<h2>Natural selection </h2>

Explanation:

Malthus's ideas about geometric population growth implied that: resources in every generation would be limited, therefore individuals in every generation would have to compete for those resources

  • Thomas Malthus argued that the food supply increased linearly while  population size increased exponentially
  • 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
  • Malthus’ writings ultimately inspired Darwin’s  theory of evolution by natural selection

resources in every generation would be limited, therefore individuals in every generation would   have to compete for those resources.
