The Indian aurochs [b] (Bos primigenius namadicus; Sindhi: انڊين جهنگلي ڏاند) 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. [1]
The aurochs (Bos primigenius) (/ ˈ ɔː r ɒ k s / or / ˈ aʊ r ɒ k s /, plural aurochs or aurochsen) is an extinct species of bovine, considered to be the wild ancestor of modern domestic cattle. With a shoulder height of up to 180 cm (71 in) in bulls and 155 cm (61 in) in cows, it was one of the largest herbivores in the Holocene ; it had ...
Both scientific names Bos taurus and Bos indicus were introduced by Carl Linnaeus in 1758, with the latter used to describe humped cattle in China. [3]The zebu was classified as a distinct species by Juliet Clutton-Brock in 1999, [8] but as a subspecies of the domestic cattle, Bos taurus indicus, by both Clutton-Brock and Colin Groves in 2004 [9] and by Peter Grubb in 2005.

The age of Earth is about 4.54 billion years; [7] [33] [34] the earliest undisputed evidence of life on Earth dates from at least 3.5 billion years ago according to the stromatolite record. [35] Some computer models suggest life began as early as 4.5 billion years ago. [36] [37] The oldest evidence of life is indirect in the form of isotopic ...
The earliest evidence for life on Earth includes: 3.8 billion-year-old biogenic hematite in a banded iron formation of the Nuvvuagittuq Greenstone Belt in Canada; [30] graphite in 3.7 billion-year-old metasedimentary rocks in western Greenland; [31] and microbial mat fossils in 3.48 billion-year-old sandstone in Western Australia.
Cattle have the largest biomass of any animal species on Earth, at roughly 400 million tonnes, followed closely by Antarctic krill at 379 million tonnes and humans at 373 million tonnes. [96] In 2023, the countries with the most cattle were India with 307.5 million (32.6% of the total), Brazil with 194.4 million, and China with 101.5 million ...
A group of Asian indicine cattle ("Zebu", Bos taurus indicus) split off in around 700 AD (around the time of Islamization of the East African coast) and mingled with African taurines in different ratios, producing the four groups of African humped cattle. In Kim's own analysis, African taurines gained key adaptations in 16 genes for immunity ...
The Southern Yellow is a group of cattle breeds distributed in southern China. It is one of the three principal groups within the overall Chinese Yellow cattle population, which includes all indigenous Chinese cattle of both Bos taurus and Bos indicus origin, as well as hybrids between the two species; Chinese people traditionally do not distinguish between these.
