Explanation:
Individuals adapt to their environments and, thereby, evolve
Explanation:
Natural selection is the main process which advances evolution by aiding organisms to survive and produce more offspring through adapting more to their environment. Mutations, gene transfer, and genetic variations also drive evolution.
Both natural selection and evolution work on genetic behaviors in populations rather than individuals. Both natural selection and evolution are involved in generating changes over generations. Examples of evolution is the disappearing of tail bone, decreased head size and for natural selection example is the long and short necked giraffe.
