Explanation:

Evolution deals with history of organism survival on Earth.

The evolutionary biologists makes use of fossils as proves to give light to having a clear view of how species survived in past times.

Before the theory of natural selection by Charles Darwin, Evolutionary Biologists were filled with questions about why the type of skeletal structural specimens collected were equal and different in dissimilar organisms as it does not exhibit the links seen between these species.

The theory of evolution proposed the mechanism of divergent evolution as a solution to these questions.
