula or Afro-Asian ringnecked parakeets as they are commonly known in aviculture originates found from Africa to South-East Asia. It is a group, with a clear concentration of species in south Asia, but also with representatives in Africa. This is the genus of Parrot which has majority of its species in continental Asia. Of all the extant species only Psittacula calthropae, Psittacula caniceps, the rose-ringed parakeet, Psittacula krameri, is one of the most widely distributed of all parrots. The other two Asian genera, Loriculus and Psittinus are represented by two and one species respectively, which occur in the mainland part of Asia. The majority of the Loriculus species occur on islands, moreover, since Loriculus is spread across both sides of the Wallace Line it can be considered more Australasian than Asian. These parrots are mostly green plumaged, with adults having coloured heads, the bill is stout, and the tail is long and graduated. The genus name Psittacula is a diminutive of Latin psittacus, parrot, intermedia, found in northern India, was considered something of a mystery, as only very few specimens were known. It has finally been demonstrated to be a hybrid between the slaty-headed parakeet P. himalayana and the plum-headed parakeet P. cyanocephala, the Réunion parakeet P. eques, taxonomy is also confusing. Extinct since 1770, little evidence exists of the birds existence. A study skin had been discovered at the Royal Museum of Scotland and it is known from other descriptions, as well as illustrations of which it is unknown whether they were drawn from live or stuffed specimens. This may be the only proof of these birds existence. Taxonomists are unsure if the birds were a species, or conspecific with the Mauritius parakeet.

Binomial nomenclature
–
Such a name is called a binomial name, a binomen, binominal name or a scientific name, more informally it is also called a Latin name. The first part of the name identifies the genus to which the species belongs, for example, humans belong to the genus Homo and within this genus to the species Homo sapiens. The formal introduction of system of naming species is credited to Carl Linnaeus. But Gaspard Bauhin, in as early as 1623, had introduced in his book Pinax theatri botanici many names of genera that were adopted by Linnaeus. Although the general principles underlying binomial nomenclature are common to these two codes, there are differences, both in the terminology they use and in their precise rules. Similarly, both parts are italicized when a binomial name occurs in normal text, thus the binomial name of the annual phlox is now written as Phlox drummondii. In scientific works, the authority for a name is usually given, at least when it is first mentioned. In zoology Patella vulgata Linnaeus,1758, the original name given by Linnaeus was Fringilla domestica, the parentheses indicate that the species is now considered to belong in a different genus. The ICZN does not require that the name of the person who changed the genus be given, nor the date on which the change was made, in botany Amaranthus retroflexus L. – L. is the standard abbreviation used in botany for Linnaeus. – Linnaeus first named this bluebell species Scilla italica, Rothmaler transferred it to the genus Hyacinthoides, the ICN does not require that the dates of either publication be specified. Prior to the adoption of the binomial system of naming species. Together they formed a system of polynomial nomenclature and these names had two separate functions. First, to designate or label the species, and second, to be a diagnosis or description, such polynomial names may sometimes look like binomials, but are significantly different. For example, Gerards herbal describes various kinds of spiderwort, The first is called Phalangium ramosum, Branched Spiderwort, is aptly termed Phalangium Ephemerum Virginianum, Soon-Fading Spiderwort of Virginia. The Latin phrases are short descriptions, rather than identifying labels, the Bauhins, in particular Caspar Bauhin, took some important steps towards the binomial system, by pruning the Latin descriptions, in many cases to two words. The adoption by biologists of a system of binomial nomenclature is due to Swedish botanist and physician Carl von Linné. It was in his 1753 Species Plantarum that he first began using a one-word trivial name together with a generic name in a system of binomial nomenclature. This trivial name is what is now known as an epithet or specific name
12.
Carl Linnaeus
–
Carl Linnaeus, also known after his ennoblement as Carl von Linné, was a Swedish botanist, physician, and zoologist, who formalised the modern system of naming organisms called binomial nomenclature. He is known by the father of modern taxonomy. Many of his writings were in Latin, and his name is rendered in Latin as Carolus Linnæus, Linnaeus was born in the countryside of Småland, in southern Sweden. He received most of his education at Uppsala University. He lived abroad between 1735 and 1738, where he studied and also published a first edition of his Systema Naturae in the Netherlands and he then returned to Sweden, where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on journeys through Sweden to find and classify plants. In the 1750s and 1760s, he continued to collect and classify animals, plants, and minerals, at the time of his death, he was one of the most acclaimed scientists in Europe. The philosopher Jean-Jacques Rousseau sent him the message, Tell him I know no man on earth. The German writer Johann Wolfgang von Goethe wrote, With the exception of Shakespeare and Spinoza, Swedish author August Strindberg wrote, Linnaeus was in reality a poet who happened to become a naturalist. Among other compliments, Linnaeus has been called Princeps botanicorum, The Pliny of the North and he is also considered as one of the founders of modern ecology. In botany, the abbreviation used to indicate Linnaeus as the authority for species names is L. In older publications, sometimes the abbreviation Linn. is found, Linnæus was born in the village of Råshult in Småland, Sweden, on 23 May 1707. He was the first child of Nicolaus Ingemarsson and Christina Brodersonia and his siblings were Anna Maria Linnæa, Sofia Juliana Linnæa, Samuel Linnæus, and Emerentia Linnæa. One of a line of peasants and priests, Nils was an amateur botanist, a Lutheran minister. Christina was the daughter of the rector of Stenbrohult, Samuel Brodersonius, a year after Linnæus birth, his grandfather Samuel Brodersonius died, and his father Nils became the rector of Stenbrohult. The family moved into the rectory from the curates house, even in his early years, Linnæus seemed to have a liking for plants, flowers in particular. Whenever he was upset, he was given a flower, which calmed him. Nils spent much time in his garden and often showed flowers to Linnaeus, soon Linnæus was given his own patch of earth where he could grow plants
13.
Genus
–
A genus is a taxonomic rank used in the biological classification of living and fossil organisms in biology. In the hierarchy of classification, genus comes above species. In binomial nomenclature, the name forms the first part of the binomial species name for each species within the genus. Felis catus and Felis silvestris are two species within the genus Felis, Felis is a genus within the family Felidae. The composition of a genus is determined by a taxonomist, the standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. Moreover, genera should be composed of units of the same kind as other genera. The term comes from the Latin genus, a noun form cognate with gignere, linnaeus popularized its use in his 1753 Species Plantarum, but the French botanist Joseph Pitton de Tournefort is considered the founder of the modern concept of genera. The scientific name of a genus may be called the name or generic epithet. It plays a role in binomial nomenclature, the system of naming organisms. The rules for the names of organisms are laid down in the Nomenclature Codes. The standard way of scientifically describing species and other lower-ranked taxa is by binomial nomenclature, the generic name forms its first half. For example, the gray wolfs binomial name is Canis lupus, with Canis being the name shared by the wolfs close relatives. The specific name is written in lower-case and may be followed by names in zoology or a variety of infraspecific names in botany. Especially with these names, when the generic name is known from context. Because animals are typically only grouped within subspecies, it is written as a trinomen with a third name. Dog breeds, meanwhile, are not scientifically distinguished, there are several divisions of plant species and therefore their infraspecific names generally include contractions explaining the relation. For example, the genus Hibiscus includes hundreds of other species apart from the Rose of Sharon or common garden hibiscus, Rose of Sharon doesnt have subspecies but has cultivars that carry desired traits, such as the bright white H. syriaca Diana. Hawaiian hibiscus, meanwhile, includes several separate species, since not all botanists agree on the divisions or names between species, it is common to specify the source of the name using author abbreviations
14.
Family (biology)
–
In biological classification, family is one of the eight major taxonomic ranks, it is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks above the rank of genus. In vernacular usage, a family may be named one of its common members, for example, walnuts and hickory trees belong to the family Juglandaceae. What does or does not belong to a family—or whether a family should be recognized at all—are proposed and determined by practicing taxonomists. There are no rules for describing or recognizing a family. Taxonomists often take different positions about descriptions of taxa, and there may be no broad consensus across the community for some time. Some described taxa are accepted broadly and quickly, but others only rarely, if at all, the naming of families is codified by various international codes. In zoological nomenclature, the names of animals end with the suffix -idae. The concept of rank at time was not yet settled, and in the preface to the Prodromus Magnol spoke of uniting his families into larger genera. Carolus Linnaeus used the word familia in his Philosophia botanica to denote groups of plants, trees, herbs, ferns, palms. He used this term only in the section of the book. In zoology, the family as an intermediate between order and genus was introduced by Pierre André Latreille in his Précis des caractères génériques des insectes. He used families in some but not in all his orders of insects, families can be used for evolutionary, palaeontological and generic studies because they are more stable than lower taxonomic levels such as genera and species

Alexander the Great
–
Alexander III of Macedon, commonly known as Alexander the Great, was a king of the Ancient Greek kingdom of Macedon and a member of the Argead dynasty. He was born in Pella in 356 BC and succeeded his father Philip II to the throne at the age of twenty and he was undefeated in battle and is widely considered one of historys most successful military commanders. During his youth, Alexander was tutored by Aristotle until the age of 16, after Philips assassination in 336 BC, he succeeded his father to the throne and inherited a strong kingdom and an experienced army. Alexander was awarded the generalship of Greece and used this authority to launch his fathers Panhellenic project to lead the Greeks in the conquest of Persia, in 334 BC, he invaded the Achaemenid Empire and began a series of campaigns that lasted ten years. Following the conquest of Anatolia, Alexander broke the power of Persia in a series of battles, most notably the battles of Issus. He subsequently overthrew Persian King Darius III and conquered the Achaemenid Empire in its entirety, at that point, his empire stretched from the Adriatic Sea to the Indus River. He sought to reach the ends of the world and the Great Outer Sea and invaded India in 326 BC and he eventually turned back at the demand of his homesick troops. Alexander died in Babylon in 323 BC, the city that he planned to establish as his capital, without executing a series of planned campaigns that would have begun with an invasion of Arabia. In the years following his death, a series of civil wars tore his empire apart, resulting in the establishment of several states ruled by the Diadochi, Alexanders surviving generals, Alexanders legacy includes the cultural diffusion which his conquests engendered, such as Greco-Buddhism. He founded some twenty cities that bore his name, most notably Alexandria in Egypt, Alexander became legendary as a classical hero in the mold of Achilles, and he features prominently in the history and mythic traditions of both Greek and non-Greek cultures. He became the measure against which military leaders compared themselves, and he is often ranked among the most influential people in human history. He was the son of the king of Macedon, Philip II, and his wife, Olympias. Although Philip had seven or eight wives, Olympias was his wife for some time. Several legends surround Alexanders birth and childhood, sometime after the wedding, Philip is said to have seen himself, in a dream, securing his wifes womb with a seal engraved with a lions image. Plutarch offered a variety of interpretations of dreams, that Olympias was pregnant before her marriage, indicated by the sealing of her womb. On the day Alexander was born, Philip was preparing a siege on the city of Potidea on the peninsula of Chalcidice. That same day, Philip received news that his general Parmenion had defeated the combined Illyrian and Paeonian armies, and it was also said that on this day, the Temple of Artemis in Ephesus, one of the Seven Wonders of the World, burnt down. This led Hegesias of Magnesia to say that it had burnt down because Artemis was away, such legends may have emerged when Alexander was king, and possibly at his own instigation, to show that he was superhuman and destined for greatness from conception

Punjab
–
The Punjab, also spelled Panjab, panj-āb, land of five rivers, is a geographical and cultural region in the northern part of South Asia, comprising areas of eastern Pakistan and northern India. Not being a unit, the extent of the region is the subject of debate. The foreign invaders mainly targeted the most productive region of the Punjab known as the Majha region. The people of the Punjab today are called Punjabis and their language is called Punjabi. The main religions of the Punjab region are Islam, Sikhism and Hinduism, other religious groups are Christianity, Jainism and Buddhism. The name of the region is a compound of two Persian words Panj and āb and was introduced to the region by the Turko-Persian conquerors of India, Punjab literally means Five Waters referring to the rivers, Jhelum, Chenab, Ravi, Sutlej, and Beas. All are tributaries of the Indus River, the Chenab being the largest, there are two main definitions of the Punjab region, the 1947 definition and the older 1846–1849 definition. The third definition incorporates both the 1947 and the definitions but also includes northern Rajasthan on a linguistic basis. 1947 definition The 1947 definition defines the Punjab region with reference to the dissolution of British India whereby the then British Punjab Province was partitioned between India and Pakistan, in Pakistan, the region now includes the Punjab province and Islamabad Capital Territory. In India, it includes the Punjab state, Chandigarh, Haryana, Using the 1947 definition, the Punjab region borders Kashmir to the north, Sindh and Rajasthan to the south, the Pashtun region and Balochistan to the west, and the Hindi belt to the east. Accordingly, the Punjab region is diverse and stretches from the hills of the Kangra Valley to the plains. Present day maps Major cities Using the 1947 definition of the Punjab region, some of the cities of the area include Lahore, Faisalabad. Older 1846–1849 definition The older definition of the Punjab region focuses on the collapse of the Sikh Empire, According to this definition, the Punjab region incorporates, in Pakistan, Azad Kashmir including Bhimber and Mirpur and parts of Khyber Pakhtunkhwa. In India the wider definition includes parts of Delhi and Jammu Division, the formation of the Himalayan Range of mountains to the east and north-east of the Punjab is the result of a collision between the north-moving Indo-Australian Plate and the Eurasian Plate. The plates are moving together, and the Himalayas are rising by about 5 millimetres per year. The upper regions are snow-covered the whole year, Lower ranges of hills run parallel to the mountains. The Lower Himalayan Range runs from north of Rawalpindi through Jammu and Kashmir, Himachal Pradesh, the mountains are relatively young, and are eroding rapidly. The Indus and the five rivers of the Punjab have their sources in the range and carry loam, minerals and silt down to the rich alluvial plains

Europe
–
Europe is a continent that comprises the westernmost part of Eurasia. Europe is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, yet the non-oceanic borders of Europe—a concept dating back to classical antiquity—are arbitrary. Europe covers about 10,180,000 square kilometres, or 2% of the Earths surface, politically, Europe is divided into about fifty sovereign states of which the Russian Federation is the largest and most populous, spanning 39% of the continent and comprising 15% of its population. Europe had a population of about 740 million as of 2015. Further from the sea, seasonal differences are more noticeable than close to the coast, Europe, in particular ancient Greece, was the birthplace of Western civilization. The fall of the Western Roman Empire, during the period, marked the end of ancient history. Renaissance humanism, exploration, art, and science led to the modern era, from the Age of Discovery onwards, Europe played a predominant role in global affairs. Between the 16th and 20th centuries, European powers controlled at times the Americas, most of Africa, Oceania. The Industrial Revolution, which began in Great Britain at the end of the 18th century, gave rise to economic, cultural, and social change in Western Europe. During the Cold War, Europe was divided along the Iron Curtain between NATO in the west and the Warsaw Pact in the east, until the revolutions of 1989 and fall of the Berlin Wall. In 1955, the Council of Europe was formed following a speech by Sir Winston Churchill and it includes all states except for Belarus, Kazakhstan and Vatican City. Further European integration by some states led to the formation of the European Union, the EU originated in Western Europe but has been expanding eastward since the fall of the Soviet Union in 1991. The European Anthem is Ode to Joy and states celebrate peace, in classical Greek mythology, Europa is the name of either a Phoenician princess or of a queen of Crete. The name contains the elements εὐρύς, wide, broad and ὤψ eye, broad has been an epithet of Earth herself in the reconstructed Proto-Indo-European religion and the poetry devoted to it. For the second part also the divine attributes of grey-eyed Athena or ox-eyed Hera. The same naming motive according to cartographic convention appears in Greek Ανατολή, Martin Litchfield West stated that phonologically, the match between Europas name and any form of the Semitic word is very poor. Next to these there is also a Proto-Indo-European root *h1regʷos, meaning darkness. Most major world languages use words derived from Eurṓpē or Europa to refer to the continent, in some Turkic languages the originally Persian name Frangistan is used casually in referring to much of Europe, besides official names such as Avrupa or Evropa

Mediterranean Sea
–
The sea is sometimes considered a part of the Atlantic Ocean, although it is usually identified as a separate body of water. The name Mediterranean is derived from the Latin mediterraneus, meaning inland or in the middle of land and it covers an approximate area of 2.5 million km2, but its connection to the Atlantic is only 14 km wide. The Strait of Gibraltar is a strait that connects the Atlantic Ocean to the Mediterranean Sea and separates Gibraltar. In oceanography, it is called the Eurafrican Mediterranean Sea or the European Mediterranean Sea to distinguish it from mediterranean seas elsewhere. The Mediterranean Sea has a depth of 1,500 m. The sea is bordered on the north by Europe, the east by Asia and it is located between latitudes 30° and 46° N and longitudes 6° W and 36° E. Its west-east length, from the Strait of Gibraltar to the Gulf of Iskenderun, the seas average north-south length, from Croatia’s southern shore to Libya, is approximately 800 km. The Mediterranean Sea, including the Sea of Marmara, has an area of approximately 2,510,000 square km. The sea was an important route for merchants and travelers of ancient times that allowed for trade, the history of the Mediterranean region is crucial to understanding the origins and development of many modern societies. In addition, the Gaza Strip and the British Overseas Territories of Gibraltar and Akrotiri, the term Mediterranean derives from the Latin word mediterraneus, meaning amid the earth or between land, as it is between the continents of Africa, Asia and Europe. The Ancient Greek name Mesogeios, is similarly from μέσο, between + γη, land, earth) and it can be compared with the Ancient Greek name Mesopotamia, meaning between rivers. The Mediterranean Sea has historically had several names, for example, the Carthaginians called it the Syrian Sea and latter Romans commonly called it Mare Nostrum, and occasionally Mare Internum. Another name was the Sea of the Philistines, from the people inhabiting a large portion of its shores near the Israelites, the sea is also called the Great Sea in the General Prologue by Geoffrey Chaucer. In Ottoman Turkish, it has also been called Bahr-i Sefid, in Modern Hebrew, it has been called HaYam HaTikhon, the Middle Sea, reflecting the Seas name in ancient Greek, Latin, and modern languages in both Europe and the Middle East. Similarly, in Modern Arabic, it is known as al-Baḥr al-Mutawassiṭ, in Turkish, it is known as Akdeniz, the White Sea since among Turks the white colour represents the west. Several ancient civilisations were located around the Mediterranean shores, and were influenced by their proximity to the sea. It provided routes for trade, colonisation, and war, as well as food for numerous communities throughout the ages, due to the shared climate, geology, and access to the sea, cultures centered on the Mediterranean tended to have some extent of intertwined culture and history. Two of the most notable Mediterranean civilisations in classical antiquity were the Greek city states, later, when Augustus founded the Roman Empire, the Romans referred to the Mediterranean as Mare Nostrum

Royal family
–
A royal family is the immediate family of a king or queen regnant, and sometimes his or her extended family. However, in common parlance members of any family which reigns by hereditary right are often referred to as royalty or royals and it is also customary in some circles to refer to the extended relations of a deposed monarch and his or her descendants as a royal family. A dynasty is referred to as the House of. As of July 2013, there are 26 active sovereign monarchies in the world who rule or reign over 43 countries in all, in some cases, royal family membership may extend to great grandchildren and more distant descendants of a monarch. In certain monarchies where voluntary abdication is the norm, such as the Netherlands, there is often a distinction between persons of the blood royal and those that marry into the royal family. In certain instances, such as in Canada, the family is defined by who holds the styles Majesty. Under most systems, only persons in the first category are dynasts and this is not always observed, some monarchies have operated by the principle of jure uxoris. In addition, certain relatives of the monarch possess special privileges and are subject to certain statutes, conventions, the precise functions of a royal family vary depending on whether the polity in question is an absolute monarchy, a constitutional monarchy, or somewhere in between. The specific composition of royal families varies from country to country, as do the titles and royal, the composition of the royal family may be regulated by statute enacted by the legislature, the sovereigns prerogative and common law tradition, or a private house law. Public statutes, constitutional provisions, or conventions may also regulate the marriages, names, the members of a royal family may or may not have a surname or dynastic name. Some countries have abolished royalty altogether, as in post-revolutionary France, whilst mediatization occurred in other countries such as France, Italy and Russia, only the certain houses within the former Holy Roman Empire are collectively called the Mediatized Houses

Nobility
–
The privileges associated with nobility may constitute substantial advantages over or relative to non-nobles, or may be largely honorary, and vary from country to country and era to era. There is often a variety of ranks within the noble class. g, san Marino and the Vatican City in Europe. Hereditary titles often distinguish nobles from non-nobles, although in many nations most of the nobility have been un-titled, some countries have had non-hereditary nobility, such as the Empire of Brazil. The term derives from Latin nobilitas, the noun of the adjective nobilis. In modern usage, nobility is applied to the highest social class in pre-modern societies and it rapidly came to be seen as a hereditary caste, sometimes associated with a right to bear a hereditary title and, for example in pre-revolutionary France, enjoying fiscal and other privileges. Nobility is a historical, social and often legal notion, differing from high socio-economic status in that the latter is based on income. Being wealthy or influential cannot, ipso facto, make one noble, various republics, including former Iron Curtain countries, Greece, Mexico, and Austria have expressly abolished the conferral and use of titles of nobility for their citizens. Not all of the benefits of nobility derived from noble status per se, usually privileges were granted or recognised by the monarch in association with possession of a specific title, office or estate. Most nobles wealth derived from one or more estates, large or small and it also included infrastructure such as castle, well and mill to which local peasants were allowed some access, although often at a price. Nobles were expected to live nobly, that is, from the proceeds of these possessions, work involving manual labour or subordination to those of lower rank was either forbidden or frowned upon socially. In some countries, the lord could impose restrictions on such a commoners movements. Nobles exclusively enjoyed the privilege of hunting, in France, nobles were exempt from paying the taille, the major direct tax. In some parts of Europe the right of war long remained the privilege of every noble. During the early Renaissance, duelling established the status of a respectable gentleman, Nobility came to be associated with social rather than legal privilege, expressed in a general expectation of deference from those of lower rank. By the 21st century even that deference had become increasingly minimised, in France, a seigneurie might include one or more manors surrounded by land and villages subject to a nobles prerogatives and disposition. Seigneuries could be bought, sold or mortgaged, if erected by the crown into, e. g. a barony or countship, it became legally entailed for a specific family, which could use it as their title. Yet most French nobles were untitled, in other parts of Europe, sovereign rulers arrogated to themselves the exclusive prerogative to act as fons honorum within their realms. Nobility might be inherited or conferred by a fons honorum
21.
Warlord
–
A warlord is a leader able to exercise military, economic, and political control over a subnational territory within a sovereign state due to his ability to mobilize loyal armed forces. These armed forces, usually considered militias, are loyal to the rather than to the state regime. Warlords have existed throughout much of history, albeit in a variety of different capacities within the political, economic, and social structure of states or ungoverned territories. The first non-English usage of warlord appeared in Germany in 1861, with the translation as Kriegsherr, there is also a divergence of opinion within the field of political science as to what specifically constitutes warlordism, particularly in the context of the historical setting. There are two major functional distinctions when considering warlords vis-à-vis their relationship with the state and this can be viewed as cooperative warlord politics. The other is one in which the warlord is operating independently of the state and is viewed as a rebel and this is commonly viewed as ungoverned warlordism. The other major consideration in categorizing warlords is through the lens of history, Warlordism was a widespread, dominant political framework that ordered many of the worlds societies until the modern state became globally ubiquitous. Often warlord governance in pre-modern state history was constructed along tribal or kinship lines and was congruent with early perceptions of nation, in colonial empires warlords served in both cooperative political capacities and as leaders of rebellions. In modern states the presence of warlords is often seen as an indicator of state weakness or failure, American historian David G. Herrmann noted, Warlordism is the default condition of humanity. In both cases there is an inherent inefficiency in the model, as resources are wasted on unproductive arming and fighting, however, the functionality is often sustainable because it presents citizens with no choice but to accept rent payments in exchange for protection. Charles Tilly, an American political scientist and sociologist, theorized that organized crime can function as a means for war and he argues that the monopoly of crime by the state--in this case being the warlords--is in order to receive protection from external rivals as well as internal political rivals. As noted French philosopher Alexis de Tocqueville and political scientists such as E. J, within political science there is a growing body of research and analysis on warlordism that has emerged within weak states that have gained independence as a result of the collapse of empire. Warlord states are disproportionately concentrated within two regions--the former European colonies of Africa and the former Soviet republics of Eurasia, the warlords, with their established militias, are able to maintain a monopoly of violence within certain territories. By limiting access to these privileges, members of the dominant warlord coalition create credible incentives to cooperate rather than fight among themselves, Driscoll termed this warlordism Militia Coalition Politics. As Driscoll observed, the warlords colluded to create a state, one political theory, pioneered by American economist Mancur Olson, posits that warlords can function as stationary bandits. In some African states warlord politics can be a product of endowment-rich, some nations, including Liberia and Sierra Leone, have had stationary bandits who use extraction of resources such as diamonds, cobalt and timber in order to increase their political power. They often enforce their right to resources by claiming to be protecting the people. These warlords, or stationary bandits, often partner with compliant foreign firms and create symbiotic relationships to yield greater power for the warlords and a source of wealth for external firms

Feral animal
–
A feral animal is an animal living in the wild but descended from domesticated individuals. As with a species, the introduction of feral animals or plants to non-native regions may disrupt ecosystems and has, in some cases. Other definitions define a feral animal as one that has changed from being domesticated to being wild, natural, some common examples of animals with feral populations are horses, dogs, goats, cats, and pigs. Wild species naturalized into a new territory are not normally considered feral animals, domesticated plants that revert to wild are referred to as escaped, introduced, naturalized, or sometimes as feral crops. Individual plants are known as volunteers, large numbers of escaped plants may become a noxious weed. The adaptive and ecological variables seen in plants that go wild closely resemble those of animals, the unintended presence of genetically modified crop plants or of the modified traits in other plants as a result of cross-breeding is known as adventitious presence. Certain familiar animals go feral easily and successfully, while others are less inclined to wander. Some species will detach readily from humans and pursue their own devices, others depart and are gone, seeking out new territory or range to exploit and displaying active invasiveness. Whether they leave readily and venture far, the criterion for success is longevity. Persistence depends on their ability to establish themselves and reproduce reliably in the new environment, neither the duration nor the intensity with which a species has been domesticated offers a useful correlation with its feral potential. The cat returns readily to a state if it has not been socialized when young. These cats, especially if left to proliferate, are considered to be pests in both rural and urban areas, and may be blamed for devastating the bird, reptile. A local population of cats living in an urban area. As feral cats multiply quickly, it is difficult to control their populations, animal shelters attempt to adopt out feral cats, especially kittens, but often are overwhelmed with sheer numbers and euthanasia is used. In rural areas, excessive numbers of cats are often shot. More recently, the method has been used in many locations as an alternate means of managing the feral cat population. The dog has some difficulty reverting into a feral state, not as efficient in predation like their wolf ancestors or even their big cat rivals, The goat is one of the oldest domesticated creatures, yet readily goes feral and does quite well on its own. The dromedary camel, which has been domesticated for well over 3,000 years, a substantial population of feral dromedaries, descended from pack animals that escaped in the 19th and early 20th centuries, thrives in the Australian interior today

Population
–
A population is the number of all the organisms of the same group or species, which live in a particular geographical area, and have the capability of interbreeding. In sociology, population refers to a collection of humans, Demography is a social science which entails the statistical study of human populations. This article refers mainly to human population, in population genetics a sexual population is a set of organisms in which any pair of members can breed together. This means that they can regularly exchange gametes to produce normally-fertile offspring and this also implies that all members belong to the same species. If the gamodeme is very large, and all gene alleles are uniformly distributed by the gametes within it, however, there may be low frequencies of exchange with these neighbours. This may be viewed as the breaking up of a sexual population into smaller overlapping sexual populations. The overall rise in homozygosity is quantified by the inbreeding coefficient, note that all homozygotes are increased in frequency – both the deleterious and the desirable. The mean phenotype of the collection is lower than that of the panmictic original – which is known as inbreeding depression. It is most important to note, however, that some lines will be superior to the panmictic original, while some will be about the same. The probabilities of each can be estimated from those binomial equations, in plant and animal breeding, procedures have been developed which deliberately utilise the effects of dispersion. It can be shown that dispersion-assisted selection leads to the greatest genetic advance and this is so for both allogamous and autogamous gamodemes. In ecology, the population of a species in a certain area can be estimated using the Lincoln Index. As of todays date, the population is estimated by the United States Census Bureau to be 7.496 billion. The US Census Bureau estimates the 7 billion number was surpassed on 12 March 2012, according to papers published by the United States Census Bureau, the world population hit 6.5 billion on 24 February 2006. The United Nations Population Fund designated 12 October 1999 as the day on which world population reached 6 billion. This was about 12 years after world population reached 5 billion in 1987, the population of countries such as Nigeria, is not even known to the nearest million, so there is a considerable margin of error in such estimates. Researcher Carl Haub calculated that a total of over 100 billion people have probably been born in the last 2000 years, Population growth increased significantly as the Industrial Revolution gathered pace from 1700 onwards. In 2007 the United Nations Population Division projected that the population will likely surpass 10 billion in 2055

Spain
–
By population, Spain is the sixth largest in Europe and the fifth in the European Union. Spains capital and largest city is Madrid, other urban areas include Barcelona, Valencia, Seville, Bilbao. Modern humans first arrived in the Iberian Peninsula around 35,000 years ago, in the Middle Ages, the area was conquered by Germanic tribes and later by the Moors. Spain is a democracy organised in the form of a government under a constitutional monarchy. It is a power and a major developed country with the worlds fourteenth largest economy by nominal GDP. Jesús Luis Cunchillos argues that the root of the span is the Phoenician word spy. Therefore, i-spn-ya would mean the land where metals are forged, two 15th-century Spanish Jewish scholars, Don Isaac Abravanel and Solomon ibn Verga, gave an explanation now considered folkloric. Both men wrote in two different published works that the first Jews to reach Spain were brought by ship by Phiros who was confederate with the king of Babylon when he laid siege to Jerusalem. This man was a Grecian by birth, but who had given a kingdom in Spain. He became related by marriage to Espan, the nephew of king Heracles, Heracles later renounced his throne in preference for his native Greece, leaving his kingdom to his nephew, Espan, from whom the country of España took its name. Based upon their testimonies, this eponym would have already been in use in Spain by c.350 BCE, Iberia enters written records as a land populated largely by the Iberians, Basques and Celts. Early on its coastal areas were settled by Phoenicians who founded Western Europe´s most ancient cities Cadiz, Phoenician influence expanded as much of the Peninsula was eventually incorporated into the Carthaginian Empire, becoming a major theater of the Punic Wars against the expanding Roman Empire. After an arduous conquest, the peninsula came fully under Roman Rule, during the early Middle Ages it came under Germanic rule but later, much of it was conquered by Moorish invaders from North Africa. In a process took centuries, the small Christian kingdoms in the north gradually regained control of the peninsula. The last Moorish kingdom fell in the same year Columbus reached the Americas, a global empire began which saw Spain become the strongest kingdom in Europe, the leading world power for a century and a half, and the largest overseas empire for three centuries. Continued wars and other problems led to a diminished status. The Napoleonic invasions of Spain led to chaos, triggering independence movements that tore apart most of the empire, eventually democracy was peacefully restored in the form of a parliamentary constitutional monarchy. Spain joined the European Union, experiencing a renaissance and steady economic growth

England
–
England is a country that is part of the United Kingdom. It shares land borders with Scotland to the north and Wales to the west, the Irish Sea lies northwest of England and the Celtic Sea lies to the southwest. England is separated from continental Europe by the North Sea to the east, the country covers five-eighths of the island of Great Britain in its centre and south, and includes over 100 smaller islands such as the Isles of Scilly, and the Isle of Wight. England became a state in the 10th century, and since the Age of Discovery. The Industrial Revolution began in 18th-century England, transforming its society into the worlds first industrialised nation, Englands terrain mostly comprises low hills and plains, especially in central and southern England. However, there are uplands in the north and in the southwest, the capital is London, which is the largest metropolitan area in both the United Kingdom and the European Union. In 1801, Great Britain was united with the Kingdom of Ireland through another Act of Union to become the United Kingdom of Great Britain and Ireland. In 1922 the Irish Free State seceded from the United Kingdom, leading to the latter being renamed the United Kingdom of Great Britain, the name England is derived from the Old English name Englaland, which means land of the Angles. The Angles were one of the Germanic tribes that settled in Great Britain during the Early Middle Ages, the Angles came from the Angeln peninsula in the Bay of Kiel area of the Baltic Sea. The earliest recorded use of the term, as Engla londe, is in the ninth century translation into Old English of Bedes Ecclesiastical History of the English People. According to the Oxford English Dictionary, its spelling was first used in 1538. The earliest attested reference to the Angles occurs in the 1st-century work by Tacitus, Germania, the etymology of the tribal name itself is disputed by scholars, it has been suggested that it derives from the shape of the Angeln peninsula, an angular shape. An alternative name for England is Albion, the name Albion originally referred to the entire island of Great Britain. The nominally earliest record of the name appears in the Aristotelian Corpus, specifically the 4th century BC De Mundo, in it are two very large islands called Britannia, these are Albion and Ierne. But modern scholarly consensus ascribes De Mundo not to Aristotle but to Pseudo-Aristotle, the word Albion or insula Albionum has two possible origins. Albion is now applied to England in a poetic capacity. Another romantic name for England is Loegria, related to the Welsh word for England, Lloegr, the earliest known evidence of human presence in the area now known as England was that of Homo antecessor, dating to approximately 780,000 years ago. The oldest proto-human bones discovered in England date from 500,000 years ago, Modern humans are known to have inhabited the area during the Upper Paleolithic period, though permanent settlements were only established within the last 6,000 years

Belgium
–
Belgium, officially the Kingdom of Belgium, is a sovereign state in Western Europe bordered by France, the Netherlands, Germany, Luxembourg, and the North Sea. It is a small, densely populated country which covers an area of 30,528 square kilometres and has a population of about 11 million people. Additionally, there is a group of German-speakers who live in the East Cantons located around the High Fens area. Historically, Belgium, the Netherlands and Luxembourg were known as the Low Countries, the region was called Belgica in Latin, after the Roman province of Gallia Belgica. From the end of the Middle Ages until the 17th century, today, Belgium is a federal constitutional monarchy with a parliamentary system of governance. It is divided into three regions and three communities, that exist next to each other and its two largest regions are the Dutch-speaking region of Flanders in the north and the French-speaking southern region of Wallonia. The Brussels-Capital Region is a bilingual enclave within the Flemish Region. A German-speaking Community exists in eastern Wallonia, Belgiums linguistic diversity and related political conflicts are reflected in its political history and complex system of governance, made up of six different governments. Upon its independence, declared in 1830, Belgium participated in the Industrial Revolution and, during the course of the 20th century, possessed a number of colonies in Africa. This continuing antagonism has led to several far-reaching reforms, resulting in a transition from a unitary to a federal arrangement during the period from 1970 to 1993. Belgium is also a member of the Eurozone, NATO, OECD and WTO. Its capital, Brussels, hosts several of the EUs official seats as well as the headquarters of major international organizations such as NATO. Belgium is also a part of the Schengen Area, Belgium is a developed country, with an advanced high-income economy and is categorized as very high in the Human Development Index. A gradual immigration by Germanic Frankish tribes during the 5th century brought the area under the rule of the Merovingian kings, a gradual shift of power during the 8th century led the kingdom of the Franks to evolve into the Carolingian Empire. Many of these fiefdoms were united in the Burgundian Netherlands of the 14th and 15th centuries, the Eighty Years War divided the Low Countries into the northern United Provinces and the Southern Netherlands. The latter were ruled successively by the Spanish and the Austrian Habsburgs and this was the theatre of most Franco-Spanish and Franco-Austrian wars during the 17th and 18th centuries. The reunification of the Low Countries as the United Kingdom of the Netherlands occurred at the dissolution of the First French Empire in 1815, although the franchise was initially restricted, universal suffrage for men was introduced after the general strike of 1893 and for women in 1949. The main political parties of the 19th century were the Catholic Party, French was originally the single official language adopted by the nobility and the bourgeoisie

Netherlands
–
The Netherlands, also informally known as Holland is the main constituent country of the Kingdom of the Netherlands. It is a densely populated country located in Western Europe with three territories in the Caribbean. The European part of the Netherlands borders Germany to the east, Belgium to the south, and the North Sea to the northwest, sharing borders with Belgium, the United Kingdom. The three largest cities in the Netherlands are Amsterdam, Rotterdam and The Hague, Amsterdam is the countrys capital, while The Hague holds the Dutch seat of parliament and government. The port of Rotterdam is the worlds largest port outside East-Asia, the name Holland is used informally to refer to the whole of the country of the Netherlands. Netherlands literally means lower countries, influenced by its low land and flat geography, most of the areas below sea level are artificial. Since the late 16th century, large areas have been reclaimed from the sea and lakes, with a population density of 412 people per km2 –507 if water is excluded – the Netherlands is classified as a very densely populated country. Only Bangladesh, South Korea, and Taiwan have both a population and higher population density. Nevertheless, the Netherlands is the worlds second-largest exporter of food and agricultural products and this is partly due to the fertility of the soil and the mild climate. In 2001, it became the worlds first country to legalise same-sex marriage, the Netherlands is a founding member of the EU, Eurozone, G-10, NATO, OECD and WTO, as well as being a part of the Schengen Area and the trilateral Benelux Union. The first four are situated in The Hague, as is the EUs criminal intelligence agency Europol and this has led to the city being dubbed the worlds legal capital. The country also ranks second highest in the worlds 2016 Press Freedom Index, the Netherlands has a market-based mixed economy, ranking 17th of 177 countries according to the Index of Economic Freedom. It had the thirteenth-highest per capita income in the world in 2013 according to the International Monetary Fund, in 2013, the United Nations World Happiness Report ranked the Netherlands as the seventh-happiest country in the world, reflecting its high quality of life. The Netherlands also ranks joint second highest in the Inequality-adjusted Human Development Index, the region called Low Countries and the country of the Netherlands have the same toponymy. Place names with Neder, Nieder, Nether and Nedre and Bas or Inferior are in use in all over Europe. They are sometimes used in a relation to a higher ground that consecutively is indicated as Upper, Boven, Oben. In the case of the Low Countries / the Netherlands the geographical location of the region has been more or less downstream. The geographical location of the region, however, changed over time tremendously

Germany
–
Germany, officially the Federal Republic of Germany, is a federal parliamentary republic in central-western Europe. It includes 16 constituent states, covers an area of 357,021 square kilometres, with about 82 million inhabitants, Germany is the most populous member state of the European Union. After the United States, it is the second most popular destination in the world. Germanys capital and largest metropolis is Berlin, while its largest conurbation is the Ruhr, other major cities include Hamburg, Munich, Cologne, Frankfurt, Stuttgart, Düsseldorf and Leipzig. Various Germanic tribes have inhabited the northern parts of modern Germany since classical antiquity, a region named Germania was documented before 100 AD. During the Migration Period the Germanic tribes expanded southward, beginning in the 10th century, German territories formed a central part of the Holy Roman Empire. During the 16th century, northern German regions became the centre of the Protestant Reformation, in 1871, Germany became a nation state when most of the German states unified into the Prussian-dominated German Empire. After World War I and the German Revolution of 1918–1919, the Empire was replaced by the parliamentary Weimar Republic, the establishment of the national socialist dictatorship in 1933 led to World War II and the Holocaust. After a period of Allied occupation, two German states were founded, the Federal Republic of Germany and the German Democratic Republic, in 1990, the country was reunified. In the 21st century, Germany is a power and has the worlds fourth-largest economy by nominal GDP. As a global leader in industrial and technological sectors, it is both the worlds third-largest exporter and importer of goods. Germany is a country with a very high standard of living sustained by a skilled. It upholds a social security and universal health system, environmental protection. Germany was a member of the European Economic Community in 1957. It is part of the Schengen Area, and became a co-founder of the Eurozone in 1999, Germany is a member of the United Nations, NATO, the G8, the G20, and the OECD. The national military expenditure is the 9th highest in the world, the English word Germany derives from the Latin Germania, which came into use after Julius Caesar adopted it for the peoples east of the Rhine. This in turn descends from Proto-Germanic *þiudiskaz popular, derived from *þeudō, descended from Proto-Indo-European *tewtéh₂- people, the discovery of the Mauer 1 mandible shows that ancient humans were present in Germany at least 600,000 years ago. The oldest complete hunting weapons found anywhere in the world were discovered in a mine in Schöningen where three 380, 000-year-old wooden javelins were unearthed

Turkey
–
Turkey, officially the Republic of Turkey, is a transcontinental country in Eurasia, mainly in Anatolia in Western Asia, with a smaller portion on the Balkan peninsula in Southeast Europe. Turkey is a democratic, secular, unitary, parliamentary republic with a cultural heritage. The country is encircled by seas on three sides, the Aegean Sea is to the west, the Black Sea to the north, and the Mediterranean Sea to the south. The Bosphorus, the Sea of Marmara, and the Dardanelles, Ankara is the capital while Istanbul is the countrys largest city and main cultural and commercial centre. Approximately 70-80% of the countrys citizens identify themselves as ethnic Turks, other ethnic groups include legally recognised and unrecognised minorities. Kurds are the largest ethnic minority group, making up approximately 20% of the population, the area of Turkey has been inhabited since the Paleolithic by various ancient Anatolian civilisations, as well as Assyrians, Greeks, Thracians, Phrygians, Urartians and Armenians. After Alexander the Greats conquest, the area was Hellenized, a process continued under the Roman Empire. The Seljuk Sultanate of Rûm ruled Anatolia until the Mongol invasion in 1243, the empire reached the peak of its power in the 16th century, especially during the reign of Suleiman the Magnificent. During the war, the Ottoman government committed genocides against its Armenian, Assyrian, following the war, the conglomeration of territories and peoples that formerly comprised the Ottoman Empire was partitioned into several new states. Turkey is a member of the UN, an early member of NATO. Turkeys growing economy and diplomatic initiatives have led to its recognition as a regional power while her location has given it geopolitical, the name of Turkey is based on the ethnonym Türk. The first recorded use of the term Türk or Türük as an autonym is contained in the Old Turkic inscriptions of the Göktürks of Central Asia, the English name Turkey first appeared in the late 14th century and is derived from Medieval Latin Turchia. Similarly, the medieval Khazar Empire, a Turkic state on the shores of the Black. The medieval Arabs referred to the Mamluk Sultanate as al-Dawla al-Turkiyya, the Ottoman Empire was sometimes referred to as Turkey or the Turkish Empire among its European contemporaries. The Anatolian peninsula, comprising most of modern Turkey, is one of the oldest permanently settled regions in the world, various ancient Anatolian populations have lived in Anatolia, from at least the Neolithic period until the Hellenistic period. Many of these peoples spoke the Anatolian languages, a branch of the larger Indo-European language family, in fact, given the antiquity of the Indo-European Hittite and Luwian languages, some scholars have proposed Anatolia as the hypothetical centre from which the Indo-European languages radiated. The European part of Turkey, called Eastern Thrace, has also been inhabited since at least forty years ago. It is the largest and best-preserved Neolithic site found to date, the settlement of Troy started in the Neolithic Age and continued into the Iron Age

Saudi Arabia
–
Saudi Arabia is bordered by Jordan and Iraq to the north, Kuwait to the northeast, Qatar, Bahrain and the United Arab Emirates to the east, Oman to the southeast and Yemen to the south. It is separated from Israel and Egypt by the Gulf of Aqaba and it is the only nation with both a Red Sea coast and a Persian Gulf coast and most of its terrain consists of arid desert and mountains. The area of modern-day Saudi Arabia formerly consisted of four regions, Hejaz, Najd and parts of Eastern Arabia. The Kingdom of Saudi Arabia was founded in 1932 by Ibn Saud and he united the four regions into a single state through a series of conquests beginning in 1902 with the capture of Riyadh, the ancestral home of his family, the House of Saud. Saudi Arabia has since been a monarchy, effectively a hereditary dictatorship governed along Islamic lines. The ultraconservative Wahhabi religious movement within Sunni Islam has been called the predominant feature of Saudi culture, with its global spread largely financed by the oil and gas trade. Saudi Arabia is sometimes called the Land of the Two Holy Mosques in reference to Al-Masjid al-Haram and Al-Masjid an-Nabawi, the state has a total population of 28.7 million, of which 20 million are Saudi nationals and 8 million are foreigners. The states official language is Arabic, petroleum was discovered on 3 March 1938 and followed up by several other finds in the Eastern Province. Saudi Arabia has since become the worlds largest oil producer and exporter, controlling the second largest oil reserves. The kingdom is categorized as a World Bank high-income economy with a high Human Development Index and is the only Arab country to be part of the G-20 major economies. However, the economy of Saudi Arabia is the least diversified in the Gulf Cooperation Council, the state has attracted criticism for its treatment of women and use of capital punishment. Saudi Arabia is an autocracy, has the fourth highest military expenditure in the world. Saudi Arabia is considered a regional and middle power, in addition to the GCC, it is an active member of the Organisation of Islamic Cooperation and OPEC. Following the unification of the Hejaz and Nejd kingdoms, the new state was named al-Mamlakah al-ʻArabīyah as-Suʻūdīyah by royal decree on 23 September 1932 by its founder, Abdulaziz Al Saud. Although this is translated as the Kingdom of Saudi Arabia in English it literally means the Saudi Arab kingdom. Its inclusion expresses the view that the country is the possession of the royal family. Al Saud is an Arabic name formed by adding the word Al, meaning family of or House of, in the case of the Al Saud, this is the father of the dynastys 18th century founder, Muhammad bin Saud. There is evidence that human habitation in the Arabian Peninsula dates back to about 125,000 years ago

Bahrain
–
Bahrain, officially the Kingdom of Bahrain, is a small Arab monarchy in the Persian Gulf. Bahrains population is 1,234,567, including 666,172 non-nationals and it is 780 km2 in size, making it the third smallest nation in Asia after the Maldives and Singapore. Bahrain is the site of the ancient Dilmun civilisation and it has been famed since antiquity for its pearl fisheries, which were considered the best in the world into the 19th century. Bahrain was one of the earliest areas to convert to Islam, following a period of Arab rule, Bahrain was occupied by the Portuguese in 1521, who in turn were expelled in 1602 by Shah Abbas I of the Safavid dynasty under the Persian Empire. In 1783, the Bani Utbah clan captured Bahrain from Nasr Al-Madhkur and it has since been ruled by the Al Khalifa royal family, in the late 1800s, following successive treaties with the British, Bahrain became a protectorate of the United Kingdom. Formerly a state, Bahrain was declared a Kingdom in 2002, in 2011, the country experienced protests inspired by the regional Arab Spring. Bahrain had the first post-oil economy in the Persian Gulf, since the late 20th century, Bahrain has invested in the banking and tourism sectors. Many large financial institutions have a presence in Manama, the countrys capital, Bahrain has a high Human Development Index and was recognised by the World Bank as a high income economy. In Arabic, Bahrayn is the form of bahr, so al-Bahrayn means the two seas, although which two seas were originally intended remains in dispute. The term appears five times in the Quran, but does not refer to the modern island—originally known to the Arabs as Awal— but rather to all of Eastern Arabia. Today, Bahrains two seas are generally taken to be the bay east and west of the island. In addition to wells, there are areas of the sea north of Bahrain where fresh water bubbles up in the middle of the water as noted by visitors since antiquity. An alternate theory with regard to Bahrains toponymy is offered by the al-Ahsa region, another supposition by al-Jawahari suggests that the more formal name Bahri would have been misunderstood and so was opted against. Until the late Middle Ages, Bahrain referred to the region of Eastern Arabia that included Southern Iraq, Kuwait, Al-Hasa, Qatif, the region stretched from Basra in Iraq to the Strait of Hormuz in Oman. This was Iqlīm al-Bahrayns Bahrayn Province, the exact date at which the term Bahrain began to refer solely to the Awal archipelago is unknown. The entire coastal strip of Eastern Arabia was known as Bahrain for a millennium, the island and kingdom were also commonly spelled Bahrein into the 1950s. Bahrain was home to the Dilmun civilization, an important Bronze Age trade centre linking Mesopotamia, Bahrain was later ruled by the Assyrians and Babylonians. From the 6th to 3rd century BC, Bahrain was part of the Persian Empire ruled by the Achaemenian dynasty, by about 250 BC, Parthia brought the Persian Gulf under its control and extended its influence as far as Oman

Qatar
–
Qatar, officially the State of Qatar, is a sovereign country located in Western Asia, occupying the small Qatar Peninsula on the northeastern coast of the Arabian Peninsula. Its sole land border is with Saudi Arabia to the south, with the rest of its surrounded by the Persian Gulf. A strait in the Persian Gulf separates Qatar from the island country of Bahrain, as well as sharing maritime borders with the United Arab Emirates. Following Ottoman rule, Qatar became a British protectorate in the early 20th century until gaining independence in 1971, Qatar has been ruled by the House of Thani since the early 19th century. Sheikh Jassim bin Mohammed Al Thani was the founder of the State of Qatar, Qatar is a hereditary monarchy and its head of state is Emir Sheikh Tamim bin Hamad Al Thani. Whether it should be regarded as a constitutional or a monarchy is a matter of opinion. In 2003, the constitution was approved in a referendum. In early 2017, Qatars total population was 2.3 million,313,000 Qatari citizens and 2.6 million expatriates, Qatar is a high income economy and is a developed country, backed by the worlds third largest natural gas reserves and oil reserves. The country has the highest per capita income in the world, Qatar is classified by the UN as a country of very high human development and is the most advanced Arab state for human development. Qatar is a significant power in the Arab world, supporting several rebel groups during the Arab Spring both financially and through its globally expanding media group, Al Jazeera Media Network. For its size, Qatar wields disproportionate influence in the world, Qatar will host the 2022 FIFA World Cup, becoming the first Arab country to do so. A century later, Ptolemy produced the first known map to depict the peninsula, the map also referenced a town named Cadara to the east of the peninsula. The term Catara was exclusively used until the 18th century, after which Katara emerged as the most commonly recognised spelling, eventually, the modern derivative Qatar was adopted as the countrys name. In Standard Arabic, the name is pronounced, while in the local dialect it is, Human habitation of Qatar dates back to 50,000 years ago. Settlements and tools dating back to the Stone Age have been unearthed in the peninsula, Mesopotamian artefacts originating from the Ubaid period have been discovered in abandoned coastal settlements. Al Daasa, a settlement located on the western coast of Qatar, is the most important Ubaid site in the country and is believed to have accommodated a small seasonal encampment. Kassite Babylonian material dating back to the second millennium BC found in Al Khor Islands attests to trade relations between the inhabitants of Qatar and the Kassites in modern-day Bahrain, among the findings were 3,000,000 crushed snail shells and Kassite potsherds. It has been suggested that Qatar is the earliest known site of shellfish dye production, in 224 AD, the Sasanian Empire gained control over the territories surrounding the Persian Gulf

United Arab Emirates
–
In 2013, the UAEs population was 9.2 million, of which 1.4 million are Emirati citizens and 7.8 million are expatriates. The country is a federation of seven emirates, and was established on 2 December 1971, the constituent emirates are Abu Dhabi, Ajman, Dubai, Fujairah, Ras al-Khaimah, Sharjah and Umm al-Quwain. Each emirate is governed by a monarch, together, they jointly form the Federal Supreme Council. One of the monarchs is selected as the President of the United Arab Emirates, Islam is the official religion of the UAE and Arabic is the official language. The UAEs oil reserves are the seventh-largest in the world while its natural gas reserves are the worlds seventeenth-largest, Sheikh Zayed, ruler of Abu Dhabi and the first President of the UAE, oversaw the development of the Emirates and steered oil revenues into healthcare, education and infrastructure. The UAEs economy is the most diversified in the Gulf Cooperation Council, while its most populous city of Dubai is an important global city, nevertheless, the country remains principally reliant on its export of petroleum and natural gas. The UAE is criticised for its rights record, including the specific interpretations of Sharia used in its legal system. The UAEs rising international profile has led analysts to identify it as a regional. It appears the land of the Emirates has been occupied for thousands of years, there is no proof of contact with the outside world at that stage, although in time it developed with civilisations in Mesopotamia and Iran. This contact persisted and became wide-ranging, probably motivated by trade in copper from the Hajar Mountains, in ancient times, Al Hasa was part of Al Bahreyn and adjoined Greater Oman. Sassanid groups were present on the Batinah coast, in 637, Julfar was an important port that was used as a staging post for the Islamic invasion of the Sassanian Empire. The area of the Al Ain/Buraimi Oasis was known as Tuam and was an important trading post for camel routes between the coast and the Arabian interior. The earliest Christian site in the UAE was first discovered in the 1990s, a monastic complex on what is now known as Sir Bani Yas Island. Thought to be Nestorian and built in 600 AD, the church appears to have been abandoned peacefully in 750 AD and it forms a rare physical link to a legacy of Christianity which is thought to have spread across the peninsula from 50 to 350 AD following trade routes. Certainly, by the 5th century, Oman had a bishop named John – the last bishop of Oman being Etienne, in 676 AD. This led to a group of travelling to Medina, converting to Islam and subsequently driving a successful uprising against the unpopular Sassanids. Following the death of Prophet Muhammad, the new Islamic communities south of the Persian Gulf threatened to disintegrate, with insurrections against the Muslim leaders. The Caliph Abu Bakr sent an army from the capital Medina which completed its reconquest of the territory with the battle of Dibba in which 10,000 lives are thought to have been lost

Iran, also known as Persia, officially the Islamic Republic of Iran, is a sovereign state in Western Asia. Comprising a land area of 1,648,195 km2, it is the second-largest country in the Middle East, with 82.8 million inhabitants, Iran is the worlds 17th-most-populous country. It is the country with both a Caspian Sea and an Indian Ocean coastline. The countrys central location in Eurasia and Western Asia, and its proximity to the Strait of Hormuz, Tehran is the countrys capital and largest city, as well as its leading economic and cultural center. Iran is the site of to one of the worlds oldest civilizations, the area was first unified by the Iranian Medes in 625 BC, who became the dominant cultural and political power in the region. The empire collapsed in 330 BC following the conquests of Alexander the Great, under the Sassanid Dynasty, Iran again became one of the leading powers in the world for the next four centuries. Beginning in 633 AD, Arabs conquered Iran and largely displaced the indigenous faiths of Manichaeism and Zoroastrianism by Islam, Iran became a major contributor to the Islamic Golden Age that followed, producing many influential scientists, scholars, artists, and thinkers. During the 18th century, Iran reached its greatest territorial extent since the Sassanid Empire, through the late 18th and 19th centuries, a series of conflicts with Russia led to significant territorial losses and the erosion of sovereignty. Popular unrest culminated in the Persian Constitutional Revolution of 1906, which established a monarchy and the countrys first legislative body. Following a coup instigated by the U. K. Growing dissent against foreign influence and political repression led to the 1979 Revolution, Irans rich cultural legacy is reflected in part by its 21 UNESCO World Heritage Sites, the third-largest number in Asia and 11th-largest in the world. Iran is a member of the UN, ECO, NAM, OIC. Its political system is based on the 1979 Constitution which combines elements of a democracy with a theocracy governed by Islamic jurists under the concept of a Supreme Leadership. A multicultural country comprising numerous ethnic and linguistic groups, most inhabitants are Shia Muslims, the largest ethnic groups in Iran are the Persians, Azeris, Kurds and Lurs. Historically, Iran has been referred to as Persia by the West, due mainly to the writings of Greek historians who called Iran Persis, meaning land of the Persians. As the most extensive interactions the Ancient Greeks had with any outsider was with the Persians, however, Persis was originally referred to a region settled by Persians in the west shore of Lake Urmia, in the 9th century BC. The settlement was then shifted to the end of the Zagros Mountains. In 1935, Reza Shah requested the international community to refer to the country by its native name, opposition to the name change led to the reversal of the decision, and Professor Ehsan Yarshater, editor of Encyclopædia Iranica, propagated a move to use Persia and Iran interchangeably

Hong Kong, officially the Hong Kong Special Administrative Region of the Peoples Republic of China, is an autonomous territory on the Pearl River Delta of East Asia. Macau lies across the delta to the west, and the Chinese province of Guangdong borders the territory to the north. With a total area of 1,106 square kilometres. Hong Kong was later occupied by Japan during World War II until British control resumed in 1945, under the principle of one country, two systems, Hong Kong maintains a separate political and economic system from China. Except in military defence and foreign affairs, Hong Kong maintains its independent executive, legislative, in addition, Hong Kong develops relations directly with foreign states and international organisations in a broad range of appropriate fields. Hong Kong is one of the worlds most significant financial centres, with the highest Financial Development Index score and consistently ranks as the worlds most competitive and freest economic entity. As the worlds 8th largest trading entity, its legal tender, Hong Kongs tertiary sector dominated economy is characterised by simple taxation with a competitive level of corporate tax and supported by its independent judiciary system. However, while Hong Kong has one of the highest per capita incomes in the world and it has a very high Human Development Index ranking and the worlds longest life expectancy. Over 90% of the population use of well-developed public transportation. Seasonal air pollution with origins from neighbouring areas of Mainland China. Hong Kong was officially recorded in the 1842 Treaty of Nanking to encompass the entirety of the island, before 1842, the name referred to a small inlet—now Aberdeen Harbour, literally means Little Hong Kong)—between Aberdeen Island and the southern coast of Hong Kong Island. Aberdeen was a point of contact between British sailors and local fishermen. Detailed and accurate romanisation systems for Cantonese were available and in use at the time, fragrance may refer to the sweet taste of the harbours fresh water estuarine influx of the Pearl River or to the incense from factories lining the coast of northern Kowloon. The incense was stored near Aberdeen Harbour for export before Hong Kong developed Victoria Harbour, the name had often been written as the single word Hongkong until the government adopted the current form in 1926. Nevertheless, a number of century-old institutions still retain the form, such as the Hongkong Post, Hongkong Electric. As of 1997, its name is the Hong Kong Special Administrative Region of the Peoples Republic of China. This is the title as mentioned in the Hong Kong Basic Law. Hong Kong has carried many nicknames, the most famous among those is the Pearl of the Orient, which reflected the impressive nightscape of the citys light decorations on the skyscrapers along both sides of the Victoria Harbour

Japan is a sovereign island nation in Eastern Asia. Located in the Pacific Ocean, it lies off the eastern coast of the Asia Mainland and stretches from the Sea of Okhotsk in the north to the East China Sea, the kanji that make up Japans name mean sun origin. 日 can be read as ni and means sun while 本 can be read as hon, or pon, Japan is often referred to by the famous epithet Land of the Rising Sun in reference to its Japanese name. Japan is an archipelago consisting of about 6,852 islands. The four largest are Honshu, Hokkaido, Kyushu and Shikoku, the country is divided into 47 prefectures in eight regions. Hokkaido being the northernmost prefecture and Okinawa being the southernmost one, the population of 127 million is the worlds tenth largest. Japanese people make up 98. 5% of Japans total population, approximately 9.1 million people live in the city of Tokyo, the capital of Japan. Archaeological research indicates that Japan was inhabited as early as the Upper Paleolithic period, the first written mention of Japan is in Chinese history texts from the 1st century AD. Influence from other regions, mainly China, followed by periods of isolation, from the 12th century until 1868, Japan was ruled by successive feudal military shoguns who ruled in the name of the Emperor. Japan entered into a period of isolation in the early 17th century. The Second Sino-Japanese War of 1937 expanded into part of World War II in 1941, which came to an end in 1945 following the bombings of Hiroshima and Nagasaki. Japan is a member of the UN, the OECD, the G7, the G8, the country has the worlds third-largest economy by nominal GDP and the worlds fourth-largest economy by purchasing power parity.

Japan is a country with a very high standard of living. Its population enjoys the highest life expectancy and the third lowest infant mortality rate in the world, in ancient China, Japan was called Wo 倭. It was mentioned in the third century Chinese historical text Records of the Three Kingdoms in the section for the Wei kingdom, Wa became disliked because it has the connotation of the character 矮, meaning dwarf. The 倭 kanji has been replaced with the homophone Wa, meaning harmony, the Japanese word for Japan is 日本, which is pronounced Nippon or Nihon and literally means the origin of the sun. The earliest record of the name Nihon appears in the Chinese historical records of the Tang dynasty, at the start of the seventh century, a delegation from Japan introduced their country as Nihon

Rose-ringed parakeet
–
The rose-ringed parakeet, also known as the ring-necked parakeet, is a gregarious tropical Afro-Asian parakeet species that has an extremely large range. The rose-ringed parakeet is sexually dimorphic, the adult male sports a red or black neck ring and the hen and immature birds of both sexes either show no neck rings, or display shadow-like pale to dark grey neck rings. Both sexes have a green colour. Rose-ringed parakeets measure on average 40 cm in length, including the tail feathers and their average single-wing length is about 15–17.5 cm. In the wild, this is a species with an unmistakable squawking call. It is herbivorous and not migratory, one of the few parrot species that have successfully adapted to living in disturbed habitats, it has withstood the onslaught of urbanisation and deforestation. The genus name Psittacula is a diminutive of Latin psittacus, parrot, resident among the Nile valley and certainly Giza, it is sometimes seen on the north coast and Sinai. The African parakeet also started to breed in Israel in the 1980s and is considered an invasive species, in Australia, Great Britain, the United States, and other western countries, it is often referred to as the Indian ringneck parrot. Boreal rose-ringed parakeet is distributed in Bangladesh, Pakistan, northern India and Nepal to central Burma, a phylogenetic analysis using DNA showed that the Mauritius parakeet is closely related to this species, and probably needs to be placed between the African and Asian subspecies. In the wild, rose-ringed parakeets usually feed on buds, fruits, vegetables, nuts, berries, wild flocks also fly several miles to forage in farmlands and orchards, causing extensive damage. In India, they feed on grains, and during winter also on pigeon peas. In Egypt during the spring, they feed on mulberry and in summer they feed on dates and nest inside palm trees and eat from sunflower and corn fields. In captivity, rose-ringed parakeets will take a variety of food and can be fed on a number of fruits, vegetables, pellets, seeds. Oils, salts, chocolate, alcohol, and other preservatives should be avoided, in north-west India, Indian rose-ringed parakeets form pairs from September to December. They do not have life mates and often breed with another partner during the breeding season. During this cold season, they select and defend nest sites, feeding on winter pea crops provides the female with nutrients necessary for egg production. From April to June, they care for their young, fledgings are ready to leave the nest before monsoon. Rose-ringed parakeets are popular as pets and they have a history in aviculture

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

Mathurin Jacques Brisson
–
Mathurin Jacques Brisson was a French zoologist and natural philosopher. The earlier part of his life was spent in the pursuit of natural history, his works in this field included Le Règne animal. As a young man, he was a disciple and assistant of R. A. F. Reaumur, for a period of time he was an instructor of physical sciences and natural history to the family of the monarch. He held the chair of physics at the College of Navarre, a significant work involving the specific weight of bodies was his Pesanteur Spécifique des Corps. In his investigations of electricity, Brisson was opposed to the theories of Priestley and he died at Croissy-sur-Seine near Paris.

Gingee
–
Gingee is a panchayat town in Villupuram district in the Indian state of Tamil Nadu. The nearest town with a station is Tindivanam,28 km away. Gingee is located between three hills covering a perimeter of 3 km, Gingee is famous for its Gingee Fort, a popular tourist attraction. The Kon dynasty laid the foundations for the Gingee Fort in 1190 AD, the fort was later built by the Chola dynasty in the 13th century. In 1638, Gingee came under the control of Bijapur Sultanate from Vijayanagar, in 1677, it was under the control of Maratha king Shivaji. In 1690, it came under the Mughals, when it became the headquarters of Arcot and it changed hands to the French in 1750, and then to the British in 1762. During this time, many aspects of Gingee were shifted to Pondicherry by the French. To visit Gingee fort, guides are available from archaeological office which is on the way to the fort, the office is open for visitors from 9,00 to 17,00. The founding of the Kon dynasty provides the launching of Gingee as a royal center. The Gingee country then came under the rule of the Hoysalas in the part of the 13th. From the Hoysalas it passed on, by relatively easy efforts, the Vijayanagar dominion gradually expanded over South India and divided the administration into three important provinces, which were under the control of Nayaks. These were the Nayaks of Madurai, Nayaks of Tanjore and Nayaks of Gingee, information about the Gingee Nayaks and their rule is very scanty. It is said that Tupakula Krishnappa Nayaka of a Chandragiri family was the founder of the Nayaka line of Gingee kings and he seems to have ruled gloriously all over the coast from Nellore down to the Coleroon up to 1521 AD. Under the Nayaks the forts were strengthened and the town was greatly enlarged, the last Nayak of Gingee was forced to surrender to the Bijapur army towards the end of December 1649 AD. The booty acquired by the Mohammedan rulers of Bijapur was 20 crores of rupees in cash, Gingee assumed a new and enhanced strategic importance under the Bijapur governors. Bijapur was in possession of the fortress of Gingee till 1677 AD, when Chatrapati Shivaji, the Marathas greatly strengthened and fortified its defences. The Mughals were then able to capture the fort of Gingee in the Carnatic from Rajaram the King of the Marathas, early in 1698, after a siege of seven years. After that Aurangazeb, granted a mansab of 2,500 rank and jagir of 12 lakhs to Raja Swarup Singh, Raja Swarup Singh died of old age in 1714 AD

It shares land borders with Pakistan to the west, China, Nepal, and Bhutan to the northeast, in the Indian Ocean, India is in the vicinity of Sri Lanka and the Maldives. Indias Andaman and Nicobar Islands share a border with Thailand. The Indian subcontinent was home to the urban Indus Valley Civilisation of the 3rd millennium BCE, in the following millennium, the oldest scriptures associated with Hinduism began to be composed. Social stratification, based on caste, emerged in the first millennium BCE, early political consolidations took place under the Maurya and Gupta empires, the later peninsular Middle Kingdoms influenced cultures as far as southeast Asia. In the medieval era, Judaism, Zoroastrianism, Christianity, and Islam arrived, much of the north fell to the Delhi sultanate, the south was united under the Vijayanagara Empire. The economy expanded in the 17th century in the Mughal empire, in the mid-18th century, the subcontinent came under British East India Company rule, and in the mid-19th under British crown rule. A nationalist movement emerged in the late 19th century, which later, under Mahatma Gandhi, was noted for nonviolent resistance, in 2015, the Indian economy was the worlds seventh largest by nominal GDP and third largest by purchasing power parity. Following market-based economic reforms in 1991, India became one of the major economies and is considered a newly industrialised country. However, it continues to face the challenges of poverty, corruption, malnutrition, a nuclear weapons state and regional power, it has the third largest standing army in the world and ranks sixth in military expenditure among nations. India is a constitutional republic governed under a parliamentary system. It is a pluralistic, multilingual and multi-ethnic society and is home to a diversity of wildlife in a variety of protected habitats. The name India is derived from Indus, which originates from the Old Persian word Hindu, the latter term stems from the Sanskrit word Sindhu, which was the historical local appellation for the Indus River. The ancient Greeks referred to the Indians as Indoi, which translates as The people of the Indus, the geographical term Bharat, which is recognised by the Constitution of India as an official name for the country, is used by many Indian languages in its variations. Scholars believe it to be named after the Vedic tribe of Bharatas in the second millennium B. C. E and it is also traditionally associated with the rule of the legendary emperor Bharata. Gaṇarājya is the Sanskrit/Hindi term for republic dating back to the ancient times, hindustan is a Persian name for India dating back to the 3rd century B. C. E. It was introduced into India by the Mughals and widely used since then and its meaning varied, referring to a region that encompassed northern India and Pakistan or India in its entirety

Latin
–
Latin is a classical language belonging to the Italic branch of the Indo-European languages. The Latin alphabet is derived from the Etruscan and Greek alphabets, Latin was originally spoken in Latium, in the Italian Peninsula. Through the power of the Roman Republic, it became the dominant language, Vulgar Latin developed into the Romance languages, such as Italian, Portuguese, Spanish, French, and Romanian. Latin, Italian and French have contributed many words to the English language, Latin and Ancient Greek roots are used in theology, biology, and medicine. By the late Roman Republic, Old Latin had been standardised into Classical Latin, Vulgar Latin was the colloquial form spoken during the same time and attested in inscriptions and the works of comic playwrights like Plautus and Terence. Late Latin is the language from the 3rd century. Later, Early Modern Latin and Modern Latin evolved, Latin was used as the language of international communication, scholarship, and science until well into the 18th century, when it began to be supplanted by vernaculars. Ecclesiastical Latin remains the language of the Holy See and the Roman Rite of the Catholic Church. Today, many students, scholars and members of the Catholic clergy speak Latin fluently and it is taught in primary, secondary and postsecondary educational institutions around the world. The language has been passed down through various forms, some inscriptions have been published in an internationally agreed, monumental, multivolume series, the Corpus Inscriptionum Latinarum. Authors and publishers vary, but the format is about the same, volumes detailing inscriptions with a critical apparatus stating the provenance, the reading and interpretation of these inscriptions is the subject matter of the field of epigraphy. The works of several hundred ancient authors who wrote in Latin have survived in whole or in part and they are in part the subject matter of the field of classics. The Cat in the Hat, and a book of fairy tales, additional resources include phrasebooks and resources for rendering everyday phrases and concepts into Latin, such as Meissners Latin Phrasebook. The Latin influence in English has been significant at all stages of its insular development. From the 16th to the 18th centuries, English writers cobbled together huge numbers of new words from Latin and Greek words, dubbed inkhorn terms, as if they had spilled from a pot of ink. Many of these words were used once by the author and then forgotten, many of the most common polysyllabic English words are of Latin origin through the medium of Old French. Romance words make respectively 59%, 20% and 14% of English, German and those figures can rise dramatically when only non-compound and non-derived words are included. Accordingly, Romance words make roughly 35% of the vocabulary of Dutch, Roman engineering had the same effect on scientific terminology as a whole

Ancient Greek
–
Ancient Greek includes the forms of Greek used in ancient Greece and the ancient world from around the 9th century BC to the 6th century AD. It is often divided into the Archaic period, Classical period. It is antedated in the second millennium BC by Mycenaean Greek, the language of the Hellenistic phase is known as Koine. Koine is regarded as a historical stage of its own, although in its earliest form it closely resembled Attic Greek. Prior to the Koine period, Greek of the classic and earlier periods included several regional dialects, Ancient Greek was the language of Homer and of fifth-century Athenian historians, playwrights, and philosophers. It has contributed many words to English vocabulary and has been a subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Epic and Classical phases of the language, Ancient Greek was a pluricentric language, divided into many dialects. The main dialect groups are Attic and Ionic, Aeolic, Arcadocypriot, some dialects are found in standardized literary forms used in literature, while others are attested only in inscriptions. There are also several historical forms, homeric Greek is a literary form of Archaic Greek used in the epic poems, the Iliad and Odyssey, and in later poems by other authors. Homeric Greek had significant differences in grammar and pronunciation from Classical Attic, the origins, early form and development of the Hellenic language family are not well understood because of a lack of contemporaneous evidence. Several theories exist about what Hellenic dialect groups may have existed between the divergence of early Greek-like speech from the common Proto-Indo-European language and the Classical period and they have the same general outline, but differ in some of the detail. The invasion would not be Dorian unless the invaders had some relationship to the historical Dorians. The invasion is known to have displaced population to the later Attic-Ionic regions, the Greeks of this period believed there were three major divisions of all Greek people—Dorians, Aeolians, and Ionians, each with their own defining and distinctive dialects. Often non-west is called East Greek, Arcadocypriot apparently descended more closely from the Mycenaean Greek of the Bronze Age. Boeotian had come under a strong Northwest Greek influence, and can in some respects be considered a transitional dialect, thessalian likewise had come under Northwest Greek influence, though to a lesser degree. Most of the dialect sub-groups listed above had further subdivisions, generally equivalent to a city-state and its surrounding territory, Doric notably had several intermediate divisions as well, into Island Doric, Southern Peloponnesus Doric, and Northern Peloponnesus Doric. The Lesbian dialect was Aeolic Greek and this dialect slowly replaced most of the older dialects, although Doric dialect has survived in the Tsakonian language, which is spoken in the region of modern Sparta. Doric has also passed down its aorist terminations into most verbs of Demotic Greek, by about the 6th century AD, the Koine had slowly metamorphosized into Medieval Greek

Genetic analysis
–
Genetic analysis is the overall process of studying and researching in fields of science that involve genetics and molecular biology. There are a number of applications that are developed from research. The base system of analysis revolves around general genetics, basic studies include identification of genes and inherited disorders. This research has been conducted for centuries on both a physical observation basis and on a more microscopic scale. Genetic analysis can be used generally to describe methods both used in and resulting from the sciences of genetics and molecular biology, or to applications resulting from this research. Genetic analysis may be done to identify genetic/inherited disorders and also to make a diagnosis in certain somatic diseases such as cancer. Genetic analyses of cancer include detection of mutations, fusion genes, much of the research that set the foundation of genetic analysis began in prehistoric times. Early humans found that they could practice selective breeding to improve crops and they also identified inherited traits in humans that were eliminated over the years. The many genetic analyses gradually evolved over time, modern genetic analysis began in the mid-1800s with research conducted by Gregor Mendel. Mendel, who is known as the father of genetics, was inspired to study variation in plants. Between 1856 and 1863, Mendel cultivated and tested some 29,000 pea plants and this study showed that one in four pea plants had purebred recessive alleles, two out of four were hybrid and one out of four were purebred dominant. His experiments led him to make two generalizations, the Law of Segregation and the Law of Independent Assortment, which became known as Mendels Laws of Inheritance. Later, it was found that units within each cell are responsible for these traits, each gene is defined by a series of amino acids that create proteins responsible for genetic traits. Genetic analyses include molecular technologies such as PCR, RT-PCR, DNA sequencing, and DNA microarrays, DNA sequencing is essential to the applications of genetic analysis. This process is used to determine the order of nucleotide bases, each molecule of DNA is made from adenine, guanine, cytosine and thymine, which determine what function the genes will possess. This was first discovered during the 1970s, DNA sequencing encompasses biochemical methods for determining the order of the nucleotide bases, adenine, guanine, cytosine, and thymine, in a DNA oligonucleotide. By generating a DNA sequence for an organism, you are determining the patterns that make up genetic traits. The advent of DNA sequencing has significantly accelerated biological research and discovery, cytogenetics is a branch of genetics that is concerned with the study of the structure and function of the cell, especially the chromosomes

Mitochondrion
–
The mitochondrion is a double membrane-bound organelle found in all eukaryotic organisms. Some cells in multicellular organisms may however lack them. A number of organisms, such as microsporidia, parabasalids. To date, only one eukaryote, Monocercomonoides, is known to have completely lost its mitochondria, the word mitochondrion comes from the Greek μίτος, mitos, thread, and χονδρίον, chondrion, granule or grain-like. Mitochondria generate most of the supply of adenosine triphosphate, used as a source of chemical energy. Mitochondria are commonly between 0.75 and 3 μm in diameter but vary considerably in size and structure, unless specifically stained, they are not visible. Mitochondrial biogenesis is in turn temporally coordinated with these cellular processes, Mitochondria have been implicated in several human diseases, including mitochondrial disorders, cardiac dysfunction, heart failure and autism. The number of mitochondria in a cell can vary widely by organism, tissue, for instance, red blood cells have no mitochondria, whereas liver cells can have more than 2000, The organelle is composed of compartments that carry out specialized functions. These compartments or regions include the outer membrane, the space, the inner membrane. Although most of a cells DNA is contained in the cell nucleus, mitochondrial proteins vary depending on the tissue and the species. In humans,615 distinct types of protein have been identified from cardiac mitochondria, the mitochondrial proteome is thought to be dynamically regulated. The first observations of structures that probably represented mitochondria were published in the 1840s. Richard Altmann, in 1890, established them as cell organelles, the term mitochondria was coined by Carl Benda in 1898. Leonor Michaelis discovered that Janus green can be used as a stain for mitochondria in 1900. Benjamin F. Kingsbury, in 1912, first related them with cell respiration, in 1913, particles from extracts of guinea-pig liver were linked to respiration by Otto Heinrich Warburg, which he called grana. Warburg and Heinrich Otto Wieland, who had postulated a similar particle mechanism. It was not until 1925, when David Keilin discovered cytochromes, in the following years, the mechanism behind cellular respiration was further elaborated, although its link to the mitochondria was not known. The introduction of tissue fractionation by Albert Claude allowed mitochondria to be isolated from other cell fractions, in 1946, he concluded that cytochrome oxidase and other enzymes responsible for the respiratory chain were isolated to the mitchondria

Cytochrome b
–
Cytochrome b is a protein found in the mitochondria of eukaryotic cells. It functions as part of the transport chain and is the main subunit of transmembrane cytochrome bc1. In the mitochondrion of eukaryotes and in prokaryotes, cytochrome b is a component of respiratory chain complex III — also known as the bc1 complex or ubiquinol-cytochrome c reductase. In plant chloroplasts and cyanobacteria, there is a protein, cytochrome b6. These complexes are involved in transport, the pumping of protons to create a proton-motive force. This proton gradient is used for the generation of ATP and these complexes play a vital role in cells. Cytochrome b/b6 is a membrane protein of approximately 400 amino acid residues that probably has 8 transmembrane segments. In plants and cyanobacteria, cytochrome b6 consists of two subunits encoded by the petB and petD genes, cytochrome b/b6 non-covalently binds two heme groups, known as b562 and b566. Four conserved histidine residues are postulated to be the ligands of the atoms of these two heme groups. Cytochrome b is used as a region of mitochondrial DNA for determining phylogenetic relationships between organisms, due to its sequence variability. It is considered to be most useful in determining relationships within families, mutations in cytochrome b primarily result in exercise intolerance in human patients, though more rare, severe multi-system pathologies have also been reported. Single-point mutations in cytochrome b of Plasmodium falciparum and P. berghei are associated with resistance to the anti-malarial drug atovaquone

Lineage (evolution)
–
An evolutionary lineage is a series of organisms, populations, cells, or genes connected by a continuous line of descent from ancestor to descendent. Lineages are subsets of the tree of life. Lineages are often determined by the techniques of molecular systematics, lineages are typically visualized as subsets of a phylogenetic tree. For example, the tree in Figure 1 shows the separation of life into three ancient lineages, bacteria, archaea, and eukaryotes, thus a lineage is a single branch of the tree. Phylogenetic trees are created from DNA, RNA or protein sequence data. Apart from this, morphological differences and similarities have been, sequences from different individuals are collected and their similarity is quantified. Mathematical procedures are used to cluster individuals by similarity, just as a map is a scaled approximation of true geography, a phylogenetic tree is an approximation of the true complete evolutionary relationships. For example, in Figure 1, the lineage of animals has been collapsed to a single branch of the tree. However, this is merely a limitation of rendering space, in theory, a true and complete tree for all living organisms or for any DNA sequence could be generated

Echo parakeet
–
The echo parakeet or Mauritius parakeet, is a parrot endemic to Mauritius in the southern Indian Ocean. It is the only extant parrot of the Mascarene islands, all others have become extinct due to human activity. The extinct Réunion parakeet of Réunion was previously considered a distinct species and its scientific name change from Psittacula echo had recently found widespread approval. A wealth of circumstantial evidence nowadays suggests that the hypothesized Réunion parakeet did indeed exist, the Réunion birds were the closest relatives, and presumably conspecific, with the Mauritius ones. A study skin had been discovered at the Royal Museum of Scotland and this may be the only material proof of these birds existence, or be from Mauritius. In any case, the Réunion and Mauritius birds certainly formed a clade, until the new DNA data is available – and even then only if it would show a significant difference -, it is really a matter of opinion whether one follows a lumper or a splitter approach. Many extant or extinct birds endemic to the Mascarene Islands are derived from South Asian ancestors, including the dodo, sea levels were lower during the Pleistocene, so it was possible for species to island hop to the isolated islands. Of the about eight endemic Mascarene parrot species, all but the Mauritius parakeet have gone extinct, in spite of many of them being poorly known, fossil remains show that they shared features such as enlarged heads and jaws, reduced pectoral elements, and robust leg elements. This group may have invaded the area several times, as many of the species were so specialised that they may have diverged on hot spot islands before the Mascarenes emerged from the sea. This is surprising, due to its similarities with other Mascarene parrots that are believed to be Psittaculines. The following cladogram shows the position of the Mauritius and Réunion subspecies. 2015, However, Hume and Justin J. F. J. Jansen pointed out in 2016 that the sole specimen thought to be a Réunion parakeet has no clear provenance information and they also doubted whether the birds of Réunion and Mauritius were different species. It is generally similar to the rose-ringed parakeet—its closest living relative—except that the Mascarenes bird is a species with a markedly shorter tail. The females lack the collar, and notably possess an all-black beak. The latter feature is absent in the rose-ringed parakeet as well as the Alexandrine parakeet. The Mauritius parakeet is one of the most remarkable successes of wildlife conservation, in the early 1980s, this parakeet was almost extinct. The Mauritius parakeet seemed doomed to extinction, but with the team of Carl Jones taking over, a dedicated research and conservation effort was launched to save the birds. By the late 1980s, the situation had stabilized – though at a low level –
