Class 12 NEET Biology Evolution Questions Part 1

Development of similar adaptive functional structures in unrelated groups of organisms is called adaptive convergence or convergent evolution e.g. wings of insect, bird and bat show marked convergent evolution. When convergent evolution is found in closely related species, it is called "Parallel evolution". Example : development of running habit in deer (2 -toed ) and horse (1− toed ) with two vestigial splint bones.
