Analogous organs

Vedclass · Answer

(B) The diagram shows the pectoral fin of a shark and the flipper (forelimb) of a dolphin.Analogous organs are those that perform similar functions but have different anatomical structures and different developmental origins.The pectoral fins of sharks and the flippers of dolphins are classic examples of analogous organs.While both are adapted for swimming,their internal skeletal structures are fundamentally different; the shark's fin lacks the pentadactyl limb structure found in the dolphin's flipper.Therefore,they represent convergent evolution,not divergent evolution.
