<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.
