8. Which of the following statements are part of the Theory of Natural Selection? • Individual organisms change in response to their environment. • Variations are found among the members of a species. • Not all of the young in each generation will survive. • If an organism uses a structure more the structure will be more developed and that trait can be passed on to their offspring.
