Darwin recognized the process of evolution (natural selection). Correct. Darwin's greatest contribution to science is that he recognized that the process of evolution (natural selection) could explain the pattern of evolution (descent with modification). Evolution by natural selection is considered to be the organizing principle of biology-----
Since Darwin's day, science has made astounding advances in the ways in which it can study organisms. One of the most useful advances has been the development of molecular biology. In this field, scientists look at the proteins and other molecules that control life processes. While these molecules can evolve just as an entire organism can, some important molecules are highly conserved among species.
