(d) Adaptive radiation
Show Answer
Answer : d
Hints & Solution
(d) The correct option is (d) because flippers of Penguins and Dolphins are an example of analogous organs. Analogous structures are a result of convergent evolution. The concepts underlying convergent evolution can be traced back to Richard Owen, a British biologist who, despite doubting Darwin’s theory of evolution, in the mid 1800s pointed out the difference between animals with body parts that are built similarly (homologues) and body parts that just have similar purposes.
