Read the following statements and choose the following option: 1. The same structure developed along different directions due to adaptations to different needs indicates divergent evolution 2. Homology indicates common ancestry. 3. Wings of butterfly and of birds are not anatomically similar structures though they perform similar functions. 4. The eye of the octopus and of mammals or the flippers of Penguins and Dolp

Step-by-step solution

Homology is based on divergent evolution whereas analogy refers to a situation exactly opposite. Wings of butterfly and of birds look alike. They are not anatomically similar structures though they perform similar functions. Hence, analogous structures are a result of convergent evolution - different structures evolving for the same function and hence having similarity. Other examples of analogy are the eye of the octopus and of mammals or the flippers of Penguins and Dolphins. One can say that it is the similar ha
