Are you saying that human beings cannot be improved?  Has nature
produced her finest organisms?   This is an interesting
assertion.  However, we must keep in mind that evolution occurs
on a time scale of millions of years.  For example, imagine that
there is a food shortage in the future and human beings must
compete more intensely to survive.  In this case, perhaps only
the strongest or most intelligent could survive.  Isn't this
evolution at work?  I am not implying that intelligence is soley
genetic based, but it is likely to be true to a certain degree.
Just as we are evolved from apes, I believe humans of the
distant future could be more highly intelligent than present
