The birth of Darwin’s theory of evolution unified various disciplines of biology and provided biological research with the first scientific theory that could be used for prediction and testing. From then on, the study of biology was no longer just a matter of simple data collection. , chaotic biological phenomena also have rules to follow. The study of biological phenomena has changed from natural history to science, and biological science was born. The great biologist Dubzhansky once said a famous saying: "Without the light of evolution, biology makes no sense." Without the theory of evolution, there is no biology. Darwin's theory of evolution also brought a subversive revolution to the humanities. Before Darwin, people generally believed that man was the spirit of all things, not a part of nature, but beyond nature. For example, Judeo-Christian theology regards human beings as special works created by God according to his own image. Among all things in the world, only human beings are endowed with souls, and everything in the world is created to serve humans.
