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

    on August 25, 2022 at 1:49 pm

    A new study shows that horses can be more reluctant in new situations if they have multiple riders, have had several owners or the horse has been with its current owner only for a short period of time. The results of the international research group that studied the interaction between horses and humans also indicate that it takes time to build a good interactive relationship with a horse.

    A Rutgers scientist aiming to help heal a sick horse created an ultra-sensitive DNA test that could have applications for difficult-to-detect illnesses in humans such as Lyme disease.

  • Ultrasound could save racehorses from bucked shins
    on August 9, 2022 at 6:12 pm

    When racehorses enter training at about 2 years old, they can develop tiny stress fractures and new bone formations in their legs. This condition, called bucked shin, occurs in about 70% of the animals. Researchers have now developed a method to screen for bucked shin using ultrasound. Axial transmission, in which an ultrasound emitter and receiver are placed on the skin to induce and measure wave velocities, is frequently used to study osteoporosis in humans. The method could detect bucked […]

    Feral horses have roamed freely across the island of Assateague off the coast of Maryland and Virginia for hundreds of years, but exactly how they got there has remained a mystery. In a new study, ancient DNA extracted from a 16th century cow tooth from one of Spain's first Caribbean colonies turns out to be from a horse. Analysis of the DNA suggest that old folk tales claiming that horses were marooned on Assateague following the shipwreck of a Spanish galleon are likely more fact than fiction.

  • Activated carbon could lead to odorless diapers
    on September 22, 2022 at 1:06 pm

    While activated carbon is used in kitchen fans to eliminate food odors, a new dissertation from the University of Gothenburg shows that activated carbon could also eliminate the smell of urine from diapers. Experiments with the odor molecule p-cresol show that activated carbon, which largely consists of the carbon variant graphene, can lock in odor instead of it being released to the surroundings.
