Question

Analogous structures indicates evolution while homologous structures indicate evolution.

• A. divergent
• B. convergent
• C. branched
• D. linear

Answer 1

Answer: (A), (B)

convergent

Analogous organs are those organs which are structurally different and functionally similar in unrelated groups of organisms. Analogous structures are a result of convergent evolution suggesting that different structures evolve for the same function.

Homologous organs are those organs which are structurally similar but functionally different. They are originated from a common ancestor. Homologous organs indicate divergent evolution suggesting that same structures developed along different directions due to adaptations to their different needs.
