Organisms are relatively similar at a molecular level
... Indeed, many types of proteins are found in all organisms. Because of this, we should be able to compare the sequences of amino acids in their proteins to gain an understanding about their relationships. How much similarity in protein sequences would you expect between a whale and a fish? A whale an ...
