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.

Bos taurus (or Bos taurus taurus), typically referred to as "taurine" cattle, are generally adapted to cooler climates and include almost all cattle breeds originating from Europe and northern Asia. In some parts of the world further species of cattle are found (both as wild and domesticated animals), and some of these are related so closely to ...
Cattle were originally identified as three separate species: Bos taurus, the European or "taurine" cattle (including similar types from Africa and Asia); Bos indicus, the Indicine or "zebu"; and the extinct Bos primigenius, the aurochs. The aurochs is ancestral to both zebu and taurine cattle. [74]
Bos (from Latin bōs: cow, ox, bull) is a genus of bovines, which includes, among others, wild and domestic cattle.. Bos is often divided into four subgenera: Bos, Bibos, Novibos, and Poephagus, but including these last three divisions within the genus Bos without including Bison is believed to be paraphyletic by many workers on the classification of the genus since the 1980s.
The Droughtmaster is an Australian breed of beef cattle. It was developed from about 1915 in North Queensland by crossing zebuine cattle with cattle of British origin, principally the Beef Shorthorn. It was the first Australian taurindicine hybrid breed; [3]: 171 it is approximately 50% Bos indicus and 50% Bos taurus. [4]
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.

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 ...
Boran cattle are a popular Zebu beef breed in eastern Africa. [2]Through DNA sampling, Hanotte et al. have analyzed the genetic make-up of the Boran and it consists of the following genetic proportions—64% Bos indicus, 24% European Bos taurus and 12% African Bos taurus.
