The correct option is C Convergent evolution
Development of similar adaptive functional structures in unrelated groups of organisms is called convergent evolution. Examples include the wings of insect, bird and bat, which have different origins (the animals being part of different taxonomic groups) and yet, perform the same function - flight. Thus analogous organs show convergent evolution (adaptive convergence). Development of different functional structures from a common ancestral form is called divergent evolution, as seen in the case of homologous organs. Microevolution produces minute changes below the species level. Macroevolution involves the evolution of species and genera or differentiation of groups of animals by adaptive radiation.
