Caprinae
A goat antelope is any of the 26 species of mostly medium-sized herbivores that make up the subfamily Caprinae or the single species in subfamily Panthalopinae. The domestic sheep and domestic goat are both part of the goat antelope group, and the group itself is part of the family Bovidae, which in other branches contains the antelopes and domestic cattle.
The goat antelope or caprid group is known from as early as the Miocene, but did not reach its greatest diversity until the recent ice ages, when many of its members became specialised for marginal, often extreme, environments: mountains, deserts, and the sub-Arctic region. In consequence, although most goat antelopes are gregarious and have a fairly stocky build, they diverge in many other ways. The Musk Ox became adapted to the extreme cold of the tundra; the Mountain Goat of North America specialised in very rugged terrain; the Urial, probable ancestor of modern Domestic Sheep, occupied a largely infertile area from Kashmir to Iran, including much desert country.
Many of the ice age species are now extinct, probably largely because of human interaction. Of the survivors, no less than 5 are classifed as endangered, 8 as vulnerable, 7 as of concern and needing conservation measures but at lower risk, and just 7 species are secure.
