Horse and foal

The horse (Equus ferus caballus) is a domesticated, one-toed, hoofed mammal. It belongs to the taxonomic family Equidae and is one of two extant subspecies of Equus ferus. The horse has evolved over the past 45 to 55 million years from a small multi-toed creature, close to Eohippus, into the large, single-toed animal of today. Humans began domesticating horses around 4000 BCE, and their domestication is believed to have been widespread by 3000 BCE. Horses in the subspecies caballus are domesticated, although some domesticated populations live in the wild as feral horses. These feral populations are not true wild horses, which are horses that never have been domesticated and historically linked to the megafauna category of species. There is an extensive, specialized vocabulary used to describe equine-related concepts, covering everything from anatomy to life stages, size, colors, markings, breeds, locomotion, and behavior.

Horses are adapted to run, allowing them to quickly escape predators, and possess a good sense of balance and a strong fight-or-flight response. Related to this need to flee from predators in the wild is an unusual trait: horses are able to sleep both standing up and lying down, with younger horses tending to sleep significantly more than adults. Female horses, called mares, carry their young for approximately 11 months and a young horse, called a foal, can stand and run shortly following birth. Most domesticated horses begin training under a saddle or in a harness between the ages of two and four. They reach full adult development by age five, and have an average lifespan of between 25 and 30 years.

Horse breeds are loosely divided into three categories based on general temperament: spirited "hot bloods" with speed and endurance; "cold bloods", such as draft horses and some ponies, suitable for slow, heavy work; and "warmbloods", developed from crosses between hot bloods and cold bloods, often focusing on creating breeds for specific riding purposes, particularly in Europe. There are more than 300 breeds of horse in the world today, developed for many different uses. (Full article...)

Skeletal anatomy of a horse

The limbs of the horse are structures made of dozens of bones, joints, muscles, tendons, and ligaments that support the weight of the equine body. They include two apparatuses: the suspensory apparatus, which carries much of the weight, prevents overextension of the joint and absorbs shock, and the stay apparatus, which locks major joints in the limbs, allowing horses to remain standing while relaxed or asleep. The limbs play a major part in the movement of the horse, with the legs performing the functions of absorbing impact, bearing weight, and providing thrust. In general, the majority of the weight is borne by the front legs, while the rear legs provide propulsion. The hooves are also important structures, providing support, traction and shock absorption, and containing structures that provide blood flow through the lower leg. As the horse developed as a cursorial animal, with a primary defense mechanism of running over hard ground, its legs evolved to the long, sturdy, light-weight, one-toed form seen today.

Good conformation in the limbs leads to improved movement and decreased likelihood of injuries. Large differences in bone structure and size can be found in horses used for different activities, but correct conformation remains relatively similar across the spectrum. Structural defects, as well as other problems such as injuries and infections, can cause lameness, or movement at an abnormal gait. Injuries to and problems with horse legs can be relatively minor, such as stocking up, which causes swelling without lameness, or quite serious. Even leg injuries that are not immediately fatal may still be life-threatening to horses, as their bodies are adapted to bear weight on all four legs and serious problems can result if this is not possible.

The Namib Desert horse (Afrikaans: Namib Woestyn Perd) is a feral horse found in the Namib Desert of Namibia. It is the only feral herd of horses residing in Africa, with a population ranging between 90 and 150. The Namib Desert horse is athletic in appearance, resembling the European light riding horses from which it probably descends, and usually dark in color. Despite the harsh environment in which they live, the horses are generally in good condition, except during times of extreme drought. The horses have been the subject of several population studies, which have given significant insight into their population dynamics and ability to survive in desert conditions.

The origin of the Namib Desert horse is unclear, though several theories have been put forward. Genetic tests have been performed, although none to date have completely verified their origin. The most likely ancestors of the horses are a mix of riding horses and cavalry horses, many from German breeding programs, released from various farms and camps in the early 20th century, especially during World War I. Whatever their origin, the horses eventually congregated in the Garub Plains, near Aus, Namibia, the location of a man-made water source. They were generally ignored by humans, except for the periodic threat of eradication, due to the possibility that they were destroying native herbivore habitat, until the 1980s. In 1984, the first aerial survey of the population was made, and in 1986, their traditional grazing land was incorporated into the Namib-Naukluft Park. At several points, some horses have been removed from the herd, including the removal and sale of over one-third of the population in 1992. Since the early 1990s, close records of the population have been kept, and studies have been performed to determine the horses' effect on their environment. Despite being considered an exotic species within the park, they are allowed to remain due to their ties to the country's history and draw as a tourist attraction. (Full article...)
