What is the difference between evolution and natural selection?
Evolution is a scientifically accepted theory of the origin of present organisms from ancestors of the
past, through a process of gradual modification. Natural selection is an explanation of how such changes
might have occurred, i.e., the mechanism of evolution.
The concept of evolution existed among the Greeks of Athens. In the eighteenth century, the French
naturalist Comte Georges de Buffon suggested that species may undergo change and that this may have
contributed to the diversity of plant and animal forms. Erasmus Darwin, grandfather of Charles, also
subscribed to the concept of changes in the lineage of most species, although his ideas do not seem to
have played a role in the development of Charles Darwin’s concept of evolutionary change.
The first comprehensive theory of a mechanism of evolution was advanced by Lamarck in 1801. Like
Charles Darwin, Lamarck was profoundly influenced by new findings in geology, which suggested that the
earth was extremely old and that present-day geological processes operated during past millennia.
