Question

Q. Which of the following is not an example of convergent evolution?

• A. Wings of bat and insect
• B. Stimulants in coffee and tea
• C. Claws of Armadillos and Pangolin
• D. Thorn of Bougainvillea and Tendrils or Cucurbita

Answer 1

The correct option is D Thorn of Bougainvillea and Tendrils or Cucurbita

Explanation:

Divergent evolution or divergent selection is the accumulation of differences between closely related populations within a species, leading to speciation. Thorns of Bougainvillea and tendrils of Cucurbita are homologous organs. These are modified branches and are axillary in position. It means axillary branches in Bougainvillea are modified into thorns for protection from burrowing animals and in Cucurbita into tendrils for climbing. All others are examples of convergent evolution.
