Quizplus · Accepted Answer

Natural selection is the most important force in shaping evolution because it is the mechanism by which traits that increase an organism's fitness become more common in a population over time. This results in the gradual adaptation of species to their environment. Biological research can contribute to our understanding of evolution, but it does not drive the process itself. Random events, such as genetic drift, can also play a role in evolution, but they are not as consistent or predictable as natural selection. The fixity of species is an outdated concept that has been disproven by scientific evidence.
