Horse is one of two extant subspecies of Equus ferus. It is an odd-toed ungulate mammal belonging to the taxonomic family Equidae. The horse has evolved over the past 45 to 55 million years from a small multi-toed creature, Eohippus, into the large, single-toed animal of today. Humans began domesticating horses around 4000 BC, and their domestication is believed to have been widespread by 3000 BC. 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, as this term is used to describe horses that have never been domesticated, such as the endangered Przewalski’s horse, a separate subspecies, and the only remaining true wild horse. 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’ 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 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 saddle or in 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. — Wikipedia

- Ancient horse DNA reveals gene flow between...on May 18, 2021 at 5:08 pm
A new study of ancient DNA from horse fossils found in North America and Eurasia shows that horse populations on the two continents remained connected through the Bering Land Bridge, moving back and forth and interbreeding multiple times over hundreds of thousands of years.
- Horse remains reveal new insights into how Native...on February 4, 2021 at 6:14 pm
When a Utah couple dug up the remains of a horse near the city of Provo, researchers suspected that they may have discovered an animal that lived during the last Ice Age. New results suggest a different story.

Climate warming is linked to a widening interval between leaf unfolding and flowering in European trees, with implications for tree fitness and the wider environment, according to new research.
- Central Asian horse riders played ball games...on October 12, 2020 at 2:31 pm
Researchers have investigated ancient leather balls discovered in the graves of horse riders in northwest China. According to the international research team, they are around 3,000 years old, making them the oldest balls in Eurasia. The find suggests amongst others that the mounted warriors of Central Asia played ball games to keep themselves fit.

In an anatomical comparison of the third metacarpal, or cannon bone, among Thoroughbred racehorses, American Quarter Horses and feral Assateague Island ponies, researchers have found that fostering adaptations in these bones through training might help horses better endure the extreme conditions of racing and prevent serious, often life-ending injuries on the track.

A new study, led by University of Minnesota Twin Cities engineering researchers, shows that the stiffness of protein fibers in tissues, like collagen, are a key component in controlling the movement of cells. The groundbreaking discovery provides the first proof of a theory from the early 1980s and could have a major impact on fields that study cell movement from regenerative medicine to cancer research.
- Stone tool tells the story of Neanderthal huntingon July 22, 2021 at 1:59 pm
65,000 years ago Neanderthal from the Swabian Jura hunted horses and reindeer with hafted leaf-shaped stone points. A newly discovered leaf point from the UNESCO World Heritage site of Hohle Fels Cave documents the evolution of hunting. A team under the direction of Professor Nicholas Conard for the University of Tübingen and the Senckenberg Centre for Human Evolution and Palaeoenvironment in southern Germany recovered the artifact underlying a layer dating to 65,000 years ago, which […]
- Faster diagnosis of deadly Hendra virus in horseson July 20, 2021 at 11:59 am
University of Queensland vets are diagnosing the deadly Hendra virus in horses faster than ever, developing a diagnostic point-of-care kit that can detect the pathogen in under an hour, rather than days.
- A novel approach for developing new antibioticson July 19, 2021 at 3:16 pm
Researchers at Children's Hospital of Philadelphia (CHOP) have developed a novel method for producing new antibiotics to combat resistant bacteria. Through an approach that would target bacteria with an antibiotic that is masked by a prodrug, which the bacteria would themselves remove, the researchers identified a method that would allow for development of new, effective antibiotics that could overcome issues of resistance. The findings were published today in eLife.
