Detailed explanation-1: -Streamlined bodies and fins provide a big advantage for them, allowing them to swim faster. We know that dolphins and sharks are not closely related, and they didn’t inherit their similar body shapes from a common ancestor. Their streamlined bodies, dorsal fins and flippers are the result of convergent evolution.

Detailed explanation-2: -Dolphins and sharks are examples of convergent evolution because they have no recent common ancestors, and yet their bodies have similar shapes.

Detailed explanation-3: -Examples of convergent evolution include the relationship between bat and insect wings, shark and dolphin bodies, and vertebrate and cephalopod eyes. Analogous structures arise from convergent evolution, but homologous structures do not.

Detailed explanation-4: -development in evolution The shark (a fish) and the dolphin (a mammal) are much alike in external morphology; their similarities are due to convergence, since they have evolved independently… Everywhere the environment of Earth is heterogeneous.

Detailed explanation-5: -Whales, sharks and seals have different ancestral origin but they have evolved their limbs for the function of swimming. These limbs are called analogous organs and they point towards a convergent evolution.
