Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Flippers of penguins and dolphins are considered homologous organs representing divergent evolution. Reason (R): They have different anatomical origins but have evolved similar functions due to adaptation to a similar aquatic habitat. In the light of the above statements, choose the most appropriat

Options

  1. ABoth Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A)
  2. BBoth Assertion (A) and Reason (R) are true but Reason (R) is not the correct explanation of Assertion (A)
  3. CAssertion (A) is true but Reason (R) is false
  4. DAssertion (A) is false but Reason (R) is true

Correct answer

D. Assertion (A) is false but Reason (R) is true

Step-by-step solution

Assertion (A) is false because flippers of penguins (birds) and dolphins (mammals) do not share the same basic anatomical structure. They are analogous organs, which represent convergent evolution, not divergent evolution. Reason (R) is true because analogous organs are those that have different anatomical origins but perform similar functions as a result of adaptation to the same habitat (in this case, an aquatic environment). Therefore, Assertion (A) is false but Reason (R) is true. Answer: Assertion (A) is false
