Detailed explanation-1: -Evolution is the process by which populations of organisms change over generations. Genetic variations underlie these changes.

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: -Darwin’s theory of evolution describes evolution as a slow, gradual continuous process of change. This could mean that evolutionary changes could occur over thousands or hundreds of thousands of years. It is so gradual that one cannot detect these changes in a lifetime, or even over several generations.

Detailed explanation-4: -Individual organisms can evolve during a single lifespan. Evolution only occurs slowly and gradually. Because evolution is slow, humans cannot influence it.

Detailed explanation-5: -Summary: Evolution is usually thought to be a slow process, something that happens over generations, thanks to adaptive mutations. But environmental change is happening very fast.
