1. rhesus

2. pigeon

3. fruit fly

Evolution can be described as the process in which different organism evolve from common ancestors over a long period of time. Evolutionary studies show that some organisms have more shared characteristics as compared with other organisms. These organisms with common characteristics are believed to be closer to one another and evolved from the same ancestors.

In the above question, as there is only one difference between the cytochrome c of humans and rhesus, hence rhesus is the closest to humans. Pigeons has lesser number of differences than fruit fly, hence it is second on the list. Fruit fly has the maximum differences hence it is placed last.
