This is an analysis question for a lab on the amino acid differences in beta globin amongst different primates, and using such differences to construct a cladogram and infer evolutionary relationships from it. Any input is greatly appreciated!
Question: What do you see as the strengths and weaknesses of using amino acid structure of proteins for evolutionary analysis? In your opinion, would it be more useful to use DNA sequences for this type of evolutionary comparison between living and extant species? Why or why not?
