Equus (/ ˈɛkwəs, ˈiːkwəs /) [3] is a genus of mammals in the family Equidae, which includes horses, asses, and zebras. Within the Equidae, Equus is the only recognized extant genus, comprising seven living species. Like Equidae more broadly, Equus has numerous extinct species known only from fossils.

2025年4月8日 · Equus—the genus to which all modern equines, including horses, asses, and zebras, belong—evolved from Pliohippus some 4 million to 4.5 million years ago during the Pliocene. Equus shows even greater development of the spring mechanism in the foot and exhibits straighter and longer cheek teeth.

The horse (Equus ferus caballus) [2][5] 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, Eohippus, into the large, single-toed animal of today.

2019年12月17日 · Equus is the only surviving genus in the once diverse family of horses. Domesticated about 3,000 years ago, the horse had a profound impact on human history in areas such as migration, farming, warfare, sport, communication and travel.

The wild horse (Equus ferus) is a species of the genus Equus, which includes as subspecies the modern domesticated horse (Equus ferus caballus) as well as the endangered Przewalski's horse (Equus ferus przewalskii, sometimes treated as a separate species i.e. Equus przewalskii).

家马（学名：Equus caballus caballus、Equus ferus caballus）：是现存数量最多的奇蹄目成员，5000多年前被人类驯化为家畜，用于拉车、耕田、比赛、打仗等，经过改良和培育，已有200多个品种。

Equine, one of the mammal family of Equidae (order Perissodactyla) that includes the modern horses, zebras, and asses, as well as more than 60 species known only from fossils. All six modern members of the family are placed in the genus Equus. Only the races of E. caballus (including the myriad

Horses are un­gu­lates with an un­guligrade foot pos­ture, sin­gle-digit oval-shaped hooves, long tails, short hair, long slen­der legs, mus­cu­lar and deep torso build, long thick necks, and large elon­gated heads. The mane is a re­gion of coarse hairs, which ex­tends along the dor­sal side of the neck in both do­mes­tic and wild species.

Equus are odd-toed un­gu­lates with oval shaped hoofs. They fea­ture large and long heads with eyes fac­ing side­ways, as is char­ac­ter­is­tic with prey an­i­mals.

2025年4月7日 · Equus Simplicidens, resembling modern horses, appeared 3.5 million years ago. Tarpan, a prehistoric horse, is a domestic ancestor. Domestication began around 4000-3500 BC in the Eurasian Steppes. Early domestic horses were for milk, meat, and transport. Selective breeding in horses was and still is for traits like speed, strength, and temperament.
