There are 1.3 billion cows in the planet today. In 2009, cow became the primary livestock animal to have its chromosomes mapped. Cows were initially recognized by Carolus Linnaeus as three separate species. These were Bos Taurus, the European or taurine cattle. Bos indicus, the zebu and the extinct Bos primigenius, the aurochs are some species of these types of animals. The aurochs cows are parent to both zebu and taurine cows. More lately these three have increasingly been grouped as one class of cows, with Bos primigenius Taurus, Bos primigenius indicus and Bos primigenius primigenius as the subspecies of these types of animals.
Complicating the topic is the ability of cow to interbreed with other directly related species. Mixture individuals and even breeds survive, not only between taurine cow and zebu but also between one or both of these and some other members of the genusBos. Hybrid cows can also occur between taurine cow and either species of bison, which some authors consider to be in the type Bos as well. The hybrid source of some types of animals may not be clear. The example being genetic testing of the Dwarf Lulu breed, the only hump less taurine type cattle in Nepal. Cattle cannot effectively be hybridized with more vaguely related groups such as water buffalo or African buffalo.

Cows also known as cattle are the most ordinary type of big domestic ungulates. They are a famous modern part of the subfamily Bovinae. Cows are the most extensive species of the genus Bos. They are mainly usually classified together as Bos primi genius. Cows are raised as livestock for meat, as dairy animals for milk and other dairy goods. They are also used as draft animal for pulling carts and plows. Others include leather and dung for fertilizer or fuel. In India, cows are considered sacred.
