Which of the Following Statements About Evolution is True

Question

Which of the following statements about evolution is true?
A) Evolution involves maintaining a constant frequency of alleles in the gene pool.
B) Populations evolve.
C) Individuals evolve.
D) Evolution can proceed to a limited extent without the occurrence of mutation.

Accepted Answer

Populations evolve over time as the frequency of alleles in the gene pool changes through processes such as mutation, natural selection, genetic drift, and gene flow. Individual organisms do not evolve, but rather their traits may represent adaptations to their environment that increase their fitness and likelihood of survival and reproduction. Additionally, evolution cannot occur without genetic variation, which is often generated through mutation.
