What did Horses Look Like Millions of Years ago?

Now and then, it's fun to tell you some interesting facts about horses. Do you think they always looked the way they do today? If you're thinking they haven't changed at all, you'd be mistaken. For example, millions of years ago, horses were about the size of a large dog. Instead of having rounded hooves, or feet, as they do today, they had toes! There were three long toes and the hind feet and four on the front feet. Each toe had a tiny hoof. Wouldn't it feel strange having feet with different numbers of toes? Over thousands of years, the separate toes wore off so that horses had the hoof they have today.
What kind of diet did horses enjoy thousands of years ago? They ate small shrubs and trees, along with grass. It doesn't sound too appetizing to us, but they thrived on it.
Who discovered that horses were good workers? It was the Chinese. They found out that horses could work hard and very reliable on rocky surfaces. They used them as pack animals. Later on, they deduced that it would be much more comfortable for them to have something to sit on, besides the horse's back. They designed a saddle. There was still a problem, though. They couldn't direct the horse anywhere, so they designed a bridle, which allowed them to steer the horse. After that, they used horses in battles. The Chinese were very clever, don't you think?
