Vedclass · Answer

(B) Whales,seals,and sharks are distantly related organisms that have evolved similar adaptations to survive in an aquatic environment. Whales and seals are mammals,while sharks are cartilaginous fish. Despite their different evolutionary origins,they all possess a thick subcutaneous layer of fat (blubber) to insulate their bodies against the cold water and to provide buoyancy. This is an example of convergent evolution,where different species develop similar traits due to similar environmental pressures.
