Question
Long answer question.
Would you consider wings of butterfly and bat as homologous or analogous and why?
Solution
The wings of butterfly and bat are analogous but not homologous.
Examples of analogous structures are as follows:
1. Wings of butterfly (insects) and of birds look superficially alike but they are not anatomically similar structures though they perform similar functions.
2. Eye of the octopus (mollusca) and of mammals. They differ in their retinal position, the structure of lens, and the origin of different eye parts.
3. The flippers of penguins (birds) and dolphins (mammals).
4. Sweet potato (root modification) and potato (stem modification) store food in form of starch.
