5 principles of natural selection
Understanding: • Natural selection increases the frequency of characteristics that make individuals better adapted and decreases. the frequency of other characteristics leading to changes within the species. The theory of natural selection was posited by Charles Darwin (and also Alfred Wallace) who described it as ‘survival of the fittest’.Selection and adaptation can occur at multiple levels. Evolution by natural selection can occur at any level of biological organization, so long as the requisite ingredients are in place: heritable variation among entities that differ in fitness (Keller 1999). These entities can be species, populations (groups), families, individuals, genes, or ...
