 AB    Convergence as a phenomenon in molecular evolution is an issue that
       confuses many discussions. Often the problem is that not enough care is
       taken to state exactly what kind of convergence one has in mind.
       Functional and mechanistic convergence are both common, and some
       structural convergence has probably occurred, but a convincing case for
       genuine sequence convergence has yet to be made.
