As the starting point for our discussion of what natural selection is, it is convenient to consider Darwin’s famous book The Origin of Species. The full title of this book including the subtitle is On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life. We can gather from this that the theory of natural selection forms the basis of Darwin’s theory. This book was published when Darwin was 50 years old; stimulated by A. R. Wallace’s paper on natural selection, the results of his researches, tirelessly continued for 22 years after returning from the circumnavigation of the globe on the Beagle, were made public in the form of a compendium.
