Then it suddenly flashed upon me that this self-acting process would necessarily improve the race, because in every generation the inferior would inevitably be killed off and the superior would remain - that is, the fittest would survive. Then at once I seemed to see the whole effect of this, that when changes of land and sea, or of climate, or of food-supply, or of enemies occurred - and we know that such changes have always been taking place - and considering the amount of individual variation that my experience as a collector had shown me to exist, then it followed that all the changes necessary for the adaptation of the species to the changing conditions would be brought about; and as great changes in the environment are always slow, there would be ample time for the change to be effected by the survival of the best fitted in every generation.
In this way every part of an animal's organization could be modified exactly as required, and in the very process of this modification the unmodified would die out, and thus the definite characters and the clear isolation of each new species would be explained. The more I thought over it the more I became convinced that I had at length found the long-sought-for law of nature that solved the problem of the origin of the species.

The same evening I did this pretty fully, and on the two succeeding evenings wrote it out carefully in order to send it to Darwin by the next post, which would leave in a day or two.
I wrote a letter to him in which I said I hoped the idea would be as new to him as it was to me, and that it would supply the missing factor to explain the origin of the species. I asked him if he thought it sufficiently important to show it to Sir Charles Lyell, who had thought so highly of my former paper. The spotless integrity of his principles, the equity and candour of his nature, his sweetness of temper, urbanity of manners, and tenderness of heart, his benevolence and his piety, are the still dearer recollections of his family and friends.

The result of this would be the formation of a new species. Here, then, I had at last got a theory by which to work. Today, years after Malthus first published his ideas, his message remains prophetic. Epidemics may be less lethal and crops more abundant, but populations are still outstripping food production in many parts of the world, and wars remain as destructive as ever.
