When the sun first looked down on the earth, the earth was a sea of ??fire. The fire was extinguished in due time according to the laws of physics. From then on, the original basis of life was created according to the laws of physics and chemistry. First, RNA?Ribonucleic acid?was created, then DNA?Deoxyribonucleic acid. RNA or DNA have no life of their own. But they are the oldest basis of life. They are the first. The story of this book could have started from here. But the author has started the story from the idea and discovery of the elements of the original basis of life. So first comes Darwin, who kept the results of his ten years of research secret for twenty years, fearing the scepter, the death penalty. The scientific stir that his classic science book, ?Origin of Species? and the theory of Survival of the Fittest, created in the world of human thought soon transformed into a revolution. After this, scientists did not have to stop in their larger exploration of the evolution of the biological world. The preparation and flow of the origin of life have been discovered. Based on Darwin's theory, a basic rule has been established by passing through the world of cells, the world of genes, and arriving at the world of RNA and DNA. In this book, the author has recorded the history of this long journey of the scientific world in simple and easy language. Due to the quality of presentation, the entire book seems to be a combination of classical science and classical literature.
