*there is a better answer*

-The first horse was called a Hyracotherium, or originally called Eohippus. it didn't look like the horse that we know today, it had 4 toes on each foot and it stood about 10 inches tall

- the second horse was called either Mesohippus , just a bit larger than Eohippus, they had longer legs and 3 toes instead of 4

-Merychippus (see Mesohippus).....gradually the Earth's dense, wet forests became firm, grassy plains, and to avoid extinction, the early horses had changed to.....

-the next horse was Pliohippus, it had large, flat grinding teeth for feeding on grass, and longer, stronger legs supported by hooves.

- then came the last horse that we all know today, Equus caballus! by the end of the ice age, millions of wild horses that we could now recognize today, roamed Europe and Asia.

Answer 2

The modern horse had ancestors that were quite small and five toed. They lived in forests and were browsers. The forest disappeared over time and the horses grew larger and their toes began to recede as grassland replace forest. They became grazers and their toes receded to one large middle toe that became the hoof.

Now we have a large, fleet animal that lives almost exclusively in grassland.

Answer 3

Over time, horses have evolved to be taller - the original 'horse' from just after the extinction of the dinosaurs was about the size of a beagle. Also, horses used to have five toes. Over the millenia horses have dropped from five toes, to three, to the one seen today.
