Analogous organs arise due to

1. divergent evolution

2. artificial selection

3. genetic drift

4. convergent evolution

(d) Analogous organs arise due to convergent evlolution. These are the organs which have

similar function,s but are different in their structural details and orgin, e.g., wings of insect and

bird.

The other three option are incorrect, because divergent evolution give rise to homologous, organs

genetic drift can contribute to speciation and artifical selection is used to produce improved

varieties of animals and plants.
