<P> Convergent evolution is the independent evolution of similar features in species of different lineages . Convergent evolution creates analogous structures that have similar form or function but were not present in the last common ancestor of those groups . The cladistic term for the same phenomenon is homoplasy . The recurrent evolution of flight is a classic example , as flying insects , birds , pterosaurs , and bats have independently evolved the useful capacity of flight . Functionally similar features that have arisen through convergent evolution are analogous , whereas homologous structures or traits have a common origin but can have dissimilar functions . Bird , bat , and pterosaur wings are analogous structures , but their forelimbs are homologous , sharing an ancestral state despite serving different functions . </P>
