Solution
The correct option is C Divergent evolution
The structures which are similar in their morphology, anatomy, genetics and embryology but dissimilar in their function are called as homologous organs. Many mammals have similar limb structures. The flipper of a whale, the wing of a bat, and the leg of a cat are all very similar to the human arm. Divergent evolution is the accumulation of differences between groups, which can lead to the formation of new species, usually a result of diffusion of the same species to different and isolated environments, which blocks the gene flow among the distinct populations allowing differentiated fixation of characteristics through genetic drift and natural selection.
