Question
Biology Question on What Are The Evidences For Evolution?
Parallelism is
A
adaptive divergence
B
adaptive divergence of widely separated species
C
adaptive convergence of widely different species
D
adaptive convergence of closely related groups.
Answer
adaptive convergence of closely related groups.
Explanation
Solution
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.
