ABSTRACT

The Evolution of Darwin is brought about by the Struggle for Existence. It was the theory of Malthus that the food-supply regulated the life-supply. Malthus was the man to broach the idea, but applied it only to mankind. Darwin took over his theory and applied it to all organic life. Darwin imagines the variation to be a condition precedent, or subsequent, to the struggle for existence: but when once the variations are set in motion they become alternately conditions precedent, and subsequent to the struggle for existence in the various specie. So, strictly speaking, Darwin’s theory is nothing more than the method by which evolution works, or a preservative agent of the innumerable favourable variations which the struggle for existence induces. Darwin’s contention is that certain favourable varieties appear from time to time, both in the individual and the species, induced by the struggle for existence.
