Which of the following statements is not true?

  1. A
    Analogous structures are a result of convergent evolution
  2. B
    Sweet potato and potato is an example of analogy
  3. C
    Homology indicates common ancestry
  4. D
    Flippers of penguins and dolphins are a pair of homologous organs
View written solutionFree

Correct answer: D

Option (d) is the correct answer because flippers of penguins and dolphins are analogous organs as they help in swimming but do not have the same structure.

Option (c), (a) and (b) are true statements and hence cannot be the correct answer.

Homologous organs have the same structure but have different functions according to the needs of the organisms. Hence, homology indicates common ancestry.

Analogous structures have developed for the same function but do not show a similarity in structure. Hence, they are a result of convergent evolution.

Sweet potato is a root modification for food storage whereas potato is an underground stem modification for storage. Hence they are analogous.
