For natural selection to occur, organisms *must* vary in their characteristics within a species. Variation is the raw material upon which selection acts.<\/section>\n
The necessary conditions for natural selection are: variation among individuals, inheritance of variation, differential survival and reproduction based on that variation, and often, limited resources leading to competition (more offspring born than can survive).<\/section>\n
If there were no variation within a species, all individuals would be identical, and there would be no basis for differential survival or reproduction based on traits, thus no natural selection leading to evolutionary change.<\/section>\n","protected":false},"excerpt":{"rendered":"
