Natural selection is the process by which

• change occurs in the genetic characteristics of individuals that live together in an environment from one generation to another
• organisms with traits well-suited to their environment reproduce at a greater rate than less well-adapted organisms in the same environment
• use and disuse of a characteristic leads to evolutionary change
• baseball players pass on the trait for strong arm muscles to children
