4.* * * Homoancestor: All life has a * * * ancestor, and all species have evolved.
The influence of evolution
Darwin's theory of evolution has become the basis of modern biology and medicine, and has had a far-reaching impact on the theory and practice of biology and medicine. The success of the theory of evolution shows the effectiveness of scientific methods in natural science research and encourages the application of scientific methods in other fields. It has had an important influence on social science, philosophy and humanities; The application of evolution theory in social science, philosophy, humanities and other fields has had a far-reaching impact.
