Question

Sol.(d) [Key Concept: Homologous Organs — Man/Bat/Seal Forelimbs] Hand of man, wing of bat, and flipper of seal are homologous organs. They all share the same basic pentadactyl limb structure with the same bones (humerus, radius, ulna, carpals, metacarpals, phalanges) derived from the same embryonic origin (vertebrate forelimb), but have been modified for different functions (grasping, flying, swimming).
