Big Cats
The term "big cat" is typically used to refer to any of the five living members of the genus '' Panthera'', namely the tiger, lion, jaguar, leopard, and snow leopard. Despite enormous differences in size, various cat species are quite similar in both structure and behaviour, with the exception of the cheetah, which significantly stands out from the other big and small cats. All cats are carnivores and some are efficient apex predators. Their native ranges include the Americas, Africa, and Asia; the leopard's range also extends into Europe, specifically in Russia.

Panthera
''Panthera'' is a genus within the family (biology), family Felidae that was named and described by Lorenz Oken in 1816 who placed all the spotted cats in this group. Reginald Innes Pocock revised the classification of this genus in 1916 as comprising the tiger (''P. tigris''), lion (''P. leo''), jaguar (''P. onca''), and leopard (''P. pardus'') on the basis of common Cranial bones, cranial features. Results of genetic analysis indicate that the snow leopard (formerly ''Uncia uncia'') also belongs to the genus ''Panthera'' (''P. uncia''), a classification that was accepted by IUCN Red List assessors in 2008. The tiger, lion, jaguar and leopard are the only cat species with anatomical structures that enable them to Roar (utterance), roar; the snow leopard cannot. The primary reason for this was formerly assumed to be the incomplete ossification of the hyoid bone. However, new studies show the ability to roar is due to other Morphology (biology), morphological features, especiall ...

Europe
Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a Continent#Subcontinents, subcontinent of Eurasia and it is located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. Comprising the westernmost peninsulas of Eurasia, it shares the continental landmass of Afro-Eurasia with both Africa and Asia. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south and Asia to the east. Europe is commonly considered to be Boundaries between the continents of Earth#Asia and Europe, separated from Asia by the drainage divide, watershed of the Ural Mountains, the Ural (river), Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea and the waterways of the Turkish Straits. "Europe" (pp. 68–69); "Asia" (pp. 90–91): "A commonly accepted division between Asia and E ...

Evolution
Evolution is change in the heritable characteristics of biological populations over successive generations. These characteristics are the expressions of genes, which are passed on from parent to offspring during reproduction. Variation tends to exist within any given population as a result of genetic mutation and recombination. Evolution occurs when evolutionary processes such as natural selection (including sexual selection) and genetic drift act on this variation, resulting in certain characteristics becoming more common or more rare within a population. The evolutionary pressures that determine whether a characteristic is common or rare within a population constantly change, resulting in a change in heritable characteristics arising over successive generations. It is this process of evolution that has given rise to biodiversity at every level of biological organisation, including the levels of species, individual organisms, and molecules. The theory of evolution by ...

Cougar
The cougar (''Puma concolor'') is a large Felidae, cat native to the Americas. Its Species distribution, range spans from the Canadian Yukon to the southern Andes in South America and is the most widespread of any large wild terrestrial mammal in the Western Hemisphere. It is an adaptable, Generalist and specialist species, generalist species, occurring in most American habitat types. This wide range has brought it many common names, including puma, mountain lion, catamount and panther (for the Florida sub-population). It is the second-largest cat in the New World, after the jaguar (''Panthera onca''). Secretive and largely solitary by nature, the cougar is properly considered both nocturnal and crepuscular, although daytime sightings do occur. Despite its size, the cougar is more closely related to smaller felines, including the domestic cat (''Felis catus'') than to any species of the subfamily Pantherinae. The cougar is an ambush predator that pursues a wide variety of pre ...

Domestic Cat
The cat (''Felis catus'') is a domestic species of small carnivorous mammal. It is the only domesticated species in the family Felidae and is commonly referred to as the domestic cat or house cat to distinguish it from the wild members of the family. Cats are commonly kept as house pets but can also be farm cats or feral cats; the feral cat ranges freely and avoids human contact. Domestic cats are valued by humans for companionship and their ability to kill rodents. About 60 cat breeds are recognized by various cat registries. The cat is similar in anatomy to the other felid species: they have a strong flexible body, quick reflexes, sharp teeth, and retractable claws adapted to killing small prey. Their night vision and sense of smell are well developed. Cat communication includes vocalizations like meowing, purring, trilling, hissing, growling, and grunting as well as cat-specific body language. Although the cat is a social species, they are a solitary hunter. As ...

Smithsonian Institution
The Smithsonian Institution ( ), or simply the Smithsonian, is a group of museums and education and research centers, the largest such complex in the world, created by the U.S. government "for the increase and diffusion of knowledge". Founded on August 10, 1846, it operates as a trust instrumentality and is not formally a part of any of the three branches of the federal government. The institution is named after its founding donor, British scientist James Smithson. It was originally organized as the United States National Museum, but that name ceased to exist administratively in 1967. Called "the nation's attic" for its eclectic holdings of 154 million items, the institution's 19 museums, 21 libraries, nine research centers, and zoo include historical and architectural landmarks, mostly located in the District of Columbia. Additional facilities are located in Maryland, New York, and Virginia. More than 200 institutions and museums in 45 states,States without Smithsonian ...

Puma (genus)
''Puma'' is a genus in the family Felidae whose only extant species is the cougar (also known as the puma, mountain lion, and panther, among other names), and may also include several poorly known Old World fossil representatives (for example, '' Puma pardoides'', or Owen's panther, a large, cougar-like cat of Eurasia's Pliocene). In addition to these potential Old World fossils, a few New World fossil representatives are possible, such as '' Puma pumoides'' and the two species of the so-called "American cheetah", currently classified under the genus ''Miracinonyx''. Description Pumas are large, secretive cats. They are also commonly known as cougars and mountain lions, and are able to reach larger sizes than some other "big" cat individuals. Despite their large size, they are more closely related to smaller feline species than to lions or leopards. The seven subspecies of pumas all have similar characteristics but tend to vary in color and size. Pumas are the most adaptable fe ...

Cheetah
The cheetah (''Acinonyx jubatus'') is a large cat native to Africa and central Iran. It is the fastest land animal, estimated to be capable of running at with the fastest reliably recorded speeds being , and as such has evolved specialized adaptations for speed, including a light build, long thin legs and a long tail. It typically reaches at the shoulder, and the head-and-body length is between . Adults weigh between . Its head is small and rounded, with a short snout and black tear-like facial streaks. The coat is typically tawny to creamy white or pale buff and is mostly covered with evenly spaced, solid black spots. Four subspecies are recognised. The cheetah lives in three main social groups: females and their cubs, male "coalitions", and solitary males. While females lead a nomadic life searching for prey in large home ranges, males are more sedentary and instead establish much smaller territories in areas with plentiful prey and access to females. The cheetah is act ...

Acinonyx
''Acinonyx'' is a genus within the cat family. The only living species of the genus, the cheetah (''A. jubatus''), lives in open grasslands of Africa and Asia. Several fossil remains of cheetah-like cats were excavated that date to the late Pliocene and Middle Pleistocene. These cats occurred in Africa, parts of Europe and Asia about 10,000 years ago. Several similar species, classified in the genus ''Miracinonyx'', lived in North America at the same time; these may have been more closely related to the genus '' Puma''. Taxonomy ''Acinonyx'' was proposed by Joshua Brookes in 1828. Between the late 18th century and the early 20th century, the following ''Acinonyx'' species and subspecies were described: * ''Felis jubatus'' by Johann Christian Daniel von Schreber in 1777 was based on earlier descriptions by Comte de Buffon and Thomas Pennant. ** ''Felis venatica'' by Griffith in 1821 was based on a sketch of a cheetah from India. ** ''Cynailurus soemmeringi'' by Fitzinger ...

Felinae
The Felinae are a subfamily of the family Felidae. This subfamily comprises the small cats having a bony hyoid, because of which they are able to 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; thus excluding all fossil cat species. Characteristics The members of the Felinae have retractile claws that are protected by at least one cutaneous lobe. Their larynx is kept close to the base of the skull by an 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 ''Felis''. In 1917, Reginald Innes Pocock also subordinated the following genera to the Felinae that had been propo ...
