Q. Choose the correct statements with reference to organic evolution.
I. Flippers of whale and wings of bat exhibit analogy.
II. Wings of butterfly and wings of bird exhibit homology.
III. Organs with dissimilar structure are called analogous organs.
IV. Organs with similar stmcture and origin are called homologous organs.

Evolution

Solution:

Statements III and IV are correct for organic evolution, while statements I and II are incorrect. It can be corrected as
• Homologous structures have the same embryonic origin and basic structure, but they do not perform same function, e.g. flipper of whale and wings of bat.
• Analogous organs are the structures which are different in their basic structure and developmental origin, e.g. wings of butterfly and wings of bird.
