multiple choice 4.15 points which of the following explains the similarity in form of the dolphins and the sharks dorsal fin? evolutionary reversal evolutionary convergence none of the above homology

Answer

Brief Explanations:

Evolutionary convergence occurs when different species independently evolve similar traits due to similar environmental pressures. Dolphins and sharks have similar - shaped fins (dorsal fins) because they both live in aquatic environments and need to swim efficiently. This is an example of evolutionary convergence. Evolutionary reversal is the reappearance of an ancestral trait. Homology refers to traits inherited from a common ancestor, and dolphins are mammals while sharks are fish, so their fins are not homologous.

Answer:

B. Evolutionary Convergence
