evolution /evo·lu·tion/ (ev″ah-loo´shun) a developmental process in which an organ or organism becomes more and more complex by differentiation of its parts; a continuous and progressive change according to certain laws and by means of resident forces. convergent evolution the appearance of similar forms and/or functions in two or more lines not sufficiently related phylogenetically to account for the similarity. organic evolution the origin and development of species; the theory that existing organisms are the result of descent with modification from those of past times.
convergent evolution, the evolution of nonhomologous organs in distantly related species in response to similar environmental conditions. Although of different origin, the organs appear similar in function, shape, or form. evolution the process of development in which an organ or organism becomes more and more complex by the differentiation of its parts; a continuous and progressive change according to certain laws and by means of resident forces. convergent evolution the development, in animals that are only distantly related, of similar structures or functions in adaptation to similar environment. divergent evolution the development of different characteristics in animals that were closely related in response to being placed in different environments.

However, additional typing methods would be required to verify that the strains are related, rather than exhibiting convergent evolution of their respective spoligotypes. However, several features of Incisivosaurus suggest that Caudipteryx and other oviraptors developed their avian features not through inheritance from birds but through convergent evolution. Nevertheless, taxonomists have found some physical pointers hinting that the similarities arise from coincidence, or convergent evolution, and not shared ancestry. |
