definition: Charles Darwin was never entirely satisfied with the evolutionary role he originally gave to natural selection in On the Origin of Species. He later expressed reservations about attributing too much of evolution to the action of natural selection and survival of the fittest because he became convinced that nonfunctional structures evolving without natural selection could later prove to be useful and therefore come within the range of natural selection.
