Answer:
Option (A)
Explanation:
Convergent evolution may be defined as the independent evolution of similar features in different species. This evolution shows analogous structure that perform similar function but do not have a common ancestor.
Penguins, sea turtles and manatees forelimb is an example of convergent evolution because similar forelimb structure evolution has occurred in different species lineage. The convergent evolution of forelimb structure in these species permit movement in water.
Thus, the correct answer is option (A).
