1. Evolution is the process by which species adapt over time in response to their changing environment.
2. The changes caused by mutation affect the function of a gene or an entire chromosome.
3. These may also lead to new genes, which may have an advantages
4. So a alter in an organism's DNA can cause changes in all aspects of its life. Mutations are important to evolution
