Prehistoric Horses Use to Have Five Toes Per Foot


Did you know that the first horse was about the size of a pet cat?

About 50 million years ago, an eight-inch horse called Hyracotherium lived in the forest and woods of Europe, Asia, and North America.

Early horses began to get bigger once they started eating grass. This is because grass and open plains did not appear on Earth until 25 million years ago.

At first, horses had five toes per foot but they slowly began losing them as they evolved. Hyracotherium had four toes on each front foot and three on each of their back foot. Mesohippus, a later evolution of the horse, was as big as a Labrador dog and had three toes on each foot. Horses now have one toe on each foot that end in a large hoof.

Over the years, horses have changed. Now, they eat grass and rather than having five toes on each foot, they have one. Who knows what will change about them next?
