Equidae

Also known as equids, equines, equid, equine

Equidae (commonly known as the horse family) is the taxonomic family of horses and related animals, including asses, zebras, and many extinct species known only from fossils. The family evolved more than 50 million years ago, in the Eocene epoch, from a small, multi-toed ungulate into larger, single-toed animals. All extant species are in the genus Equus, which originated in North America. Equidae belongs to the order Perissodactyla, which includes the extant tapirs and rhinoceros, and several extinct families. It is more specifically grouped within the superfamily Equoidea, the only other fam

AI overview

Equidae is the taxonomic family that includes horses, zebras, asses, and their extinct relatives, all of which evolved from a small, multi-toed ancestor over 50 million years ago into the single-toed animals we know today. This family matters because it demonstrates a well-documented example of how animal evolution occurred over millions of years, and its members have been significant to human societies as working animals and subjects of scientific study.

马科（学名：Equidae）是奇蹄目中的一科，史前种类曾经非常繁盛及多样化，现仅存马属一个属。虽然如此，马科动物依然是现存奇蹄目动物中种类数量最多，分布最广，最为人们所熟悉的。史前马科曾广泛分布于美洲、欧亚大陆和非洲，其中，美洲一直被视为马科的演化中心。现代马科分布于欧亚大陆和非洲，成员包括马、驴和斑马，大多数野生种都处于濒危状态。分類西藏野驴 Protorohippus †Haringtonhippus[1] †次马属 Epihippus †Haplohippus †Heptaconodon †Eohippus †Minippus †Orohippus †Pliolophus †Protorohippus †Sifrhippus †Eurohippus †Xenicohippus †原古马属 Propalaeotherium †安琪马亚科 Anchitheriinae[2] †Anchitherium †Archaeohippus †Desmatippus †Hypohippus †Kalobatippus †Megahippus †渐新马属 Mesohippus †中新马属 Miohippus †Parahippus †Sinohippus 马亚科 Equinae †草原古马属 Merychippus †Scaphohippus †Acritohippus †三趾马族 Hipparionini †Eurygnathohippus †三趾马属 Hipparion †Hippotherium †Nannippus †Neohipparion †Proboscidipparion †Pseudhipparion 馬族 Equini †星马属 Astrohippus †丽马属 Calippus †恐马属 Dinohippus 馬屬 Equus †南美土著马属 Hippidion †Onohippidium †Pliohippus †Protohippus †Heteropliohippus †Parapliohippus 参考文献 ^ Hay, Oliver P.
