Detailed explanation-1: -Adaptations develop when certain variations or differences in a population help some members survive better than others (Figure below). The variation may already exist within the population, but often the variation comes from a mutation, or a random change in an organism’s genes.

Detailed explanation-2: -A mutation is a naturally occurring variation in the gene sequence. An example could include darker colored mice being born to lighter colored mice. An adaptation is a way an organism changes as it responds to changes in its environment.

Detailed explanation-3: -Explain how a mutation might lead to an adaptation. Mutations may change the behavior or physical traits of an organism. These changes may help the organism to survive in its environment or surroundings which is passed down from one generation to the next. Therefore, the mutation has led to an adaptation.

Detailed explanation-4: -Mutations can be harmful, neutral, or sometimes helpful, resulting in a new, advantageous trait. When mutations occur in germ cells (eggs and sperm), they can be passed on to offspring. If the environment changes rapidly, some species may not be able to adapt fast enough through natural selection.
