Comparisons of amino acid sequences from different organisms often shed light on the evolutionary divergence of related species. Would you expect all of the proteins of a given set of living species to show the same degree of divergence?

Answer 1

No, you would not expect all of the proteins of a given set of living species to show the same degree of divergence. Different proteins may have evolved at different rates, and some proteins may have evolved more quickly than others. Additionally, some proteins may have been conserved more than others, meaning that they have changed less over time.
