(Equus ferus caballus
) is a hoofed (ungulate
, a subspecies of one of seven extant species of the family Equidae
. The horse has evolved
over the past 45 to 55 million years from a small multi-toed creature into the large, single-toed
animal of today. Humans began to domesticate
horses around 4000 BC, and their domestication
is believed to have been widespread by 3000 BC; by 2000 BC the use of domesticated horses had spread throughout the Eurasian
continent. Although most horses today are domesticated, there are still populations of wild
and feral horses
. There are over 300 breeds of horses in the world today, developed for many different uses.
The horses anatomy enables them to make use of speed to escape predators and they have a well-developed sense of balance and a strong fight-or-flight instinct. 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. Horses and humans interact in many ways, including a wide variety of sport competitions, non-competitive recreational pursuits and working activities. A wide variety of riding and driving techniques have been developed, using many different styles of equipment and methods of control. Many products are derived from horses, including meat, milk, hide, hair, bone, and pharmaceuticals extracted from the urine of pregnant mares.
Easy Jet was an American Quarter Horse foaled, or born, in 1967, and was one of only two horses to have been a member of the American Quarter Horse Association (or AQHA) Hall of Fame as well as being an offspring of members. Easy Jet won the 1969 All American Futurity, the highest race for Quarter Horse racehorses, and was named World Champion Quarter Race Horse in the same year. He earned the highest speed rating awarded at the time—AAAT. After winning 27 of his 38 races in two years of racing, he retired from the track and became a breeding stallion.
As a sire, or father, he was the first All American Futurity winner to sire an All American Futurity winner, and went on to sire three winners of that race, and nine Champion Quarter Running Horses. Ultimately, his ownership and breeding rights were split into 60 shares worth $500,000 each—a total of $30 million. By 1993, the year after his death, his foals had earned more than $25 million on the racetrack.
is a horse breed
best known for its use in horse racing
. Although the word "thoroughbred" is sometimes used to refer to any breed of purebred
horse, it technically refers only to the Thoroughbred breed. Thoroughbreds are considered a "hot-blooded
" horse, known for their agility, speed and spirit.
The Thoroughbred as it is known today was first developed in 17th and 18th century England, when native mares were crossbred with imported Arabian stallions. All modern Thoroughbreds can trace their pedigrees to three stallions originally imported into England in the 1600s and 1700s, and to 74 foundation mares of English and Oriental (Arabian or Barb) blood. During the 1700s and 1800s, the Thoroughbred breed spread throughout the world; they were imported into North America starting in 1730 and into Australia, Europe, Japan and South America during the 1800s. Millions of Thoroughbreds exist worldwide today, with over 118,000 foals registered each year worldwide.
Thoroughbreds are used mainly for racing, but are also bred for other riding disciplines, such as show jumping, combined training, dressage, polo, and fox hunting. They are also commonly cross-bred with other breeds to create new breeds or to improve existing ones, and have been influential in the creation of many important breeds, such as the Quarter Horse, the Standardbred, the Anglo-Arabian, and various Warmblood breeds.
