Quizplus · Accepted Answer

Charles Darwin was heavily influenced by Thomas Malthus' book, An Essay on the Principle of Population, in which Malthus argued that population growth would inevitably outstrip food production, leading to a "struggle for existence" in which only the fittest individuals would survive and reproduce. This idea of a "struggle for existence" became a key concept in Darwin's theory of evolution by natural selection.
