The capital and largest city is Prague; other major cities and urban areas include Brno, Ostrava, Plzeň and Liberec. The Duchy of Bohemia was founded in the late 9th century under Great Moravia. It was formally recognized as an Imperial Estate of the Holy Roman Empire in 1002 and became Kingdom of Bohemia, a kingdom in 1198. Following the Battle of Mohács in 1526, all of the Lands of the Bohemian Crown were gradually integrated into the Habsburg monarchy.

Konstantin Satunin
Konstantin Alekseevich Satunin (20 May 1863–10 November 1915) was a Russian zoologist who graduated at Moscow State University in 1890. From 1893 onward, he worked at a sericulture station in the Caucasus. He was a senior specialist at the Department of Agriculture between 1907 and 1915, concentrating on applied zoology and hunting in the Caucasus. He studied the mammals of Russia and Central Asia and published many works on the fauna of the Caucasus, mainly in the field of mammalogy but also entomology, herpetology, ichthyology, ornithology, sericulture, zoogeography, game management science and fishing.

Human Evolution
''Homo sapiens'' is a distinct species of the hominid family of primates, which also includes all the great apes. Over their evolutionary history, humans gradually developed traits such as Human skeletal changes due to bipedalism, bipedalism, dexterity, and complex language, as well as interbreeding with other hominins (a tribe of the Homininae, African hominid subfamily), indicating that human evolution was not linear but weblike. The study of the origins of humans involves Interdisciplinary, several scientific disciplines, including Biological anthropology, physical and evolutionary anthropology, paleontology, and genetics; the field is also known by the terms anthropogeny, anthropogenesis, and anthropogony—with the latter two sometimes used to refer to the related subject of hominization. Primate evolution, Primates diverged from other mammals about (Myr, mya), in the Late Cretaceous period, with their earliest fossils appearing over 55 mya, during the Paleocene. Prima ...

Cheetah
The cheetah (''Acinonyx jubatus'') is a large Felidae, cat and the Fastest animals, fastest land animal. It has a tawny to creamy white or pale buff fur that is marked with evenly spaced, solid black spots. The head is small and rounded, with a short snout and black tear-like facial streaks. It reaches at the shoulder, and the head-and-body length is between . Adults weigh between . The cheetah is capable of running at ; it has evolved specialized adaptations for speed, including a light build, long thin legs and a long tail. The cheetah was first Species description, described in the late 18th century. Four subspecies are recognised today that are native to Africa and central Iran. An African subspecies was Cheetah reintroduction in India, introduced to India in 2022. It is now distributed mainly in small, fragmented populations in northwestern, East Africa, eastern and southern Africa and central Iran. It lives in a variety of habitats such as savannahs in the Serengeti, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Big Cat
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. All cats descend from the ''Felidae'' family, sharing similar musculature, cardiovascular systems, skeletal frames, and behaviour. Both the cheetah and cougar differ physically from fellow big cats, and to a greater extent, other small cats. As obligate carnivores, big cats are considered apex predators, topping their food chain without natural predators of their own. Native ranges include the Americas, Africa, and Asia; the ranges of the leopard and tiger also extend into Europe, specifically in Russia.

Zdeněk Burian
Zdeněk Michael František Burian (11 February 1905 – 1 July 1981) was a Czech painter, book illustrator and palaeoartist. Burian's artwork played a central role in the development of palaeontological reconstruction and he is regarded as one of the most influential palaeoartists of all time. Burian began his career as an illustrator in the 1920s and became famous in his native Czechoslovakia for his illustrations of novels, mainly adventure novels and classic works. His illustrations of the novel ''The Mammoth Hunters'' (1937) by Eduard Štorch gained the attention of the Czech palaeontologist Josef Augusta, who collaborated with Burian as a scientific advisor. Their collaboration resulted in Burian's work being used in a number of books on prehistoric life written by Augusta, culminating in a series of six great illustrated volumes published in 1956–1966, the most famous of which was ''Prehistoric Animals'' (1956). After Augusta's death in 1968, Burian worked with numerou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Homo (genus)
''Homo'' () is a genus of great ape (family Hominidae) that emerged from the genus ''Australopithecus'' and encompasses only a single extant species, ''Homo sapiens'' (modern humans), along with a number of extinct species (collectively called archaic humans) classified as either ancestral or closely related to modern humans; these include '' Homo erectus'' and '' Homo neanderthalensis''. The oldest member of the genus is '' Homo habilis'', with records of just over 2 million years ago. ''Homo'', together with the genus ''Paranthropus'', is probably most closely related to the species ''Australopithecus africanus'' within ''Australopithecus''.'''' The closest living relatives of ''Homo'' are of the genus '' Pan'' ( chimpanzees and bonobos), with the ancestors of ''Pan'' and ''Homo'' estimated to have diverged around 5.7–11 million years ago during the Late Miocene. ''H. erectus'' appeared about 2 million years ago and spread throughout Africa (debatably ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cetacean
Cetacea (; , ) is an infraorder of aquatic mammals belonging to the order Artiodactyla that includes whales, dolphins and porpoises. Key characteristics are their fully aquatic lifestyle, streamlined body shape, often large size and exclusively carnivorous diet. They propel themselves through the water with powerful up-and-down movements of their tail, which ends in a paddle-like fluke, using their flipper-shaped forelimbs to steer. While the majority of cetaceans live in marine environments, a small number reside solely in brackish water, brackish or fresh water. Having a cosmopolitan distribution, they can be found in some rivers and all of Earth's oceans, and many species migrate throughout vast ranges with the changing of the seasons. Cetaceans are famous for cetacean intelligence, their high intelligence, complex social behaviour, and the enormous size of some of the group's members. For example, the blue whale reaches a maximum confirmed length of and a weight of 173 tonne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indochinese Tiger
The Indochinese tiger is a population of the '' Panthera tigris tigris'' subspecies that is native to Southeast Asia. This population occurs in Myanmar and Thailand. In 2011, the population was thought to comprise 342 individuals, including 85 in Myanmar and 20 in Vietnam, with the largest population unit surviving in Thailand, estimated at 189 to 252 individuals during the period 2009 to 2014. Taxonomy ''Panthera tigris corbetti'' was proposed as a scientific name for this specific population by Vratislav Mazák in 1968 based on skin colouration, marking pattern, and skull dimensions. It was named in honor of Jim Corbett. In 2017, the Cat Classification Task Force of the Cat Specialist Group revised felid taxonomy and now recognizes the tiger populations of mainland South and Southeast Asia as belonging to the nominate subspecies ''P. tigris tigris''. Results of a genetic study published in 2018 supported six monophyletic clades based on whole genome sequencing analysis of 32 t ...
