Bos Primigenius Namadicus
The Indian aurochs (''Bos primigenius namadicus''; ) is an extinct subspecies of aurochs that inhabited West Asia and the Indian subcontinent from the Late Pleistocene until its eventual extinction during the South Asian Stone Age. With no remains younger than 3,800 YBP ever recovered, the Indian aurochs was the first of the three aurochs subspecies to become extinct; the Eurasian aurochs (''B. p. primigenius'') and the North African aurochs (''B. p. mauritanicus'') persevered longer, with the latter being known to the Roman Empire, and the former surviving until the mid-17th century in Central Europe.Chen et al., 2010: "Zebu cattle are an exclusive legacy of the South Asia Neolithic." ''Molecular biology and evolution'', 27(1), 1-6(in Supplementary Data) Two breeds/subspecies of domestic cattle (''Bos taurus''), the sanga (''B. t. africanus'') and the zebu (''B. indicus''), can trace their genetic heritage directly to the Indian aurochs.

The IUCN Red List Of Threatened Species
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is an inventory of the global conservation status and extinction risk of biological species. A series of Regional Red Lists, which assess the risk of extinction to species within a political management unit, are also produced by countries and organizations. The goals of the Red List are to provide scientifically based information on the status of species and subspecies at a global level, to draw attention to the magnitude and importance of threatened biodiversity, to influence national and international policy and decision-making, and to provide information to guide actions to conserve biological diversity. Major species assessors include BirdLife International, the Institute of Zoology (the research division of the Zoological Society of London), the World Conservation Monitoring Centre, and many Specialist Groups within th ...

Sanga Cattle
Sanga cattle is the collective name for indigenous cattle of some regions in Africa. They are sometimes identified as a subspecies with the scientific name ''Bos taurus africanus''. Their history of domestication and their origins in relation to taurine cattle, zebu cattle (indicine), and native African varieties of the ancestral aurochs are a matter of debate. "African taurine", "sanga", "zenga", "sheko", "African indicine" are all sub-groups of Sanga cattle. Genetic signatures and classification A relatively complete survey on the many breeds of Sanga cattle is Kim ''et al.'' 2020. Admixture analysis from this paper groups Sanga cattle under the following taxonomy: * African taurine (N'Dama, Muturu) * African humped cattle ** African indicine (Mursi) ** African zenga (Fogera, Horro) ** African sanga (Ankole) ** Sheko In the analyses cited by Kim, African taurine (''Bos taurus taurus'') first split from Eurasian taurine. A group of Asian indicine cattle ("Zebu", ''Bos taur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kathiawar Peninsula
Kathiawar (), also known as Saurashtra, is a peninsula in the south-western Gujarat state in India, bordering the Arabian Sea and covering about . It is bounded by the Kutch district in the north, the Gulf of Kutch in the northwest, and by the Gulf of Khambhat in the east. In the northeast, it is connected to the rest of the state and borders on the low, fertile hinterland of Ahmedabad. It is crossed by two belts of hill country and is drained radially by nine rivers which have little natural flow aside from in monsoon months, thus dams have been built on some of these. Kathiawar ports have been flourishing centres of trade and commerce since at least the 16th century. It was formerly a state of India. Etymology and history The name Kathiawad seems to have been derived from the early settlements of Kathikas or Kathis who entered Gujarat from Sindh in early centuries of the Common Era. The name "Saurashtra" itself is from Sanskrit (, ), the vṛddhi form of (, ), derived ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Early Holocene
In the geologic time scale, the Greenlandian is the earliest age or lowest stage of the Holocene Epoch or Series, part of the Quaternary. Beginning in 11,650 BP (9701 BCE or 300 HE) and ending with the 8.2-kiloyear event (c. 8200–8300 BP, 6200–6300 BCE, 3600–3700 HE), it is the earliest of three sub-divisions of the Holocene. It was officially ratified by the International Commission on Stratigraphy in June 2018 with the later Northgrippian and Meghalayan Ages/Stages. The lower boundary of the Greenlandian Age is the GSSP sample from the North Greenland Ice Core Project in central Greenland (75.1000°N 42.3200°W). The Greenlandian GSSP has been correlated with the end of Younger Dryas The Younger Dryas (YD, Greenland Stadial GS-1) was a period in Earth's geologic history that occurred circa 12,900 to 11,700 years Before Present (BP). It is primarily known for the sudden or "abrupt" cooling in the Northern Hemisphere, when the ... (from near-glacial to int ...

South Asia
South Asia is the southern Subregion#Asia, subregion of Asia that is defined in both geographical and Ethnicity, ethnic-Culture, cultural terms. South Asia, with a population of 2.04 billion, contains a quarter (25%) of the world's population. As commonly conceptualised, the modern State (polity), states of South Asia include Bangladesh, Bhutan, India, the Maldives, Nepal, Pakistan, and Sri Lanka, with Afghanistan also often included, which may otherwise be classified as part of Central Asia. South Asia borders East Asia to the northeast, Central Asia to the northwest, West Asia to the west and Southeast Asia to the east. Apart from Southeast Asia, Littoral South Asia, Maritime South Asia is the only subregion of Asia that lies partly within the Southern Hemisphere. The British Indian Ocean Territory and two out of Atolls of Maldives, 26 atolls of the Maldives in South Asia lie entirely within the Southern Hemisphere.

Ruminant
Ruminants are herbivorous grazing or browsing artiodactyls belonging to the suborder Ruminantia that are able to acquire nutrients from plant-based food by fermenting it in a specialized stomach prior to digestion, principally through microbial actions. The process, which takes place in the front part of the digestive system and therefore is called foregut fermentation, typically requires the fermented ingesta (known as cud) to be regurgitated and chewed again. The process of rechewing the cud to further break down plant matter and stimulate digestion is called rumination. The word "ruminant" comes from the Latin ''ruminare'', which means "to chew over again". The roughly 200 species of ruminants include both domestic and wild species. Ruminating mammals include cattle, all domesticated and wild bovines, goats, sheep, giraffes, deer, gazelles, and antelopes.Fowler, M.E.

Grazing (behaviour)
Grazing is a method of eating, feeding in which a herbivore feeds on low-growing plants such as grasses or other multicellular organisms, such as algae. Many species of animals can be said to be grazers, from large animals such as Hippopotamus, hippopotamuses to small aquatic Snail, snails. Grazing Ethology, behaviour is a type of List of feeding behaviours, feeding strategy within the ecology of a species. Specific grazing strategies include Graminivore, graminivory (eating grasses); coprophagy (producing part-digested pellets which are reingested); pseudoruminant (having a multi-chambered stomach but not chewing the cud); and grazing on plants other than grass, such as on marine algae. Grazing's ecological effects can include redistributing nutrients, keeping grasslands open or favouring a particular species over another. Ecology Many small selective herbivores follow larger grazers which skim off the highest, tough growth of grasses, exposing tender shoots. For terrestrial a ...

Pelorovis
''Pelorovis'' ("prodigious/monstrous sheep") is an extinct genus of African bovines which existed during the Pleistocene epoch. Originally believed to be a giant member of Caprinae, related to modern sheep, it is now known to be a relative of cattle and buffalos. The best known and type species is ''Pelorovis oldowayensis'', from the Early Pleistocene of Olduvai Gorge, Tanzania, though two others, ''P. turkanensis'' and ''P. howelli'', are currently recognised. A fourth, ''P. praeafricanus'', may exist, or it may represent the same species as ''P. oldowayensis''. "''Pelorovis''" ''antiquus'', from the Late Pleistocene-Holocene, and "P." ''kaisensis'', have since been moved into '' Syncerus'', the same genus as living African buffalo. In many respects, ''Pelorovis'' resembles the modern cattle genus, '' Bos'', and has been compared morphologically to aurochsen (''Bos primigenius''). It has been suggested that they represent the same genus, in which case ''Pelorovis'' would be a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different varieties, subspecies, species or genera through sexual reproduction. Generally, it means that each cell has genetic material from two different organisms, whereas an individual where some cells are derived from a different organism is called a chimera. Hybrids are not always intermediates between their parents such as in blending inheritance (a now discredited theory in modern genetics by particulate inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridization, which include genetic and morph ...

Bhimbetka
The Bhimbetka rock shelters are an archaeological site in central India that spans the Paleolithic and Mesolithic periods, as well as the historic period. It exhibits the earliest traces of human life in India and evidence of the Stone Age starting at the site in Acheulean times. It is located in the Raisen district in the Indian state of Madhya Pradesh, about south-east of Bhopal. It is a UNESCO World Heritage Site that consists of seven hills and over 750 rock shelters distributed over .Javid, Ali and Javeed, Tabassum (2008), ''World Heritage Monuments and Related Edifices in India'', Algora Publishing, 2008, pages 15–19 At least some of the shelters were inhabited more than 100,000 years ago. The rock shelters and caves provide evidence of human settlement and the cultural evolution from hunter-gatherers to agriculture, and expressions of prehistoric spirituality. Some of the Bhimbetka rock shelters feature prehistoric cave paintings and the earliest are dated to 10,0 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bengal
Bengal ( ) is a Historical geography, historical geographical, ethnolinguistic and cultural term referring to a region in the Eastern South Asia, eastern part of the Indian subcontinent at the apex of the Bay of Bengal. The region of Bengal proper is divided between the modern-day sovereign nation of Bangladesh and the States and union territories of India, Indian states of West Bengal, and Karimganj district of Assam. The ancient Vanga Kingdom is widely regarded as the namesake of the Bengal region. The Bengali calendar dates back to the reign of Shashanka in the 7th century CE. The Pala Empire was founded in Bengal during the 8th century. The Sena dynasty and Deva dynasty ruled between the 11th and 13th centuries. By the 14th century, Bengal was absorbed by Muslim conquests in the Indian subcontinent. An independent Bengal Sultanate was formed and became the eastern frontier of the Islamic world. During this period, Bengal's rule and influence spread to Assam, Arakan, Tri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
