Darwin’s theory of evolution is as follows:
- Individuals of every species can produce a large number of progenies. But not two individuals look alike.
- More number of individuals results in intense competition for various resources like food, shelter and other resources.
- Only the fittest individual survives in this competition and others perish.
- Nature selects those traits which make an individual fit to survive. Such individuals are able to produce more progenies and thus desirable characters are inherited in subsequent generations.
- A new species evolves through this process in due course of time.
