Detailed explanation-1: -Darwin proposed that species can change over time, that new species come from pre-existing species, and that all species share a common ancestor. In this model, each species has its own unique set of heritable (genetic) differences from the common ancestor, which have accumulated gradually over very long time periods.
Detailed explanation-2: -Evolution: Changing Species Over Time Evolution is the process by which species adapt over time in response to their changing environment.
Detailed explanation-3: -Clearly, he did not invent the idea. That happened long before he was born. However, he carried out the necessary research to conclusively document that evolution has occurred and then made the idea acceptable for scientists and the general public.
