Mutation
Mutation is a natural process that changes a DNA sequence. It is when one of the chromosomes is not copy perfectly. It is a random, permanent change in a gene that may or may not be passed on to offspring.
Adaptation
An adaptation is a mutation, or genetic change, that helps an organism, such as a plant or animal, survive in its environment. Due to the helpful nature of the mutation, it is passed down from one generation to the next.
