Mutations can be considered as one of the raw materials of evolution because they:
1) contribute to new variations in organisms
2) are usually related to the environment in which they appear
3) are usually beneficial to the organism in which they appear
4) usually cause species of organisms to become extinct
1 because mutations mean that a different trait will be present in the organism. If the mutation is helpful, the organism will be able to survive and reproduce and their offspring will contain the trait
