Donkey

The donkey, also known as the ass, is a domesticated equine animal. It is a member of the genus Equus, which includes horses and zebras. Scientists classify the donkey either as its own species, Equus asinus, or as a subspecies of the African wild ass, Equus africanus asinus.

These animals are incredibly important to human history and global economies. Today, there are more than 40 million donkeys living across the world. Most of these animals live in underdeveloped countries. In these regions, they serve as vital draught or pack animals to carry heavy loads.

Donkeys have several physical traits that help them survive in harsh environments. They are often found in marginal desert lands where other animals might struggle. One notable feature is their large ears. These ears help them pick up distant sounds in wide, open spaces. They also assist in cooling the donkey's blood. Most donkeys also possess primitive markings on their bodies. These are dark stripes on the shoulders and back that form a distinctive cross pattern.

To communicate across long distances, they use a loud vocalization called a bray. A single bray can last twenty seconds and be heard from over three kilometers away.

Understanding donkey biology involves looking at their specific roles and breeding. An adult male is called a jack or a jackass. An adult female is known as a jenny or a jennet. A baby, regardless of its sex, is called a foal.

Donkeys can also produce hybrid offspring through mating with horses. When a jack mates with a female horse, or mare, the result is a mule. If a male horse, called a stallion, mates with a jenny, the offspring is a hinny. These hybrids are distinct from purebred donkeys.

The history of the donkey is deeply tied to the development of human civilization. The ancestors of modern donkeys were the Nubian and Somalian subspecies of the African wild ass. It is believed that pastoral people in Nubia were the first to domesticate them. This happened long after humans domesticated sheep, goats, and cattle. Domestication allowed these cultures to become more mobile. Donkeys provided a great advantage because they do not need to spend time chewing cud like ruminants. This made them much more efficient for long-distance trade.

In ancient Egypt, donkeys were highly valued by the state and its citizens. During the Dynasty IV era, between 2675 and 2565 BC, some wealthy people owned more than 1,000 donkeys. They used them for agriculture, meat, dairy, and as pack animals. The importance of the animal is even seen in royal burials. In 2003, archaeologists excavated a tomb belonging to either King Narmer or King Hor-Aha. They discovered ten donkey skeletons buried with the same honors used for high-ranking humans.

Donkeys eventually spread across the entire globe through human movement. By the end of the fourth millennium BC, they had reached Southwest Asia. By 1800 BC, the main breeding center had moved to Mesopotamia. The region of Damascus became famous for breeding large, white riding asses. Later, the donkey reached Europe during the second millennium BC. They were likely brought there alongside the introduction of viticulture. This connection is seen in the association of the donkey with Dionysus, the Syrian god of wine.

In the Americas, donkeys arrived on the ships of Christopher Columbus in 1495. They were landed at Hispaniola during his second voyage. Later, animals reached Mexico and the United States through explorers like Juan de Zumárraga and Juan de Oñate. In the western United States, they became essential during the 19th-century Gold Rush. Many prospectors used the "burro" as their primary beast of burden. After the mining boom ended, many of these animals were abandoned. This led to the creation of feral populations, such as those found west of the Rocky Mountains.

Today, the global donkey population faces significant challenges and changes. In 2006, there were approximately 41 million donkeys worldwide. However, recent years have seen a rapid decline in these numbers. In China, the population dropped from 11 million to just 3 million by 2017. This is due to a high demand for donkey products, such as ejiao. This demand has put pressure on African populations as well. Some countries, like Kenya, have even opened abattoirs to meet this trade. Consequently, several African nations have banned the sale of donkey products to China to protect their animals.
