Homologous and Analagous Structures

Comparative Morphology Analogous Structures Structures with similar function but different internal structure, development (bird wing and insect wings, dolphin fin and shark fin) Does NOT show evolutionary relationships Why similar in structure?

Comparative Morphology- Homologous Structures Structural similarities among organism Homologous structures – similar structure, different function (dog leg, whale flipper, Bird wing) Shows evolutionary relationship, origin
