Detailed explanation-1: -Malthus’ work made Darwin realize the importance of overpopulation and how it was necessary to have variability in different populations. Darwin also used Malthus’ ideas to use competition as well as the survival in numbers idea to come up with his full idea of natural selection.
Detailed explanation-2: -In 1838, Darwin read Malthus’ essay and came to realize that all plant and animal populations have this same potential to rapidly increase their numbers unless they are constantly kept in check by predators, diseases, and limitations in food, water, and other resources that are essential for survival.
Detailed explanation-3: -Darwin recognized that many plant and animal species produced far more offspring than could survive. Upon reading Malthus, he surmised that the large numbers of offspring are produced in a biological gamble.
Detailed explanation-4: -A.2. The Malthusian theory explained that the human population grows more rapidly than the food supply until famines, war or disease reduces the population. He believed that the human population has risen over the past three centuries.
