Darwin realized that Malthus's theory of population control could be generalized to any population of organisms.
Thomas Malthus's idea of population growth outstripping resources and causing competition for survival influenced Darwin's theory of natural selection. Darwin applied this concept to the natural world, suggesting that individuals with advantageous traits would be more likely to survive and reproduce, passing on those traits to future generations.
