The earliest horses had three or four functional toes. But over millions of years of evolution, many horses lost their side toes and developed a single hoof. Only horses with single-toed hooves survive today, but the remains of tiny vestigial toes can still be found on the bones above their hoofs.
Why do horses not have toes?
How horses—whose ancestors were dog-sized animals with three or four toes—ended up with a single hoof has long been a matter of debate among scientists. Now, a new study suggests that as horses became larger, one big toe provided more resistance to bone stress than many smaller toes.
How did horses lose their toes?
‘ Horses are the only creature in the animal kingdom to have a single toe – the hoof, which first evolved around five million years ago.
