Which of the following statements is not true?
Analogous structures are a result of convergent evolution
Sweet potato and potato is an example of analogy
Homology indicates common ancestry
Flippers of penguins and dolphins are a pair of homologous organs
Option (4) 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 (3), (1) and (2) 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.
