Four requirements for evolution to occur
WebDarwin's theory of natural selection can be expressed as four propositions. These propositions are so important to an understanding of evolution through natural selection that you should try to remember them, … WebIn On the Origin of Species by Natural Selection (1859), Charles Darwin described four requirements for evolution by natural selection: the trait under selection must be variable in the population, so that the encoding gene has more than one variant, or allele. the trait under selection must be heritable, encoded by a gene or genes
