Question
A student is revising Animal Diversity-I: two animals have appendages with the same evolutionary origin but different present-day functions. What should the student write in the answer sheet?
Correct Answer: C
homologous structures
Homologous structures share a common evolutionary origin even if their functions differ. Such characters are important in reconstructing phylogenetic relationships among animal groups. This MCQ belongs to the Phylogeny topic in Animal Diversity-I and is written to test concept understanding rather than memorized wording.
