Have you ever seen a horse with toes? Million of years ago .horses hadmany toes. They had four toes on each front foot. They had three toes on each back foot
These small horses lived in the forests. Their toes helped them run over the soft. wet ground.
It was once very hot in the forests. But the weather changed later It became cold. Many trees could not live in such cold weather. so they died and fell . Open fields took the place of forests. They made the ground dry and hard.
Horses began to get bigger with climate changing. on the dry. hard land. horses needed only their Middle toes for running. Their Middle toes became hard After a long time. horses had only one hard toe on each foot. We call it "hoof"
