the revolution of the horse

the revolution of the horse qLl7E

The picture gives some information about the evolution of the horse from its ancient Eohippus about a period of 40 million years. Overall, it is clear that its development goes through four stages and mainly takes place in foot and size. As can be seen from the picture, in the first step of this process 40 million years ago, the name of this species was Eohippus. At that time, its size was the smallest in evolution and the foot consisted of 5 toes. After 10 million years ago, it transformed into Mesohippus with a larger size and a fur on the back of his neck. Besides, one of the biggest changes to the horse is reduction in number to three, with one toe in the middle. Merychippus evolved 15 million years ago, the main change for this step involves bigger size and foot structure, thicker fur and longer tail. According to the figure, the last step of this process is the modern horses. In addition, it is the largest in this family line with complex feet structure, not only toenails are transformed into hooves but also the hair on the nape and tail is extremely different from previous generations.
