No, it's the other way around: descent with modification is what you need for natural selection to happen.
Natural selection.
Biogeographic observations indeed suggest that a evolutionary process caused new species to arise, through the process we call natural selection. This is due to an animals adaptability in it's environment.
Natural selection with modification of traits. He could explain natural selection, however he had no explanation for modification of the traits from generation to generation (this had to wait for Gregor Mendel's theory of genetics, and the later discovery of nucleic acids and Watson and Crick's study of DNA to explain the storage of genetic information chemically).
accelerated rates of natural selection due to human involvement.. natural selection caused by human intervention.
differential reproductive success caused by genetic variation is necessary for the process of natural selection.

Natural selection and artificial selection both involve an organism's traits being determined by how much they're favored. Then, the organisms with favorable traits pass those traits on to future generations.However, natural selection is caused by survival; the organisms with traits that increase their chances for survival and reproduction pass on their traits. As for artificial selection, humans purposefully decide which traits (like the most colorful one) of an organism to pass on.The similarity of artificial selection and natural selection is that they both can cause changes in the frequency of population.
