DEFINITION AND EXAMPLES:
A mutation is a change in the DNA, the hereditary material of living things. The DNA of an organism influences on their physical appearance, behavior and physiology. Therefore, a change in the DNA of an organism can cause changes in all aspects of your life.
Mutations are random, that is, totally random. These can be beneficial, neutral or harmful to the body, but do not try to provide what the body needs. The risks may increase with mutagenic agents; solar rays, chemicals and environmental pollutants.
Also, not all mutations are relevant to evolution as all our body cells contain DNA and there are plenty of places where you can cause mutations but without relevance. The somatic mutations are those that occur in the cells not breeders and are not transmitted to offspring.
The only mutations relevant to large-scale evolution are those that can be transmitted to offspring. Such mutations are those that occur in the cells are reproducing and germinal mutations.
