Antelope are not a cladistic or taxonomically defined group.
The term is used to describe all members of the family Bovidae that do not fall under the category of sheep, cattle, or goats.
The 91 species, most of which are native to Africa, occur in about 30 genera.
The classification of tribes or subfamilies within Bovidae is still a matter of debate, with several alternative systems proposed.
Antelope are ruminants, so have well-developed molar teeth, which grind cud (food balls stored in the stomach) into a pulp for further digestion.
They have no upper incisors, but rather a hard upper gum pad, against which their lower incisors bite to tear grass stems and leaves.
An antelope is a member of a number of even-toed ungulate species indigenous to various regions in Africa and Eurasia.
Antelopes comprise a wastebasket taxon (miscellaneous group) within the family Bovidae, encompassing those Old World species that are not cattle, sheep, buffalo, bison, or goats; even so, antelope are generally more deer-like than other bovids. The English word "antelope" first appeared in 1417 and is derived from the Old French antelop, itself derived from Medieval Latin ant(h)alopus, which in turn comes from the Byzantine Greek word anthólops, first attested in Eustathius of Antioch (circa 336), according to whom it was a fabulous animal "haunting the banks of the Euphrates, very savage, hard to catch and having long, saw-like horns capable of cutting down trees".With some species possessing spectacular leaping and evasive skills, individuals may escape.Texas in particular has many game ranches, as well as habitats and climates, that are very hospitable to African and Asian plains antelope species. However, many species are more secluded, such as the forest antelope, as well as the extreme cold-living saiga, the desert-adapted Arabian oryx, the rocky koppie-living klipspringer, and semiaquatic sitatunga.Usually, all species of the Alcelaphinae, Antilopinae, Hippotraginae, Reduncinae, Cephalophinae, many Bovinae, the grey rhebok, and the impala are called antelopes.No antelope species is native to Australasia or Antarctica, nor do any extant species occur in the Americas, though the nominate saiga subspecies occurred in North America during the Pleistocene.India is home to the nilgai, chinkara, blackbuck, Tibetan antelope, and four-horned antelope, while Russia and Central Asia have the Tibetan antelope, and saiga.
