A goat-antelope or caprid is any of the species
Species
In biology, a species is one of the basic units of biological classification and a taxonomic rank. A species is often defined as a group of organisms capable of interbreeding and producing fertile offspring. While in many cases this definition is adequate, more precise or differing measures are...

In biological classification, family is* a taxonomic rank. Other well-known ranks are life, domain, kingdom, phylum, class, order, genus, and species, with family fitting between order and genus. As for the other well-known ranks, there is the option of an immediately lower rank, indicated by the...

A ruminant is a mammal of the order Artiodactyla that digests plant-based food by initially softening it within the animal's first compartment of the stomach, principally through bacterial actions, then regurgitating the semi-digested mass, now known as cud, and chewing it again...

, probably largely because of human interaction. Of the survivors:
  • Five are classified as endangered,
  • Eight as vulnerable,
  • Seven as of concern and needing conservation measures, but at lower risk, and
  • Seven species are secure.


Members of the group vary considerably in size, from just over 1 metres (3.3 ft) long for a full-grown grey goral
Nemorhaedus
The gorals are four species in the genus Nemorhaedus or Naemorhedus. They are small ungulates with a goat-like or antelope-like appearance....

 (Nemorhaedus goral), to almost 2.5 metres (8.2 ft) long for a musk ox, and from under 30 kilograms (66.1 lb) to more than 350 kilograms (771.6 lb). Musk oxen in captivity have reached over 650 kilograms (1,433 lb).

The lifestyles of caprids fall into two broad classes, resource-defenders which are territorial and defend a small, food-rich area against other members of the same species; and grazers, which gather together into herds and roam freely over a larger, usually relatively infertile area.

The resource-defenders are the more primitive group: they tend to be smaller in size, dark in colour, males and females fairly alike, have long, tassellated ears, a long mane, and dagger-shaped horns. The grazers (sometimes collectively known as tsoan caprids, from the Semitic tso'wn meaning "to migrate") evolved more recently. They tend to be larger, highly social, and rather than mark territory with scent glands, they have highly evolved dominance behaviours. There is no sharp dividing line between the groups, but a continuum between the serows at one end of the spectrum and sheep, true goats, and musk oxen at the other.

Evolution

The goat-antelope or caprid group is known from as early as the Miocene
Miocene
The Miocene is a geological epoch of the Neogene Period and extends from about . The Miocene was named by Sir Charles Lyell. Its name comes from the Greek words and and means "less recent" because it has 18% fewer modern sea invertebrates than the Pliocene. The Miocene follows the Oligocene...
