Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations. Charles Darwin popularised the term "natural selection", contrasting it with artificial selection, which is intentional, whereas natural selection is not. WebA persistent misconception is that natural selection occurs mainly through differences between organisms in death rates, or differential mortality (e.g. “Nature, red in tooth and claw”). Selection normally proceeds in a much more subtle and inconspicuous way. optiplex micro wall mount
