Holocene
–
The Holocene is the geological epoch that began after the Pleistocene at approximately 11,700 years before present. The term Recent has often used as an exact synonym of Holocene. The Holocene is part of the Quaternary period and its name comes from the Ancient Greek words ὅλος and καινός, meaning entirely recent. It has been identified with the current warm period, known as MIS1, given these, a new term, Anthropocene, is specifically proposed and used informally only for the very latest part of modern history involving significant human impact. It is accepted by the International Commission on Stratigraphy that the Holocene started approximately 11,700 years ago, the epoch follows the Pleistocene and the last glacial period. The Holocene can be subdivided into five time intervals, or chronozones, based on climatic fluctuations, Preboreal, Boreal, Atlantic, Subboreal and they find a general correspondence across Eurasia and North America, though the method was once thought to be of no interest. The scheme was defined for Northern Europe, but the changes were claimed to occur more widely. The periods of the include a few of the final pre-Holocene oscillations of the last glacial period. Paleontologists have not defined any faunal stages for the Holocene, if subdivision is necessary, periods of human technological development, such as the Mesolithic, Neolithic, and Bronze Age, are usually used. However, the time periods referenced by these terms vary with the emergence of those technologies in different parts of the world, climatically, the Holocene may be divided evenly into the Hypsithermal and Neoglacial periods, the boundary coincides with the start of the Bronze Age in Europe. According to some scholars, a division, the Anthropocene, has now begun. Continental motions due to plate tectonics are less than a kilometre over a span of only 10,000 years, however, ice melt caused world sea levels to rise about 35 m in the early part of the Holocene. The sea level rise and temporary land depression allowed temporary marine incursions into areas that are now far from the sea, Holocene marine fossils are known, for example, from Vermont and Michigan. Other than higher-latitude temporary marine incursions associated with depression, Holocene fossils are found primarily in lakebed, floodplain. Holocene marine deposits along low-latitude coastlines are rare because the rise in sea levels during the period exceeds any likely tectonic uplift of non-glacial origin, post-glacial rebound in the Scandinavia region resulted in the formation of the Baltic Sea. The region continues to rise, still causing weak earthquakes across Northern Europe, the equivalent event in North America was the rebound of Hudson Bay, as it shrank from its larger, immediate post-glacial Tyrrell Sea phase, to near its present boundaries. Climate has been stable over the Holocene. It appears that this was influenced by the glacial ice remaining in the Northern Hemisphere until the later date

Indian chameleon
–
The Indian chameleon is a species of chameleon found in Sri Lanka, India, and other parts of South Asia. Like other chameleons, this species has a tongue, feet that are shaped into bifid claspers, a prehensile tail, independent eye movement. They move slowly with a bobbing or swaying movement and are usually arboreal, strangely, they do not choose the background colour and may not even be able to perceive colour differences. They are usually in shades of green or brown or with bands and they can change colour rapidly and the primary purpose of colour change is for communication with other chameleons and for controlling body temperature by changing to dark colours to absorb heat. They are found in India, south of the Ganges River and Chainnsa Type locality, Sri Lanka, the head has a bony casque, ornamented with crests or tubercles. A separation between the eyes, the septum, is present. Its dentition is acrodont, the teeth are compressed, triangular, the eyes are large, covered by a thick, granular lids pierced with a small central opening for the pupil. No tympanum or external ear is present, the body is compressed, and the neck is very short. The vertebrae are procoelian, abdominal ribs are present, the limbs are long, raising the body. The digits are arranged in bundles of two and three, in the hand, the bundle is formed of three, the outer of two digits, it is the reverse in the foot. The head and body are covered with granules or tubercles, no enlarged tubercles occur on the body, a feebly serrated dorsal crest is present, a series of conical tubercles form a very distinct crest along the throat and belly. Males have a process or spur, the tail is longer than head. The gular-ventral crest and the commissure of the mouth are white, from snout to vent, it is up to 7 in long, with a prehensile tail of 8 in. Barry, A. T.1936 The Common Chamaeleon in Gujarat J.

Maharashtra
–
Four Maharashtra is a state in the western region of India and is Indias second-most populous state and third-largest state by area. It is the wealthiest Indian state and it is also the worlds second-most populous sub-national entity. It has over 112 million inhabitants and its capital, Mumbai, has a population of approximately 18 million, Nagpur is Maharashtras second capital as well as its winter capital. Maharashtras business opportunities along with its potential to offer a standard of living attract migrants from all over India. Ancient and medieval Maharashtra included the empires of the Satavahana dynasty, Rashtrakuta dynasty, Western Chalukyas, Mughals, the major rivers of the state are Godavari, and Krishna. The Narmada and Tapti Rivers flow near the border between Maharashtra and Madhya Pradesh and Gujarat, Maharashtra is the second most urbanised state in India. The state has several popular Hindu places of pilgrimage including Pandharpur, Dehu and Alandi, other places that attract pilgrims from other parts of India and beyond include Hazur Sahib Gurudwara at Nanded, Sai Baba shrine at Shirdi and Dikshabhumi at Nagpur. Maharashtra is the wealthiest and one of the most developed states in India, as of 2011, the state had a per capita income of ₹1.0035 lakh, more than the national average of ₹0.73 lakh. Its GDP per capita crossed the ₹1.20 lakh threshold for the first time in 2013, however, as of 2014, the GDP per capita reduced to ₹1.03 lakh Agriculture and industries are the largest parts of the states economy. Major industries include chemical products, electrical and non-electrical machinery, textiles, petroleum, Jai Maharashtra The modern Marathi language developed from the Maharashtri Prakrit, and the word Mahratta is found in the Jain Maharashtri literature. The terms Maharashtra, Maharashtri, Marathi and Maratha may have derived from the same root, however, their exact etymology is uncertain. But the Marathas as a people do not seem to be mentioned before the thirteenth or fourteenth century, the most widely accepted theory among the linguistic scholars is that the words Maratha and Maharashtra ultimately derived from a combination of Maha and rashtrika. The word rashtrika is a Sanskritized form of Ratta, the name of a tribe or dynasty of petty chiefs ruling in the Deccan region. Another theory is that the term is derived from Maha and ratha / rathi, an alternative theory states that the term derives from the word Maha and Rashtra. However, this theory has not found acceptance among scholars who believe it to be the Sanskritised interpretation of later writers. Maharashtra was ruled by the Maurya Empire in the 4th and 3rd centuries BCE, around 230 BCE Maharashtra came under the rule of the Satavahana dynasty for 400 years. The greatest ruler of the Satavahana Dynasty was Gautamiputra Satakarni, in 90 CE Vedishri, son of the Satavahana king Satakarni, the Lord of Dakshinapatha, wielder of the unchecked wheel of Sovereignty, made Junnar, thirty miles north of Pune, the capital of his kingdom. The state was ruled by Western Satraps, Gupta Empire, Gurjara-Pratihara, Vakataka, Kadambas, Chalukya Empire, Rashtrakuta Dynasty, and Western Chalukya before finally

India
–
India, officially the Republic of India, is a country in South Asia. It is the seventh-largest country by area, the second-most populous country, and it is bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast. 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

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

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

Reptile
–
Reptiles are tetrapod animals in the class Reptilia, comprising todays turtles, crocodilians, snakes, amphisbaenians, lizards, tuatara, and their extinct relatives. The study of these traditional reptile orders, historically combined with that of amphibians, is called herpetology. Because some reptiles are more related to birds than they are to other reptiles. For this reason, many scientists prefer to consider the birds part of Reptilia as well. Some early examples include the lizard-like Hylonomus and Casineria, in addition to the living reptiles, there are many diverse groups that are now extinct, in some cases due to mass extinction events. In particular, the K–Pg extinction wiped out the pterosaurs, plesiosaurs, ornithischians, and sauropods, as well as species of theropods, crocodyliforms. Modern non-avian reptiles inhabit every continent with the exception of Antarctica, several living subgroups are recognized, Testudines, approximately 400 species, Sphenodontia,1 species, Squamata, over 9,600 species, Crocodilia,25 species, and Aves,10,000 species. Reptiles are tetrapod vertebrates, creatures that either have four limbs or, unlike amphibians, reptiles do not have an aquatic larval stage. As amniotes, reptile eggs are surrounded by membranes for protection and transport, many of the viviparous species feed their fetuses through various forms of placenta analogous to those of mammals, with some providing initial care for their hatchlings. In the 18th century, the reptiles were, from the outset of classification, the terms reptile and amphibian were largely interchangeable, reptile being preferred by the French. Josephus Nicolaus Laurenti was the first to use the term Reptilia for an expanded selection of reptiles. Today, the two groups are commonly treated under the same heading as herptiles. He subsequently proposed the names of Sauropsida and Ichthyopsida for the two groups. In 1866, Haeckel demonstrated that vertebrates could be divided based on their strategies, and that reptiles, birds. The terms Sauropsida and Theropsida were used again in 1916 by E. S, Goodrich to distinguish between lizards, birds, and their relatives on the one hand and mammals and their extinct relatives on the other. Goodrich supported this division by the nature of the hearts and blood vessels in each group, according to Goodrich, both lineages evolved from an earlier stem group, Protosauria in which he included some animals today considered reptile-like amphibians, as well as early reptiles. Watson observed that the first two groups diverged very early in history, so he divided Goodrichs Protosauria between them. He also reinterpreted Sauropsida and Theropsida to exclude birds and mammals, thus his Sauropsida included Procolophonia, Eosuchia, Millerosauria, Chelonia, Squamata, Rhynchocephalia, Crocodilia, thecodonts, non-avian dinosaurs, pterosaurs, ichthyosaurs, and sauropterygians

Squamata
–
The Squamata, or the scaled reptiles, are the largest recent order of reptiles, comprising all lizards and snakes. With over 10,000 species, it is also the second-largest order of extant vertebrates, after the perciform fish, members of the order are distinguished by their skins, which bear horny scales or shields. They also possess movable quadrate bones, making it possible to move the upper jaw relative to the neurocranium and this is particularly visible in snakes, which are able to open their mouths very wide to accommodate comparatively large prey. They are the most variably sized order of reptiles, ranging from the 16 mm dwarf gecko to the 5.21 m green anaconda and the now-extinct mosasaurs, among the other reptiles, squamates are most closely related to the tuatara, which strongly resembles lizards. Squamates are a sister group to the tuatara. The squamates and tuatara together are a group to crocodiles and birds. Fossils of the sister group, the Rhynchocephalia, appear in the Early Triassic. Also appearing in the Cretaceous are the polyglyphanodonts, a group of uncertain affinities, and the mosasaurs. At the end of the Cretaceous, squamates suffered a major extinction at the K-T boundary which wiped out polyglyphanodonts, mosasaurs, the relationships of squamates have been debated. From morphological data, the iguanians were long thought to be the most ancient branch of the tree, however, iguanians are now united with snakes and anguimorphs in a group called the Toxicofera. DNA also suggests that the various limbless groups- snakes, amphisbaenians, and dibamids- are unrelated, the male members of the group Squamata have hemipenes, which are usually held inverted within their bodies, and are everted for reproduction via erectile tissue like that in the human penis. Only one is used at a time, and some evidence indicates that males alternate use between copulations, the hemipenis has a variety of shapes, depending on the species. Often it bears spines or hooks, to anchor the male within the female, some species even have forked hemipenes. Due to being everted and inverted, hemipenes do not have a completely enclosed channel for the conduction of sperm and this is also the only reptile group in which both viviparous and ovoviviparous species are found, as well as the usual oviparous reptiles. Some species, such as the Komodo dragon, can reproduce asexually through parthenogenesis. There have been studies on how sexual selection manifests itself in snakes, snakes use a variety of tactics in acquiring mates. It is common for neck biting to occur while the snakes are entwined, parthenogenesis is a natural form of reproduction in which growth and development of embryos occur without fertilization. Agkistrodon contortrix and Agkistrodon piscivorus can reproduce by facultative parthenogenesis and that is, they are capable of switching from a sexual mode of reproduction to an asexual mode

Iguania
–
The Iguania are a suborder of the Squamata that contains the iguanas, chameleons, agamids, and New World lizards, such as anoles and phrynosomatids. Using morphological features as a guide to evolutionary relationships, the Iguania are believed to form the group to the remainder of the Squamata. However, molecular information has placed Iguania well within the Squamata as sister taxa to the Anguimorpha, iguanians are largely arboreal and have primitively fleshy, nonprehensile tongues, although the condition is highly modified in chameleons. The group has a record that extends back to the Early Jurassic. Showing the interrelationships of extinct and living iguanians

Constantine Samuel Rafinesque
–
Constantine Samuel Rafinesque-Schmaltz, as he is known in Europe, was a nineteenth-century polymath born near Constantinople in the Ottoman Empire and self-educated in France. He traveled as a man in the United States, ultimately settling in Ohio in 1815, where he made notable contributions to botany, zoology. He also contributed to the study of ancient Mesoamerican linguistics, in addition to work he had completed in Europe. Rafinesque was eccentric, and is portrayed as an erratic genius. He was an autodidact who excelled in fields of knowledge, as a zoologist, botanist, writer. He wrote prolifically on such topics as anthropology, biology, geology, and linguistics. Today, scholars agree that he was far ahead of his time in many areas, among his theories was that ancestors of Native Americans had migrated by the Bering Sea from Asia to North America. Rafinesque was born on October 22,1783 in Galata, a suburb of Constantinople and his father F. G. Rafinesque was a French merchant from Marseilles, his mother M. Schmaltz was of German descent and born in Constantinople. His father died in Philadelphia about 1793, Rafinesque spent his youth in Marseilles, and was mostly self-educated, he never attended university. By the age of twelve, he had begun collecting plants for a herbarium, by fourteen, he taught himself perfect Greek and Latin because he needed to follow footnotes in the books he was reading in his paternal grandmothers libraries. In 1802, at the age of nineteen, Rafinesque sailed to Philadelphia in the United States with his younger brother and they traveled through Pennsylvania and Delaware, where he made the acquaintance of most of the young nations few botanists. In 1805 Rafinesque returned to Europe with his collection of specimens, and settled in Palermo, Sicily. He became so successful in trade that he retired by age twenty-five, for a time Rafinesque also worked as secretary to the American consul. During his stay in Sicily, he studied plants and fishes and he was elected a Fellow of the American Academy of Arts and Sciences in 1808. After their son died in 1815, he left her and returned to the United States, when his ship Union foundered near the coast of Connecticut, he lost all his books and all his specimens. Settling in New York, Rafinesque became a member of the newly established Lyceum of Natural History. In 1817 his book Florula Ludoviciana or A Flora of the State of Louisiana was strongly criticized by fellow botanists, by 1818, he had collected and named more than 250 new species of plants and animals. Slowly he was rebuilding his collection of objects from nature, in 1819 Rafinesque became professor of botany at Transylvania University in Lexington, Kentucky, where he also gave private lessons in French, Italian and Spanish

Brookesiinae
–
The Family Chamaeleonidae was divided into two subfamilies, Brookesiinae and Chamaeleoninae, by Klaver and Böhme in 1986. Under this classification, Brookesiinae included the genera Brookesia and Rhampholeon, the Brookesiinae are small, often brown in colour, and occur in central Africa and Madagascar. They have terrestrial habits, or may be found in the levels of shrubs. In 2015, however, Glaw reworked the subfamilial division by placing only the genera Brookesia and Palleon within the Brookesiinae subfamily, the two genera currently included in the subfamily are, Subfamily Brookesiinae Genus Brookesia Genus Palleon ITIS

Brookesia is a genus of chameleons endemic to Madagascar, that range from small to very small in size, and are known collectively as leaf chameleons. Brookesia includes species considered to be the worlds smallest chameleons which are also among the smallest reptiles, members of the genus Brookesia are largely brown and most are essentially terrestrial. Most inhabit very small ranges in areas that are difficult to access, the generic name Brookesia is in honor of British naturalist Joshua Brookes. Most Brookesia are on CITES Appendix II, the exception being B. perarmata on Appendix I. Consequently, a permit is required to import any of the below species from their native Madagascar.

Bradypodion
–
Bradypodion is one of six genera of chameleons within the true or typical chameleons. They are native to southern Africa, and are collectively called South African dwarf chameleons. Some other small chameleons from eastern and central Africa are occasionally placed herein, see also Systematics below and Kinyongia and Nadzikambia. Delimitation of Bradypodion has been controversial for some time, alternatively, many of the present species were reduced to subspecies status. This has since been refuted, but several more species seem recognizable judging from morphological and mitochondrial 16S rRNA, the phylogeny and biogeography of this group is quite consistently resolved. They occur in isolated ranges in coastal Western Cape and western Eastern Cape provinces, inhabiting a wide range of habitats, they are large, and have brilliant, predominantly green coloration and long tails - just as in many Chamaeleo. These characters are plesiomorphic, retained from the genus ancestor, the remaining species form a well-supported clade, which in turn can be divided into smaller groups. These are also plesiomorphic in habitus and habits, another group of taxa occurs from easternmost Eastern Cape to central KwaZulu-Natal provinces, between Gilboa Forest and the Tugela River. These appear to be a recent radiation from a single ancestor, and the group requires more research as regards species limits. Several largish but short-tailed and cryptic taxa inhabit more arid habitats such as karoo, the Karroo and southern dwarf chameleons seem to have considerable gene flow range from Northern Cape to coastal Eastern Cape provinces. The small and nearly extinct Smiths dwarf chameleon is close to these, the last species with aridland apomorphies, the Namaqua dwarf chameleon, is quite distant to the others, it occurs in coastal regions from north of the Cape species through Namaqualand. This is probably still a part of a radiation which brought about all the aridland taxa. The remaining species are all small inhabitants of forested slopes and fynbos, such as the black-headed, however, as already indicated by the distinctness of these two, their morphologies seem to be a convergent adaptation. The Kentani and Transkei dwarf chameleons from the east coasts of Eastern Cape may or may not be each others closest relatives, setaros dwarf chameleon from northeastern coastal KwaZulu-Natal is not close to these. In conclusion, of the three basic morphotypes found in genus, one is plesiomorphic, another apparently only evolved once. The ancestors of Bradypodion thus were mid-sized chameleons with vivid color, the aridland habitat fluctuates in extent during climate shifts, and mountainous habitat becomes fragmented or consolidates accordingly.

Chamaeleo
–
They are slow moving with independently movable eyes, the ability to change skin colouration, long tongue, usually a prehensile tail, and special leg adaptations for grasping vegetation. Males are generally larger and more colorful than females, almost all species have a maximum snout-vent length between 15 and 40 centimetres. The vast majority are arboreal and typically found in trees or bushes, the genus includes only oviparous species. With few exceptions, the chameleons most commonly seen in captivity are all members of Chamaeleo, notably the common, Senegal and veiled chameleons, Chamaeleo is the type genus of the family Chamaeleonidae. All other genera of the subfamily Chamaeleoninae have at some point been included in the genus Chamaeleo,14 species are recognized as being valid, and subspecies are recognized for some species. M.

Kinyongia
–
Kinyongia is a chameleon genus recently established for several plesiomorphic species found in forest and woodland in Kenya, Tanzania, Uganda, Rwanda, and far eastern DR Congo. All except K. adolfifriderici and K. tavetana are restricted to highlands, in most, at least the males have horns or knobs on their noses. They were erroneously placed into Bradypodion for some time and it has recently been pointed out that the ending to the specific epithet in several of the below listed species should be modified to match the feminine genus name.

Rieppeleon
–
Rieppeleon is a genus of small, typically brown chameleons found in forests and savannas in central East Africa. They are found at low levels in bushes, or on the ground among grass or leaf litter, the genus Rieppeleon was named after Swiss-born American herpetologist Olivier Rieppel. The specific name, kerstenii, is in honor of German chemist, the subspecific name, robecchii, is in honor of Italian geologist and explorer Luigi Robecchi Bricchetti. Until recently, the species in the genus Rieppeleon were commonly included in the genus Rhampholeon instead, the following species and subspecies are recognized as being valid.

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
25.
Clade
–
A clade is a group of organisms that consists of a common ancestor and all its lineal descendants, and represents a single branch on the tree of life. The common ancestor may be an individual, a population, a species, clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently, over the last few decades, the cladistic approach has revolutionized biological classification and revealed surprising evolutionary relationships among organisms. Increasingly, taxonomists try to avoid naming taxa that are not clades, the term clade was coined in 1957 by the biologist Julian Huxley to refer to the result of cladogenesis, a concept Huxley borrowed from Bernhard Rensch. Many commonly named groups are clades, for example, rodents or insects, because in each case, their name refers to a common ancestor with all its descendant branches. Rodents, for example, are a branch of mammals that split off after the end of the period when the clade Dinosauria stopped being the dominant terrestrial vertebrates 66 million years ago, the original population and all its descendants are a clade. The rodent clade corresponds to the order Rodentia, and insects to the class Insecta and these clades include smaller clades, such as chipmunk or ant, each of which consists of even smaller clades. The clade rodent is in included in the mammal, vertebrate. The phenomenon of convergent evolution is, however, responsible for cases where there are misleading similarities in the morphology of groups that evolved from different lineages. The publication of Darwins theory of evolution in 1859 gave this view increasing weight, thomas Henry Huxley, an early advocate of evolutionary theory, proposed a revised taxonomy based on clades. For example, he grouped birds with reptiles, based on fossil evidence, german biologist Emil Hans Willi Hennig is considered to be the founder of cladistics. Taxonomists have increasingly worked to make the taxonomic system reflect evolution, when it comes to naming, however, this principle is not always compatible with the traditional rank-based nomenclature. For these and other reasons, phylogenetic nomenclature has been developed, a clade is by definition monophyletic, meaning that it contains one ancestor and all its descendants. The ancestor can be known or unknown, any and all members of a clade can be extant or extinct, the science that tries to reconstruct phylogenetic trees and thus discover clades is called phylogenetics or cladistics, the latter term coined by Ernst Mayr, derived from clade. The results of analyses are tree-shaped diagrams called cladograms, they. Three methods of defining clades are featured in phylogenetic nomenclature, node-, stem-, the relationship between clades can be described in several ways, A clade located within a clade is said to be nested within that clade. In the diagram, the clade, i. e. the apes. Two clades are sisters if they have a common ancestor

Old World
–
The Old World consists of Africa, Europe, and Asia, regarded collectively as the part of the world known to Europeans before contact with the Americas. It is used in the context of, and contrast with and these regions were connected via the Silk Road trade route, and they have a pronounced Iron Age period following the Bronze Age. The concept of the three continents in the Old World, viz. Asia, Africa, and Europe, goes back to classical antiquity and their boundaries as defined by Ptolemy and other geographers of antiquity were drawn along the Nile and Don rivers. This definition remained influential throughout the Middle Ages and the Early Modern period, the Old world has areas of North Africa, Eurasia, parts of Papua New Guinea and Solomon Islands. The mainland of Afro-Eurasia has been referred to as the World Island, the term may have been coined by Sir Halford John Mackinder in The Geographical Pivot of History. The equivalent of the Old World had names in some of its ancient cultures, including Midgard in Germanic cosmology, synoptic table of the principal old world prehistoric cultures Afro-Eurasia

Lizard
–
Lizards are a widespread group of squamate reptiles, with over 6,000 species, ranging across all continents except Antarctica, as well as most oceanic island chains. The group is paraphyletic as it excludes the snakes which are also squamates, Lizards typically have four legs feet and external ears, though some are legless, while snakes lack both of these characteristics. Lizards and snakes share a movable quadrate bone, distinguishing them from the sphenodonts, Lizards form about 60% of all the species of extant non-avian reptiles. Some extinct varanids reached great size, The giant monitor Megalania is estimated to have reached up to 7 m long, vision, including color vision, is particularly well developed in most lizards. Most lizards communicate using body language, using specific postures, gestures, and movements to define territory, resolve disputes, some species of lizards also use pheromones or bright colors, such as the iridescent patches on the belly of Sceloporus. These colors are visible to predators, so are often hidden on the underside or between scales and only revealed when necessary. The particular innovation in this respect is the dewlap, a colored patch of skin on the throat. When a display is needed, a lizard can erect the hyoid bone of its throat, anoles are particularly famous for this display, with each species having specific colors, including patterns only visible under ultraviolet light, as many lizards can see UV light. Lizard tails are often a different and dramatically more vivid color than the rest of the body so as to potential predators to strike for the tail first. Many lizards, including geckos and skinks, are capable of shedding part of their tails through a process called autotomy. This is an example of the pars pro toto principle, sacrificing a part for the whole, the detached tail writhes and wiggles, creating a deceptive sense of continued struggle, distracting the predators attention from the fleeing prey animal. The lizard partially regenerates its tail over a period of weeks, a 2014 research identified 326 genes involved in the regeneration of lizard tails. The new section contains cartilage rather than bone, and the skin may be discolored compared to the rest of the body, most lizards are oviparous, though in some species the eggs are retained until the live young emerge. Parthenogenesis occurs in at least 50 species and may be more widespread in the group. Sexual selection in lizards shows evidence of mate choice, favouring males display fitness indicators. However, doubt has been raised over the age of Tikiguania because it is almost indistinguishable from modern agamid lizards, the Tikiguania remains may instead be late Tertiary or Quaternary in age, having been washed into much older Triassic sediments. Lizards are most closely related to the Rhynchocephalia, which appeared in the Late Triassic, mitochondrial phylogenetics suggest that the first lizards evolved in the late Permian. It had been thought on the basis of data that iguanid lizards diverged from other squamates very early on
28.
Dactyly
–
In biology, dactyly is the arrangement of digits on the hands, feet, or sometimes wings of a tetrapod animal. It comes from the Greek word δακτυλος = finger, sometimes the ending -dactylia is used. The derived adjectives end with -dactyl or -dactylous, pentadactyly is the condition of having five digits on each limb. However, this viewpoint was challenged by Stephen Jay Gould in his 1991 essay Eight Little Piggies, despite the individual variations listed below, the relationship is to the original five-digit model. In reptiles, the limbs are pentadactylous, tetradactyly is the condition of having four digits on a limb, as in many amphibians, birds, and theropod dinosaurs. Cartoon characters are drawn with four digits on each hand/foot as its clearer to see than five. Tridactyly is the condition of having three digits on a limb, as in the rhinoceros and ancestors of the such as Protohippus. These all belong to the Perissodactyla, some birds also have three toes, including emus, bustards, and quail. Didactyly or bidactyly is the condition of having two digits on each limb, as in the Hypertragulidae and two-toed sloth, Choloepus didactylus. In humans this name is used for an abnormality in which the digits are missing, leaving only the thumb and fifth finger, or big. Cloven-hoofed mammals have two digits, as do ostriches. Monodactyly is the condition of having a single digit on a limb, syndactyly is a condition where two or more digits are fused together. It occurs normally in some mammals, such as the siamang and it occurs as an unusual condition in humans. Polydactyly is when a limb has more than the number of digits. This can be, As a result of abnormality in a normally pentadactyl animal. Polydactyly is very common among domestic cats and it also occurs secondarily in some later tetrapods, such as ichthyosaurs. Oligodactyly is having too few digits when not caused by an amputation and it is sometimes incorrectly called hypodactyly or confused with aphalangia, the absence of the phalanx bone on one or more digits. When all the digits on a hand or foot are absent, ectrodactyly, also known as split-hand malformation, is the congenital absence of one or more central digits of the hands and feet
29.
Prehensility
–
Prehensility is the quality of an appendage or organ that has adapted for grasping or holding. The word is derived from the Latin term prehendere, meaning to grasp, seahorses grip seaweed with their tails. Several fossil animals have been interpreted as having prehensile tails, including several Late Triassic drepanosaurs, prehensility affords animals a great natural advantage in manipulating their environment for feeding, digging and defense. It enables many animals, such as primates, to use tools to complete tasks that would otherwise be impossible without highly specialized anatomy, for example, chimpanzees have the ability to use sticks to obtain termites and grubs in a manner similar to human fishing. However, not all prehensile organs are applied to tool use, the giraffe tongue, for instance, is instead used in feeding and self-cleaning
30.
Stereopsis
–
Because the eyes of humans, and many animals, are located at different lateral positions on the head, binocular vision results in two slightly different images projected to the retinas of the eyes. The differences are mainly in the horizontal position of objects in the two images. These positional differences are referred to as horizontal disparities or, more generally, disparities are processed in the visual cortex of the brain to yield depth perception. The perception of depth in such cases is referred to as stereoscopic depth. Therefore, the term stereopsis can also specifically to the unique impression of depth associated with binocular vision. There are two aspects to stereopsis, coarse stereopsis and fine stereopsis, and provide depth information of different degree of spatial and temporal precision. Coarse stereopsis appears to be used to judge stereoscopic motion in the periphery and it provides the sense of being immersed in ones surroundings and is therefore sometimes also referred to as qualitative stereopsis. Coarse stereopsis is important for orientation in space while moving, for example when descending a flight of stairs, fine stereopsis is mainly based on static differences. It allows the individual to determine the depth of objects in the visual area and is therefore also called quantitative stereopsis. Fine stereopsis is important for fine-motorical tasks such as threading a needle, the stereopsis which an individual can achieve is limited by the level of visual acuity of the poorer eye. In particular, patients who have comparatively lower visual acuity tend to need relatively larger spatial frequencies to be present in the input images, else they cannot achieve stereopsis. Fine stereopsis requires both eyes to have a visual acuity in order to detect small spatial differences, and is easily disrupted by early visual deprivation. Furthermore, there are indications that coarse stereopsis is the mechanism that keeps the two eyes aligned after strabismus surgery and it has also been suggested to distinguish between two different types of stereoscopic depth perception, static depth perception and motion-in-depth perception. Some individuals who have strabismus and show no depth perception using static stereotests do perceive motion in depth when tested using dynamic random dot stereograms, one study found the combination of motion stereopsis and no static stereopsis to be present only in exotropes, not in esotropes. There are strong indications that the stereoscopic mechanism consists of at least two mechanisms, possibly three. The coarse stereoscopic system seems to be able to provide residual binocular depth information in some individuals who lack fine stereopsis, individuals have been found to integrate the various stimuli, for example stereoscopic cues and motion occlusion, in different ways. Not everyone has the ability to see using stereopsis. Stereopsis has an impact on exercising practical tasks such as needle-threading, ball-catching, pouring liquids

Rainforest
–
The monsoon trough, alternatively known as the intertropical convergence zone, plays a significant role in creating the climatic conditions necessary for the Earths tropical rainforests. Around 40% to 75% of all species are indigenous to the rainforests. It has been estimated there may be many millions of species of plants, insects. Tropical rainforests have been called the jewels of the Earth and the worlds largest pharmacy, the undergrowth in some areas of a rainforest can be restricted by poor penetration of sunlight to ground level. If the leaf canopy is destroyed or thinned, the ground beneath is soon colonized by a dense, tangled growth of vines, shrubs and small trees, the term jungle is also sometimes applied to tropical rainforests generally. Tropical rainforests are characterized by a warm and wet climate with no dry season. Mean monthly temperatures exceed 18 °C during all months of the year, average annual rainfall is no less than 168 cm and can exceed 1,000 cm although it typically lies between 175 cm and 200 cm. Many of the tropical forests are associated with the location of the monsoon trough. The broader category of tropical moist forests are located in the zone between the Tropic of Cancer and Tropic of Capricorn. Tropical forests have been called the Earths lungs, although it is now known that rainforests contribute little net oxygen addition to the atmosphere through photosynthesis, Tropical forests cover a large part of the globe, but temperate rainforests only occur in few regions around the world. Temperate rainforests are rainforests in temperate regions and they occur in North America, in Europe, in East Asia, in South America and also in Australia and New Zealand. A tropical rainforest typically has a number of layers, each with different plants, examples include the emergent, canopy, understorey and forest floor layers. They need to be able to withstand the hot temperatures and strong winds that occur above the canopy in some areas, eagles, butterflies, bats and certain monkeys inhabit this layer. The canopy layer contains the majority of the largest trees, typically 30 metres to 45 metres tall, the densest areas of biodiversity are found in the forest canopy, a more or less continuous cover of foliage formed by adjacent treetops. The canopy, by some estimates, is home to 50 percent of all plant species, epiphytic plants attach to trunks and branches, and obtain water and minerals from rain and debris that collects on the supporting plants. The fauna is similar to found in the emergent layer. A quarter of all species are believed to exist in the rainforest canopy. Scientists have long suspected the richness of the canopy as a habitat, true exploration of this habitat only began in the 1980s, when scientists developed methods to reach the canopy, such as firing ropes into the trees using crossbows
32.
Desert
–
A desert is a barren area of land where little precipitation occurs and consequently living conditions are hostile for plant and animal life. The lack of vegetation exposes the unprotected surface of the ground to the processes of denudation, about one third of the land surface of the world is arid or semi-arid. This includes much of the regions where little precipitation occurs. Deserts can be classified by the amount of precipitation falls, by the temperature that prevails. Deserts are formed by weathering processes as large variations in temperature between day and night put strains on the rocks which consequently break in pieces, although rain seldom occurs in deserts, there are occasional downpours that can result in flash floods. Rain falling on hot rocks can cause them to shatter and the resulting fragments and this picks up particles of sand and dust and wafts them aloft in sand or dust storms. Wind-blown sand grains striking any solid object in their path can abrade the surface, rocks are smoothed down, and the wind sorts sand into uniform deposits. The grains end up as level sheets of sand or are piled high in billowing sand dunes, other deserts are flat, stony plains where all the fine material has been blown away and the surface consists of a mosaic of smooth stones. These areas are known as desert pavements and little further erosion takes place, other desert features include rock outcrops, exposed bedrock and clays once deposited by flowing water. Temporary lakes may form and salt pans may be left when waters evaporate, there may be underground sources of water in the form of springs and seepages from aquifers. Where these are found, oases can occur, plants and animals living in the desert need special adaptations to survive in the harsh environment. Plants tend to be tough and wiry with small or no leaves, water-resistant cuticles, some annual plants germinate, bloom and die in the course of a few weeks after rainfall while other long-lived plants survive for years and have deep root systems able to tap underground moisture. Animals need to cool and find enough food and water to survive. Many are nocturnal and stay in the shade or underground during the heat of the day and they tend to be efficient at conserving water, extracting most of their needs from their food and concentrating their urine. Some animals remain in a state of dormancy for long periods and they then reproduce rapidly while conditions are favorable before returning to dormancy. People have struggled to live in deserts and the surrounding lands for millennia. Nomads have moved their flocks and herds to wherever grazing is available, the cultivation of semi-arid regions encourages erosion of soil and is one of the causes of increased desertification. Many trade routes have been forged across deserts, especially across the Sahara Desert, large numbers of slaves were also taken northwards across the Sahara

Madagascar
–
Madagascar, officially the Republic of Madagascar, and previously known as the Malagasy Republic, is an island country in the Indian Ocean, off the coast of Southeast Africa. The nation comprises the island of Madagascar, and numerous smaller peripheral islands, consequently, Madagascar is a biodiversity hotspot, over 90% of its wildlife is found nowhere else on Earth. The islands diverse ecosystems and unique wildlife are threatened by the encroachment of the growing human population. The first archaeological evidence for human foraging on Madagascar dates to 2000 BC, human settlement of Madagascar occurred between 350 BC and AD550 by Austronesian peoples arriving on outrigger canoes from Borneo. These were joined around AD1000 by Bantu migrants crossing the Mozambique Channel from East Africa, other groups continued to settle on Madagascar over time, each one making lasting contributions to Malagasy cultural life. The Malagasy ethnic group is divided into 18 or more sub-groups of which the largest are the Merina of the central highlands. Until the late 18th century, the island of Madagascar was ruled by an assortment of shifting sociopolitical alliances. Beginning in the early 19th century, most of the island was united and ruled as the Kingdom of Madagascar by a series of Merina nobles, the monarchy collapsed in 1897 when the island was absorbed into the French colonial empire, from which the island gained independence in 1960. The autonomous state of Madagascar has since undergone four major constitutional periods, since 1992, the nation has officially been governed as a constitutional democracy from its capital at Antananarivo. However, in an uprising in 2009, president Marc Ravalomanana was made to resign. Constitutional governance was restored in January 2014, when Hery Rajaonarimampianina was named president following a 2013 election deemed fair, Madagascar is a member of the United Nations, the Organisation Internationale de la Francophonie and the Southern African Development Community. Madagascar belongs to the group of least developed countries, according to the United Nations, Malagasy and French are both official languages of the state. The majority of the population adheres to traditional beliefs, Christianity, ecotourism and agriculture, paired with greater investments in education, health, and private enterprise, are key elements of Madagascars development strategy. As of 2017, the economy has been weakened by the 2009-2013 political crisis, in the Malagasy language, the island of Madagascar is called Madagasikara and its people are referred to as Malagasy. The islands appellation Madagascar is not of origin, but rather was popularized in the Middle Ages by Europeans. On St. Laurences Day in 1500, Portuguese explorer Diogo Dias landed on the island, polos name was preferred and popularized on Renaissance maps. At 592,800 square kilometres, Madagascar is the worlds 47th largest country, the country lies mostly between latitudes 12°S and 26°S, and longitudes 43°E and 51°E. Neighboring islands include the French territory of Réunion and the country of Mauritius to the east, as well as the state of Comoros, the nearest mainland state is Mozambique, located to the west

Sri Lanka
–
Sri Lanka, officially the Democratic Socialist Republic of Sri Lanka, is an island country in South Asia near south-east India. Sri Lanka has maritime borders with India to the northwest and the Maldives to the southwest, Sri Lankas documented history spans 3,000 years, with evidence of pre-historic human settlements dating back to at least 125,000 years. Its geographic location and deep harbours made it of strategic importance from the time of the ancient Silk Road through to World War II. Sri Lanka was known from the beginning of British colonial rule until 1972 as Ceylon, Sri Lankas recent history has been marred by a thirty-year civil war which decisively ended when the Sri Lankan military defeated the Liberation Tigers of Tamil Eelam in 2009. A diverse and multicultural country, Sri Lanka is home to many religions, ethnic groups, in addition to the majority Sinhalese, it is home to large groups of Sri Lankan and Indian Tamils, Moors, Burghers, Malays, Kaffirs and the aboriginal Vedda. Sri Lanka has a rich Buddhist heritage, and the first known Buddhist writings of Sri Lanka, Sri Lanka is a republic and a unitary state governed by a semi-presidential system. The legislative capital, Sri Jayawardenepura Kotte, is a suburb of the capital and largest city. Along with the Maldives, Sri Lanka is one of the two countries in South Asia that are rated among high human development on the Human Development Index. In antiquity, Sri Lanka was known to travellers by a variety of names, according to the Mahavamsa, the legendary Prince Vijaya named the land Tambapanni, because his followers hands were reddened by the red soil of the area. In Hindu mythology, such as the Mahabharata, the island was referred to as Lankā, in Tamil, the island is referred to as Eelam. Ancient Greek geographers called it Taprobanā or Taprobanē from the word Tambapanni, as a British crown colony, the island was known as Ceylon, it achieved independence as the Dominion of Ceylon in 1948. The country is known in Sinhalese as Śrī Laṃkā and in Tamil as Ilaṅkai, in 1972, its formal name was changed to Free, Sovereign and Independent Republic of Sri Lanka. Later in 1978 it was changed to the Democratic Socialist Republic of Sri Lanka, as the name Ceylon still appears in the names of a number of organisations, the Sri Lankan government announced in 2011 a plan to rename all those over which it has authority. The pre-history of Sri Lanka goes back 125,000 years, the era spans the Palaeolithic, Mesolithic and early Iron Ages. Among the Paleolithic human settlements discovered in Sri Lanka, Pahiyangala and it is said that Kubera was overthrown by his demon stepbrother Ravana, the powerful emperor who built a mythical flying machine named Dandu Monara. The modern city of Wariyapola is described as Ravanas airport, early inhabitants of Sri Lanka were probably ancestors of the Vedda people, an indigenous people numbering approximately 2,500 living in modern-day Sri Lanka. According to the Mahāvamsa, a written in Pāḷi, the original inhabitants of Sri Lanka are the Yakshas and Nagas. Ancient cemeteries that were used before 600BC and other signs of advanced civilization has also discovered in Sri Lanka

Introduced species
–
Non-native species can have various effects on the local ecosystem. Introduced species that become established and spread beyond the place of introduction are called invasive species, some have a negative effect on a local ecosystem. Some introduced species may have no effect or only minor impact. Some species have been introduced intentionally to combat pests and they are called biocontrols and may be regarded as beneficial as an alternative to pesticides in agriculture for example. In some instances the potential for being beneficial or detrimental in the long run remains unknown, a list of some introduced species is given in a separate article. The effects of introduced species on natural environments have gained much scrutiny from scientists, governments, the terminology associated with introduced species is now in flux for various reasons. The term invasive refers only to those species that become established, for practical purposes, this term is applied only to invasive species that cause damage. With respect to plants, these latter are in this case defined as either ornamental or cultivated plants, also called an exotic or non-native species. Such species might be termed naturalized, established, wild non-native species, if they further spread beyond the place of introduction they are called invasive. The transition from introduction, to establishment and to invasion has been described in the context of plants, introduced species are essentially non-native species. Invasive species are introduced species that spreadwidely or quickly and cause harm, be that to the environment, human health. There have been calls from scientists to consider a species only in terms of their spread. According to a definition, an invasive species is one that has been introduced and become a pest in its new location. The term is used to both a sense of urgency and actual or potential harm. Executive Order 13112 defines invasive species as a species whose introduction does or is likely to cause economic or environmental harm or harm to human health. The biological definition of species, on the other hand, makes no reference to the harm they may cause. From a regulatory perspective, it is neither desirable nor practical to list as undesirable or outright ban all non-native species, regulations require a definitional distinction between non-natives that are deemed especially onerous and all others. Introduced pest species that are listed as invasive, best fit the definition of an invasive species

Hawaii
–
Hawaii is the 50th and most recent state to have joined the United States of America, having received statehood on August 21,1959. Hawaii is the only U. S. state located in Oceania and it is the northernmost island group in Polynesia, occupying most of an archipelago in the central Pacific Ocean. Hawaii is the only U. S. state not located in the Americas, the state encompasses nearly the entire volcanic Hawaiian archipelago, which comprises hundreds of islands spread over 1,500 miles. At the southeastern end of the archipelago, the eight main islands are—in order from northwest to southeast, Niʻihau, Kauaʻi, Oʻahu, Molokaʻi, Lānaʻi, Kahoʻolawe, Maui, and the Island of Hawaiʻi. The last is the largest island in the group, it is called the Big Island or Hawaiʻi Island to avoid confusion with the state or archipelago. The archipelago is physiographically and ethnologically part of the Polynesian subregion of Oceania, Hawaii has over a million permanent residents, along with many visitors and U. S. military personnel. Its capital is Honolulu on the island of Oʻahu, Hawaii is the 8th-smallest and the 11th-least populous, but the 13th-most densely populated of the fifty U. S. states. It is the state with an Asian plurality. The states coastline is about 750 miles long, the fourth longest in the U. S. after the coastlines of Alaska, Florida, the state of Hawaii derives its name from the name of its largest island, Hawaiʻi. A common Hawaiian explanation of the name of Hawaiʻi is that was named for Hawaiʻiloa and he is said to have discovered the islands when they were first settled. The Hawaiian language word Hawaiʻi is very similar to Proto-Polynesian *Sawaiki, cognates of Hawaiʻi are found in other Polynesian languages, including Māori, Rarotongan and Samoan. According to linguists Pukui and Elbert, lsewhere in Polynesia, Hawaiʻi or a cognate is the name of the underworld or of the home, but in Hawaii. A somewhat divisive political issue arose in 1978 when the Constitution of the State of Hawaii added Hawaiian as an official state language. The title of the constitution is The Constitution of the State of Hawaii. Article XV, Section 1 of the Constitution uses The State of Hawaii, diacritics were not used because the document, drafted in 1949, predates the use of the okina and the kahakō in modern Hawaiian orthography. The exact spelling of the name in the Hawaiian language is Hawaiʻi. In the Hawaii Admission Act that granted Hawaiian statehood, the government recognized Hawaii as the official state name. Official government publications, department and office titles, and the Seal of Hawaii use the spelling with no symbols for glottal stops or vowel length

California
–
California is the most populous state in the United States and the third most extensive by area. Located on the western coast of the U. S, California is bordered by the other U. S. states of Oregon, Nevada, and Arizona and shares an international border with the Mexican state of Baja California. Los Angeles is Californias most populous city, and the second largest after New York City. The Los Angeles Area and the San Francisco Bay Area are the nations second- and fifth-most populous urban regions, California also has the nations most populous county, Los Angeles County, and its largest county by area, San Bernardino County. The Central Valley, an agricultural area, dominates the states center. What is now California was first settled by various Native American tribes before being explored by a number of European expeditions during the 16th and 17th centuries, the Spanish Empire then claimed it as part of Alta California in their New Spain colony. The area became a part of Mexico in 1821 following its war for independence. The western portion of Alta California then was organized as the State of California, the California Gold Rush starting in 1848 led to dramatic social and demographic changes, with large-scale emigration from the east and abroad with an accompanying economic boom. If it were a country, California would be the 6th largest economy in the world, fifty-eight percent of the states economy is centered on finance, government, real estate services, technology, and professional, scientific and technical business services. Although it accounts for only 1.5 percent of the states economy, the story of Calafia is recorded in a 1510 work The Adventures of Esplandián, written as a sequel to Amadis de Gaula by Spanish adventure writer Garci Rodríguez de Montalvo. The kingdom of Queen Calafia, according to Montalvo, was said to be a land inhabited by griffins and other strange beasts. This conventional wisdom that California was an island, with maps drawn to reflect this belief, shortened forms of the states name include CA, Cal. Calif. and US-CA. Settled by successive waves of arrivals during the last 10,000 years, various estimates of the native population range from 100,000 to 300,000. The Indigenous peoples of California included more than 70 distinct groups of Native Americans, ranging from large, settled populations living on the coast to groups in the interior. California groups also were diverse in their organization with bands, tribes, villages. Trade, intermarriage and military alliances fostered many social and economic relationships among the diverse groups, the first European effort to explore the coast as far north as the Russian River was a Spanish sailing expedition, led by Portuguese captain Juan Rodríguez Cabrillo, in 1542. Some 37 years later English explorer Francis Drake also explored and claimed a portion of the California coast in 1579. Spanish traders made unintended visits with the Manila galleons on their trips from the Philippines beginning in 1565

Florida /ˈflɒrᵻdə/ is a state located in the southeastern region of the United States. It is bordered to the west by the Gulf of Mexico, to the north by Alabama and Georgia, to the east by the Atlantic Ocean, Florida is the 22nd-most extensive, the 3rd-most populous, and the 8th-most densely populated of the U. S. states. Jacksonville is the most populous municipality in the state and is the largest city by area in the contiguous United States, the Miami metropolitan area is Floridas most populous urban area. The city of Tallahassee is the state capital, much of the state is at or near sea level and is characterized by sedimentary soil. The climate varies from subtropical in the north to tropical in the south, the American alligator, American crocodile, Florida panther, and manatee can be found in the Everglades National Park. It was a location of the Seminole Wars against the Native Americans. Today, Florida is distinctive for its large Cuban expatriate community and high population growth, the states economy relies mainly on tourism, agriculture, and transportation, which developed in the late 19th century. Florida is also renowned for amusement parks, orange crops, the Kennedy Space Center, Florida has attracted many writers such as Marjorie Kinnan Rawlings, Ernest Hemingway and Tennessee Williams, and continues to attract celebrities and athletes. It is internationally known for golf, tennis, auto racing, by the 16th century, the earliest time for which there is a historical record, major Native American groups included the Apalachee, the Timucua, the Ais, the Tocobaga, the Calusa and the Tequesta. Florida was the first part of the continental United States to be visited and settled by Europeans, the earliest known European explorers came with the Spanish conquistador Juan Ponce de León. Ponce de León spotted and landed on the peninsula on April 2,1513 and he named the region La Florida. The story that he was searching for the Fountain of Youth is a myth, in May 1539, Conquistador Hernando de Soto skirted the coast of Florida, searching for a deep harbor to land. He described seeing a wall of red mangroves spread mile after mile, some reaching as high as 70 feet. Very soon, many smokes appeared along the whole coast, billowing against the sky, the Spanish introduced Christianity, cattle, horses, sheep, the Spanish language, and more to Florida. Both the Spanish and French established settlements in Florida, with varying degrees of success, in 1559, Don Tristán de Luna y Arellano established a settlement at present-day Pensacola, making it the first attempted settlement in Florida, but it was abandoned by 1561. Spain maintained tenuous control over the region by converting the tribes to Christianity. The area of Spanish Florida diminished with the establishment of English settlements to the north, the English attacked St. Augustine, burning the city and its cathedral to the ground several times. Florida attracted numerous Africans and African-Americans from adjacent British colonies who sought freedom from slavery, in 1738, Governor Manuel de Montiano established Fort Gracia Real de Santa Teresa de Mose near St

Mughal painting
–
Mughal painting later spread to other Indian courts, both Muslim and Hindu, and later Sikh. This art of painting developed as a blending of Persian and Indian ideas, by the time of the Mughal invasion, the tradition had abandoned the high viewpoint typical of the Persian style, and adopted a more realistic style for animals and plants. No miniatures survive from the reign of the founder of the dynasty, Babur, nor does he mention commissioning any in his diaries, the Baburnama. Copies of this were illustrated by his descendents, Akbar in particular, with portraits of the many new animals Babur encountered when he invaded India. However some surviving un-illustrated manuscripts may have been commissioned by him, Mughal painting immediately took a much greater interest in realistic portraiture than was typical of Persian miniatures. Animals and plants were more realistically shown. Subjects are rich in variety and include portraits, events and scenes from life, wild life and hunting scenes. The Persian tradition of richly decorated borders framing the image was continued. The style of the Mughal school developed within the royal atelier, knowledge was primarily transmitted through familial and apprenticeship relationships, and the system of joint manuscript production which brought multiple artists together for single works. When Humayun returned to India, he brought him two accomplished Persian artists Abd al-Samad and Mir Sayyid Ali. His usurping brother Kamran Mirza had maintained a workshop in Kabul, humayans major known commission was a Khamsa of Nizami with 36 illuminated pages, in which the different styles of the various artists are mostly still apparent. Apart from the London painting, he commissioned at least two miniatures showing himself with family members, a type of subject that was rare in Persia but was to be common among the Mughals. Mughal painting developed and flourished during the reigns of Akbar, Jahangir, Akbar inherited and expanded his fathers library and atelier of court painters, and paid close personal attention to its output. He had studied painting in his youth under Abd as-Samad, though it is not clear how far these studies went. Between 1560 and 1566 the Tutinama, now in the Cleveland Museum of Art was illustrated, among other manuscripts, between 1562 and 1577 the atelier worked on an illustrated manuscript of the Hamzanama consisting of 1,400 canvas folios. Sadis masterpiece The Gulistan was produced at Fatehpur Sikri in 1582, a Darab Nama around 1585, Mughal style during this period continued to refine itself with elements of realism and naturalism coming to the fore. Between the years of 1570 to 1585 Akbar hired over a one hundred painters to practice Mughal style painting, Jahangir had an artistic inclination and during his reign Mughal painting developed further. Brushwork became finer and the colors lighter, Jahangir was also deeply influenced by European painting

Ustad Mansur
–
Ustad Mansur was a seventeenth-century Mughal painter and court artist. He grew in acclaim during the reign of Jahangir during which period he excelled at depicting plants and he was the earliest artist to depict the dodo in colour, apart from being the first to illustrate the Siberian crane. Towards the end of Akbars reign, he gained the title of ustad, although largely known for his natural history illustrations, he also portrayed people in various manuscript illustrations. The year of Mansurs birth is unknown and his name was suffixed in some early miniatures as Naqqash, which can refer to an artist, painter, or carver, indicating that he came from a family that was in an artistic profession. A single miniature showing Babur meeting his sister is attributed to Mansur and he was associated with other artists of the period including Basawan, Miskina and Nanha. During Akbars reign he appears to have involved only as a colourist in the plates for the Book of Akbar. Akbar followed the principle that all artwork should include the name of the artist on the margin, the British Museums copy of the Akbarnama includes some folios where his name is prefixed with ustad, indicating his rise to excellence. Early works included parts of portraits and other scenes, the earliest works were made as part of the Baburnama and most of these are as an assistant or a colourist. His Veena-player and coronation portrait of Jahangir are early works, in 1612, Jehangir received a turkey cock from Goa and this was illustrated by Mansur. In 1619, Jehangir received a Barbary falcon as a gift from Shah Abbas of Persia, Jehangir found it rare, in 1620, Jehangir visited Kashmir and spotted a brown dipper which he described in his memoirs translated as. In this stream I saw a bird like a saj and it dives and remains for a long time underneath and then comes up from a different place. I ordered them to catch and bring two or three of these birds, that I might ascertain whether they were waterfowl and were web-footed, one died immediately and the other lived for a day. Its feet were not webbed like a ducks, I ordered Nadirul-asr Ustad Mansur to draw its likeness. Mansur painted at least one hundred flowers from the Kashmir valley during this period, a red tulip from Kashmir is a better-known painting. The identity of the tulip is however debated with competing suggestions that include Tulipa lanata, T. montana, in 1621, Jehangir was gifted a zebra and this was perhaps the subject of the last miniature painting made by Mansur. It is suggested that his career ended with the reign of Jehangir in 1627, several other signed works, such as one of the Siberian crane and the other of a Bengal florican are in the Indian Museum, Kolkata. Some other works are in the National Museum, Delhi, the Maharaja Sawai Man Singh II Museum, Jaipur, not all of Mansurs birds were based on reality. He also created fantasy birds and many of the such as the flowers

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

Greek language
–
Greek is an independent branch of the Indo-European family of languages, native to Greece and other parts of the Eastern Mediterranean. It has the longest documented history of any living language, spanning 34 centuries of written records and its writing system has been the Greek alphabet for the major part of its history, other systems, such as Linear B and the Cypriot syllabary, were used previously. The alphabet arose from the Phoenician script and was in turn the basis of the Latin, Cyrillic, Armenian, Coptic, Gothic and many other writing systems. Together with the Latin texts and traditions of the Roman world, during antiquity, Greek was a widely spoken lingua franca in the Mediterranean world and many places beyond. It would eventually become the official parlance of the Byzantine Empire, the language is spoken by at least 13.2 million people today in Greece, Cyprus, Italy, Albania, Turkey, and the Greek diaspora. Greek roots are used to coin new words for other languages, Greek. Greek has been spoken in the Balkan peninsula since around the 3rd millennium BC, the earliest written evidence is a Linear B clay tablet found in Messenia that dates to between 1450 and 1350 BC, making Greek the worlds oldest recorded living language. Among the Indo-European languages, its date of earliest written attestation is matched only by the now extinct Anatolian languages, the Greek language is conventionally divided into the following periods, Proto-Greek, the unrecorded but assumed last ancestor of all known varieties of Greek. The unity of Proto-Greek would have ended as Hellenic migrants entered the Greek peninsula sometime in the Neolithic era or the Bronze Age, Mycenaean Greek, the language of the Mycenaean civilisation. It is recorded in the Linear B script on tablets dating from the 15th century BC onwards, Ancient Greek, in its various dialects, the language of the Archaic and Classical periods of the ancient Greek civilisation. It was widely known throughout the Roman Empire, after the Roman conquest of Greece, an unofficial bilingualism of Greek and Latin was established in the city of Rome and Koine Greek became a first or second language in the Roman Empire. The origin of Christianity can also be traced through Koine Greek, Medieval Greek, also known as Byzantine Greek, the continuation of Koine Greek in Byzantine Greece, up to the demise of the Byzantine Empire in the 15th century. Much of the written Greek that was used as the language of the Byzantine Empire was an eclectic middle-ground variety based on the tradition of written Koine. Modern Greek, Stemming from Medieval Greek, Modern Greek usages can be traced in the Byzantine period and it is the language used by the modern Greeks, and, apart from Standard Modern Greek, there are several dialects of it. In the modern era, the Greek language entered a state of diglossia, the historical unity and continuing identity between the various stages of the Greek language is often emphasised. Greek speakers today still tend to regard literary works of ancient Greek as part of their own rather than a foreign language and it is also often stated that the historical changes have been relatively slight compared with some other languages. According to one estimation, Homeric Greek is probably closer to demotic than 12-century Middle English is to modern spoken English, Greek is spoken by about 13 million people, mainly in Greece, Albania and Cyprus, but also worldwide by the large Greek diaspora. Greek is the language of Greece, where it is spoken by almost the entire population

Compound (linguistics)
–
In linguistics, a compound is a lexeme that consists of more than one stem. Compounding, composition or nominal composition is the process of formation that creates compound lexemes. That is, in terms, compounding occurs when two or more words are joined to make one longer word. The meaning of the compound may be similar to or different from the meanings of its components in isolation, with very few exceptions, English compound words are stressed on their first component stem. The process occurs readily in other Germanic languages for different reasons, words can be concatenated both to mean the same as the sum of two words or where an adjective and noun are compounded. The addition of affix morphemes to words should not be confused with nominal composition, compound formation rules vary widely across language types. In a synthetic language, the relationship between the elements of a compound may be marked with a case or other morpheme. This latter pattern is common throughout the Semitic languages, though in some it is combined with a genitive case. Agglutinative languages tend to very long words with derivational morphemes. Compounds may or may not require the use of derivational morphemes also, the longest compounds in the world may be found in the Finnic and Germanic languages. German examples include Farbfernsehgerät, Funkfernbedienung, and the jocular word Donaudampfschifffahrtsgesellschaftskapitänsmütze, in Finnish, although there is theoretically no limit to the length of compound words, words consisting of more than three components are rare. Even those with less than three components can look mysterious to non-Finnish such as hätäuloskäytävä, compounds can be rather long when translating technical documents from English to some other language, since the lengths of the words are theoretically unlimited, especially in chemical terminology. For example, the English compound doghouse, where house is the head, endocentric compounds tend to be of the same part of speech as their head, as in the case of doghouse. For example, the English compound white-collar is neither a kind of collar nor a white thing, in an exocentric compound, the word class is determined lexically, disregarding the class of the constituents. For example, a must-have is not a verb but a noun, the meaning of this type of compound can be glossed as whose B is A, where B is the second element of the compound and A the first. A bahuvrihi compound is one whose nature is expressed by neither of the words, copulative compounds are compounds with two semantic heads. Appositional compounds are lexemes that have two attributes that classify the compound, most natural languages have compound nouns. The positioning of the words according to the language

Monophyletic
–
In common cladistic usage, a monophyletic group is a taxon which forms a clade, meaning that it consists of an ancestral species and all its descendants. The term is synonymous with the uncommon term holophyly, monophyletic groups are typically characterized by shared derived characteristics. Monophyly is contrasted with paraphyly and polyphyly, as shown in the second diagram, a paraphyletic group consists of all of the descendants of a common ancestor minus one or more monophyletic groups. These definitions have taken time to be accepted. When the cladistic school of thought became mainstream in the 1960s, indeed, taxonomists sometimes used terms without defining them, leading to confusion in the early literature, a confusion which persists. On the broadest scale, definitions fall into two groups, willi Hennig defined monophyly as groups based on synapomorphy. Some authors have sought to define monophyly to include paraphyly as any two or more groups sharing a common ancestor, however, this broader definition encompasses both monophyletic and paraphyletic groups as defined above. Therefore, most scientists today restrict the term monophyletic to refer to groups consisting of all the descendants of one common ancestor, however, when considering taxonomic groups such as genera and species, the most appropriate nature of their common ancestor is unclear. Assuming that it would be one individual or mating pair is unrealistic for sexually reproducing species, some argue that using a broader definition, such as a species and all its descendants, does not really work to define a genus. According to D. M. Glossary of scientific naming Clade Paraphyly Polyphyly Crown group Abbey, graphical explanation of basic phylogenetic terms. Carr, Steven M. Concepts of monophyly, polyphyly & paraphyly

Animal coloration
–
Animal coloration is the general appearance of an animal resulting from the reflection or emission of light from its surfaces. Some animals are coloured, while others are hard to see. In some species, such as the peacock, the male has strong patterns, conspicuous colours and is iridescent, there are several separate reasons why animals have evolved colours. Camouflage enables an animal to remain hidden from view, some animals use flashes of colour to divert attacks by startling predators. Zebras may possibly use motion dazzle, confusing a predators attack by moving a bold pattern rapidly, some animals are coloured for physical protection, with pigments in the skin to protect against sunburn, while some frogs can lighten or darken their skin for temperature regulation. Finally, animals can be coloured incidentally, for example, blood is red because the haem pigment needed to carry oxygen is red. Animals coloured in these ways can have striking natural patterns, Animals produce colour in different ways. Pigments are particles of coloured material, chromatophores are cells containing pigment, which can change their size to make their colour more or less visible. Some animals, including butterflies and birds, have microscopic structures in scales, bristles or feathers which give them brilliant iridescent colours. Other animals including squid and some fish can produce light. Animals often use two or more of these together to produce the colours and effects they need. Animal coloration has been a topic of interest and research in biology for centuries, so each of those threads in the Microscope appears a large long body, consisting of a multitude of bright reflecting parts. According to Charles Darwins 1859 theory of selection, features such as coloration evolved by providing individual animals with a reproductive advantage. For example, individuals with slightly better camouflage than others of the species would, on average. Henry Walter Batess 1863 book The Naturalist on the River Amazons describes his extensive studies of the insects in the Amazon basin, the book introduced the concept of frequency-dependent selection, as when edible mimics are less frequent than the distasteful models whose colours and patterns they copy. In the book, Poulton also coined the term aposematism for warning coloration, which he identified in widely differing animal groups including mammals, bees and wasps, beetles, and butterflies. Frank Evers Beddards 1892 book, Animal Coloration, acknowledged that natural selection existed but examined its application to camouflage, mimicry, the book was in turn roundly criticised by Poulton. Hugh Bamford Cotts 500-page book Adaptive Coloration in Animals, published in wartime 1940, systematically described the principles of camouflage, the book contains hundreds of examples, over a hundred photographs and Cotts own accurate and artistic drawings, and 27 pages of references
