Final answer:
The steps that occur during natural selection in the correct order are: a change occurs in the population's environment, individuals who are well-adapted leave more offspring than individuals who are poorly adapted, individuals who are poorly adapted do not survive at the same rate as individuals who are well adapted, genetic frequencies within the population change, and phenotypic variations shift.
Step-by-step explanation:
A change occurs in the population's environment.
Individuals who are well-adapted leave more offspring than individuals who are poorly adapted.
Individuals who are poorly adapted do not survive at the same rate as individuals who are well adapted.
Genetic frequencies within the population change.
Phenotypic variations shift.
