What does analogy refer to in evolutionary terms?

Step-by-step solution

Analogy refers to different structures that evolve to perform similar functions, resulting from convergent evolution. 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
