Which of the given examples show convergent evolution?
i) Wings of butterfly and of birds
ii) Flipper of Penguin and Dolphins
iii) Eye of the octopus and of mammals

i, ii and iii

The correct answer is Option (1)- i, ii and iii

Analogous organs: The organs which have similar functions but are different in anatomical structures are called analogous organs which is a result of convergent evolution.

i) Wings of butterfly and of birds
ii) Flipper of Penguin and Dolphins
iii) Eye of the octopus and of mammals
All these structures are analogous to each other and hence show convergent evolution.
