Rusty-spotted Cat
The rusty-spotted cat (''Prionailurus rubiginosus'') is one of the cat family's smallest members, of which historical records are known only from India and Sri Lanka. In 2012, it was also recorded in the western Terai of Nepal. Since 2016, the global wild population is listed as Near Threatened on the IUCN Red List as it is fragmented and affected by loss and destruction of its prime habitat, deciduous forests. Taxonomy ''Felis rubiginosa'' was the scientific name used by Isidore Geoffroy Saint-Hilaire in 1831 for a rusty-spotted cat specimen from Pondicherry, India. ''Prionailurus'' was proposed by Nikolai Severtzov in 1858 as a generic name. ''Prionailurus rubiginosus phillipsi'' was proposed by Reginald Innes Pocock in 1939 who described a specimen from Central Province, Sri Lanka and subordinated both to the genus ''Prionailurus''. Phylogeny Phylogenetic analysis of the nuclear DNA in tissue samples from all Felidae species revealed that the evolutionary radiation of the ...

Isidore Geoffroy Saint-Hilaire
Isidore Geoffroy Saint-Hilaire (; 16 December 1805 – 10 November 1861) was a French zoologist and an authority on deviation from normal structure. In 1854 he coined the term ''éthologie'' (ethology). Biography He was born in Paris, the son of Étienne Geoffroy Saint-Hilaire. In his earlier years he showed an aptitude for mathematics, but eventually he devoted himself to the study of natural history and of medicine, and in 1824 he was appointed assistant naturalist to his father. In 1829 he delivered for his father the second part of a course of lectures on ornithology, and during the following three years he taught zoology at the ''Athénée'', and teratology at the ''École pratique''. He was elected a member of the French Academy of Sciences in 1833, was in 1837 appointed to act as deputy for his father at the faculty of sciences in Paris. During the following year he was sent to Bordeaux to organize a similar faculty there. He became successively; inspector of the ac ...

Evolutionary Radiation
An evolutionary radiation is an increase in taxonomic diversity that is caused by elevated rates of speciation, that may or may not be associated with an increase in morphological disparity. A significantly large and diverse radiation within a relatively short geologic time scale (e.g. a period or epoch) is often referred to as an explosion. Radiations may affect one clade or many, and be rapid or gradual; where they are rapid, and driven by a single lineage's adaptation to their environment, they are termed adaptive radiations. Examples Perhaps the most familiar example of an evolutionary radiation is that of placental mammals immediately after the extinction of the non-avian dinosaurs at the end of the Cretaceous, about 66 million years ago. At that time, the placental mammals were mostly small, insect-eating animals similar in size and shape to modern shrews. By the Eocene (58–37 million years ago), they had evolved into such diverse forms as bats, whales, and hor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Pantherinae
The Pantherinae is a subfamily of the Felidae; it was named and first described by Reginald Innes Pocock in 1917 as only including the ''Panthera'' species, but later also came to include the clouded leopards (genus ''Neofelis''). The Pantherinae genetically diverged from a common ancestor between and . Characteristics Pantherinae species are characterised by an imperfectly ossified hyoid bone with elastic tendons that enable their larynx to be mobile. They have a flat rhinarium that only barely reaches the dorsal side of the nose. The area between the nostrils is narrow, and not extended sidewards as in the Felinae. The ''Panthera'' species have a single, rounded, vocal fold with a thick mucosal lining, a large vocalis muscle, and a large cricothyroid muscle with long and narrow membranes. A vocal fold that is longer than enables all but the snow leopard among them to roar, as it has shorter vocal folds of that provide a lower resistance to airflow; this distinction w ...

Pallas's Cat
The Pallas's cat (''Otocolobus manul''), also known as the manul, is a small wild cat with long and dense light grey fur, and rounded ears set low on the sides of the head. Its head-and-body length ranges from with a long bushy tail. It is well camouflaged and adapted to the cold continental climate in its native range, which receives little rainfall and experiences a wide range of temperatures. The Pallas's cat was first described in 1776 by Peter Simon Pallas, who observed it in the vicinity of Lake Baikal. Since then, it has been recorded across a large region in Central Asia, albeit in widely spaced sites from the Caucasus, Iranian Plateau, Hindu Kush, parts of the Himalayas, Tibetan Plateau to the Altai-Sayan region and South Siberian Mountains. It inhabits rocky montane grasslands and shrublands, where the snow cover is below . It finds shelter in rock crevices and burrows, and preys foremost on lagomorphs and rodents. The female gives birth to between two and six ki ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Felinae
The small cats or Felinae are a subfamily of Felidae distinguished by their bony hyoids, which let them purr but not roar. Other authors have proposed an alternative definition for this subfamily, as comprising only the living conical-toothed cat genera with two tribes, the Felini and Pantherini, and excluding the extinct sabre-toothed Machairodontinae. Characteristics The members of the Felinae have retractile claws that are protected by at least one cutaneous Lobe (anatomy), lobe. Their larynx is kept close to the base of the skull by an Ossification, ossified hyoid. They can purr owing to the vocal folds being shorter than . The cheetah ''Acinonyx'' does not have cutaneous sheaths for guarding claws. Taxonomy The term 'Felini' was first used in 1817 by Gotthelf Fischer von Waldheim, at the time for all the cat species that had been proposed as belonging to the Genus (biology), genus ''Felis''. In 1917, Reginald Innes Pocock also subordinated the following genera to the Felinae ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Felidae
Felidae ( ) is the Family (biology), family of mammals in the Order (biology), order Carnivora colloquially referred to as cats. A member of this family is also called a felid ( ). The 41 extant taxon, extant Felidae species exhibit the greatest diversity in fur patterns of all terrestrial carnivores. Cats have retractile claws, slender muscular bodies and strong flexible forelimbs. Their teeth and facial muscles allow for a powerful bite. They are all obligate carnivores, and most are solitary predators ambushing or stalking their prey. Wild cats occur in Africa, Europe, Asia and the Americas. Some wild cat species are adapted to forest and savanna habitats, some to arid environments, and a few also to wetlands and mountainous terrain. Their activity patterns range from nocturnal and crepuscular to Diurnality, diurnal, depending on their preferred prey species. Reginald Innes Pocock divided the extant Felidae into three subfamilies: the Pantherinae, the Felinae and the Acin ...

Cladogram
A cladogram (from Greek language, Greek ''clados'' "branch" and ''gramma'' "character") is a diagram used in cladistics to show relations among organisms. A cladogram is not, however, an Phylogenetic tree, evolutionary tree because it does not show how ancestors are related to descendants, nor does it show how much they have changed, so many differing evolutionary trees can be consistent with the same cladogram. A cladogram uses lines that branch off in different directions ending at a clade, a group of organisms with a last common ancestor. There are many shapes of cladograms but they all have lines that branch off from other lines. The lines can be traced back to where they branch off. These branching off points represent a hypothetical ancestor (not an actual entity) which can be inferred to exhibit the traits shared among the terminal taxa above it. This hypothetical ancestor might then provide clues about the order of evolution of various features, adaptation, and other e ...

Fishing Cat
The fishing cat (''Prionailurus viverrinus'') is a medium-sized wild cat of South and Southeast Asia. It has a deep yellowish-grey fur with black lines and spots. Adults have a head-to-body length of , with a long tail. Males are larger than females, weighing , while females average . It lives mostly in the vicinity of wetlands, along rivers, streams, oxbow lakes, in swamps and mangroves where it preys mostly on fish. Other prey items include birds, insects, small rodents, molluscs, reptiles including snakes, amphibians and carrion of cattle. The fishing cat is thought to be primarily nocturnal. It is a good swimmer and can swim long distances, even underwater. The fishing cat has been listed as a vulnerable species on the IUCN Red List since 2016, as the global population is thought to have declined by about 30% in the past three fishing cat generations during the period 2010–2015. The destruction of wetlands and killing by local people are the major threats throughout its ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Flat-headed Cat
The flat-headed cat (''Prionailurus planiceps'') is a felinae, small wild cat with short reddish-brown fur. Its head is elongated, and its ears are rounded. Its slender body is long with a tail of , and it weighs . The flat-headed cat was first described in 1827 based on a zoological specimen collected in Sumatra. It is also native to the Thai-Malay Peninsula and Borneo, and inhabits wetlands like mixed freshwater swamp forests and lowland freshwater swamps near rivers and coastal areas. It preys foremost on fish, frogs and crustaceans. The flat-headed cat is threatened by habitat destruction due to conversion for settlements, agriculture and oil palm plantations. It has been listed on the IUCN Red List as Endangered species, Endangered since 2008. Taxonomy The scientific name ''Felis planiceps'' was proposed by Nicholas Aylward Vigors and Thomas Horsfield in 1827, who first described a skin of a flat-headed cat specimen collected in Sumatra. ''Prionailurus'' was proposed by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Lineage (genetic)
A genetic lineage includes all descendants of a given genetic sequence, typically following a new mutation. It is not the same as an allele because it excludes cases where different mutations give rise to the same allele, and includes descendants that differ from the ancestor by one or more mutations. The genetic sequence can be of different sizes, e.g. a single gene or a haplotype containing multiple adjacent genes along a chromosome. Given recombination, each gene can have a separate genetic lineages, even as the population shares a single organismal lineage. In asexual microbes or somatic cells, cell lineages exactly match genetic lineages, and can be traced. Incomplete lineage sorting Incomplete lineage sorting describes when the phylogenetic tree for a gene does not match that of the species. For example, while most human gene lineages coalesce first with chimpanzee lineages, and then with gorilla lineages, other configurations also occur. Lineage selection Lineage s ...

Genetic Divergence
Genetic divergence is the process in which two or more populations of an ancestral species accumulate independent genetic changes ( mutations) through time, often leading to reproductive isolation and continued mutation even after the populations have become reproductively isolated for some period of time, as there is not any genetic exchange anymore. In some cases, subpopulations cover living in ecologically distinct peripheral environments can exhibit genetic divergence from the remainder of a population, especially where the range of a population is very large (see parapatric speciation). The genetic differences among divergent populations can involve silent mutations (that have no effect on the phenotype) or give rise to significant morphological and/or physiological changes. Genetic divergence will always accompany reproductive isolation, either due to novel adaptations via selection and/or due to genetic drift, and is the principal mechanism underlying speciation.

Common Ancestor
Common descent is a concept in evolutionary biology applicable when one species is the ancestor of two or more species later in time. According to modern evolutionary biology, all living beings could be descendants of a unique ancestor commonly referred to as the last universal common ancestor (LUCA) of all life on Earth. Common descent is an effect of speciation, in which multiple species derive from a single ancestral population. The more recent the ancestral population two species have in common, the more closely they are related. The most recent common ancestor of all currently living organisms is the last universal ancestor, which lived about 3.9 billion years ago. The two earliest pieces of evidence for life on Earth are graphite found to be biogenic in 3.7 billion-year-old metasedimentary rocks discovered in western Greenland and microbial mat fossils found in 3.48 billion-year-old sandstone discovered in Western Australia. All currently living organisms on Earth sha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
