Q1. In the last few decades remarkable fossils have been discovered indicating that the ancestor of cetaceans (whales, dolphins, and porpoises) was a four-legged, terrestrial (land) mammal. Utilize darwin's theory of evolution by natural selection to explain how a group of ancient mammals couple be the ancestors of a major new group of mammals, the cetaceans.

Q2. Evaluation of amino acid sequences can shed light on the evolutionary divergence of related species. Would you expect all proteins of a given set of living species to illustrate the same degree of divergence? Why or why not?
