From ancient times to the present, there are many views to explain the origin of life, such as the creation of the world in the west, the creation of Pangu in China, and so on. But until the th century, with the publication of Darwin's the origin of species, the biological science has undergone unprecedented great changes. At the same time, it will bring dawn to reveal the eternal mystery of the origin of life, which is the origin of life in modern chemical evolution theory The theory of chemical evolution was first confirmed by the American scholar mill.
In the early days of the earth, because it contained a large number of reducible primitive atmosphere, such as methane, ammonia, water, hydrogen, and primitive oceans, many kinds of amino acids were accumulated in the early stage of the earth due to the action of lightning. However, under normal temperature and pressure, these kinds of amino acids may be concentrated in part, and then further Step by step, proteins and other carbohydrates, as well as high molecular fat, may become pregnant and die in a certain period of time. This is the process of life evolution described by mill.
