The evolution of life is a continuous biological process. There is a basic principle of evolution and different theories have been put forward to explain how evolution has occurred. Principles of evolution are evolution is a very complex, reversible, and extremely slow process, evolution is not always progressive, evolution proceeds at a different rate in a different kind of organism, evolution takes place more quickly at a certain time than at others, the new species are always better adapted than their ancestors, etc. The different theories of evolution are the theory of Inheritance of acquired characters, the theory of natural selection, the mutation theory of DE Vries, and the synthetic theory of evolution.
