answer. Actually horses did have toes over the years the earth changed and the horse aka Equis Caballis had 4 toes but over a trial of millions of years they grew to 4 toes, which is now a hoof and. each leg, horses, like all mammals, started out with five toes. The modern horse currently stands on "tip-toe" on the end of the toenail of the middle toe. The other 4 toes have become vestigial.
January 24, Seabiscuit, Secretariat and every nag to ever pull a plough had five toes on each foot, says a study released Wednesday that stomps on the notion modern horses only have one toe. Scientists have long assumed that horses, zebras and other equines gradually lost their digits over millions of years of evolution until all that was left—uniquely among mammals—was a great big middle toe ending in a hoof.
That assumption is at least partially wrong, according to the study, published in the journal Royal Society Open Science. The phantom fingers are not visible to the naked eye, but an examination of bones, fossils, and arteries in embryos revealed traces of the toes thought to have vanished over time, he told AFP. Scientists agree that humans, horses and other mammals are descendants of a common, distant ancestor with five fingers per limb.
But when subtropical forests gave way some 35 million years ago to savannahs with hard compact ground, the anatomy of squat, three- and four-toed horses adapted. By about nine million years ago, equine forest browsers had mostly given way to grass-eating grazers whose central digit had changed into a long bone above the hoof, known as the metacarpal. Some scientists acknowledge that small splints on the outer edges of the metacarpal in modern horses are remnants of the second and fourth digits, but argue that the equivalent of the little toe and thumb—digits 1 and 5—have entirely disappeared.
But a closer look at bone structure in modern horses revealed ridges on the back of the splints corresponding to these outer-most toes, the study argued. The researchers also traced the gradual metamorphosis of equine limbs over 55 million years of evolution, showing that the digits had merged. Even more revealing, dissections of foetal and adult horses uncovered a neurovascular network consistent with five digits, not one.

Silhouettes show Mesohippus primigenium, an early ancestor of the modern horse that lived 40 million years ago and was previously believed to have three toes, and the modern horse.
Photographs of both animals' hand bones appear alongside renderings of the researchers' proposed digit identities. Back view of 40 million-year-old Mesohippus' metacarpal. While three fully formed toes are visible, the researchers contend that ridges on the side of the toes represent the two missing digits, and that therefore, all 5 digits are expressed. Bottom of fossilized forelimb with five surfaces of differing texture, which suggests five digits are still present on today's horse.
