The Organic Evolutionary theories explain convincing the origin of life. It also explains how a wide variety of plants and animals came into existence in the world. According to this theory, the world has been evolved and not been created.
The theories of evolution is explained in 4 types. They are
- Theory of inheritance of acquired characters (Lamarckism)
- Theory of natural selection (Darwinism)
- Modern synthetic theory of evolution,
- Weismanner’s germ plasma theory,
- Hugo DeVries “mutation theory”
