Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Development of similar adaptive functional structures in unrelated groups of organisms is called convergent evolution. It shows analogy. Examples are wings of butterfly and birds, eyes of octopus and mammals, flippers of penguins and dolphins, etc. On the other hand, divergent evolution involves the modification of organs to perform different functions as an adaptation to different environments. For example forelimbs of vertebrates (whales, bat, cheetah, human). Though these perform different functions, they have similar anatomical structure.

Evolution
Evolution is a process that occurs in changes in the genetic content of a population over time. Evolutionary change is generally classified into two: microevolution and macroevolution. The process of changes in allele frequencies in a population over time is a microevolutionary process. Three main mechanisms that cause allele frequency change are natural selection, genetic drift, and gene flow. On the other hand, macroevolution refers to change at or above the level of the species.
