Answer;
Thomas Robert Malthus
Explanation;
-Charles Darwin was influenced by many writers, scholars, philosophers, and friends. One of his influences was Thomas Robert Malthus, a late-eighteenth century economist. Malthus wrote "Essay on the Principle of Population" (1798), which Darwin read and was inspired by.
-The central theme of Malthus' work was that population growth would always overpower food supply growth, creating perpetual states of hunger, disease, and struggle. The natural, ever-present struggle for survival caught the attention of Darwin, and he extended Malthus' principle to the evolutionary scheme.
