Convergent evolution involves the independent development of similar structures in the organisms that are not directly related. It is represented by analogous organs. Analogous organs are the structures, which are different in their basic structure and developmental origin but appear similar and perform similar functions. This relationship between the structures of different groups of animals due to their similar functions is called analogy or convergent evolution.
Examples- Insect and bird wings are different in basic structure and origin because insect wing is formed from integument, while the bird's wing is a modified forelimb. These are analogous organs because both are flat structures and are well adapted for flight.
Hence, the hummingbird, hawk and the humming moth represent the analogous organs and thus, convergent evolution
So, the correct answer is 'Convergent evolution'
