Naja Depereti
''Naja'' is a genus of venomous elapid snakes commonly known as cobras (or "true cobras"). Various species occur throughout Africa, Southwest Asia, South Asia, and Southeast Asia. Several other elapid species are often called "cobras", such as the king cobra and the rinkhals, but they are not "true cobras", in that they do not belong to the genus ''Naja''. Until recently, the genus ''Naja'' had 20 to 22 species, but it has undergone several taxonomic revisions in recent years, so sources vary greatly. Wide support exists, though, for a 2009 revision that synonymised the genera ''Boulengerina'' and '' Paranaja'' with ''Naja''. According to that revision, the genus ''Naja'' now includes 38 species. Etymology The origin of the generic name, ''Naja'', is from the Sanskrit ''nāga'' (with a hard "g") meaning "snake". Some hold that the Sanskrit word is cognate with English "snake", Germanic: ''*snēk-a-'', Proto-IE: ''*(s)nēg-o-'', but Manfred Mayrhofer calls this etymology " ...

Miocene
The Miocene ( ) is the first epoch (geology), geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene followed the Oligocene and preceded the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by distinct global events but by regionally defined transitions from the warmer Oligocene to the cooler Pliocene Epoch. During the Early Miocene, Afro-Arabia collided with Eurasia, severing the connection between the Mediterranean and Indian Oceans, and allowing the interchange of fauna between Eurasia and Africa, including the dispersal of proboscideans and Ape, hominoids into Eurasia. During the late Miocene, the conn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naja Oxiana
The Caspian cobra (''Naja oxiana''), also called the persian cobra or Russian cobra, is a species of highly venomous snake in the Family (biology), family Elapidae. The species is Endemism, endemic to Central Asia. First described by Karl Eichwald, a Germany, German physician, in 1831, it was for many years considered to be a subspecies of the Indian cobra, Naja naja until genetic analysis revealed it to be a distinct species. Taxonomy Karl Eichwald, a Baltic German, having been born modern day Saint Petersburg, Saint Petersburg, Russia, who was a physician and naturalist first described the Caspian cobra originally as ''Tomyris oxiana'' in 1831. Russian naturalist Alexander Strauch placed it in the genus ''Naja'' in 1868. The genus, generic name ''naja'' is a Latinisation of the Sanskrit word () meaning "cobra". The species, specific epithet ''oxiana'' is derived from the word in Latin language, Latin or () in Ancient Greek language, Greek, and refers to the ancient name of the ...

Egyptian Cobra
The Egyptian cobra (''Naja haje'') is one of the most venomous species of snakes in North Africa. It averages roughly in length; the longest specimen recorded so far measured . Etymology and taxonomy ''Naja haje'' was first described by Swedish zoologist Carl Linnaeus in 1758. The generic name ''naja'' is a Latinisation of the Sanskrit word () meaning " cobra". The specific epithet ''haje'' is derived from the Arabic word ''ḥayya'' () which literally means "snake". The snouted cobra (''Naja annulifera'') and Anchieta's cobra (''Naja anchietae'') were formerly regarded as subspecies of ''Naja haje'', but have since been shown to be distinct species. The Arabian populations were long recognised as a separate subspecies, ''Naja haje arabica'', and the black populations from Morocco sometimes as ''Naja haje legionis''. A recent study found that the Arabian cobra constitutes a separate species, ''Naja arabica'', whereas the subspecies ''legionis'' was synonymised with ''N. ...

Forest Cobra
The forest cobra (''Naja melanoleuca''), also commonly called the black cobra and the black and white-lipped cobra, is a species of highly venomous snake in the Family (biology), family Elapidae. The species is native to Africa, mostly the central and western parts of the continent. It is the largest Naja, true cobra species with a record length of . Although it prefers lowland forest and moist savanna habitats, this cobra is highly adaptable and can be found in drier climates within its geographical range. It is a very capable swimmer and is often considered to be semi-aquatic. The forest cobra is a generalist in its feeding habits, having a highly varied diet: anything from large insects to small mammals and other reptiles. This species is alert, nervous and is considered to be a medically significant snake. When cornered or molested, it will assume the typical cobra warning posture by raising its fore body off the ground, spreading a narrow hood, and hissing loudly. Bites to ...

Manfred Mayrhofer
Manfred Mayrhofer (26 September 1926 – 31 October 2011) was an Austrian Indo-Europeanist who specialized in Indo-Iranian languages. Mayrhofer served as professor emeritus at the University of Vienna. He is noted for his etymological dictionary of Sanskrit. Mayrhofer was born in Linz and studied Indo-European and Semitic linguistics and philosophy at the University of Graz, where he received his Ph.D. in 1949. From 1953 to 1963 he taught at the University of Würzburg, and from 1963 to 1966 he was a professor at Saarland University. In 1966 he returned to Austria, serving as professor at the University of Vienna until his retirement in 1990. He died in Vienna at the age of 85.

Proto-Indo-European Language
Proto-Indo-European (PIE) is the reconstructed common ancestor of the Indo-European language family. No direct record of Proto-Indo-European exists; its proposed features have been derived by linguistic reconstruction from documented Indo-European languages. Far more work has gone into reconstructing PIE than any other proto-language, and it is the best understood of all proto-languages of its age. The majority of linguistic work during the 19th century was devoted to the reconstruction of PIE and its daughter languages, and many of the modern techniques of linguistic reconstruction (such as the comparative method) were developed as a result. PIE is hypothesized to have been spoken as a single language from approximately 4500 BCE to 2500 BCE during the Late Neolithic to Early Bronze Age, though estimates vary by more than a thousand years. According to the prevailing Kurgan hypothesis, the original homeland of the Proto-Indo-Europeans may have been in the Pon ...

Cognate (etymology)
In historical linguistics, cognates or lexical cognates are sets of words that have been inherited in direct descent from an etymological ancestor in a common parent language. Because language change can have radical effects on both the sound and the meaning of a word, cognates may not be obvious, and it often takes rigorous study of historical sources and the application of the comparative method to establish whether lexemes are cognate. Cognates are distinguished from loanwords, where a word has been borrowed from another language. Name The English term ''cognate'' derives from Latin , meaning "blood relative". Examples An example of cognates from the same Indo-European root are: ''night'' ( English), ''Nacht'' ( German), ''nacht'' ( Dutch, Frisian), ''nag'' (Afrikaans), ''Naach'' ( Colognian), ''natt'' ( Swedish, Norwegian), ''nat'' ( Danish), ''nátt'' ( Faroese), ''nótt'' ( Icelandic), ''noc'' ( Czech, Slovak, Polish), ночь, ''noch'' ( Russian), ноќ, ''no ...

Sanskrit
Sanskrit (; stem form ; nominal singular , ,) is a classical language belonging to the Indo-Aryan languages, Indo-Aryan branch of the Indo-European languages. It arose in northwest South Asia after its predecessor languages had Trans-cultural diffusion, diffused there from the northwest in the late Bronze Age#South Asia, Bronze Age. Sanskrit is the sacred language of Hinduism, the language of classical Hindu philosophy, and of historical texts of Buddhism and Jainism. It was a lingua franca, link language in ancient and medieval South Asia, and upon transmission of Hindu and Buddhist culture to Southeast Asia, East Asia and Central Asia in the early medieval era, it became a language of religion and high culture, and of the political elites in some of these regions. As a result, Sanskrit had a lasting effect on the languages of South Asia, Southeast Asia and East Asia, especially in their formal and learned vocabularies. Sanskrit generally connotes several Indo-Aryan languages# ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...
