In evolutionary biology, what term describes anatomical structures in different species that share a common evolutionary origin despite having different functions?
Answer and explanation
Correct answer: A. Homologous structures
- Step 1: Homologous structures (such as a human arm, bat wing, and whale flipper) derive from a common ancestral tetrapod limb. Answer: Homologous structures. Why not the others: Analogous structures (like bird wings and insect wings) arise via convergent evolution without shared ancestry.
