Equine (sometimes also known as horse family) is the dominant species of the equine and related animal taxonomy, comprising existing horse, donkey and zebra, and many other species known only from fossil sources. The existing species all belong to the Equus group. Equids belong to the order Perissodactyla, to which the surviving Tapir and rhinoceroses as well as several died out families belong.
Horse-eye means any member of this line, which includes all animals of the species. Some of the oldest known fossil records of thequidae date back to the early Eocene, 54 million years ago. Formerly, they were classified as the Hyracotherium species, but the species is no longer considered a member of this group.
Other species have been divided into different genus. The early equivalents were fox-sized creatures with three toe rear and four toe forefeet. Their brain complexities indicate that they were already attentive and smart animals. Later species decreased the number of cloves and evolved teeths that were better able to grind grass and other viscous herbal foods.
