Looking back at our evolutionary history, we will find that human beings originated from African apes and evolved into modern humans after millions of years. The road of human evolution can be described as long and arduous. While struggling with nature, human ancestors adapted to nature, strengthened their limbs, developed languages and learned to make tools. Agriculture and animal husbandry have also appeared one after another, and human beings have created many beautiful works of art ... and eventually become the winners of natural selection.
