MCQ
Analogous organs arise due to:
  • A
    Divergent evolution.
  • B
    Artificial selection.
  • C
    Genetic drift.
  • D
    Convergent evolution.
✓

Answer

  1. Convergent evolution.

Organs having different origin but similar function are called analogous. Wings of butterfly and of birds look alike. They are not anatomically similar structures though they perform similar functions. Hence, analogous structures are a result of convergent evolution-different structures evolving for the same function and hence having similarity.
