Text 4 Natural Selection and Horse Evolution.
The evolution of the horse involves the gradual development of the modern horse from the fox-sized, forest-dwelling Eohippus. Paleozoologists have been able to piece together a more complete picture of the modern horse's evolutionary lineage than that of any other animal. Eohippus, which lived 70 million years ago, was a small animal. This group of animals appears to have been originally specialized for life in tropical forests. They had small body structure, small teeth, and short legs with 4 toes on each front leg and 3 toes on each hind leg which were beneficial for walking on the soft, moist grounds of primeval forests. The heavy plant growth provided these prehistoric horses a cover for protection from predators and plenty of food to eat. As millions of years passed, the lush forest began to disappear and thin out. The lush tropical forest was gradually replaced by grassland with dry hard soil. The horse’s predecessors’ diets shifted from soft foliage to harder grasses. At the same time, as the plains began to appear, the horse's predecessors needed to be able to escape predators, since they no longer had the dense forest to hide in.
