In a specimen-based viva, the examiner describes this case: insect wings and bird wings both support flight but evolved independently. Choose the concept that fits it best.

Correct Answer: C

analogous structures

Analogous structures perform similar functions but do not share the same evolutionary origin. They result from convergent evolution and should be used cautiously in phylogenetic classification. This MCQ belongs to the Phylogeny topic in Animal Diversity-I and is written to test concept understanding rather than memorized wording.
