The Avatars, basically, refers to the descending order from simple life form to more complex life forms. It can be seen as the reflection of the modern Darwinian theory of evolution, that is, the most sophisticated life as a human has been evolved through a long process of development of life. Avatars, to some extent, support the Darwinian theory of evolution. Our ancestors taught us about evolution, which The Jai Jais share in our Dashavatars in a form simple and easily understandable stories. They are symmetrical to Darwin’s theory of evolution. This shows that Indian Rishis and Sages, no less than modern day scientists, were aware of the theory of evolution of life, some people say much before Charles Darwin introduced it to the world.
