The history of mankind is a history of continuous development from the realm of necessity to the realm of freedom. So is the history of natural science. Before the publication of the Origin of Species, many paleontologists believed that the life history of the earth was marked by a series of disasters. In their view, the species is fixed and the nature of the species is innate. Many people have expressed their opposition to this theory. For example, in Family History of Plants, Adelson opposed the theory of absolute fixation. Bufen is more committed to bridging the gap between species-domesticating wolves into dogs and cultivating rabbits into rabbits. However, this is not a good time to express new ideas. The Welsh paper "A white woman has a part of black skin", especially Lawrence's "Natural History of Human Beings" put forward the view that "the royal family and decadent aristocrats with poor spirits in Europe can be improved by" breeding according to species ",which offended the European rulers and faced the fate of being banned.

But the truth cannot be suppressed. After half a century of silence and indifference, the great Darwin's book The Origin of Species shocked the world like a volcanic eruption. The theory of natural selection in the Origin of Species is an epoch-making milestone in the history of natural science, and it is also the foundation of the theory of biological evolution. It not only opened a new era in the history of biological development, but also made the idea of evolution penetrate into all fields of natural science, played a great role in overcoming the mechanical materialism view of nature, caused great changes in the field of human thought, and had a wide and far-reaching impact in the course of world history. Because it not only provides sufficient evidence for biological evolution, but also expounds the mechanism of biological evolution reasonably, and explains the diversity and adaptability of biology reasonably and scientifically with the theory of natural selection, which has effectively attacked the argument that God created biology purposefully by using the diversity and adaptability of biology for a long time advocated by idealism and teleology. This is a great victory of the materialist world outlook. Marx and Engels spoke highly of Darwin's theory of evolution and regarded it as the natural science foundation of their own theory. Engels once pointed out: "There is another aspect of teleology that has not been refuted in the past, but it has been refuted now. In addition, there has never been such a large-scale attempt to prove the development of natural history and it has been so successful. " In fact, Darwin was successful. His success lies in his great investment in observation, and the silence and meditation of the ideological circle for half a century also contributed. Since18th century, the theory of evolution has gone through a tortuous development path for a whole century, and it didn't rise to the scientific law until the publication of the Origin of Species. In the days that followed, various ideas followed, and various hypotheses and theories kept popping up, but they were all carried out on the big stage built by Darwin.

Great works originate from great ideas, and the success of On the Origin of Species is not accidental. First of all, it is due to Darwin's advanced thought, which is also the same quality of every outstanding person who has brought great changes to human thought. /kloc-Europe in the 0/9th century, despite the rapid development of capitalism, people's thoughts have taken a big step forward because of the rise of the Renaissance. However, in the origin of biology, especially human beings, Europeans at that time were still at the primitive level of ignorance, and theology still occupied an absolute dominant position on this issue, because only it could provide a complete answer to this question. However, Darwin jumped out of the shackles of theology and found another answer to explain the origin of species outside theology.

The success of the Origin of Species is also inseparable from adequate preparation. Before Darwin, some advanced biologists tried to seek new explanations, but their preparations were not as good as Darwin's, so their explanations failed to form an organic system, which had an impact enough to shake the theoretical basis of theology, aroused people's thinking, and finally had a shocking impact on people at that time. In contrast, the preparation of the Origin of Species is much more adequate, and there is a core theory running through it, which makes the book on the Origin of Species form a unified whole. It is with this advantage that Origin of Species has achieved unprecedented success.

In addition, the success of On the Origin of Species is inseparable from the help of luck. It is often said that history makes heroes. Throughout the ages, how many talented people can only drown their sorrows by drinking and die old. Darwin was much luckier than them. Some biologists put forward the original viewpoint of species evolution as early as half a century ago, which laid the foundation for the publication of Darwin's Origin of Species. Half a century later, capitalism developed further. Although people did not openly oppose the theological explanation of biological origin, they drew a big question mark in their hearts. At this moment, only one person with enough knowledge and courage needs to stand up openly and undertake the mission of breaking the theological shackles of people's thoughts with a theory that is more in line with the facts. Darwin played this role. He smashed the old theological theory with the Origin of Species, so that later generations called the Origin of Species "a great work to expel God from the biological world".

Although history was once brilliant, it has long belonged to the past. The shock that The Origin of Species brought to that era cannot be repeated on us. Some people even stand on the opposite side of the Origin of Species to criticize it. The years are silent, and Darwin, who has long since passed away, can no longer stand up and defend himself. However, this does not mean the death of the origin of species. Behind Darwin, there are thousands of supporters of Qian Qian who are firmly on the road of evolution. Perhaps, in Darwin's view, all this has already become unimportant, because his original intention of publishing the Origin of Species was to lead people out of the theological circle and make a deeper reflection on mankind in a broader field. Facts have proved that Darwin succeeded. No matter in the past or now, people are marching on the road opened by the origin of species, arguing about the correctness of evolution, and Darwin in heaven is also smiling. (Wu Xiaoqing)
