Donkey The donkey or ass, Equus africanus asinus,[1][2] is a domesticated member of the Equidae or horse family. The wild ancestor of the donkey is the African wild ass, E. africanus. The donkey has been used as a working animal for at least 5000 years. There are more than 40 million donkeys in the world, mostly in underdeveloped countries, where they are used principally as draught or pack animals. Working donkeys are often associated with those living at or below subsistence levels. Small numbers of donkeys are kept for breeding or as pets in developed countries. A male donkey or ass is called a jack, a female a jenny or jennet;[3][4][5] a young donkey is a foal.[5] Jack donkeys are often used to produce mules. Asses were first domesticated around 3000 BC,[6] or 4000 BC, probably in Egypt or Mesopotamia,[7] and have spread around the world. They continue to fill important roles in many places today. While domesticated species are increasing in numbers, the African wild ass and another relative, the Onager, are endangered. As beasts of burden and companions, asses and donkeys have worked together with humans for millennia. Scientific and common names Traditionally, the scientific name for the donkey is Equus asinus asinus based on the principle of priority used for scientific names of animals. However, the International Commission on Zoological Nomenclature ruled in 2003 that if the domestic species and the wild species are considered subspecies of each other, the scientific name of the wild species has priority, even when that subspecies was described after the domestic subspecies.[2] This means that the proper scientific name for the donkey is Equus africanus asinus when it is considered a subspecies, and Equus asinus when it is considered a species. At one time, the synonym ass was the more common term for the donkey, as in jackass, meaning "male donkey".
