Which of the following statements is correct? a Individuals do not evolve, genes do evolve. b Populations do not evolve, individuals do evolve. c Populations do not evolve, species do evolve. d Individuals do not evolve, populations do evolve.

d. Individuals do not evolve, populations do evolve.

Explanation:

Evolution is the process according to which organisms have evolved and changed over time. It is the descendant with some modification.

It can also be defines as the gradual change in the pre-existing species to develop a new species over time with some little modifications. Thus we can say that population do evolve when natural selection acts on the genes, but individuals are not evolved.

Hence the correct option is (d).
