The theory of evolution is one of the fundamental keystones of modern biological theory. Darwin realized that population explosions would lead to a struggle for resources and that the ensuing competition would weed out the unfit. It was an idea he now applied to nature (he had previously thought that animal populations remained stable in the wild). Darwin called his modified Malthusian mechanism “ natural selection.”
