Webb3 feb. 2024 · In order for natural selection to occur in a population, several conditions must be met: Individuals in the population must produce more offspring than can survive. Human beings are somewhat unique among living things in that we can make conscious choices about how many offspring we have. Webb9 juli 2024 · “Darwin’s theory of evolution stated that all species develop through the natural selection of small, inherited variations that increase the individual’s ability to compete, survive, and reproduce,” says lead researcher David Hugh-Jones, a professor from UEA’s School of Economics, in a university release.
