| Equus caballus|
Horses are mammals of the family Equidae. The common horse is the species Equus caballus. It was domesticated from wild horses by humans at least 5000 years ago. They gallop up to 30 miles an hour. Horses are also known as amazing jumpers and racers.
A male horse is a stallion, and a female horse is a mare. The general term for a young horse is foal. A young female horse is a filly, and a young male horse is a colt. A castrated horse is a gelding.horses are nearly
all around the world.
The evolution of horses has been well studied. Fifty million years ago, there were no horses as we know them now. Of the earliest fossil horse, the North American one is called Eohippus, and the Eurasian one is called Hyracotherium. Both were small animals: Eohippus was the larger of the two at twice the size of a terrier dog.
Many changes took place between those little animals and today's horse. These changes are best explained as adaptations to its changing life-style. From a small forest-dweller eating nuts and fruit to a larger forest browser eating leaves and small branches. Finally, the modern horse is a grazer on open grassland, with different teeth, legs for running and much larger size. Major changes happened in the mid-Miocene when the climate became cooler, and grassland began to replace forests. This change continued, and several groups of mammals changed from browsers to grazers.
Horses and humans
They are used for riding, as transport, racing, and just plain riding. They are also used for carrying things or pulling carts, or to help plow farmer's fields in agriculture. Horses have also been used for meat, milk, and glue. Today, horses are mostly used for entertainment and sports. They are also still used for work and transportation in some places.
"Equus" is the old Latin word for horse.
Horses are used by humans in equine sports such as cross-country, showjumping, dressage, horse polo, rodeo events etc. Showjumping, cross-country and dressage are Olympic sports can be competed together in one event (known as one/three day events) or as separate events
Other uses of horses
Horsehide is a tough leather made from the skin of horses. Horsehair is used to make a stiff fabric. Horsehair can also be used as a stuffing for furniture. Horsehair can be mixed with plaster to make it strong.
Horses are used all over the world to carry people and pull carts.
