About 1859, the Origin of Species, which shocked the academic circles at that time, was officially published. He used a lot of materials to prove that all kinds of creatures were not created by God, but from the aspects of heredity, variation, struggle for existence and natural selection. Moreover, the content of this book is constantly changing, from simple to complex, from low to high, because he put forward the theory of biological evolution, thus destroying all kinds of idealistic creationism and theories.
Engels listed the theory of evolution as one of the three major discoveries of natural science in the19th century, and the other two were cytology theory, energy conservation and transformation law. His natural selection and sex selection are consistent and universal theories in current life sciences, and besides biology, his theories are actually very important to anthropology, psychology and philosophy. This theory of biological evolution, even the whole biological science, started with 1859.
After 20 years of careful preparation, Darwin published the Origin of Species, and his first edition printed 1250 volumes. However, it was sold out in less than a day, that is, when a brand-new discipline was born. However, a new theme did not fall from the sky, it was mastered by the scientific community around 1859.
Darwin or Wallace, who first raised the question of evolution, will explain it here today.
