Information: - The Indo-European languages are a language family of several hundred related languages and dialects. There are about 445 living Indo-European languages, according to the estimate by "Ethnologue", with over two-thirds (313) of them belonging to the Indo-Iranian branch. The most widely spoken Indo-European languages by native speakers are Spanish, English, Hindustani (Hindi and Urdu), Portuguese, Bengali, Russian, Persian and Punjabi, each with over 100 million speakers. Today, 46% of the human population speaks an Indo-European language natively, by far the highest of any language family. - A camel is an even-toed ungulate within the genus Camelus, bearing distinctive fatty deposits known as "humps" on its back. The three surviving species of camel are the dromedary, or one-humped camel ("C. dromedarius"), which inhabits the Middle East and the Horn of Africa; the Bactrian, or two-humped camel ("C. bactrianus"), which inhabits Central Asia; and the critically endangered wild Bactrian camel ("C. ferus") that has limited populations in remote areas of northwest China and Mongolia. Bactrian camels take their name from the historical Bactria region of Central Asia (Yam & Khomeiri, 2015). Both the dromedary and the Bactrian camels have been domesticated; they provide milk, meat, hair for textiles or goods such as felted pouches, and are working animals with tasks ranging from human transport to bearing loads. - The Bactrian camel ("Camelus bactrianus") is a large, even-toed ungulate native to the steppes of Central Asia. The Bactrian camel has two humps on its back, in contrast to the single-humped dromedary camel. Its population of two million exists mainly in the domesticated form. Some authorities, notably the International Union for Conservation of Nature (IUCN), use the binomial name "Camelus ferus" for the wild Bactrian camel and reserve "Camelus bactrianus" for the domesticated Bactrian camel. Their name comes from the ancient historical region of Bactria. - Mongolia (Mongolian: ["Monggol Ulus"] in Mongolian script; ["Mongol Uls"] in Mongolian Cyrillic) is a landlocked unitary sovereign state in East Asia. Its area is roughly equivalent with the historical territory of Outer Mongolia, and that term is sometimes used to refer to the current state. It is sandwiched between China to the south and Russia to the north. While it does not share a border with Kazakhstan, Mongolia is separated from it by only . - The llama (Lama glama) is a domesticated South American camelid, widely used as a meat and pack animal by Andean cultures since the Pre-Columbian era. - Invertebrates are animals that neither possess nor develop a vertebral column (commonly known as a "backbone" or "spine"), derived from the notochord. This includes all animals apart from the subphylum Vertebrata. Familiar examples of invertebrates include insects; crabs, lobsters and their kin; snails, clams, octopuses and their kin; starfish, sea-urchins and their kin; and worms. - Tylopoda (meaning "swollen foot") is a suborder of terrestrial herbivorous even-toed ungulates belonging to the order Artiodactyla. They are found in the wild in their native ranges of South America and Asia, while Australian feral camels are introduced. The group has a long fossil history in North America and Europe. Tylopoda appeared during the Eocene around 46.2 million years ago. - The Horn of Africa (, "yaafrika qand", "al-qarn al-'afrq") (shortened to HOA) is a peninsula in Northeast Africa. It juts hundreds of kilometers into the Arabian Sea and lies along the southern side of the Gulf of Aden. The area is the easternmost projection of the African continent. The Horn of Africa denotes the region containing the countries of Djibouti, Eritrea, Ethiopia, and Somalia. - A working animal is an animal, usually domesticated, that is kept by humans and trained to perform tasks. They may be close members of the family, such as guide dogs or other assistance dogs, or they may be animals trained to provide tractive force, such as draft horses or logging elephants. The latter types of animals are called draft animals (draught animals) or beasts of burden. Most working animals are either service animals or draft animals. They may also be used for milking or herding, jobs that require human training to encourage the animal to cooperate. Some, at the end of their working lives, may also be used for meat or other products such as leather. - An alpaca ("Vicugna pacos") is a domesticated species of South American camelid. It resembles a small llama in appearance. - Camelids are members of the biological family Camelidae, the only currently living family in the suborder Tylopoda. The extant members of this group are: dromedary camels, Bactrian camels, wild Bactrian camels, llamas, alpacas, vicunas, and guanacos. - The Miocene is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Sir Charles Lyell. Its name comes from the Greek words (', less) and (', new) and means "less recent" because it has 18% fewer modern sea invertebrates than the Pliocene. The Miocene follows the Oligocene Epoch and is followed by the Pliocene Epoch. - 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. - Aepycamelus is an extinct genus of camelid , formerly called Alticamelus , which lived during the Miocene 20.6 -- 4.9 million years ago , existing for about 15.7 million years . Its name is derived from the Homeric Greek , '' high and steep '' and -- '' camel '' ; thus , '' high camel '' ; alticamelus in Latin . Aepycamelus walked on its toes only . Unlike earlier species of camelids , they possessed cushioned pads like those of modern camels . - The vicuna ("Vicugna vicugna") or vicugna (both ) is one of two wild South American camelids which live in the high alpine areas of the Andes, the other being the guanaco. It is a relative of the llama, and is now believed to be the wild ancestor of domesticated alpacas, which are raised for their coats. Vicunas produce small amounts of extremely fine wool, which is very expensive because the animal can only be shorn every three years, and has to be caught from the wild. When knitted together, the product of the vicuna's wool is very soft and warm. The Inca valued vicunas highly for their wool, and it was against the law for anyone but royalty to wear vicuna garments; today the vicuna is the national animal of Peru and appears in the Peruvian coat of arms. - The even-toed ungulates (order Artiodactyla) are ungulates (hoofed animals) whose weight is borne equally by the third and fourth toes. By contrast, odd-toed ungulates, such as horses, bear their weight primarily on their third toe. The aquatic Cetaceans (whales, dolphins, and porpoises) evolved from even-toed ungulate ancestors, and therefore modern taxonomic classification combines Artiodactyla and Cetacea into Cetartiodactyla. - The Neogene is a geologic period and system that spans 20.45 million years from the end of the Paleogene Period million years ago (Mya) to the beginning of the present Quaternary Period Mya. The Neogene is sub-divided into two epochs, the earlier Miocene and the later Pliocene. Some geologists assert that the Neogene cannot be clearly delineated from the modern geological period, the Quaternary. - The dromedary (or ), also called the Arabian camel ("Camelus dromedarius"), is a large, even-toed ungulate with one hump on its back. The dromedary is the smallest of the three species of camel; adult males stand at the shoulder, while females are tall. Males typically weigh between , and females weigh between . The species' distinctive features include its long, curved neck, narrow chest, a single hump (compared with two on the Bactrian camel and wild Bactrian camel), and long hairs on the throat, shoulders and hump. The coat is generally a shade of brown. The hump, tall or more, is made of fat bound together by fibrous tissue. - The guanaco ("Lama guanicoe"), a camelid native to South America, stands between at the shoulder and weighs . Its color varies very little (unlike the domestic llama), ranging from a light brown to dark cinnamon and shading to white underneath. Guanacos have grey faces and small, straight ears. - The Pliocene (also Pleiocene) Epoch is the epoch in the geologic timescale that extends from 5.333 million to 2.58 million years BP. It is the second and youngest epoch of the Neogene Period in the Cenozoic Era. The Pliocene follows the Miocene Epoch and is followed by the Pleistocene Epoch. Prior to the 2009 revision of the geologic time scale, which placed the four most recent major glaciations entirely within the Pleistocene, the Pliocene also included the Gelasian stage, which lasted from 2.588 to 1.806 million years ago, and is now included in the Pleistocene. - Sir Charles Lyell, 1st Baronet, (14 November 1797 22 February 1875) was a British lawyer and the foremost geologist of his day. He is best known as the author of "Principles of Geology", which popularized James Hutton's concepts of uniformitarianismthe idea that the Earth was shaped by the same processes still in operation today. "Principles of Geology" also challenged theories popularized by Georges Cuvier, which were the most accepted and circulated ideas about geology in England at the time.
